Master Lock Co 5400D Key Storage Lock with Shackle

Product Description

The MASTER LOCK CO 5400D is a key storage lock with a shackle, designed to securely hold and dispense keys at job sites, rental properties, and service locations. The 5400D features a 4-dial resettable combination that lets the installer set a custom code without tools. The reinforced body resists hammering and sawing, while a shutter door provides enhanced weather resistance for outdoor placement. A vinyl-coated shackle prevents surface scratches when the lock is hung on a door handle, gate, or fixture. Trade professionals managing access for tenants, inspectors, or service crews rely on this type of device to eliminate the need to be on-site for every key handoff.

The 5400D is suited for residential and light commercial applications where controlled key access is required. It holds over 5 house, car, or padlock keys inside the storage compartment. The key storage door pivots open smoothly and remains attached to the lock body during operation, reducing the risk of losing the door on a busy job site. Typical installations include door handles, railings, and similar mounting points accessible by an authorized shackle hang point.

Installation Notes

Installation requires no tools — hang the shackle over the intended mounting point and set the combination per the manufacturer reset procedure. Confirm the shutter door closes fully and the combination dials are scrambled after each use. For outdoor installations, position the lock so the shutter door faces downward when possible to shed water and extend service life.
