I HAVE A ELVATOC/APS2K4SBCF. MY ALARM GOES OFF AND I CAN'T TURN IT OFF WITH THE REMOTE, THE HORN HAS BEEN DISCONNECTED AND NW IT CLICKS INCESSENTLY. HOW DO I SOLVE THIS PROBLEM?

Your alarm should turn off with remote. If won't my wild guess is that somehow your alarm got short-circuited.
Does your car start with alarm on but anti-theft turned off? If does, disconnect horns and take your car to alarm installer to get it checked.

well if the alarm goes off the car thinks that bad guys are IN it so thats why you get locked in.

You will need to replace the horn pad or disconnect the horn. Your choice.

This may be stupid but have you locked and unlocked the
drivers door (with the key,not the remote)?

Repair your vehicle right away. Just click on the link I attach 2005 Chrysler Sebring Sedan Workshop Service Repair Manual

That is the security system coming on.

You alarm system monitor the radio. You basically disabled the vehicle when you removed the radio. You will need the original radio with the radio code and install it back. Your driver door lock is what turns it off and what turns it on. You have a 1996 Jetta find a electrical auto repair who is willing to do this (I do this all the time) Disable the alarm first get rid of the horn there is only on on the outer drivers side the alarm horn will have to be cut. From there acces the fuse box under the driver dash find the starter relay and bypass it. There your done no alarm and you can put any radio on .

If you can try resetting your remote, and change the batteries if you can't reset it ask a dealership how to

If you can't stop it with the remote, then find the fuse panel and look for the fuse that goes to the alarm. If the car's horn is honking, raise the hood and disconnect the horns.

This is probably a temp thing...night brings colder temps. The wiring may be failing or the steering wheel portion over the horn might harden and cause it to touch the center of the horn to make it go off.
Let me know if this helps.
