I agree with TX! I waited to long and it cost me $195.00 to have the lock drilled out. Now I have two different keys as the locksmith couldn't duplicate the original lock due to being in a remote location. You might consider buying a new key from your MBZ agency and then have it duplicated for a back-up. I prefer brass to steel keys as I'd rather have the key wear than have to replace the tumblers in the lock.
