I'm of little help, my buddy showed me how to do this a long time ago. I think you have to stick it in the door and hold it in the lock position or something.

It should be in the owners manual. Just did mine and if I remeber correctly, press the unlock button, put the key in the ignition and turn it all the way forward without starting the engine, take the key out of the ignition and press the unlock button again.

How to reprogram the switchblade key

--------------------------------------------------------------------------------

The following instructions are to reprogram your switchblade key fob.

1. Take a spare key and insert it into the ignition. Turn it one click forward.

2. Roll down your window just in case. Step outside the car, and lock the car with a second key.

3. With your second key fob press the unlock button. The lights should flash.

4. Now lock the car with the key fob, and then unlock it.

5. Remove the key from the lock and the key from the ignition, and try it's function.
