There's is a way to program the keys, but youd probably have to buy the key itself from the dealer (bcuz it has the chip in it)
and to program you will require (2) keys that have been previously programmed...( 2 Master Keys, 1 Valet )
Here are the instructions (credit to whoever found it bcuz i dont remember where)
1. Insert an already programmed key turn to the ON position (dont start car) observe the security light come on and then go off
2. Once the light goes off remove key and insert another programmed key (different from the first) again turn to ON position again observe the security light come on and then off Remove Key
3. Insert the new UNPROGRAMMED key and turn to the ON position and observe the same as above after which this 3rd key will be programmed, once the light goes off turn the key to start the engine. Engine Starts Programming Successful..
Try to do all of this fairly quickly within 10 seconds..
Thats should save you the $150..
PLease send $50 to P.O Box 123456 Thx You..
