If it is the same type of lock as on my IV-P baggage door, it is called a ‘tubular’ lock. Any locksmith should be able to work with it. If you do a web search for ‘tubular lock lockpick’ you will find many to choose from.

Since my L320 key is the same “Ace” as several others, but with different 4 digit code, it appears these come with many different codes, maybe 9,000?  Wouldn’t be much of a lock if other codes worked.  Can these be picked?  If not, Andres, you may have to grind off the chrome face and drill it out.  Chicago lock or a good locksmith can then replace it.  I’ll drill it out for you for a ride in the L4.
