How does one replace a lock barrel for a habitation door?

[SurreyNick]

Previous owner lost the keys for the FAP type habitation door lock on our Niesmann + Bischoff motorhome. I thought I could just buy a replacement FAP M1 internal lock thinking it has the lock barrel and keys, but no, it doesn't. So I guess I need to buy a FAP system lock and keys, and swap old for new. Does anyone know how to do this? Also do I need to buy a FAP new system removal key to get the old one out and/or fit the new one?

This is the lock we have.

Any ideas out there?

Think you need the removal key to get the old lock out

FAP FW Removal Key - Replacement Keys Ltd

Change key for extracting Fawo FW barrels so they can be replaced or to obtain the key code marked on the side of the barrel. Will only extract Fawo FW barrels that are unlocked .

Hi is the lock unlocked? If so it makes it much easier. You can then use the unlock key to remove the barrel. I had the same problem. I took my barrel to a master locksmith, he made me two keys for £30, it took him two hours. I think that was a fair price. Most "locksmiths" can't do it. If the lock is locked you need to take your moho to the guy (or pay callout charges). Good luck.
