Go on amazon or any hardware website and buy yourself some folding steel bollards. Install them when the offending vehicle is not there and lock them in place whilst you're at work to prevent them stealing your parking spaces.

I installed some to stop people using my drive whilst doing the school run. I live near a school and people seem to think that means they have a right to park on other peoples driveways if they're dropping off or picking up their kids.

Isn't the Model S freakin amazing! It's smooth and beautifully designed.

This type of attack is being reported in the news over and over again - it's very much a problem and even happened to my cousin. When I saw it I got a fob faraday bag. OP posted the bag for $20 on Amazon but in my opinion that bag is NOT worth it. It's far too small to hold my entire key set and it failed on me after a month of use - very disappointing.

I got another bag on Amazon and it has worked like a charm. It's a little more expensive but if im going to buy one of these bags I want it to actually work. It's been two months and this bag is working strong. It gives me peace of mind.

Actually it's pretty ridiculous we need to buy these things I feel like the car manufacturer should find a way to stop this. Anyway I'll report back later if the bag has any issues.

Update: Yes as a few people mentioned this is the mission darkness keyfob bag.

Onvian Wireless Anti-Theft Motorcycle Bike Alarm with Remote, Waterproof Bicycle Security Alarm Vibration Sensor, 113dB Loud

I just have it attached on the steer tube. Another cool feature (at least I thought) it has a fall detect when it is off, so if I end up running off the side of the road maybe someone will hear the alarm and come get my body.

u/boaratio · 17 pointsr/baltimore

First, sorry to hear that your car was stolen. That would make anyone feel awful. No one likes to feel like they're not in control - and being robbed of anything takes away that feeling of control.

Second, I'm sure you locked your car. This jackass most likely had a key fob range extender that just amplifies the signal from your house so the car thinks the keys are nearby. Auto manufacturers should be ashamed that their RF signals are one direction only, instead of a keyed bidirectional exchange, but oh well. I checked on my wife's new car (hers unlocks in a similar way) and there is NO WAY to turn this behavior off.

Anyways, anyone reading this should get a faraday cage for their keys to keep them in when you're at your house. This will prevent people from breaking in the easy way - like in this video. They'll have to resort to the old way of smashing a window. I don't own this one, but see here for a keyfob faraday cage on Amazon. Or this cheaper one as well.

FYI - I have nothing to do with that product, just did a quick Google to find an example.

Edit: According to your cars manual, if you had push button start, this is most certainly how this guy got in. See here for a screenshot of what I'm talking about.

Final Edit: Here is a more detailed explanation (and video) with cheaper DIY ways to prevent this from happening.

u/RAM9999 · 16 pointsr/videos

I use this one ^^

I can put my fob inside, close it, stand directly next to the car door with the bag, and the door will not open.

u/bippity12 · 12 pointsr/london

I'd suggest asking your landlord to install these (or similar). They're used for spaces at our complex successfully

u/pensotroppo · 10 pointsr/LosAngeles

There are cheaper versions out there, but it's only a couple hundos in parts and will save you the $2k a replacement costs.

u/Space_Pecs · 8 pointsr/conspiracy

Buy a Faraday bag, if you're that concerned.

u/2close2see · 7 pointsr/chicago

Not sure, but I'm now tempted to buy one of these, keep it in the cupholder and hand it to whoever tries to carjack me, then bail.

u/CorneliusJenkins · 6 pointsr/Minneapolis

Was just reading a post on /r/Mazda3 about this concept - using some sort of relay attack (I have no clue about the technical term/process here), where folks can relay and/or clone your fob.

Suggestion was to store your key in a Faraday bag to prevent your key from transmitting a signal that can be picked up outside your house.

So, maybe something to look into?

u/Sythus · 6 pointsr/Android

maybe make a custom case that acts as a faraday cage, blocking all signals?

here's a wallet that can also house your phone

u/Kiki_Go_Night_Night · 5 pointsr/priusdwellers

I had no idea this was a thing.
Very interesting.

u/spookyyz · 5 pointsr/LosAngeles

I believe most keyless (passive) entry systems do use a rolling code system. What these devices do is amplify the very low frequency (which is why you have to be so close) request emitting from your car and amplifies it in hopes the key will be in range of the amplified signal. The key fob on the other hand is fairly high frequency and can work at moderate range (think of the range when you actively push an event on the key fob) so if the key fob is in range of this amplified signal it will respond with its answer and the car will behave as if the key was in range.

