"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 questions, answered by experts

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. 

There are several situations when you should change or replace your locks to ensure your home's security. Key moments include moving into a new house, after a break-in or attempted break-in, or when a roommate or anyone else with a key moves out. It is also wise to change your locks if you lose your keys, especially if they have an address attached or you suspect they were stolen. Finally, if your locks are old, broken, worn out, or have become unreliable, they should be replaced.

Thieves can open almost anything with enough time and the right tools, but they also prefer easy targets that are unlikely to get them caught. Forcing open gates is loud and difficult, and to be able to open one electronically requires extensive knowledge of the system, which most thieves don't have. Electric and other security gates are great deterrents because the thief will move to an easier target. If the thief is determined to enter your property, they will most likely find a different entrance point.

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. 

Commercial locksmith services range from $75 to $500, depending on the job's complexity, such as key duplication, lock installation, or access control system setup.
