A lock housing and lock assembly unit for use with electric and gas fuel meter enclosures and the like is disclosed, including a lock plunger for mating with a locking stud and biasing means for urging the plunger into the lock position. The plunger and biasing means are captured within the lock housing by a cap which is press fit or otherwise permanently installed in the housing or made of part thereof. Temporary detent means may be provided to position the plunger in the open position prior to installation. A key is inserted through a key hole in the cap and in a socket in the plunger to withdraw the plunger to the open position within the housing. The invention lends itself to various plunger-stud mating designs and is adaptable to lock-key surface mating for selective key operation.
