Just how much does a new lock cylinder and key cost? I have the same problem with my 420SEL. The driver's lock has not worked from the outside since I bought it, and the trunk has not worked the central locking system except for two freak occurances that I can not explain. The dealer told me a new lock cylinder would cost $1000. That is not cheap. Are they trying to rip me off, should it be less than this?
