What to know
Strengthen the complete door assembly
A strong lock cannot compensate for a weak door, loose frame, damaged strike plate, or short screws. Security improvements should consider the entire entry system.
Inspect exterior doors and frames
Check for cracks, movement, gaps, loose hinges, damaged frames, and hardware that no longer aligns correctly. Doors that do not close or latch properly may reduce the effectiveness of the lock.
Improve strike-plate attachment
Where the door and frame allow it, longer screws may help secure the strike plate more deeply into the framing. The correct hardware depends on the construction of the opening.
Control spare keys
Avoid leaving keys in obvious outdoor locations. Keep track of who receives copies and rekey locks when keys are lost, stolen, or not returned.
Rekey after occupant or staff changes
Homeowners, landlords, business owners, and property managers should consider updating access after tenant turnover, employee changes, roommate changes, or a lawful eviction.
Use lighting and visibility
Exterior lighting, trimmed landscaping, visible entrances, and maintained cameras may discourage unwanted activity and make suspicious behavior easier to notice.
Consider locks that match the property
Homes, storefronts, offices, rental properties, and warehouses may require different lock and door-hardware solutions. The best option depends on the door, frame, traffic, and access needs.
After a break-in or attempted break-in
- Contact law enforcement when appropriate
- Photograph damage before repairs
- Inspect the door, frame, lock, hinges, and glass
- Replace damaged hardware
- Rekey when keys may have been taken
