• Extra Remote Keyless Entry = $6.54
  
  Notes:
  
  The Z keychain isn't sharp (corners) at all; I don't even notice it in my pocket.
  
  The red remote is just a plastic shell and rubber buttons. You need to either take the circuit board and battery out of a current key fob, which is extremely easy, or order an extra remote (3rd link) to use the internals from it. Reprogramming a new keyless remote is even easier than swapping the "guts" out, and it comes with instructions. A quick Google search will also reveal said instructions.
  
  Even though the extra remote says "2003-2006," it will work with 2007. In my case, the car only came with one remote. This was a pretty cheap (and unique) option for an extra. It works perfectly, just like the original key fob.
  
  Look around on Amazon for extra colors. I have seen blue and red, but not sure about white or any others.
