So the keys / locks that came with my 81 300sd w126 are starting to fail in the door locks - I have to be extremely careful with them to lock / unlock the doors. The ignition and trunk lock seem to be ok for now - however given the age of the car I think I should look at replacing. How / where is the best way to update all of the locks /ignition / trunk so they are all matching? Better to get an entire new set or have them re-keyed?


Thanks in advance!
