Digital and electronic safes are easy to use and provide an extra level of protection over typical key locks. Where a burglar attempting to break into a safe with a key lock might get lucky and find the key – or even pick the lock – he has little chance with an electronic lock. There's no key for him to find, no keyhole to pick, and no chance of him correctly guessing the right combination from the thousands available. Some electronic locks also feature time delays, audit trails and multi-user support, perfect in a business setting. Biometric fingerprint locks are also available on some safes.
