Why does my deadbolt only lock when I push or pull on the door?
Because the bolt is hitting the edge of the strike plate or the frame instead of sliding into the hole. Pushing or pulling the door lines them up for a moment. The usual fixes are moving the strike, enlarging its opening slightly, deepening the bolt hole, or tightening the hinges so the door stops sagging.
Can I use WD-40 on a sticking lock?
It can free a stuck lock in a pinch, but it works mainly as a cleaner and water displacer rather than a lasting lubricant, and the film it leaves can collect dust. A dry lubricant made for locks is the better choice. If a lock keeps sticking after that, the pins or the key are probably worn.
How do I thaw a frozen door lock?
Spray a lock de-icer into the keyway, or warm the key in your hand and work it in gently. Avoid hot water, which can refreeze deeper inside the cylinder, and never force the key, since that is how keys snap. Once the lock thaws, dry and lubricate it so it does not freeze again.
Can you repair smart locks and keypad deadbolts?
We handle the mechanical side: a bolt that drags or will not fully extend, loose mounting, a misaligned strike, and the backup key cylinder. Motorized bolts are especially sensitive to alignment, since a small motor cannot push past friction the way your hand can. If the electronics themselves have failed, replacement is usually more practical.
