Keyless Entry Transmitter: Testing and Inspection
The key fob transmitter code will go out of synchronization if any button is press more than 250 times outside the range of the receiver which is inside of the BCM. In other words the transmitter will not work. To synchronize the code of a particular key fob transmitter with the receiver, press and hold the lock button then the deck lid button simultaneously for at lease 5 seconds. Then wait until the doors unlock indicating that the code has been synchronized. This may take as long as 6 minutes. This is for a key fob transmitter that has been previously programed to this vehicle only.
