I've never seen the red blinking dot above the temp gauge until the other night when I hopped out of my Jeep and locked it with the key fob.


The theft system must've activated/enabled when I had some trouble getting the key out of the ignition switch.


How can I revert back to completely shutting off the theft system where I can lock my Jeep with the fob and it will not arm.

Check your owners manual. It's on pages 19-21 of the 2013 manual, it might be different for other years.

Yes, but this does not fully disable the alarm system. It basically tells me to unlock my Jeep if the alarm is going off. I don't want it to arm every single time I lock my Jeep with the key fob. It wasn't like this 4 days ago so I am very confused on how it was enabled.

I don't understand why you would want to permanently turn off the alarm.

If you use the fob to lock and unlock there is no problem.

The only time that you will set off the alarm when it is armed when you are unlocking it is if you use your key to unlock the door.

I would rather have the alarm then have my jeep stolen.

But maybe that is just me.

I'm not 100% sure how you were previously not arming the system by using the fob. The JK/U security system cannot be fully disabled unless you pull the fuse - but then your keyless entry won't work at all. Using the fob to lock the doors will arm the system. Using the fob to unlock the doors will disarm the system. If you unlock the driver’s door with the key and then re-lock it, the door will be locked but the alarm will not be armed.

I have news for you - every time you lock the vehicle with the button on the door it also sets the alarm. I discovered that after I had my Sahara for about a month. I pulled into a parking lot, locked the Jeep with the button on the door and started away. I realized I had forgotten something out of the front, and rather than unlock the entire vehicle, I walked up to it and unlocked it with the key in the passenger door.

And set off the alarm. Not knowing for sure what to do, I unlocked it with the key fob and the alarm went silent. In the year since then, I have not used the key to unlock the Jeep. In one way, I was lured to do it that way since there was a passenger door key slot. Most of the vehicles I have had with electric lock only had a key slot on the drivers door. I have not experimented with locking all four doors manually to see what the effect was, since I had not unlocked a vehicle with the key in years before that.

Manually locking the doors will not arm the system.

How does the alarm get set off when the doors are off?

 

[Londevil]

Does your jeep have the factory alarm ? If so lock the doors with the fob and then unlock the door with the key . The alarm will go off .

The alarm is only armed and disarmed with the fob.

 

[kik]

The Vehicle Security Alarm will set when you use the Remote Keyless Entry (RKE) transmitter to lock the doors and swing gate, or when you use the power door lock switch while the door is open.

If you don't try to lock the doors when the doors are off, the alarm will not be set.

I would say be sure to use your key fob to lock them when you leave the vehicle! LOL.

And would the alarm go off if you disturbed the doors while they were sitting on your nicely home-made PVC pipe rack inside the garage?

This thread is getting exciting now!

With doors off and alarm armed (set). What would it take to activate (set off) the alarm? I know just sitting in the jeep won't set off the alarm, I tried it.

Maybe the fact that there is no electrical load from the doors prohibits it from going off. When you use the fob to arm it when the Jeep is doorless, does it respond with the horn?

I disabled the "horn" when locking with the key fob. I doubt the alarm has a motion detector and probably requires mechanical action to active or set off the alarm.

I'm just wondering how the alarm is programmed to function when the doors are off.

 

[rgreen65]

I don't think it will arm. According to the manual, when either using the door power lock button (with the door open) or the RKE remote lock button to lock the doors, the security system will flash the security light (upper right over temp gauge) for 16 seconds after which it is armed. If any door is opened in that period, the system will NOT arm.

If you have your doors off, see it the security light will flash when you press the lock button. The only door than can lock is the TG.

Interesting question, though.

 

[sportcoupe]

So I did an experiment. I disconnected all doors electrical connector as if removing the doors. The alarm did flash fast for 16 seconds and then flash slowly, indicating the alarm was set (no doors).

I opened the hood, no alarm (sadly). I sat in jeep, no alarm (sadly). I manually opened the tailgate with the key and the alarm blasted.

There you go. It's not clear in the manual but the alarm will arm with doors off. Not much protection though IMO.

Call me crazy but I didn't see a fuse for the alarm, which one controls alarm/keyless.

For the record, I've got an issue where my keyless entry isn't working, but key works fine (so it's not the WIN/WCM). And the dealership agrees. All 3 keys are inop, starts and runs fine, but have no keyless entry.

 

[rgreen65]

If you lock the doors manually when you get out, they alarm will not be armed. Manually means with the mechanical lock buttons on each door. If you use the electric lock button on either the drivers or passenger front door when it is open, the system will be armed.

When you stop and open the drivers door, all the doors unlock. You may try to use the mechanical button to unlock just the drivers door when you stop and see if that leaves the other three doors locked, then lock the drivers door again with the mechanical door button, not the electric lock and close the door. In that case, the alarm should not be armed.

If all three keys fail to lock/unlock the doors remotely, then it is likely that the module under the dash has failed.


What is "WIN/WCM"?

Even with the doors off the rear gate is still active if the vehicle is "locked"
