I had an intermittent drivers door lock, so I bought a new one on ebay and today I installed it. Everything is working except one thing has changed, before if I used the door lock button on the drivers door all doors would lock and stay locked, now the drivers door locks then unlocks again, This also happens when the doors auto lock at 13km/hr.

If I lock them with the keyfob they all work correctly and the alarm arms (red led flashing)

I had the door lock disconnected for a while, could the controller need resetting or programming ?

Anyone know what could cause this or the fix?
