    key remote not working on 996 C4

    I just had the same issue with my 996 turbo cab and did all the steps that others had done. It turned out from 2 different Porsche mechanics that the problems was that the "immobilzer" that interacts with the antenna, was bad. The keys were sending out a signal but the car wasn't receiving the signal.  This is not a cheap fix by any means.  My understanding is they are ordering the part which could be upwards of $1700 without labor.  Also, they would then need to reprogram the two fobs.  I was told by both mechanics that at some point, if I did not do this, the car would not recognize the key and the car would not start.  Oh the joys of owning older cars.

    I'm having trouble with my key remote operating my locks on my 1999, 996 C4. I've searched this topic, but cannot find a solution that works so I am hoping for some helpful ideas.

    My remote just stopped working one day and it hasn't worked since. I have tried the following:

    -installed new battery. LED works, but doesn't operate door locks.

    -reversed battery polarity. Still didn't work

    -pressed button while unlocking door. Nothing.

    -unlocked door manually, then pressed remote button. No luck.

    -turned on ignition, turned off and immediately tried using remote. Nada.

    I bought a Durametric tester and I get alarm fault codes 33 (faulty compartment monitoring sensor) and 42 (incorrect key or transponder). Every time I test I get these and only these fault codes. Also, the frequency of these codes is always 1.

    My key works fine to manually lock and unlock my doors. It also starts the car. My alarm also seems to be working fine. I just want to be lazy and operate my door locks with my remote button. I am at my wit's end trying to make my remote key work again. I was thinking about checking the fuse in the alarm system under my seat, but I don't want to go to the trouble of removing my seat if that's not a possible fix.

    Thank you in advance for your help and suggestions. This is my first post and I really appreciate your help.
