The basics of choosing the right lock for your gun safe are pretty simple. The first rule is that your gun safe should not have a lock that uses a key. Typically, when you find a key lock on a gun safe if you really are not looking at a gun safe but a gun cabinet. Your gun safe is going to have a more secure locking mechanism than a key lock.
The main types of locks for gun safes are combination locks and electronic locks. Biometric locks are showing up some. There are also locks that combine standard combination locks and electronic locks.
This video discusses digital locks vs mechanical combination locks.
Combination locks provide tried and tested security. The combination locks have been around for years and have not changed that much because they just work. If you choose a good combination lock you can be assured your safe lock will be secure.
One of the main practices you need to follow with a combination lock it to be sure to spin the dial after closing the door. This way your lock mechanism actually locks. If you do not spin the dial the lock will not actually be engaged and the door can be opened.
