Deadbolt Installation in Broomall, PA

A door to your garage or basement may have only a knob lock.

That leaves you relying on the latch to keep the door closed and secured. In Broomall, we install deadbolts on entry doors so you have a separate way to secure the door. The bolt needs room to reach its full position in the frame, and the strike needs to line up with it. If there is glass near the lock, your choice of cylinder matters too.

A single cylinder deadbolt opens from outside with a key and from inside with a thumb turn. A double cylinder requires a key on both sides, which makes it harder to unlock through nearby glass but also means you must have it to get out. Consider how you would leave in an emergency before choosing this option. We install both types in Broomall and can match the new lock to the ones you already use if your locks are compatible. Otherwise, you will need a separate key for the new installation.

We look at your garage or basement door first, noting its material, thickness, existing knob lock, and the space available in the frame.

We explain where the new deadbolt would go and whether an existing opening can be used. Strike placement matters because the bolt needs enough room to extend fully into the frame, not stop short against the edge of the opening. We also check whether the entry closes and lines up well enough for the new hardware to work as intended.

You can choose a single cylinder model, with a key outside and a thumbturn inside, or a double cylinder model, which requires a key on both sides. Glass near the entry matters: a thumbturn may be reachable through broken glass, while needing a key indoors can make an emergency exit harder. If you want the new lock to match your other keys, we check whether the hardware is compatible and explain any rekeying needed. After installation, we check the action with you with the door open and closed. The bolt should extend fully and retract without forcing anything or pulling the door into place.

Test the deadbolt with the door open, then close the door and turn it again.

The bolt should reach the same fully extended position in both cases. If it stops short only with the door closed, it may be meeting resistance at the strike or frame. A partial turn is not a reliable locked position, so do not force the key or thumb turn to make it feel secure.

Keep the exterior clean with a soft, dry cloth, and follow the manufacturer's care instructions for the finish and moving parts. Avoid hanging heavy objects from your keys, which can put strain on the cylinder. If the bolt never reaches its full position even with the door open, or if it begins catching or takes more effort to turn, call us to check it. Changes in how the door sits can also make operation difficult.
