Hi,
So I leave my M3 parked up and drivers door in the deadlock position, all very good until recently I returned to unlock the door and found the key incredibly hard to turn like the key was going to snap and when I did unlock it the door popped open to the first latch at the same time.
Some lube in the key hole and a few tests found it gritty and still stiff but not as bad.
Over the last year I have collected up some parts for the door and window system for a refresh so good reason to get busy now.
I ordered a new lock o/h kit, main door lock, solenoid and the plastic grommets for the lock rods some from ebay and some from Pelicans
The door key lock overhaul kit p/n 51219061343 is basically a new lock completely disassembled with all the parts except the rubber gasket which I swapped over from the old lock.
Oven tray and towel come in handy.
Some where not shown in this photo there is a small roller which goes inside of the 90 deg arm.
In the kit are two bags of lock plates they are numbered 1 to 4 in each bag.
The inner 4 lock plates have to be the narrow “S” type this allows the lock to turn through to the dead lock position.
The way to work all this out is install a spring and S lock plate then the key and keep working through the 1-4 numbers until the lock plate is flush with the key cylinder.
Then it is a matter of slowly removing the key keeping the previous lock plate contained in your fingers and installing the next one.
Then just slowly try pieces of to puzzle until it looks correct.
The nail is for testing purpose until I was happy then in went the roll pin
