When in the Zkteco ZK-AL10DB and ZK-AL20DB smart locks we have registered users (either with PIN, card, and/or fingerprint) and these users do not have access permits (the terminal shows an error message), it is usually due to the position of the "Lockout switch":
- Red: Only administrator users will be granted access, while "normal" users will not
- Green: All users will have access
