Well thats if you have an alarm, I accidentally got my key to close to my sub when i was installing it, and well, long story short, i had to use my fiances key for my car, to make my key work again. FYI, you can program the new key really easy, you use the working key, to turn the ignition on, then turn it off, and within a very specific time period put in the new key and turn it to the on position, and viola, new key. The fun part is doing it within the time period.