Here's a more technical breakdown (and accompanying podcast if you'd like):

It is really kind of fascinating. I hope I didn't bungle my explanation of it too much, was going off memory.

Also, to stop said attacks, something like this (a Faraday cage) or many, many others similar to it should be used to house your key when you are in any sort of range of your car.

u/01010110_ · 5 pointsr/videos

You can get them pretty cheap online, though I agree it should come with the car.

u/gusgizmo · 4 pointsr/Cartalk

Spendy but I guess worth it if you have to buy California compliant catalytic converters. If I was somewhere without emission testing Id just put in a cheap cat.

u/ModernVisage · 3 pointsr/answers

Well, I don't know all of the variants used.
I do know some old ones, some standard issue ones, and some advanced ones.

The tags used for pets are around the size of a grain of rice. Doubt you have one of those.
Check your jacket and try to make your room use less consistent.

Audio bugs could be used on your phone by taking control of your microphone. Yes, hidden services could use your location, they track the 'cells' your phone connects to every time you change areas or use it. A competent, well-equipped group could track your phone if it was off or in airplane mode. Take the battery out, or remove the GPS temporarily. Some people go as far as to disconnect their cameras and microphones when not using.
Though, these are tech savvy people. The easiest method is the occasional use and burner.

RFID blocking box
Shop around though, this one has mixed reviews. You also could check out a safe/discrete networking guide.

Someone could install a small brick thing under your car, like what the FBI used to use.
A mechanic or trained eye would most likely notice. They were pathetically clunky in the day, but must be better, now that 'the internet of things' is beginning.

The best source of information, by far in this decade, is obviously a cell.
Most people are dependent on their phones.

The simple solution is to leave the item at home, if you're concerned, or, once again, get a throw away [burner].

I don't want to encourage unnecessary paranoia.

u/Trailman80 · 3 pointsr/mazda3

They are called Signal boosters if you are in an area that has High crime get a Faraday case.

Amazon has them I bought these.

Maybe something like this? And then put it under your car again

u/rockbblues · 3 pointsr/prius

CatClamp Standard Kit there’s a beefier version for twice the price. I didn’t opt for that since i felt it was unnecessary. Just make it as tight as possible because there was a rattle after I first installed it and after tightening it it was significantly less audible.

Some people shrouded the cable that wraps around the car in hose to remove the rattle but I didn’t want to bother with it.

u/dnorm00 · 3 pointsr/boostedscooters

for those concerned with locking it up outside...a few pro tips:

  1. Use a kryptonite New York U lock. Decent amount of choices in that line...I use this one: extra long heavy duty u lock
  2. For extra protection also use a disc brake lock, the one i use is here: Kryptonite Disc Brake Lock
  3. Strap a loud ass alarm to it. I have this one, and can tell you it will deter someone from trying to mess with the above two heavy duty locks...It's absurdly loud, even by busy NYC street standards: absurdly loud, remote lockable alarm
  4. Lock it in areas with consistent street traffic and doubly confirm the structure you are locking to is firmly in place
u/jfourkicks · 2 pointsr/moped

Went with this, and real satisfied with its sensitivity/noise level.

u/iConoClast04 · 2 pointsr/scooters

>What are some ways of preventing theft of the scooter? Does it involve some specialty lock or perhaps being specific about where I park?

I have a [Gorilla Alarm] ( on my scoot but sometimes it goes off unexpectedly and it drains the battery quick if you don't ride your scooter often.

I use to use a U-Lock to attach to my wheel but I've almost rode off a couple of times with it still attached so I hardly use it.

You can get one of [disc brake locks] ( that attaches to your front brake disc and comes with a reminder strap that you attach to the handlebars so you don't ride off with it still attached.

But I highly suggest getting full coverage insurance if you don't have it already in case the scooter does get stolen. Scooters are so light that 2 people could lift it onto the back of a truck and take off. The money you get back from full coverage insurance is surprisingly fair, at least with State Farm.

>I live in Houston. The sun is pretty intense and I love the paint job on my scooter. Is there a way to protect the paint with products or is a simple scooter cover the solution?

This is a great question because if you don't protect the body, it will start fading on you.

