Abstract
A lock device includes a housing and a removable cylinder normally retained in the housing by a rotatable retainer ring. The retainer ring is driven by a shifter and cylinder change key between a locked and unlocked position. The retainer ring is normally biased to the locked position so that tabs associated with the retainer ring will engage appropriate locking channels of the cylinder and retain the cylinder in fixed position in an opening of the housing.
