How do I update the master code on my VAULTEK VS10 safe?

[DiCollin]

To enhance the security of your VAULTEK VS10 safe, changing the master code is a straightforward process. Here's how to do it: First, ensure the safe is unlocked and open. Locate the "PROGRAM" button and press and hold it for approximately three seconds. You'll know you've done this correctly when all the keys (1-5) on the keypad illuminate in red. Release the "PROGRAM" button. Next, use the numeric keypad to enter your new desired master code. After entering your new code, press and hold the "PROGRAM" button again for three seconds until the keys light up red again, then release. Re-enter your new master code a second time to confirm it. Finally, press and hold the "PROGRAM" button one last time for three seconds. The safe will beep, and the keypad will flash green, indicating that your new master code has been successfully programmed. Always test your new master code immediately to verify it works correctly.
