Master Key No Longer Works!

My master key will not fit into the lock on my 1988 420SEL to disable the alarm! Anyone ever experienced this problem? It just baffles me! I have disabled the alarm by inserting the MS key in the trunk lock to disable alarm. Today it just will not work! Any help is appreciated. Thanks - blajj.

The key is probably worn.

Since you are in Maryland, head over to Euro Motorcars in Bethesda or Germantown (or whatever dealer is closest to you) and order a new key. You will have it before the weekend. Costs about $20.00.
