we discussed it here some months back. I have sorta given up.
Its not the keys - kinda obvious from BOTH going bad, but i also checked and went through the re-pairing dance. Twice.
Mine occurred after the car sat for the winter while i rebuilt, well, nearly everything :-) I can imagine that something was dislodged - e.g.: n antenna wire, in all the work. I dont knwo exactly where it is or how its connected, but when i get the ambition that will be one of my first things to check.
Why? Logic works. Lights flash and things chirp. Lock works mechanically. Not key fobs themselves. Appears not to be pairing.
SO it must be something between the locking logic and the key - the transmitter/receiver, its connection, or something subtle.
Good luck, and if you find out, please tell me/us.
