 Can not lock Sentry safe

I have a 300 lb Sentry G5343 safe with an electronic lock and I recently moved it. After I moved it, it would not open so I kept putting in the code and jiggling the handle until I was able to pull the lever to the left and open the safe. After that I could not lock the safe, I have tried putting the code in when the lever is in the locked position (down) and moving the handle in various positions. Still, the lever will not lock and just open and closes without putting in any code. Anybody have experience with this?

How old are the batteries?

Good question, I think the batteries are about 3 years old. I will try to replace them and see if it will lock. Although, the low battery light is not on.

Try replacing the battery and you may have to reset codes, good time to check out instructions inside the safe or on the website before you have to close it. Its worth it to change the batteries yearly,cheap insurance.

I replaced the batteries but still nothing, have not reset the codes yet; tried the factory code and my personal code and around with it some opening and shutting in, punching in the code and opening and closing but it still will not close

Not sure if it's the same design, but I have a smaller Sentry Safe that came with a set of keys. My electronic lock did somewhat the same thing and I couldn't get it to work, so I had to break out the keys, take the keypad and battery pack out and recode it. Do you have keys for it?

I can not find the skeleton keys to this safe unfortunately, will keep looking.

I talked with the Sentry customer service and a technician and they told me that I might need to replace a solenoid, pictured below as the black rectangular thing for about $50. He asked me to send him pictures but has not gotten back to me. Assuming it is the solenoid, should I replace it or hire a locksmith to see if he can fix it?

Can anybody see what the problem is? I have it in both the locked and unlocked position from the back in the pictures.

A solenoid would make sense as it would do the actual mechanical work of retracting the locking bolts once the electronics recognized your combination. Or vice versa, it would extend the locking bolts in place when closing the safe up.
There might be a way to check the solenoid with a multi-tester but that's beyond my capabilities.

does it have a security key like mine does? It will not relock or unlock if the button is pushed in.

I had one like that. Mine had a key by-pass. I grabbed a hammer and chisel, in a rage, and tore off the electric lock.

I use the thing to store mags and ammo now and keep the safe key..........................................nunya B

You mean this button right here? Does it need to go down? I can't find the skeleton keys and Sentry wants like $15 plus like a notarized letter or something for replacements, great customer service. Anyways, would there be any way to make that go down without the key? What if I took off the solenoid?

That is not exactly what I am talking about. If it is like the one I have it has a round spring loaded key slot that provides an extra lock next to the digital key pad. If that cylinder on the front of the safe where the key fits into is pushed in the safe will not relock or even open if closed.

I fixed the problem with help from Sentry tech support. Turns out the bracket on top of the solenoid (the black box) was stuck, there is a pin that retracts from the solenoid to lock the bracket in place and this keeps the safe closed. Fix was putting a flat head screw driver between the bracket and the solenoid and the bracket was able to retract back. In the picture below the arrow is pointing to where I put the flat head to make the bracket move to the right.
