My Sentry 3150 safe is closed and locked and the lock/dial is stuck. The dial only turns between 20 and 25.

Remove the screw from the backside of the door.

Hello,

I am a Safe Specialist i have been reading some of your problems and this should help there is no code if you have lost yours only the default code for the model 1610 the default code is: 77,22,09,11,64 try that if you havent changed it and with this problem with people not getting the handle open with the green light happening i suspect this is a issue with the lock mechanism i have had many of the same problems with people bringing them in when you get you safe open it and where the lock is put some lubricate on the lock regulary as the lock sticks and wont open if you havent done this then you cannot get it open see you local safe specialist and tell them what i have said and they may or may not be able to get your safe open i hope this has helped Rob Safe Specialist World.

go around 3 times to the left
stop at the 1st number
go to the left one full time and pass the # but stop at the 2nd #
go to the right and stop at the 3rd # the 1st time you come to it

I just bought one last night

I finally ignored the poorly-written instructions for programming a personal code and simply entered the factory code first and then pressed the prog/enter code button.  The safe opened.  The instructions tell you to push the prog/enter code first and then enter the factory code or personal code to open the safe.  Wrong!  Do it my way should this problem happen to you.

no if you turn your lock box around so your key is facing away from you and place your right hand on the side top and your left hand on the box and push the lid to the right a good inch and a half and lift the box will open no problem key or no key. this is a very poorly made safe
