ive got a toad alarm centrall locking system,, and when u close it it works and re opens it self, could this be due to a solenoid gone and somthing else?

 

its one of the door motors mate one will be clicking all the time mate

 

first of all make sure your locking mechanism is not seizing up and is working ok, then i would suggest removing your speaker covers in the front footwells and checking the plug that connects to the central locking motor (think its the white/clear plug) these pretty much always corrode and play up, i just reomved mine a soldered the wires back together eliminating the plug, worked a treat and has been fine for over 3 years, may help you out.

 

Could be broken wires getting pulled through the door.

 

What he said - check the plug behind the speaker - drivers side. Mine was shorting out on the chassis and causing the doors to unlock then lock straight away.

The other one is the electronic boot lock. Try unplugging it and see if it cures the problem.
