I've got an idea of how to get my problem solved, I just want the alarm to never go on in the first place. To clarify my problem, I need to be able to lock the doors...but the key fob is not working and I'm not intrested in paying that kind of money to fix. When I lock with the key, the alarm always works and arms the car, however when I unlock the car with the key, it almost never disarms causing the alarm to go off when the car is started or other doors are opened.
 
The disarm in the trunk works. If I use the key back there to open the trunk it will disarm the alarm, then I take the trunk closed sensor away from the trunk and leave it open, the security should never arm again because it will always think the trunk is open. Is there any reason that wouldn't work?

Dont forget there is also a "Hood Opened" sensor too.
 
Also, beware that if you do try to "fool" the security system in the way you are describing, you may end up with a perminant "door opened" indicator on the dashboard.
 
Be VERY careful that you do not mess with the "immobilizer" circuits. The alarm may be annoying... but the "immobolizer" will simply kill the engine and you will be stranded. The alarm and the immobilizer are both part of the security system and they may be tied together in some ways.
 
If you really are considering messin with trying to "bypass" the alarm... why not go ahead and just fix the microswitches in the door and be done with it?
 
There are several step-by-step procedures on the internet showing how to replace the door switch microswitchsx ($3 with Radio Shack part)

bpeebles,
Thanks for the advice about the imobilizer. I tried my idea last night with the hood actually. It seemed to work for about 5 min, so I buttoned up the door rag and 2 min later I went to move the car and it armed again.
 
I read the switch replacement post, but as with the hood sensor, I find myself asking... if there's just one plug that gets both the open and closed signal, why don't I just unplug it and disarm with the trunk to never have to mess with this thing again. It sounds like a major PITA to get the door pannel off, then get the lock assembly drilled out from the rivvets, dremmel tools....I just hate security and if I can get it to never come on, I'd be happier.
 
Also, if I were to know where the keyless entry module is for the car, and it's not a $500 part, I MIGHT be interested in replacing that as it's probably not ordeal this is and I'd get my keyless and security problem fixed as I'd be able to dissarm with the keyless.
 
I've asked around and gotten 3 different answsers on this, where is the alarm horn on this car? Its a 2000 Jetta base model, a GL I believe. If I were to just unplug the horn and ignore the alarm altogether, would that trigger the imobilzer? I've heard that 2000's don't have an imboilizer, is that true, and is there a way I can verify that on my car?
 
Thanks to everyone for the advice!
Wes

I understand that the antenna for the remote is behind the dashboard. It follows that the reciever circuit must be nearby.
  
I beleive the "alarm horn" is one-in-the-same as the normal horn.
 
Not certain about the 2000, but my daughters 2001 DEFINATELY has an immobelizer. She has complained about the engine starting and the immedeatly shutting down. (this is how the immobelizer works)
 
When I hooked up my VagCom and ran diagnostics... the onboard computer reported that the immobelizer had been "triggered" reciently.

#22 of 36 2006 Jetta security system is locked, please help! by keenanlayton

Aug 10, 2009 (5:30 pm)

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?

#23 of 36 Idiot reversed the cable ends when jumping off my 2002 Jetta!!! by tdiva

Jul 27, 2010 (10:44 pm)

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.

#24 of 36 Jetta Alarm System Won't Arm Itself by crimsonashes

Aug 09, 2010 (11:54 am)

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!

#25 of 36 2008 Jetta Anti theft Alert does not sound when locked with key by labsadler

Jan 21, 2011 (12:13 pm)

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.
