Key fob stopped working, not the usual things?

My '99 996 Tip Cab has been having central locking issues. Initially it would beep when locking/unlocking, but I tracked that down to the microswitch in the passenger door and fixed that. Now, just a couple of weeks later, the key fob stopped working suddenly. Normally I'd expect reduced range with a battery issue or unreliable opening if it was a contact problem, but I saw none of those symptoms. To be sure I switched to a new battery and checked that the key fob board all looks good. Still it is completely dead.

I checked the car with my Durametric and got the following codes. I assume that may have come from when my microswitch was going. If I try to clear the codes, they come back with the same counts on the next restart.

I don't have another key fob to try it, so apart from getting new key fobs and paying the dealer $$$, I'm stuck for a next step.

Could there be some other problem that would cause the alarm to chirp once and not open or close the car from the key fob???

Fault code 21

W lead (DME - immobilizer), open circuit

- Short circuit to ground/open circuit in the communication lead between the alarm system control module and the DME control module
Fault code 33
Passenger compartment: monitoring sensor faulty
Possible cause of fault
- Passenger compartment monitoring faulty
Fault code 47
Central locking synchronization
Possible cause of fault
- Short circuit to ground/open circuit between alarm system control module and door locks
- Door lock faulty
Fault code 60
Central locking limit position 'Locked' not reached
Possible cause of fault
- Central locking switch faulty
- Short circuit to ground/open circuit in wiring between the alarm system control module, central locking switch or door locks
- Driver's/passenger's door lock faulty

Fault code 61
Central locking limit position· Unlocked not reached
Possible cause of fault
- Incorrect country coding

The most common fault 60 and fault 61 faults we have seen are mechanical latch/lock problems in the door latch mechanism.
Fix that then clear the codes and see if any come back (perhaps the Passenger compartment: monitoring sensor fault).

On a related topic, I replaced the central locking module under the driver's seat in my 2000 Cab4. I did not have the key codes to enter into locking system so I can only open the doors manually. Is there anyway to discover the key codes? Dealer did not know of a way.

Thanks,

Maryland

If you do not have the 40 digit codes that came with your key(s) then you will never be able to program them in - you would need to buy new keys.
