I forgot my combination i tried putting a couple different numbers in after three trys the key pad locked and now when i type any numbers in it doesnt work. how do i unlock my safe?
ANSWER : After 3 trys the keypad does go into lockout mode but it should only last for about 15 minutes and then let you retry 3 more codes to try and open. if you still do not know what the combo is you can usually call the maker of the safe and with the serial number you might be able to get the original combo that the safe was set to when it was purchased ( this is a factory set combo ) — now if that does not work, your next step will be to call a safe tech ( locksmith ) to set up a auto dialer,, this takes about a full 24 hours to get the combo right. the safe tech can also drill a small hole behind the dial and manually remove the locking bolt. after the safe is opened the locksmith will fill the hole and reset the combo for you ( also replace the battery at this time too ).