You can either use a [paste wax] ( or [liquid wax] ( to give you the best protection. Remember to follow the instructions that come with the wax.

You can use a [spray wax] ( which is the easiest to apply and remove but it doesn't offer the same kind of protection that a paste or liquid wax gives.

Btw, I only used Mother's as an example but most of the brands that you find at your local auto parts store should be fine. Also, make sure to always use a Microfiber towel when doing anything on the scooter's body. Microfiber towels scratch the body the least vs. any other kind of towel.

u/CalZeta · 2 pointsr/motorcycles

If you're looking for a good theft deterrent, get a bigass sticker that says, "It's only a Grom, not an R6!!"


Seriously though, I like my Xena XX-6.

I bought an anti-theft motorcycle alarm, it's triggered by any vibration or movement. I lock it up with some heavy duty chain and an "impenetrable" lock. I live in Chicago and it's worked pretty well for me thus far.

u/johnkiniston · 2 pointsr/scooters

I use RAM Mount hardware for my phone and camera, When I'm not riding the bike it's easy to remove the attachments and leave the bases in place. They also sell locks you can put on the knobs to keep people from operating them.

I'd recommend some saddlebags for shopping, It's no fun wearing a heavy backpack while riding, You can get inexpensive saddle bags that are for large dogs off amazon for pretty cheap

Alarms with pagers are not that expensive actually!

I'd recommend always locking your bike to a large immovable object, 50cc bikes are small and light and easy to pick up and toss in a van or truck if they are untethered.

I have never had my bike messed with or moved in a parking lot, I always make sure to park near the back of the space so drivers see my bike, If I'm shopping and the store has a cart corral that doesn't take up a full spot I'll park my bike in those spots with the carts.

Oh for pants if you can't afford motorcycle specific ones I'd go for a set of 'Firehose' pants, they are more durable than denim.

There was a guy who used to ride with my club that was handicapped and had a handicapped plate on his scooter, he always parked in the reserved spots and never had a problem doing so.

I tried the alarmed disc lock route and hated it. Separate is much better, just a button press and done. Still have a regular disk lock for sketch areas too.

The 2nd link is meant to hook up to your battery. I never noticed any battery drain with it, but I only hooked up the brain/sound. Didn’t want to spend the time to have my lights flash or the kill switch worked in.

u/ImmaPig · 2 pointsr/Volkswagen

You can buy replacement key fob cases, disassemble your key, and put the internals into the new case. The cases can be bought for around $10, but they're never great quality in my experience.

I just replaced the key body on my grandparents chevy equinox keys last week. The buttons literally wore off the keys and they couldn't reach the unlock button on the internal circuit board. The replacement parts holes for the pins of the flip key were off just enough that the flip key wouldn't lock open or closed. It took an hour of filing the pins down and drilling new holes in the replacement parts for the key to work properly.

It can be done, but it's a huge pain in the dick.

You could always cover up the worn key with a classy case like this.

Here's a case [Amazon] for the Mk6 Jetta. Before you go buying, I recommend watching a couple videos on how to take your key apart and actually try it so you can compare your internals to the case you’re buying. Good luck!

u/Bezzle59 · 2 pointsr/CarAV

DEI makes a passive keyless entry system, themselves (as does Compustar w/ EZ-GO, maybe more), called the PKE. Like the other user was saying, DEI units can be remotely activated with the activation input. For example, hitting the lock button 3x to remote start (could also be done from the door, itself).

u/CatsAreGods · 2 pointsr/prius

I just got one of these and it blocks active signals as well:

u/tunersharkbitten · 2 pointsr/Toyota

line a cardboard box with thick aluminum foil. that is a very basic faraday cage.

personally i have a cheap faraday bag i got off amazon. there have been a couple people in my neighborhood that have gotten their cars stolen via repeater spoofing. didnt want MY brand new car to go the same route.

u/seatrip · 2 pointsr/Hookers

Get one of these and put your phone in it. Works like a charm.

u/vapeducator · 2 pointsr/scooters

I have some of these thick steel cable locks. You can hook them together as long as you wish, but 2 will usually work fine for a scooter. Maybe there's something similar in the BENELUX area.

I have purchased motorcycle alarms with 2-way remote like this one. The alarm notifies you on the pager with the sensor that was triggered.

