To arm content theft alarm. 1. Open the door. 2. Lock the door with the power door lock switch or the remote keyless entry transmitter. The SECURITY light should flash. 3. Close all doors. The SECURITY light should go off after approximately 30 seconds. The alarm is not armed until the SECURITY light goes off.
If a locked door is opened without the key or the remote keyless entry transmitter, the alarm will go off. The headlamps and parking lamps will flash for two minutes, and the horn will sound for 30 seconds, then will turn off to save the battery power.
Door Key Switch
The BCM monitors the door key switches in order to disarm the CTD system. When the lock cylinder turns in order to unlock the door, the switch grounds the disarm input to the BCM.
The key lock input to the BCM is probably missing , BCM doesn't see it . So it think's your breaking into the vehicle. Did you try the passenger door to see if it will disable the alarm .
The BCM - body control module ! Electronic -computer !

Content Theft Deterrent (CTD) Does Not Disarm with Key Lock
The factory service repair manual has a 23 step diagnostic procedure . An you would need a factory scan tool to find the correct fix.
Turn ON the ignition with the engine OFF.

Does the scan tool display INACTIVE?

The Vehicle Security Alarm is designed to protect your
vehicle; however, you can create conditions where the
Vehicle Security Alarm will arm unexpectedly. If you
remain in the vehicle and lock the doors with the RKE
transmitter, once the Vehicle Security Alarm is armed
(after 16 seconds), when you pull the door handle to exit,
the alarm will sound. If this occurs, press the UNLOCK
button on the RKE transmitter to disarm the Vehicle
Security Alarm. You may also accidentally sound the
Vehicle Security Alarm by unlocking the driver's door
with the key and then opening the door
good luck deciphering this page, wow.!
page 23 is NO ENTER AND GO', OPTION.
Either press the UNLOCK button on the RKE transmitter,
pull on the front driver or passenger door handle (refer to
"Keyless Enter-N-Go" in "Things To Know Before Starting
Your Vehicle" for further information) with a valid
key fob in range, or press the Keyless Enter-N-Go Start/
Stop button (requires at least one valid Key Fob in the
vehicle), or insert a valid Key Fob into the ignition switch
(if the Start/Stop button is removed) and rotate it to the
ON/RUN position.
END QUOTES FROM YOUR GUIDE.
if all this fails get jeep to fix it. (the magic is broken so...)
or ask them to explain, page 23 , in non GREEK..
Ford sold a Ford branded alarm through the parts department. These sometimes were a dealer installed option on new cars. Mine would randomly stop responding to the remote and I would have the same symptoms as you describe. I had it removed and the original equipment factory system still worked. Be warned, if you have the Ford "accessory" alarm, your key fobs (remotes) are different and the method to program them is different from what you will read online. You can tell if you have the system by looking at your key fob. The standard Mustang key fob is a 4 button (lock, unlock, panic, and trunk). The accessory alarm uses a 3 button remote and clicking unlock twice would pop the trunk. I really wish I had a picture of the remote because there are 3 button Ford key fobs for cars without a trunk release although I don't think you should have one on a Mustang. Long story short, if you have the accessory alarm, you can solve your problem by having it removed but you will need new 4 button key fobs to remotely lock/unlock your doors
If this aftermarket alarm is playing up then the best bet is to remove it completely before it packs up completely and leaves you stranded out in the middle of nowhere on a cold dark night.Any after market alarm or remote start is problematic when they get older and highly prone to going wrong owing to the complexity of the circuitsa and the fack they use inferior integrated circuits made in china
you may have a bad door switch, theres a switch on the drivers door lock, when door is unlocked with fob or key the switch is activeated to shut alarm down,the lock moves to hit switch with key or fob,so if the switch is bad it will not shut down alarm, i would start there,door panel has to be remove,then latch has to be remove to get to switch, then test with a meter see if it opens and closes the connection, hope this helps.
This does not sound like a fob fault - but a locking control module fault , either in the hardware or software of the unit. Get it checked at a Jaguar dealers. When unlocking using the key - as soon as the door is opened you should hear a chime sounding inside the car - this is a timer counting down to sounding the alarm. If you put your key in the ignition as soon as you open the door the alarm should not go off and the chime should stop. If it does not this again points to a fault in the locking controller.
hope this helps - good luck.
Do you have a key fob? Unlock the car with that and you should be OK. My sons Elantra is the same way, you can only get in with the fob. I guess the car thinks it's being stolen otherwise. If you don't have a fob, I'm no help
