The habitation door can only be unlocked by key from the outside, the remote key fob and the Ducato cab switches lock both cab and habitation doors and unlock the cab doors only. There is a slider lock button on the inside of the hab door which slides up to lock and down to unlock when working correctly but in this case it cannot clear the lock even with the key fob or cab switch. There appears to be power to the lock in that the slider switch "bounces" when the key fob or cab switch is actuated to unlock. I would appreciate any information on the lock ecause it looks like a major strip the door apart job. Some pics below.