I've also purchased GPS trackers like this one. It uses a GSM sim card to notify you by text message if the tracker has left an area that you define. It can also text you if it travels faster than a defined speed. It doesn't only rely on GPS for tracking. It also uses GSM/GRPS to triangulate a position and give you an actual street address. You can call or text the device to engage constant tracking with updates every few seconds or minutes.

One of my scooters has a remote start with engine kill.

There are also alarms like this one that have a proximity sensor that triggers an audible warning if anyone approaches the scooter, besides sending notification to the remote control pager. I haven't purchased this one.

u/twowrist · 2 pointsr/CX5

This type of fob cover makes it harder to push the button accidentally, but not impossible.

This pouch successfully shields the fob from activating the lock. I haven’t tried pushing any of the buttons on the fob while it’s inside this pouch.

OP, are you in Albany Park/Andersonville/Ravenswood/Lincoln Square are? This shit is happening a lot up here. I would seriously consider getting a CatClamp after the you get it replaced and have some extra scratch. It won't stop them or anyone who's very determined, but it's enough for them to simply move to a different car after one look at it. If you park in the same area, these guys might come back, spot your car, and do it again. It happens.

I've been using a Xena XX-14 for the couple of months that I've owned my bike, and I'm pretty happy with it. It will definitely go off if the bike is bumped, and when it does, it's loud.

great question as I have been wondering the same thing. For my 2015 I've been hovering over this one:

u/DRHOY · 1 pointr/videos

A solution could be to replace - or redund - the ignition with a dead man's switch and proximity switch. To enable the vehicle to be turned on and to maintain electrical connections, one must be within proximity and in possession of the proximity fob. To turn on the vehicle and maintain electrical connections, one must place the magnetic "key" on the magnetic "ignition". If the driver is removed from the vehicle, the key will also be removed (as it is tethered to the driver), and the fob will also be removed (as it is on the driver's person). Both items are necessary to maintain electrical function of the vehicle.

u/pbae · 1 pointr/scooters

The padlock would definitely stop your scooter from rolling but one day, you might forget it's on there and try to take off which would cause some damage.

They sell [disc brake locks] ( that come with a coiled strap that you attach to your handlebars after attaching the lock to your disc. The strap is a reminder that you have the disc brake attached before you try and take off.

I just got and installed one of [these] (

Although it's just an alarm without an ignition kill, it is pretty loud and it only took me about an hour to install.

This alarm also has the option of adding a 2-way remote which supposedly works for up to a 1/2 mile away and it notifies you if your alarm is going off.

I highly recommend this alarm if you could spare $100 bucks.

u/MasterK999 · 1 pointr/cars

Get a Farady bag. It will also fully prevent any range extending car theft attacks.

Purchase and install one of these.

You may want to get your landlords permission if you aren’t a “beg for forgiveness rather than ask permission” person. Agree to provide the landlord with a copy of the key if you do.

You'd need to keep the key in one of these to prevent this sort of attack.

A PIN to drive would prevent them from driving away, but not from getting into the car to steal anything inside.

u/00worms00 · 1 pointr/scooters

I reccomend this

as well as a lojack gps type thing. These will be more of a deterrent/save your ass in theft wheres any chain no matter how big a thief will be able to get through it.

You park a scooter on the city street at night? yikes. The way a thief thinks, if they know that 2500 dollars is just sitting out there on the street every night they will be willing to plan for weeks and invest hundreds to pull off the job. Think about it. people commit armed robbery or B&E with less of a guarantee of profit.

good thing getting theft/vandalism insurance. They gave me a 50 dollar discount off of mine for adding the lojack thingy as well as added it to the total cost of the scooter in claim.

Above is the wiring diagram I was able to find for my scooter (a buddy 50) and this is the alarm system I purchased: BlueFire Motorcycle Security Kit Alarm System Anti-Hijacking Cutting Off Remote Engine Start Arming Disarming

I want to attempt to install it this evening, without ruining my scooter/not being able to use my scooter. I use it to get to and from work and it's not exactly a walkable distance, 12 miles, so I need the scooter to be functional. I purchased the system a few months ago because I was a bit paranoid that someone was attempting to get my grip lock off my bike as mirrors were somehow getting loosened and would move when I drove. Well this morning I'm pretty sure my grip lock bit the dust and I will have no other way to secure my scooter. Any advice, hints, tips, tricks or good ideas on installing it for a newb?
