I had a van like that. When I was camping with 2 other van families and locked my keys inside there were so many locks to try with my friend's keys that we got in no bother. I have a very easy way to break into some types of late bay's including mine but I keep stum.
This is a proper functioning rear door lock on my C15. The barrel kept falling out and the wafers getting lost. I bought a new one last year but not got round to fitting it as this still works. It still drops out tho so I have to lock it while driving.
