The spare wheel lock has come off my 2012 G350. I cannot work out if I am missing a piece or if something has broken. I’ve attempted to contact the manufacturer in Germany and get no response so I’m hopeful someone on here might point me in the right direction. Thanks

Looks like it is drilled out on the lock cylinder. Possibly a previous owner lost the keys and just drilled it out and left it as is?

The lock cylinder looks familiar, but the rest of the parts do not.

You can get a replacement lock:
