Hi

When I lock the doors there is a noise in all the doors like the central system is trying to unlock them and lock them back in a millisecond... The doors stay locked but the battery went down so I change it... Do you know on what part of the electrical this problem is? Doea it has to do with the immobilizer? An alarm system also is installed in my car. Is it possible this causing the problem? How can i disable it to check? The biggest noise comes from the back door's lock system...

Thanks
Jim
