# Reset a Cleo lock using the Reset Key

All Cleo locks must be registered to a Flex Key for electronic key operation/management. If the programming needs to be erased at any time, the locks can be reset with a Cleo Reset Key.

The Cleo Reset Key is a support tool that can be ordered from Digilock after troubleshooting with [Digilock Support](https://www.digilock.com/contact/support/). It should be kept in a secure place when not in use. In the event that the key is lost or stolen, it is designed to expire 3 weeks from the ship date. Once the key expires, it can no longer be used.

1. Identify locks to be reset and insert the Reset Key into the key slot. A click will be heard.
