Volkswagen Jetta Security System



  • I have a 2006 gas Jetta. The remote key entry does not work. Last night, I opened the driver-side door with the key, then tried to open the trunk prior to unlocking all doors and the security alarm went off. I could not stop the alarm and had to close the driver-side door and trunk to get it to shut off. However, now I'm unable to start the car without the security system going off.
    Does anyone know what I should do? Do I need to re-set the security system somehow?

    I left my lights on on my 2002 Jetta TDI about a month ago and had to get jumped off. The idiot who jumped my car off reversed the cable ends and made a big spark. When he put them on the correct way my car started right up but every since then, periodically my horn beeps continuously and my lights flash too. After turning the key in the lock a few times it would stop but now my car won't start. The radio, AC, and lights still come on. But then there's the flashing and beeping still? I had the battery tested and its fine. When I remove fuse 14 (as instructed by a certified mechanic ) the flashing and beeping stops. Anybody know what is REALLY going on here! I was also told it could be the control module... if not the whole thing, the "part" that connects with the starter. Please help!! Oh and I forgot to mention, my inside locks don't work properly either. Sometimes the main lock will lock ALL the doors and sometimes it won't. This also holds true for the trunk release. The keyless entry won't work now either.
  • Hey All,

    Here's my problem in short: If the car doesn't arm itself (i.e. the chirp/beep doesn't occur when you lock the doors, though the doors are locked) the next time I attempt to start my car, it will work for a bit (about 2 city blocks) and then shut down. It will not start again, and only when the car decides its good and ready to "arm" itself (i.e the chirp happens) and I wait 10 minutes, does the car start, no issues, and everything is A-OK.

    Information about my car:
    2000 Volkswagen Jetta, probably the 2000.5 version, its the newer style body. The driver side door was knocked into by a ConEd van a while back, but before I owned the car. The doors close normally, and everything works save for a whistle when driving on the highway with the window down.

    I've read about it being door sensors, but is there anything you know to help "reset" the alarm so it will arm itself again? Any other possible causes? Thank you for all your help!

    PS if this is in the wrong forum I apologize, this is my first post. Thank you once again!
  • I have a 2008 Jetta, when I lock my doors with the key the anti theft horn alert no longer sounds. Is this a fuse or sensor? I was told it is housed in the trunck, is it a simple fix?

    If one of the door sensors was misbehaving, I would expect the 'door open' display on the dashboard would tell you. Since you did not mention any lights on the dashboard, I would have to assume the doors are not the issue.

    Do not forget that both the HOOD and the TRUNK also have sensors. If either of these are 'sensed' as not being closed, then the alarm will not arm.

    Also, I believe there is a 'trunk open' lite on the dashboard and it is not lit.... so perhaps the only thing left you need to check is the HOOD sensor.
  • Hey!

    Thank you for the response. I actually got the car fixed, turns out it was something called the "comfort control module" when that breaks, the car didn't think it was armed, and then wouldn't allow me to turn the car on because the system was fooled into thinking someone was stealing the car!

    Glad to hear you got it squared-away....

    BTW: The "Comfort Control Module" in my Jetta is also known as the "Seat Heaters" - LOL
  • Behind your light toggle switch there is the security control module. You can bypass the ignition cutoff by bridging the wires that control the shut off for your starter. There are two wires look- up the electrical diagram for this module and you should be good to go. I want to say bridge the ignition wire going in with the starter kill switch wire. By bypassing the module your doors and trunk security will still be active. I just went through that with my 97. I was going to put a new module in but it is no longer made.

    Some VWs of that vintage fell victim to the "coolant migration problem". The worst-cast scheario was a total electrical failure. Lets hope you did not purchase a VW which was affected by this problem.

    As for the alarm-system causing your issues - It is possible that when you bought it, you did not get the proper keyfob that controls the alarm. It is also possible that some of the microSwitches inside the doors are flakey. this can really confuse the alarm-system (ie... door is sensed as OPEN and CLOSED at the same time, or LOCKED and UNLOCKED at the same time)

    Personally, anytime I negotiate the purchase of a used vehicle, I INSIST that all the proper keyfobs are made available or no-deal! Most used-car dealers will agree to this demand to close a deal.
  • The car key was missing the whole button section he just gave me the key it look like something was missing i asked about it and he said it has alarm but i didnt know if i really needed it and if the alarm work it has a red light flashing but no sound or anything my car dont unlock or lock with the key so if i lock it on the passengers side and try to open it with my key it wont do nothing but the car lot guy said it was the alarm making it not work or start i just dont know?
  • I know you posted this a year ago but I just got a 2004 Jetta and my anti theft doesn't beep/chirp either when I lock my car with the fob, I was just wondering if you ever got it to work and if so how? Thanks!!
  • bpeeblesbpeebles Posts: 4,085
    Dont forget that ALL the doors plus the hood and trunk must be closed for the alarm to 'arm'

    Also be aware that it is not uncommon for the microswitches in the doors to become troublesome. This can send implausible signals to the computer. (Door open and closed at same time.... etc.) The computer responds by simply not arming the alarm system.

    Connecting laptop to the computer-port can diagnose the specific problem.

    I have 2011 Jetta SEL with keyless start. On four occasions car has not recognized key and would not start. Dealer in San Antonio (Freedom VW) unable to repair system. VW tech support could offer repair fix. Taking car for second opinion. Antone else experience this problem?
