"Very well, the locksmith arrived n time and got to work right away in replacing the locking system. He then took the time to show me how to adjust the door in the future so it would not stick as the house moved. An absolute must if you need a locksmith."

Locksmiths FAQs, answered by experts

Standard residential deadbolt locks come with a steel bolt that locks your door into place using a key (or keypad) on one side and a thumb turn on the other. When you lock it, the bolt slides into a strike plate on your door jamb to secure your door shut.

If you don’t have your original key, the easiest way to obtain a copy is to call a locksmith. For house keys, your locksmith has several options for configuring a new key: 

  • They can input a lock’s identification code into a database to obtain key-cutting instructions.

  • They could analyze the lock cylinder to determine how to cut a new key.

  • They can create an impression of the lock cylinder from which to cut a new key. 

Using a combination of tools (often store-bought plumbing tools) and brute force, a burglar can easily snap the lock on a door. Snapping a lock aims to gain access to the cylinder inside, which holds the locking mechanism. Once the thief snaps the lock, they can pick the cylinder open and walk right in.

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.

It’s possible, but depends on the design of your lock. Some door locks that lack a keyhole do boast a small hole on the exterior handle or knob. This hole’s primary function is to allow water to drain out of the lock, in addition to giving homeowners an easy spot to insert lubrication. However, you can typically use a paperclip in this pinhole to unlock the door by manipulating the mechanism inside.
