Here is the procedure for resetting, let me no if this does not work.

Insert the ignition key with remote fob into the ignition switch and turn to position 2 (ignition on; minimum 2 seconds).

Remove key, press the lock button and hold depressed, while simultaneously pressing and releasing the unlock button 5 times within 5 seconds.

Wait two seconds, then press the lock or unlock button once and release. The remote keyless entry functions should now be synchronized.

it does not work except for once. If I go thru this which I did before I then can use the lock or the unlock once only and it works. This is what I referred to above as the re-syncing instructions. S this is not an answer that works
