The spare on my lag doesn't unlock the car, but it does start it if you put it in the ignition and start it. So I thought, microswitch fallen off.
Very carefully cut the card open, however the microswitch is firmly attached.
I did a bit of testing and found out if you bridge the two contacts on the lock button (Which works anyway) the red LED will light, however if i bridge the contacts on the unlock button I get no red light. This would seem to suggest that its not the microswitch at fault?
Had exactly that problem on my key. Turned out to be one of the pins on the IC half way down the card. Thing is you couldn't see that the joint had broken.
Re-flowed the joints on the IC now good as new.
