Key Fob Lock Not Working
Okay 996 experts....
Key fob is no longer working either the front trunk nor door locks. Battery is relatively new and no changes to routine with my car. What is the likely culprit? Oh and of course the alarm is no longer triggered by the key either.

Try this: Take the battery out of the key fob and reinstall it upside down for about 15 seconds. Remove the battery and install it correctly. See if that "jump starts" the fob.
DO you have a second key fob? Does that one work?

So I have not used mine in a couple months and should have checked it before trying this rediculous "trick" but after I did it the thing seems to work much better than I remember....
but why.... with the battery upside down both FOB connectors contact the same polarity of the battery...that should have no effect at all...
(though I cannot discount that my FOB seems to be at least working when I thought it was dead)

You can discharge the circuit by simple removing the battery for a few minutes.
I would not recommend inserting the battery backwards, unless specified
by the manufacturer (I never saw a DC circuit that requires that by the manufacturer).
On the other hand, in some instances when inserting the battery backwards,
you may have a fast battery discharge, and/or a hot little battery followed by a little explosion!

FWIW:
Re-synchronisation:
Switch on ignition with key and valid transponder.
ˇ Switch off ignition.
ˇ Remove ignition key from steering lock.
ˇ Operate transmitter within 6 seconds after the key has been removed.
If the LED on the hand−held transmitter stays dark when the transmitter is operated, this is an indication of either an empty battery or a faulty hand−held transmitter.
Radio transmission is OK if the LED on the transmitter flashes when the transmitter is operated and the alarm readiness lamp on the dashboard flashes rapidly.
