On Feb 26th after owning this car for 4 days I was involved in a slight fender bender. The car sit at the towyard for about 2 weeks before the adjuster came to evaluate the damage ect. When I went to unlock the door the alarm went off. Took me a minute to figure out how to turn it off by inserting the key in the ignition and turning it on.
Now it's been another 2 weeks and the car is fixed but that problem still persists. It's gonna get annoying for everyone with the alarm going off at 2:45 AM every time I go to work.

The original key is being kept by the car dealer until it is paid off. I assume they have the keyless entry remote as well.

Any ideas on how to fix this problem?

 

find the speaker for the alarm and cut the wire.

 

The dealer is keeping keys for the car? Those should be in your possession, for starters. They do not own the car anymore, either you or the bank do.

 

At the complete risk of sounding like a jerk, but, did you fall and bump your stupid? I'm not cutting the wire to the horn.

@darthroush
The dealer still owns the car technically.
Their excuse is:
"In case you lose your key we can make a copy"
But you can see through that. Besides. I'm a locksmith. I can originate my own keys and change the locks.

 

Are you paying the dealer directly for the car? If not, they don't own anything technically. The lienholder, which is financing bank, or yourself are the owners of the car once you buy it from them. I'd call the bank personally. That is very odd. Tell them the alarm is freaking out then and you need the original key and key fob (remote) to fix it? Perhaps you could contact your insurance company and tell them this has been occurring since the accident, and you need it fixed since the issue wasn't known at the time.

 

If you don't like my original idea try this. Pull all the alarm bits out and get it fixed or deal with it. you asked for sugestions I gave you one. And like Darthroush said either you or the bank should have the original key. The dealer has no use for a key to a car they don't own unless they plan on repoing the car.

 

Yes, that's the deal I'm paying them directly. The issue has a solution that for the time being is getting dealt with. The switch in the driver side door is either faulty or has a bad connection.

The "alarm bits" pretty much involve everything under the dash. Which involves the car's ECU. out of the question.

 

Ah, OK. The door switch is an easy change though. Good luck with it!
