#17 of 22 Re: 2000 Jetta GL Security [bpeebles] by springob Oct 30, 2008 (5:06 am)
Replying to: bpeebles (Oct 29, 2008 6:20 pm) 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? Replies to this message: bpeebles (Oct 30, 2008 5:53 pm) springob (Oct 31, 2008 3:52 am) bpeebles (Oct 31, 2008 3:05 pm)

Replying to: springob (Oct 30, 2008 5:06 am) 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)   http://forums.tdiclub.com/showthread.php?t=77648   Removing door panel http://forums.vwvortex.com/zerothread?id=1015107   Removing front door parts (from thread above) http://forums.vwvortex.com/zerothread?id=961163 Replies to this message: springob (Oct 31, 2008 3:52 am) bpeebles (Oct 31, 2008 3:05 pm)

Replying to: bpeebles (Oct 30, 2008 5:53 pm) 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!

Replying to: springob (Oct 31, 2008 3:52 am) 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 22 2006 Jetta security system is locked, please help! by keenanlayton Aug 10, 2009 (4:30 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?
