Lock Repair in Radnor, PA

A deadbolt that drags against the strike may be meeting the opening at the wrong angle.

In Radnor, a shifted door or changes in weather can put those parts out of line. You may feel resistance when you turn the key, or find that the latch no longer catches. Wear inside the mechanism or a loose part can also make a knob spin or a lock stick. Forcing it can bend the key or make the problem harder to assess.

You can check whether the door closes evenly and whether the bolt moves freely with the door open. If the bolt moves easily when open but drags when closed, alignment may be the issue. Stop if you feel strong resistance rather than forcing the turn. We repair house and building locks in Radnor by identifying what is causing the trouble and addressing the affected parts. If wear is limited, a repair may restore operation. If damaged parts cannot be repaired, replacement may be the better choice.

We look at how your deadbolt meets the strike and whether the door sits squarely in its opening.

If the bolt rubs as you turn it, we check for movement in the opening, loose hardware and wear inside the lock. Weather can change how the opening fits, while a loose part or worn mechanism can feel like an alignment problem. We explain what we found before starting work, including any issue outside the lock repair itself.

You may have a choice between adjusting the strike, repairing a worn part or replacing the lock. We explain what each option addresses and whether an adjustment alone is likely to leave another problem unresolved. If the door needs work beyond the lock hardware, we point that out so you can decide how to proceed. After the repair, we check the deadbolt with the door open and closed, then have you try the key and the inside turn to see how they feel.

A storm can leave moisture and grit around a repaired lock. Wipe exposed surfaces with a soft, dry cloth, and keep the area clear of dirt.

Avoid household oil or a spray lubricant unless the manufacturer recommends it, since the wrong product can collect debris. Use a clean, undamaged key, and do not force it if it begins to resist.

Watch how the door closes. Dragging against the frame, needing a shove to close, or a latch that misses its opening may point to shifting or swelling. A knob that spins or a key that turns hard is also worth another look. Call us again if any of these problems return, or if the lock will not hold securely. We can check whether the trouble is in the hardware or in the way the door sits.
