Silly question! How to turn off the alarm?

Once in a while my alarm goes off when I open a door/hatch after unlocking it with the fob.

Nothing I seem to do makes it happy again -- re-closing all the doors and fiddling around with the fob doesn't do anything and I have to resort to d/c'ing the battery.

Is there something I'm missing?

I'm thinking of just installing a battery switch...

If the key fob doesn't do anything believe if you put the key in the ignition and turn it on/off without starting it will turn the alarm off then reset everything.

When my WJ decides to act up I have to physically start the vehicle. Even if I disconnect the battery it will still go off after reconnecting the battery. No matter how long its been disconnected. But my PCM is also slowly dying and doing weird things all the time. So just cycling the key may work for you.

I tried starting it, and it merrily kept honking away, but in my case the disconnect for a bit helped -- I opened and closed all the doors and the hatch before reconnecting.



I'll probably have to work up the gumption to dig into the door wires.

When you tried to start it did it not start? Next time this happens check on your dash for a key symbol with a circle around it and a line through it. If it is on then I would suspect a problem with your skim or pcm. I would lean towards the pcm if disconnecting the battery worked. Sometimes resetting the pcm will temporarily fix the problem. Do you have any other issues. Like stalling while ideling? No speedometer or other guages not working. Rough idle, sometimes? When your pcm is failing your jeep will do a bunch of weird things. It looks like wiring problems but is really the computer. Electrical problems are my least favourite. Good luck. Lol

For me, the alarm will turn off once I crank the engine. It might with key on too but I just automatically crank it in the process.

For why it happens, I found that the lock mechanism in the driver's door had something to do with it. For example, if I unlocked it with the key but I don't see that the interior lights turn on with the unlock movement, the alarm will sound. It's like the mechanism to unlock isn't fully reaching the travel necessary to register that the key was used. When the fob unlocks the door, the same mechanism seems to be involved.

I started unlocking by the key only and began turning the key a little further towards unlock and then pulled on the key a little and normally can see that the interior light does come on. That tells me the car recognizes the key is being used and responds...quietly to it, rather then thinking I've just smashed the window and unlocked it from the inside.

After losing my 3rd or 4th FOB I only use my key now as this Jeep is now just my Toy. But now that you mention it. When I unlock my door quickly and just turn the key pull it out and open the door. My alarm goes off. When I take the time to turn the key slowly and go through the motions theres no problem. Maybe im gonna have to clean up the door mechanism as well. Ill add it to my long list of fixes. Lol

Started just fine, and no key symbol. Just honk-honk-honk.

It idles rough in open loop, but it's got 240k+ miles on. I just give it a few to warm up and it's fine. No codes since I replaced an 02 sensor and the coil pack.

Lol, peel out in the apt parking lot with the alarm going. Up my "crazy white bozo" street cred.

That might be it. Normally I open it up halfway down the stairs instead of right next to it which gives it time to realize everything is okay.

I also got a new case for the keyfob, the buttons were sorta rotten and squishy on the original, so it's possible I bumped the lock button when opening the door -- it doesn't like that much.

Neg battery cable was cracked, could be a contributing factor. I had an inexplicable no-start the other day that finally make me poke around more.
