Deadbolt Installation in Abington, PA

A back door that feels weak may rely on a knob lock as its only barrier.

In Abington, we install a separate deadbolt to give that entry another way to stay secured. The hardware matters, but so does where it meets the frame. We position the strike so the bolt can extend fully into its opening instead of stopping short against the edge. If it turns only partway, it may not provide the hold you expect, even when it seems to catch.

A single cylinder opens with an outside key and an inside thumbturn. A double cylinder needs a key on both sides, which makes it harder for someone to reach through nearby glass and unlock the entry. The tradeoff is that you need the key to get out, too, so consider how you would leave in an emergency before choosing one. If you want your existing house keys to work with the new installation, we check whether the hardware is compatible. Matching is possible with some combinations but not others, so you may need a separate key for your Abington home.

We look at how your door closes, its thickness, and the space between the existing knob lock and the frame.

Before work begins, we explain where the deadbolt would fit and which choices suit the opening. A single cylinder has an exterior key and an interior thumb turn. A double cylinder takes a key on both sides, which limits access through nearby glass but also means you need a key to get out. We also check whether the new lock can be keyed to match your other locks, since the key designs must be compatible.

We set the strike so the bolt has room to travel fully when the door is closed. If it stops short, the lock may feel engaged even though the bolt has not reached its intended position. We check its travel with the door open and closed, then show you how it operates with the key and the interior control. You can try it yourself and feel whether it turns freely, without having to pull or push on the door.

With the door open, turn the thumbturn and check that the bolt extends fully and retracts smoothly.

Try the key from outside, too. A garage or basement entry may collect dust or dampness, so wipe the hardware with a soft, dry cloth. If the deadbolt becomes stiff, use only a lubricant labeled for locks, following its directions. Avoid household oil or grease, which can collect grit.

With the door closed, the thumbturn should move without your having to push or pull on the entry. If it catches, the strike may no longer line up with the bolt. Do not force the mechanism or keep using it if it will not extend fully. Call us if the key sticks, the hardware feels loose, or you need to push or pull to secure the entry. We can check the fit and identify what is keeping it from working smoothly.
