Looking for some guidance here. Have a 1999.5 cabrio with a temperamental keyless entry alarm system. I just spend $90 at the shop for them to tell me that the unit either needs to be replaced or there is a wire problem. I can find the units on ebay for around $25. So I'm not really concerned about the price. Here is my question for you: The system worked fine until the fuse panel came down from the dash. When I replaced it back in the holder and checked to make sure all fuses were making contact the keyless entry system started to malfunction. I can lock the doors with the key. The alarm sets for about 30 seconds and then faults out. The doors remain locked. If I try to lock the doors with the remote, the light flashes showing its set, but it doesn't lock the doors. I can unlock and pop the trunk with the remote though. When I key lock the doors it arms, resets without the alarm on, but after it faults off it will not let me pop the locks or the trunk with the remote. Perhaps someone out there has more knowledge than my shop did and will have a simple solution for me. I am hopeful it is just the controller. Any help would be greatly appreciated. Thanks!

Key in door, the doors lock, it try's to set the alarm and then it faults. Doors stay locked. I can set the alarm, but it always faults to off. The light on the drivers door only will flash 1 time for what it usually would flash 10 or so. As for the remote I will wait and see what you have to say about the key.

There is a part to bypass the alarm altogether, for like 3$ at the dealer, you plug it into the wire that goes to the alarm. The alarm is a silver box with two plugs going into it, right above the fusebox, so it's possible you damaged or pulled some wires out.

Did you find out what the problem was with the alarm?

What model car?
What problems are you having?

the problem, the alarm seems to want to go off when it wants, but forgets that it is only supposed to go off for 1min...

4 hours and a noise violation later, i was out of town, its for for it to go, i has also gone off once while i was driving. neat hun?

does anybody know the part number, my VW dealer stared at me blankly when i asked for such a device.

thanks

its a 1993 golf, aftermarket stereo head unit.

I agree with the trigger, retrigger thing.

the hood switch is a std plunger style located by the coolant resivoir.

the alarm operates as normal. but is unrelible as previously stated; im not a big fan of campus security and the city police as previously stated.

but honestly is a beat 13y/o VW, if this bypass is available i would rather just to that at this point, rather than have another incident like this.

if this part does exist and some body has a part number for it i would really rather just to that; its just an old car.

there was a previous incident that was similar but the horn would remain on constantly, and would not strobe like its supposed to, the tail lites would flicker randomly.

i have no doubt that the problem could be caused by a faulty switch or the alarm module its self. im a student i don't have time to start pulling switches apart or removing door pannels, i will take a patch at this point. the car has no central lock, or any of the fancy locking mechanisms.

thanks for any help.
(does anybody wanna share that part number?)

Couldn't resist a cheap VW part!

So I went to test fit (in case of future alarm failure) and found the plug fittings to not match bypass plug (2 pics attached above).

I'm pretty sure I have the correct module out since the car will not start, alarm does not set and if I bridge 2 terminals on 'harness side' I can crank.

93 Golf 2.0

I'll see if it has a silver box.

I bypassed the alarm once, a while back though.
All I did was unplug both alarm harnesses and used a large jumper wire from WFS1 to WFS2.
But the jumper went inside the 6 pin alarm harness.
Not into the alarm side.
