An impression key is used during the impressioning process to create a key for a lock.
Impressioning is generally used when the original key is no longer available to make a duplicate.
To complete this process, a locksmith requires the lock in question and a blank key.
From there, the following steps are taken:
- A file or code machine is used to prepare the impression key, which is then inserted into the keyhole of the lock.
- The key is then gently moved around so that the pins leave small markings on the key.
- A locksmith then files each marking or impression, ensuring the pins of the lock interact with the new key so that it is able to turn.
- The depth of each groove is determined before a new key is cut according to factory specifications.
If this new key works, a locksmith can make duplicates so that you don’t run into this issue again.
A locksmith is able to impression in a key in about 10 minutes if you are dealing with a professional that is.
It is possible to purchase an impressioning kit and attempt this process yourself, but it’s not recommended if you don’t have the experience.
