Separate entry control from emergency exit
This scenario assumes a restaurant near Dupont Circle with a public entrance and a rear delivery door. The rear door is used heavily and does not latch consistently. Replacing its cylinder would not resolve the closing problem, and adding an improvised bolt could create a more serious exit hazard.
Have the responsible building professional confirm which doors serve required exit routes and the hardware appropriate to the occupancy. OSHA’s workplace exit-route standard generally requires employees to be able to open an exit door from inside without keys, tools, or special knowledge. Local building and fire requirements also need to be addressed for the actual opening.
Make deliveries part of the design
Discuss when suppliers arrive and who receives them. If staff prop a secured door open to unload, a stronger lock does not solve the operating problem. Decide how a delivery is announced, who releases the door, and how it returns to a closed and latched position.
Check hinges, closer adjustment, frame fixings, and damage around the strike. Select hardware for the opening and its use, rather than choosing solely by the appearance of the handle. Any proposed change to listed fire-door hardware needs the appropriate technical review.
Plan around shifts and opening hours
Assign the manager who may authorize new keys or codes. Keep a record of issued credentials and change access when staff leave or a key is missing. Temporary access for maintenance should have a defined end point.
Agree the working area and sequence before a real installation so staff know which entrance remains available. At handover, test normal entry, closing and latching, and exit operation. Avoid promising uninterrupted service before the actual repair scope is known.
