The car alarm won't shut off

I just had the same prblem. Reconnect your alarm first of all. You need to use your key bob "remote" to deactivate the alarm before starting. It is a feature "good one" i might add that should someone try to steal it the jeep will not start until u deactivate it w theke bob.

Is it factory alarm or aftermarket??. Try using the key to lock and unlock the doors driver and passenger then turn the ingnition on with the key and leave it in the key on engine off position for a few minutes and start the vehicle

Look for a little antenna in the middle of windshield if it has a button on it press to reset. If not look for a kill switch usually on plastic under steering wheel on TH left side around where the bottom of your leg is when u sit in car if you find one switch to opposite other position . If that doesn't work you have to find out what wire is stopping power to your ignition if there's a local alarm place I would suggest having them take the alarm out and back to factory

Try changing the battery inside the remote usually that solves the problem but otherwise u might also have broken or loose parts inside the remote from dropping it on the ground,or rubber gasket maybe in in perfectly, if none of those solutions work, it may need to be reprogrammed or replaced,from the dealership.
usually its the coin cell battery eg:2016,2032,etc
and u'll need a small flat precision screwdriver and some patience when opening it.

alarm its self goosed may have to take it to an auto electrition to disconect the old alarm

Do you have another key ? Try that one and see what happens. Sounds like your old key fob is not making contact with the pcm.have it cheched out

Most models with factory alarm system can be reset by locking and unlocking the driver's door with the key.

The 'Keyless Entry & Burglar Alarm System" is activated. You must 'Disarm' the system using the Keyless Entry Remove (Key Fob) to "Reset" the system. The reason the engine won't start is due to the burglar alarm - it has a "Starter Kill" circuit which is activated when the alarm is activated. The alarm must be DEactivated to DEactivate the 'Starter Kill' circuit.
Another way to start the engine is to get in the car, put the key in the ignition and turn it to 'ON" and wait 3 to 5 minutes until the emergency flashers stop/turn off. Afterward, you should be able to start the engine. NOTE: This does NOT reset the burglar alarm. It will go off again when you enter the vehicle without using the remote/key fob.

If the passkey is messed up, there will be a light on the dash that says security, or have a picture of a car with a lock thru it. If there is no light when the key is turned forward, then its NOT a passkey problem.
