There is no "default code", but they do keep the serial number and code on file, for just this purpose.

3 Digit Combination Lock

  1. NOTE: If your safe DOES NOT have a key, skip Step 3.
  2. Turn the dial to zero.
  3. Insert your key and turn it until the plunger pops out.
  4. Turn the dial to the left (counterclockwise) three times to the first number of the combination (pass the first number of your combination two times, stopping on it the third time).
  5. Turn the dial to the right (clockwise) two times to the second number of the combination (pass your second number once, stopping on it the second time).
  6. Turn the dial to the left to the last number (stop the first time on your last number).
  7. Pull the handle down; the door should open.
If this still does not open the safe, refer to the following page for additional different types of Sentry Safe models:

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

If you repeatedly get an error code when entering your combination I would first ask if your batteries recently went all the way dead ? If yes then possible that the data for your combination was lost. In your user manual for your safe is a factory code for your safe. If you did not change your factory code when you set up your safe then this will work to get you into your safe. If you did change the factory code and do mot have that number either then the only way to get into your safe is to contact Sentry Safe customer ssrvice. They will be able to take care of you but it is a process.

There is a lock and there is a latch.
You can latch the safe without locking it and unlocking it does not unlatch it.

After you unlock it, then you must press up on the spring loaded latch while (this important) pressing down on the cover to releast the pressure on the latch hook, allowing it to move out of the way. After the latching hook is out of the way, you can release the pressure on the lid and it will open. You can't see the latch hook as it drops down from the lid, into the front wall of the safe where it engages a post, but perhaps you can imagine what it looks like.

Mine will not unlatch, even though it is unlocked, unless I press down on the lid to give it clearance first. There is quite a bit of spring in the plastic that this safe is constructed out of. It works against you when you try to open it and close it.

I can take digital photos of the mechanism if this description does not help.

If you know the combination:

1) Turn the dial to the left a few complete rounds, then stop on 1st number.
2) Turning the dial to the right, pass up the 2nd number once, then stop on it on the next round.
3) Turn the dial to the left directly to the 3rd number then stop.

The handle should open now.

If you have lost the instructions that came with the safe, you may have to call a lock smith.

If there is a reset combination it's unlikely anyone is going to tell you otherwise you would have free access to any other locked Sentry safe. A locksmith who deals with the brand or Sentry themselves will probably be able to do it for you if it's possible.
