When locking my car, the car alarm goes off every time. How do you fix this?

fix the lock

I do not know how to "fix" the problem to make it right, but you can disable the alarm through the relay box or fuse box. You'll lose the alarm, but can lock the car. Several may be labeled "Alarm and... try to find one that is the alarm alone or something significant, if possible. Not an answer, just an Idea.

try changing battery in the remote

Hook your battery up, then use your remote to lock then unlock the doors a few times. Sensors in the door lock should reset the alarm. If you dont have a remote , use your key. Do both doors as sometimes one wont do it. Mike

sounds like the hood alarm switch is not making proper contact with the hood, the alarm will not set properly, check the hood alignment

first of all it sounds like an aftermarket alarm system.... do your self a favor have it removed. in va i charge about $60.00 to remove and put back like it was.. easy job... don't try to fix get rid of

Does it have remote central locking. If it does then it needs to be opened with the remote control. By opening the door with the key is the same as picking the lock to the alarm system so it put's on the alarm and imobilise's the car and actavates the alarm. Hope this help's Cheer's

Hey just wondering if you ever go this problem fixed. I am having the exact same issue. Thanks

if you have a valet key, stick it it on the passenger side when unlocking door, so it wont alarm while you open the door hope that helps

This car has a feature that can automatically lock your doors after you leave your car unlocked for a period of time – this can be turned off. I had the dealer do it but I am sure if you check the manual it can show you how to do it yourself. The alarm and locks on this car are very sensitive and often break so if this problem isn't resolved by deactivating the auto lock then I would have a mechanic look into it.
