T6.1 starting locking itself when inside.

[JonriceT6]

I have a t6.1 full camper conversion, which has recently had a service .
Since it’s service the vehicle has been locking itself whilst we are sitting inside, and therefore setting the alarm off.
Any idea what’s happening? And how do I stop it?

Thanks

Do the lights come on when you open the doors and if so have you checked each door individually?

Yes the lights come on when you open the doors.
The vehicle only seems to lock itself when we are inside.
If I leave it open and exit the vehicle it stays unlocked.

When this happens its normally because the door/lock sticks and the van doesnt register the door opening
By default has a 30 second auto relock so if you unlock the van and dont open a door it will automatically relock to protect from accidental unlocking
