Stupid Alarm....help!

I don't know if this is the right place to ask, but here it goes. I wake up super early for my job and I'm guessing my WJ just wants to make sure I'm awake, but the alarm will go off randomly when I am opening the door. There is no key fob for the alarm, and I am using the original key to unlock the door, so I don't get why it's going off, it sure does piss off the neighbors though. Is there any way to disable the alarm? The alarm does turn off once I start the vehicle. Any suggestions is greatly appreciated, I am not mechanically inclined, however I am great at tinkering.

Re: Stupid Alarm....help!

I will have a look into the manual when im home, but when im not wrong should a switch in the door lock mechanism arm and disarm the alarm.

Re: Stupid Alarm....help!

Here attached two pages from the service manual which shows the door lock switch. This switch is most probably the problem. There are some test resistances on the attached pages, so that you can check the switch first. Maybe that some adjustment can be done to the switch, not sure about that.
If you really want, then the stealer should be able to program the BCM (Body Control Module) to disable the complete alarm function, but i dont know if that is wise. It even could be more expensive (the use of a DRBIII scanner from the stealer will probably cost at least USD$100) then just getting a new switch and replace it.

Re: Stupid Alarm....help!

How do you lock your doors at night? With the lock button on the door before you close it? If you do that you're arming the alarm. If the red light on the dash is flashing after you close the door then that's what's going on.Try locking your doors from the outside with the key after the door is closed. I'd bet that will take care of the morning wake up call. I don't know if it's a WJ quirk or an issue with the key cylinder switch itself but if I lock the doors with the remote or the lock buttons from the inside and I try to use the key to unlock that damn horn will go off every time. It's been that way from day one. I discovered this the hard way like you when one of my remote batteries died and had to use the key. Also they should be disable the security system because a replacement body control module doesn't come with the VTSS system enabled. It has to be turned on with the DRB3 tool so if they can turn it on then they should be able to turn it off. The thing to consider here though is this. Your jeep should have the key fobs with this system. Sooooo....... if your gonna pay a dealer to turn it off why not just have him program a new remote and have it the way it's supposed to be. I know that a few decent dealers around here will even program a remote for free if you buy it off of them so it might end up costing you close to the same anyway.

I dont know if there is a difference between American build WJs and European build ones (WGs like mine), but using the key on mine always disarms the alarm. Just tried it now to be sure, but locking the doors with the remote or with the internal lock switch on the drivers door panel for sure will arm the alarm, but using the key disarms it. Locking all doors with the internal lock switch, then manually unlocking the drivers door with the internal lock/unlock handle and finally locking that door with the key will NOT arm the alarm, so could be a solution for now.
I think a way to check if the key cylinder switch is working right, is to check if the internal lights come on as soon as you unlock the door with the key (so not opening the door yet).

Re: Stupid Alarm....help!

Has anyone added to their existing alarm a Glass Breaker Sensor? (it listens for thumps & smashing glass.) It sets off the alarm before a door is opened.
Can it be done?
My Lexus had the option for $150. and they just plugged the module in under the dash.

I was wondering if there is a way for it to be done without causing electrical havoc.

Re: Stupid Alarm....help!

Thanks Frango100 and Cheapjeep, I'm gonna try all this once it stops raining here. The factor here is there is no key fob, so unlocking it with the key is the only way. Am I understanding correctly, there is a way to program a new fob to the alarm system? If so that will be the route I take, mainly because I am lazy and usually have my hands full when I am trying to unlock the jeep. I will say it sounds a lot like the switch is worn in the door lock, as it seems to go off if I don't push the key ALL THE WAY left, however it just started to go off when I open the rear door after using the unlock switch to unlock the whole car. Thanks for the info and I'll let you all know the outcome when it stops raining here

Never heard of this for the WJ. I don't know how this sensor works, but there can be a signal wire left over if your jeep doesn't have the switch for the hood.
And yes, a new keyfob can be programmed, maybe wise to get a spare as well with the spare key. You can even get two different once, so that each will set the memory (for radio station, mirror and seat position). This ofcourse only works if your jeep has the memory function installed.
