How do I change the combination on SENPL048E sentry portable security safe

Open your Sentry safe by typing the five-digit factory code (found in your owner's manual) on the keypad. It's always a good idea to change your combination while the safe is open, so that you don't inadvertently lock yourself out.
  • Delete any existing codes by pressing the "P" key and entering the factory code, followed by "00000." On older safes, press the "PROG" key and entering your factory code twice to delete old codes.
  • Press the "PROG" or "P" key again on your Sentry safe's keypad.
  • Enter your safe's five-digit factory code.
  • Enter a five-digit code of your choosing within 5 seconds. This is your user code. While the factory code cannot be changed, your user code can be changed as often as you like, and that should be your primary code to open the safe. Only you should know your safe's factory code.

    I need to reset my combination to my mesa safe

    This safe was shipped with a factory Master Code of 1-2-3-4-5-6-7-8.

    If you changed the Master Code you will need to use the code you changed it to.

    Deleting your current User Codes:
    Input * - * lock will beep twice
    input 6-6-6-# lock will beep twice
    Input current Master Code - # lock will beep twice
    Input user number - # lock will beep twice (not user code, user number is which user number you want to delete 1,2,3,4 or 5)
    Re-input user number - # light stays green for 3 seconds

    Example: * - * - 6 - 6 - 6 - # Master Code - # - 5 - # - 5 #
    This will delete user 5
    Unsuccessful code change: five beeps, repeat the steps.

    Changing User Codes: Code length can be 3 to 8 digits long
    Input * - * lock will beep twice
    Input 4 - 4 - 4 - # lock will beep twice
    Input Current User Code - # lock will beep twice
    Input User Number - #
    Input New User Code - # lock will beep twice
    Re-input New User Code - # light stays green for 3 seconds

    Example: * - * - 3 - 3 - 3 -# - User Code 2 - # - 2 - # -New User Code - # - New User Code - #

    That example will change user code 2.
    Unsuccessful Code Change: five beeps, repeat the steps.

    There are other things you can do with the MSL-500 lock that comes on the MFL-2014E. You can change the master code, activate user codes, change user codes, delete user codes, set single user or dual user modes (dual user modes requires two user codes to be entered each time you want to open the safe, set the time delay.

    The Mesa safe company has a website which does have the operating instructions for the MSL-500 electronic lock. A Google search of "Mesa MSL-500 Operating Instructions" would get you there quickly.

    I need to change the code on the safe

    Safe? You are aware that this got posted under "Cars & Trucks"? I think you will get a better answer if you post your question under the correct heading and provide a lot more information like WHAT KIND of safe are you trying to change the code on? I am an automotive technician, not a safe-cracker, but I can tell you that if I was, I would want to know what make and model of safe I was trying to crack (or change the code on).

    I have a Dell Inspiron 9300 with a blank screen; it only comes up in VGA or safe mode. I received the error message 1000-0146 after running the diagnostics. We have tried looking for the LCD panel switch...

    That error code is pointing on your hard drive-it is going in Big Junkyard in Heaven. Try recovery console if you have original installation CD. If not,your need to take out stuff that your need and install another hard drive. Good luck and Happy Holidays!

    Locksmiths agree the factory code is burnt into memory and can not be erased. When you buy a sentry safe you have to set a user code to give out as that code can be changed. program instructions
