How do u turn off the stock alarm? Mines worked today and now I can't turn it off and now the battrey is dying. Someone help me out need to get to school.

 

My alarm went off for the first time since I bought it 2 years ago (88 S4 Vert) last week. I figure someone bumped the car. I put the key in the doorlock and opened it and the alarm stopped. That's all I know, the alarm light comes on when I lock the car and goes out after a couple of minutes.

It comes on when I open the door to get in then It would turn off when I put the key in. But this time it didn't work and keeped flashing. I opened up the CPU to fix my horn. Now I got this going on WTF.

 

I can only open the door with the key. I can't lock it from the door with the key.

 

s4 or s5? (i have no idea if there are any differences in the factory alarm system between the two)

you could just not arm the alarm. but im a bit confused as to exactly what the problem is.

maybe something happened when you fixed the cpu for the horn?

 

Nah I just re soilder the stuff. I arm it by locking the doors by pressing down the lock on the handle. Then it comes on when I un lock the car. The problem is I can't dis arm it.

 

Everything you ever wanted to know about the operation of the Factory Alarm System (S5 models at least).

 

I can't seem to turn it off even if I stick the key in the Ignition and turn? Help! The alaram kills the starter.

 

No don't try to start the car. I put an S4 door on my S5. It goes off sometimes because the electronics in the door are different. So I usually run to the pass side door + use the key to open it from there. Try locking everything then unlocking a different door. Or try locking then opening the hatch with the key. You can always unhook your battery they connect it again.

 

My car is a s4. I can only use the key on the driver door. All other lock the key won't even turn.

 

In the first .jpg I posted above, read top right paragraph.

Also read the bold letters in the bottom left paragraph of the last .jpg attached.

 

I tryed that when it was going off. And still nothing. Can it be the CPU for that and resoilder it?

 

check out the contacts on the door lock switch and clean them up.. then the off switch is located on the door locks themselves if i recall.

Im curious how effective the OE alarm is against say a drilled out lock?

 

What do u mean a drill out lock? The oem alarm miles the starter so it's a kill switch when it's on.

 

I ended up disabling mine completely, it had no rhyme or reason to it's behavior. Unplug the control unit located under the glove compartment if all else fails. Just don't leave anything valuable in your car (not that any alarm is much of a deterrent to a desperate thief.)

 

Yeah I was just thinking about taking it out.
