You can open them faster with a rare earth puck magnet that you can putting the combination digits in.

There are also this type of attack but the Lock Picking Lawyer shows the workings. The magnet pulls the solenoid in the same way. It is a low skill attack.

Classic mistake keeping the emergency key inside the safe!
It can be opened very easily in 10 seconds with a large rare earth puck magnet in a sock. They all work the same way using an electronic magnetic solenoid operated by the internal battery. The puck magnet does it externally.

Look at the YouTube channel 'The Lock Picking Lawyer'. All his videos are short and sweet. All combination locks can be decoded with a feeler gauge or a thin piece of plastic. He will have opened this lock.
Well you put the code in and it opens.
I guess you missed of the part where you ignored the 'Change Battery' notifications and the incessant beeping :>D Or has it just failed, found it in a skip, found it in a house, code written on the back?
You can open it faster with a rare earth puck magnet than you can inputting the code. The word ;Safe; is a misnomer.

Simple programmable Electronic Lock with buzzer and LED. 3 to 8 numbers ... NOTE: This safe stores up to 2 passcodes (a user code and a manager code).
If your Delsey combo lock won't lock, there are a few things you can try to troubleshoot the issue:
Check the battery: Make sure the battery in the lock is not dead. If the battery is low, replace it with a new one.
Check the lock's alignment: Make sure that the lock is properly aligned with the suitcase zipper. Sometimes the lock may be slightly off-center, which can prevent it from locking properly.
Check the lock's mechanism: Make sure that the lock's mechanism is not jammed or damaged. If it is, it may need to be repaired or replaced.
Check the lock's code: Make sure you have entered the correct code for the lock. If you have forgotten the code, you may need to reset the lock or contact the manufacturer for assistance.
Clean the lock: Sometimes dirt and debris can accumulate in the lock mechanism, preventing it from functioning properly. Clean the lock with a soft cloth and mild soap.
Check the suitcase: Make sure the suitcase is not damaged in any way that can prevent the lock from closing properly.
If none of these solutions work, it may be best to contact Delsey customer service for further assistance. They may be able to provide additional troubleshooting steps or may suggest to get the lock serviced.
Put gentle pressure on the catch and starting with the combination wheel that is furthest away, turn the dials until you feel it give a little, then move onto the next dial. The final dial will drop into place and open.
There is also a 'shimming' technique, where you insert a thin feeler gauge leaf into the dials and feel for the flat spot. Then you turn all the dials together until the lock pops.

Apparently when you got the safe, you also got an emergency key for it as well, just in case you forgot the combination. The key also permits you to reprogram the safe. Where might the key be? --Perhaps with the documentation for the safe or a safety deposit box or gun maintenance materials. It is anybody's guess where you hid the key. You otherwise will have a difficult time opening the safe on your own. You may need a referral to a locksmith but here is the phone number to the technical services of Winchester Safes: Technical Service at 877-948-6723.
