I need a complete lock set 78 240d
 

Does anyone know of a good source for door and boot lock sets? I would prefer NOS or at least aftermarket but a complete used set w/ keys would work great too. Car was from an auction (before me)with no keys. The doors cores look ok and could be re keyed but I still need the complete trunk lock because the kid I bought it from knocked the lock completely out with a hammer and chisel and proceeded to lose it after. I'm new to Mercedes so any resources are a big help!

I have replaced the ignition already. I guess my point is that I don't want to have 3 different keys for the trunk, ignition, and doors. Thanks for the info in replacement keys from Mbz I will check into that.
