Need to replace worn out glass sliding door lock

A handy person from Novato, California says:
Lock on sliding glass door appears to be worn out, door won't stay fully locked, can pull door about 1/2 inch away from frame even when supposed to be locked. Can then easily unlock door with a credit card or similar.

On the white plate with the lock handle I see A/W. On the metal place in the door frame I see 7700B-.

I would like to swap in a new lock unit without having to drill new holes in either the door or the frame. Do you have one that will work? Thanks!
