Question edited for clarity.
Although this guy makes it look hard work, they will usually bounce open quicker that this. You can also bang the top with a rubber mallet, or use a rare earth puck magnet to pull the actuator bolt.
If your Sentry Supreme 5330 safe is not opening, there could be a few possible reasons why:
Combination Error: If you are using a combination to open the safe, make sure that you are entering the correct combination. If you have forgotten the combination, you will need to contact Sentry Safe customer service to get assistance on how to recover or reset your combination.
Dead Batteries: If you have an electronic lock on your safe, the batteries may be dead. Replace the batteries and try again.
Jammed Bolts: The locking bolts may be jammed due to incorrect operation or a mechanical problem. Try tapping the safe door gently with a rubber mallet to loosen the bolts and then try to open it.
Mechanical Malfunction: If the safe still does not open, there may be a mechanical malfunction. In this case, you will need to contact a professional safe technician to diagnose and repair the problem.
Note: If you have lost your key, you will need to contact Sentry Safe customer service to order a replacement key.
The sound does two things
It lets you know you have done a positive button push.
It beeps when the battery is low to alert you to change them and save you having to cut the back off the safe.
It isn't programmable, snip the wire to the sounder, but it is likely hard soldered to the main board.
