Key Duplication Service

Truly Professional St. Louis Locksmiths

Keys are notoriously easy to lose, especially if you don’t keep yours on a large key chain. To help prevent you from getting locked out of your home, office, or car, it is a good idea to have a set of spare keys made so that you have them ready to go when you need them most. In general, a basic key duplication service is relatively easy to complete, and it typically won’t take much time out of your busy day. Here’s what you need to know.

How Key Duplication Service Works


For accurate keys cut by a local professional, call Arch Locksmith.

When you need key duplication, your locksmith will utilize a machine that traces the ridges and depths of your existing key. This way, the key maker can laser cut keys that are exact copies of the originals. This same process can be applied to all types of standard keys, including:

  • House keys
  • Office keys
  • Car keys
  • Desk keys
  • Motorcycle keys
  • RV keys
  • Boat keys
  • And more.

Transponder keys, chip keys, and other high-security keys are a bit more complicated to duplicate, as they may require programming. However, you can rest assured that our expert locksmiths are up to the task. We’ll program your new key fob to interact with your car’s computer or reprogram the computer itself to accept a new key as needed.

If you have already lost your keys and don’t have a backup for us to duplicate, that’s fine too. We can read the code of your lock or de-code it or determine the key configuration so that we can make your new keys from scratch. To create keys by code, we use details from the manufacturer of the lock to get the correct bitting of the lock, as long as it has not been rekeyed since the manufacture date. If necessary, we can rekey your lock so that it takes a different key so that no one can get inside using your old keys.
