Locks

[thowman]

I need to change the locks on my Berlingo. It's a 2001 Multispace, and none of the locks work on the doors. I can see lots of sets on ebay, but all the cheap ones seem to be for a twin rear door - whereas I have a single door. My question is can a lock for a twin door be converted to work in the single door?

I also guess the keys are all coded, so if I were to replace the ignition lock, I'd need to get the new keys coded to the old single key I have?

Thanks

Andy
