I just got my 2000 P38 back from the shop (they replaced the intake gasket). It appears that they disconnected the battery (as they should) to do the repair, because the clock was not telling the right time. (but the windows were re-synced) and now, my key fob wont lock or unlock the vehicle. I use the key, but I don't see the red 'armed' light on the dash activated either. When I use the fob, it's LED illuminates (the batteries are pretty new). I tried holding down the lock button and also the unlock button while I manually locked and unlocked the car, but still no joy. Does anyone have an idea what this might be, or what I am doing wrong?
