Jeep Cherokee 1994 When I press the key fob the system flashes twice, the alarm & imobaliser are set but the doors are not locked

Speaking from prior experience, It's possible that the door lock latch assembly may need replacing usually the drivers side or the lift gate latch assembly. These are the 2 that can arm & disarm the alarm system. You may have a faulty switch in either of these. Hope this helps.

Hi there:
Open the drivers door and turn the key to the on position. Lock the doors with the switch on the door. After the doors lock point the transmitter to the little bulb on the ceiling. Press the LOCK button and hold it until the doors unlock.
I suggest to check this article and this VIDEO link.


Good luck.

Inset the key into the driver door and turn to unlock position three times to disengage alarm system without remote. Do the same in lock position for setting alarm without key fob.

This should not happen, you have a defective door ajar switch i suspect.

The security alarm system on the 1994 Jeep Cherokee arms itself on any normal exit from the vehicle, i.e. ignition off, open door, lock door with power door locks, close door. If the doors are locked with the key, it does not arm.
If the battery is disconnected, then reconnected, the alarm system will go into powerup alarm mode. The lights will flash, but the horn will not blow.
The alarms can be disarmed by a keyless vehicle remote or by unlocking either of the front doors or the read lift gate with the key. If the key method does not work with any of those three entrances, there is a problem either with the input to the alarm module or the module itself.
There is a switch in both front doors and the tailgate which is activated by manualy unlocking those doors. The alarms can be disabled by permanently grounding the wire going from either of those switches to the alarm module, but this will remove all theft protection.
The best thing to do is to find out why the system is going off in the first place. It could just be a glitch, a loose connection that can be fixed fairly easily and keep your theft protection intact.

If ithe alarm is factory when they will have to reset the alarm module with a scanner. If the alarm if aftermarket go to the control module and see if it has a reset button. FOBs (remote) can reset alarm. You Jeep is always set for break-in mode. The FOB sets this when ever the FOB is used to lock the doors. May be bad alarm module - Sorry - Good luck

Some Jeep models have the ability to reset the alarm by following this procedure. Connect the battery cables and allow the antitheft alarm to trigger (usually horn honking and lights flashing). Use your ignition key to lock, unlock, lock and unlock the passenger front door. This should reset the system to be used normally. If your key fob is the problem, remove batteries to stop alarm trigger and have dealership test and/or replace fob. Hope this helps.

there are two buttons on the diagram panel screen, push and hold top button and a one of the entries will start to blink, then you use the bottom button to change the entry, when you are ready to move to the next entry push the top button again.

You might try locking all the doors from the inside and then closing them all. Then try unlocking the car with the key itself (NOT THE FOB) manualy. Try a combination of these things, like maybe locking it manualy with the key itself too. Usualy some sort of locking or unlocking manualy with the key will reset the system. Its almost luike proving to the car that you are who you say you are.

The ignition security on/off is located at the trunk lock. unlock and lock rear gate and the alarm will turn off. My jeep sat in my drive for a month before a jeep tech told me this. It still triggers the security sometimes when I unlock the passenger door with the key and I go straight to the rear gate lock and it shuts off instantly.
