    Thread: 2000 Passat Alarm Doesn't disarm with key in door

      You can lock and unlock the drivers door. but some times it wont lock or lock other doors in car and wont disable the alarm.
      I have pulled the carpet the comfort module is dry and clean.
      It has a duralast battery (700cca) And I suspect its the battery causing the problem. On the battery charger it locks and unlocks every time for me.

      any help would be greatly appriciated!!

      from what i understand the comfort module controls the door locks and windows

      in a ford it would be called a GEM module

      well if its not the module its the central lock unit causing the problem

      with a vag com you can change things like if the alarm blinks lights when you arm disam the alarm or stop if from auto locking the doors. thats all

      if i could stop the auto lock i think that would solve the problem ....

      I went thru this around '01-'02 w/ my '98. Your driver's door (or other door depending on symptoms) lock mechanism needs repair or replacement (mine had the cracked solder joint):

      ok i just did the job on this and its not that hard i think the lock assembly is like 200-300 new from vw

      you need a special 8m tool (looks like a torx but has 2-3 times the teeth and they are finer) for the lock assembly to unbolt it from the door

      pull the door panel there is a backing plate to the inner handle/ switch panel that pops off. Also there are two torx screws on the bottom of the door. the rest of the retainers should pop off
      then pull out the switch panel and unplug it
      pop the door panel off and lift up ( they tend to stick at the top)
      Disconect the inner door release cable
      Unplug ALL electrical connectors including speaker, mirror (execpt power window connector).
      (i leave the little light on the bottom of the panel for last)
      you need to lower the window till the window bolts are visible through the two rubber plugs in the door ( plug the window door lock switch back in.)
      roll window down.
      unbolt window
      pull up and out through the outside of the door
      unplug window/lock switch
      unplug the window motor (youll notice there should be a littleslider in the plug. Slide down as far as itll go then pull the plug off
      A t20 torx bit willl be needed to back off the lock screw (inside the plug cover on the latch side of the door) back off the screw until the lock comes out keep trying the lock and unscrewing the t20 torx until the lock cylinder pops out.
      DO NOT blindly back it off or the ring that holds the lock cylinder will fall off and youll need to pull the inner door handle off to put it back on AND find a magnet to pull the ring out of the door (there is a metal brace it likes to hide behind if it falls off)
      now that the lock cylinder is out youll see a cable in the handle pop the cable off the door handle.

      pull all the 10mm bolts holding the inner door
      ok unbolt the door lock latch assemble (AKA central lock unit)
      there are two 8mxm8 (or somthing like that bolts)
      Take all 10 mm bolts off the large silver door plate (this plate holds the door lock, speaker, window motor and window track.
      the window track hanges a little lower that the plate so pull up and towards the car.
      ok now you need to pull the last plug on the "central lock cylinder" pop the rubber gromet and the wires out of the plate.
      take this assembly to a work bench
      the locking unit youll see is riveted on to a bracket, but is also bolted to the door when installed...
      NOTE: the black plastic brace on this assembly that holds on the central lock unit is only there to hold everythinng in place durring instalation.
      if you drill this rivet expect the black plastic brace to melt
      suggest you buy this brace from VW or do this ..
      drill hole in the brace and use a large heavy ziptie and go through the hole of the new locking unit and through the brace.
      before ataching the new locking unit atach all cables and lock knob.
      remeber to guide the lock knob throught he hold in the door plate before attaching the locking unit to the plastic brace.
      ok reverse everything
      get the plate in the door DO NOT BOLT IT IN YET
      plug central lock unit electrical plug back in.
      put door locking unit bolts back in the door
      Reach your hand in carfully inside the door and put the cable back in the lock cylinder hole and push it into the handle track (from the front)
      put lock in gently
      tighten lock retaining ring bolt (above the lock latch bolts in the door)
      TEST and make sure every thing works
      use a screw driver to close the door latch
      (this will alow you to lock the drivers door)
      you have to plug in the window motor power plug to operate locks
      OK everything work? the rest is a snap
      bolt the plate on
      Put in the window, bolt it down.
      plug all electrical connectors in.
      put door panel back on
      put in the window/ lock switch
      put on the lockswitch back plate.
      hope this helps some one

      For anyone needing more info on the tool, it's called a Triple Square (or TSQ). The only place I found it locally at the time was Autozone. A set of 4 bits was $12.

      The problem may be a defective door lock mechanism, maybe recognition of the physical key. I discovered this problem when I lost my remote and had to buy a new key. It came from Germany to my mechanic in about 3 days...but the alarm wouldn't disable. I'd also had this problem with my 2000 Jetta...
      However, I have no problems with my remote key (just found it again!) So...if a $250 remote key (ouch!) is cheaper than repairing the lock cylinder...

      btw nice site and great emoticons!

      Back from the dead!!!

      But seriously, this is good info - there have been at least 5 threads on door lock modules in the past couple weeks.

      Here's what worked on mine. the alarm goes of by itself, the car locks and unlocks by itslelf and doesn't start, so the lock assembly seems to be kaputt. BUT THE OTHER LOCK ( IN THE TRUNK) IS OK, WHILE THE DR LOCK HAS A PROBLEM, IF YOU UNLOCK WITH THE KEY A STILL HEALTHY TRUNK LOCK THE ALARM DEACTIVATES. GL!
      It is a time for a new lock for a 11 year old car.
