Well i have a sentinel safe and cant open it. The key rotates quarter of the cycle and then stops. A the key is turned It feels as if the (5 cylinder) mechanismit is hitting on something solid inside and the key stops dead. Any idea? Thanks!

Why don't you know the digital combination? You must be opening it every day if your medication is in there.

Call a mobile locksmith. Tell them it is an electronic lock and ask if they have a rare earth puck magnet? They will use the magnet to draw back the electronic bolt.

Call a lock smith.

notify sentinel

If it is electronic, you can open it with a rare earth magnet.

open sentinel safe with magnet

If it is a traditional dial, you will need to contact sentinel, with the serial number, a cheque for $25 and a sworn affidavit that the safe is yours.

In cases where you think you can't remember a combination, it should be kept in your wallet and perhaps coded, add one number or 2 numbers to each of the numbers in the real combination.

Contact Sentinel directly to inquire.

Counter clockwise 3 full turns then clockwise to the first number.

Make sure that the key barrel is all the way out. Then replace this example code with your factory code and try it
Example combination: 70-55-05

1. Do two rotations to the left stopping at 0.

1. Do two rotations to the left (Anti-clockwise) on the third time past 0 go to your first number.

So – 0 to 0, 0 to 0, 0 to 70

1. Do one rotation to the right (clockwise) on the second time round stop at your second number.

So – 70 to 70, 70 to 55

1. Turn directly from your second number to your third number heading to the left.

So – 55 to 05

1. Push down the handle.

The operating instructions on the ES20 as per the crappy manual:

Open safe using emergency key provided

Insert batteries in the box inside the door

Opening the safe
a. pre-set factory code 159
b. input 159 (the yellow light will flash and the buzzer will beep), then press B or A button, the green light will be on, rotate the knob clockwise, pull outwards, the door is opened

Closing the safe: close the door, input the code (the green light will flash for 5 secs). Turn the knob anti clockwise, the control system will activate and the safe will be locked

Changing the code: open the safe, press the red button located inside the door, the yellow light will go on indicating the code can be changed. Input the new code (1-8 digits), then press A or B button, it shall be confirmed by two beeps indicating the new code has been accepted and stored. If the yellow light and buzzer beeps 3 times the code is invalid - try again

Emergency Key - store in secure place NOT inside the safe. Remove the override cover in the centre of the face of Safe (its a silver plastic panel with Sandleford Electronic Safe ES20 on it), insert override key (a cyclinder key) - hidden underneath the override cover panel - and turn anti clockwise, rotate the knob clockwise to open door

Changing the Battery - If the red and green light are on this indicates that the batteries are low and require changing. To ensure the batteries have been installed correctly test before closing the door
