Deadbolt Installation in Wilmington, DE

A bolt that never fully extends may be stopping against the frame instead of reaching its locked position.

On a Wilmington entry door, that can leave less of it engaged than you expect, even when the knob lock feels secure. We install deadbolts and set the strike so the bolt has room to throw cleanly into the frame. If the opening and lock do not line up, we check their fit and address the placement as part of the installation.

For your Wilmington home, you can choose a single cylinder model, operated from outside with a key and from inside with a thumbturn. A double cylinder model requires a key on both sides. That choice can limit someone reaching through nearby glass to unlock the door, but it also means you need the key to leave. If you want the new lock to match your other locks, we check whether the hardware is compatible and explain your choices if it is not.

We look at your entry door and frame to see where a deadbolt will fit and whether the surfaces meet evenly.

If a bolt cannot travel all the way into its opening, it may look locked while the mechanism has not fully engaged. We explain where the hardware would sit and what could keep it from extending fully. You can choose a single cylinder, operated with a key outside and a thumb turn inside, or a double cylinder, which needs a key on both sides.

Near glass, a double cylinder has no thumb turn for someone to reach through broken glass and operate, but you need a key to get out. We also check whether the new hardware can be keyed to match your other locks, based on compatibility. During installation, we position the strike so the bolt lines up with its opening and has room to extend fully. With you, we test it with the door open and closed, checking that it turns smoothly and reaches its fully locked position.

Your new deadbolt gives the front entry a separate lock from the knob.

If the cylinder begins to feel dry, use only a lubricant labeled for locks. Avoid household oil, which can collect dirt. Try the key and, if fitted, the thumbturn with the door open. The bolt should extend fully and retract smoothly without forcing either control.

If you have to lift or push the door to lock it, the bolt may not be lining up with the strike. A lock that turns only partway, catches or traps a key is also worth a closer look. Stop forcing it and call us to check the fit and operation. We can also check whether the lock can be keyed to match your other locks, so you have fewer keys to carry.
