Your panic alarm is trying to go off for some reason. I had this happen once, and it was just a low battery in the remote lock control on the keychain. I also had one that turned out to be a wiring harness shorting out. First change that 2$ battery, If that doesn't help--my condolences!

If your vehicle is equipped with a factory keyless entry system and you have the owner's manual, there should be a section in the manual describing how to change your options with your system. But if you have an aftermarket system, which I am thinking this the case, you will have to manually go into your dash under your steering wheel and cut the wire going to your horn from the security system. Once you have accessed your wiring underneath your steering wheel, there is a main harness with a bunch of wires going to the steering wheel. In this harness you will find a DARK GREEN/VIOLET small gauge wire and you should see another wire tapping into it probably coming from the security module. Just cut it off but leave the DARK GREEN/VIOLET untouched and this will eliminate the horn honks.

find the horn ,it should be at the front possibly behind the bumper ,run a wire direct to it and see it works ,if it does work then its the wiring in the steering wheel ,but as this vehicle no doubt has an air bag then entrust this job to a garage because if you get it wrong the air bag will explode ,expensive job to say the least

There is a technical service bullitin from chrysler addressing this condition. It may or may not be related. Your going to have to retrieve the code to begin with. There really isnt anything you can be done at home and there is no reset procedure for the alarm. If this is related to the TSB then its possible a computer mudule failed but the only way to tell is with a diagnostic procedure recommended by the manufacturer.

if the horn is going off when you turn the steering wheel that means there is a loose wire in there. or the clock spring is broken, what i would do is have someone who knows how to deal with air bags take it off and check the wires it shoule only take 30 min to check, and if to much to repair they can disconnect it right there.

1st check fuse. Then see if power is coming to horn. A simple power checker can be found at most auto parts store. It may also have a horn relay. Look up your wiring at cargrus. If you still have problems contact me back.

Where is the fuse for the horn on a PT Cruiser

now sometimes this happens to let you know that one of the doors are open
check your doors
this is the only thing i can think of altho you have most likely checked it lol
also lock the car with the key
you don't want it to get stolen

Being that this is a 2008 pt cruiser, I would take it back to the dealership and let them look the car over!! Should be covered under warranty!!
