# No LED response when hand is presented to RFID lock

There are two primary reasons that may cause an RFID lock to become unresponsive.

### Deadbolt, Deadlatch, and Cam locks

The batteries may need to be replaced. For immediate access, operate with a valid Manager Key.

- For Shared Use override instructions, go to [Override a Shared Use lock with a Manager Key](/v1/docs/how-to-override-an-rfid-lock#override-with-a-manager-credential).
- For Assigned Use override instructions, go to [Override an Assigned Use lock with a Manager Key](https://digilock.us.document360.io/docs/how-to-override-an-rfid-lock#override-with-a-manager-key).

### Deadbolt and Deadlatch locks

The front unit may not be properly connected to the rear unit. Remove the RFID lock from the door and check the connection.

A solid, motor-driven bolt that extends into the locker frame.

A spring-loaded bolt that automatically secures when the door closes. It requires a valid credential to open but doesn’t need manual locking.

A rotating metal piece that engages or disengages the lock when turned. Locks with a Cam have a knob or handle to manually rotate the mechanism.

Note: A flat cam is shown for illustrative purposes.

- Overrides user access
- Allows management inspection
- Provides external power
- Sets lock functionality if applicable (lock must be a keypad with a Deadbolt)

Placing your hand near the RFID reader will make **the LED flash red**.

Shared Use is perfect for environments where multiple users need temporary access. An RFID credential allows anyone to use the unit, and once unlocked it's available for the next user. Locks configured in Shared Use may feature either a deadbolt or cam locking mechanism.

Placing your hand near the RFID reader will make the LED flash green.

Assigned Use is ideal for personal or dedicated access, where a specific individual or group is given an RFID credential to open a designated unit. The unit remains locked until the assigned user unlocks it using their credential. Assigned Use locks can be configured with a deadbolt, deadlatch, or cam.
