Toyota Aygo Locking Problems

[Atlam15]

I have a Aygo 2005, when I lock the car using the key fob, after a few seconds it unlocks it self. Checked key and replaced Battery, still the same happens. Taken Battery out of key to use manual locking and that is fine. Any ideas what might be causing this?

i would have a look at your door lock motors as i feel one of them is faulty ,all locks need to give the central door locking system a lock signal and if one of the motors is giving an unlock signal then they will all unlock.

to isolate a motor disconnect the multi plug from the door lock,

isolate 1 lock then try locking if it locks great if not re connect the plug and go to another door until you find the one thats faulty.
