The SnapSafe GlideVault Hand Gun Safe 75404 has a pry-resistant door to keep children and unauthorized users from gaining access. If you don't want to anchor this safe down, you can use the provided 5-foot cable to secure it to a solid surface. To gain access to your items inside, you can enter your own personal 4–6-digit combination to get in. If someone is trying to guess the combination and they enter an incorrect code 5 times, the safe will beep and lock them out for 5 minutes. The tones on the safe can be silenced so that when you are trying to access your handgun in an emergency, you won't make a sound. There is an override key in case the batteries die (4 AAA Batteries) or you forget your combination. A backup USB port allows for backup access when the batteries are dead.
