Deadbolt Installation in Audubon, PA

A glass panel beside an entry door can make choosing a deadbolt less straightforward.

If your Audubon door has only a locking knob, adding a deadbolt gives you a separate way to secure it. A single cylinder model uses a key outside and a thumb turn inside, which is convenient when you leave. Near glass, though, that turn may be within reach through a broken pane. A double cylinder model has keyways on both sides, removing the exposed turn but requiring a key to get out.

We install both types in Audubon and position the strike so the bolt can extend fully into the frame when the door is closed. A bolt that stops short may not hold as intended, even if the lock turns. If you want the new hardware to match your other locks, we can check whether they are compatible for rekeying. Some combinations require different hardware or cannot be matched, so you may need to use separate keys.

We first look at the door's thickness and material, the space above the knob, and how the frame lines up when the entry closes.

A glass panel beside the lock matters because an interior turn may be within reach if the glass is broken. We show you where the deadbolt can fit and explain the choices before starting. A single cylinder has an outside key and an interior turn. A double cylinder requires a key on both sides, which limits access through the glass but can make leaving in an emergency harder.

If you want the new lock to use the same keys as your other entry locks, we check whether the existing hardware is compatible before you decide. We also explain where the strike needs to sit so the bolt can extend fully into the frame rather than stop short. We check the finished fit with you, first with the door open and then closed. You can try the operation yourself and see that the mechanism turns freely and extends all the way when the entry is shut.

If you chose a double cylinder deadbolt near a glass panel, it needs a key on both sides.

Keep one for the inside where you can reach it easily, but consider whether someone could reach it through the glass. Make sure everyone who uses the door knows where it is and how the lock works. A single cylinder model has an interior thumbturn instead, so there is no inside key to keep track of, but the turn may be reachable through a broken panel.

Test the bolt with the door open and closed. It should extend fully without pushing or lifting the door. If it catches, needs force, or no longer turns smoothly, avoid forcing it. Keep the opening in the frame clear of dirt, and follow the manufacturer's care instructions before applying any lubricant. Call us again if the bolt will not extend fully or the strike no longer lines up. We can examine the fit and determine what needs adjustment.
