Locksmiths questions, answered by experts

Many local hardware stores have the equipment to copy basic keys at a low cost. Some locations may have freestanding machines where you can pick out a blank and insert it and your original key into the duplicating machine.

There are many types of deadbolts, but these tips work on most. First, address any grime buildup. A bit of WD-40 will loose up rust and dirt so the deadbolt can turn. Inspect the door and frame alignment if this doesn't resolve the issue. Adjust the strike plate or the deadbolt's position to improve alignment. If the problem persists, disassemble the lock to inspect for damaged or worn parts. If you are unsure how to do it, hire a local locksmith.

When the temps drop, sometimes you need to thaw a lock to regain access. Options include warming the key with warm water, applying a de-icing spray, or using a hair dryer on low heat. Avoid using boiling water to prevent damage. To prevent future freezing, consider installing a cover or shield over the lock to keep water and ice out. Remember to be patient and gentle during thawing to avoid damaging the lock or key. If all else fails, consult a professional locksmith.

Lock bumping is a technique locksmiths use to quickly and quietly open a pin tumbler lock, typically found in most types of deadbolts. It involves inserting a specially crafted key, or bump key, into the lock and tapping or "bumping" it with a mallet or similar tool. The force applied causes the lock's pins to jump momentarily, allowing the lock to be turned and opened. Unfortunately, thieves also use this technique to break into homes. Luckily, products like a deadbolt strap will fortify your lock.

It’s best to avoid using oil-based lubricants within a lock because they attract larger amounts of dust and debris. When this occurs, it can make it harder for you to operate the lock, or it can even cause damage to the internal locking mechanism. A dry lubricant is the ideal solution instead.
