Only at night the alarm goes off and shortly thereafter the horn starts blowing and then the locks starts to unlock and lock and repeats.

Just to be sure I understand, this is happening every night and it goes off by itself? If this is the case then we need to check the battery voltage and alternator to make sure they are ok. A lot of times, low voltage will cause all sorts of crazy things to happen.
If that checks out then we need to have it checked for codes to see if there is anything that will point us in the right direction.
