Common Door Key Service Questions

When you take a key to a hardware store or a locksmith for copying, you can expect the key-cutting process to take as little as 30 seconds. The key copier will review your current key to decide on the correct blank. Then, your original key and the blank are inserted into a key duplication machine to cut an exact key copy. When it’s all said and done, you can have a new key in your hand in just a couple of minutes.

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.
