Hello, I have a Mclouis on a Fiat Ducato about 5 years old and parked up overnight in a large Spanish Service Station a few nights ago and got "broken into". I locked the cab doors and the light confirming came on, yet in the morning, the light was still lit and the passenger door still locked but the drivers door was UNLOCKED and the obvious entry point. No marks on the door at all and no Fiat alarm went off. Now the insurers are trying not to pay up for the losses as there was no physical sign of a break in. Any ideas how the thieves did it?
