Q: What lock should I select for a wall safe?

A: This can be personal preference. There are many different lock types including key lock, dial combination lock, digital lock, and even biometric locks. A key lock is easy to use but a key may get lost which can be a security risk. The dial combination lock is the most reliable, but you will not be able to change the combination yourself without a locksmith. The digital lock is the most convenient, but you will need to change batteries about once a year. A biometric lock will give you quick access. You also do not need to worry about anyone else having your fingerprint. Biometrics are still pretty new technology, so they are not always 100% reliable.
