For gun owners, accessibility is a major concern, especially in households with children. Gun owners need to have the ability to quickly access their firearms in the event of an emergency but need also need a high level of security at all other times. In the event of a home invasion, fumbling to open a combination lock on a gun safe is less than ideal.
For gun owners looking for expedient access and impenetrable security, a biometric mechanism is likely the best option. Unfortunately, however, biometric tech is still in its infancy, leaving the market is flooded with cheap and unreliable biometric gun safes. Due to the added cost of this technology, many of the higher-end gun safe manufacturers elect not to feature the biometric lock as an option for their safes. Although the best biometric gun safe locks may offer ideal accessibility, until the technology matures, a standard digital keypad lock is probably the best access option for a gun owner.
