Default Central locking system randomly locks and unlocks doors - 1999 A4 Audi

Hi,

I have several problems with the central locking system and alarm of
this unmodified 1999 Audi A4, which may or may not be related:

1. The central locking system will lock and unlock doors at random.
This can happen when the car is moving, parked, or unattended parked!

2. A problem linked to the locking system occured yesterday at a gas
station. I would unlock the doors, and the doors would immediately
lock again (including the gas door) - so that I could not fill up the
car. The problem was solved by asking someone to stand by the gas
door and quickly opening it while I was pushing on the unlock button
on the driver side door.

3. The remote control keys don't work, and I am unsuccessful at
attempting to reprogram them.

4. The alarm system blinking light does not light over 90% of the time
(it has lit only once recently).


5. The trunk lights don't work when you open the trunk. I add this
info in case the problems above are caused by a malfunctioning switch
detecting the status of the trunk closure.

Has anybody experienced these problems... What should I look at or
test to troubleshoot the problem and fix it? I only have a voltmeter
for now...

Cheers!

Take the key fobs away from the general vicinity of the car (100 ft or so)
and, one at a time, bring them to the car and work the locks. Does it do it
with one and not the other? If so, you may have a bad switch on the key fob
that is causing the doors to lock.
