Does the keypad display show an 'open lock' icon after you enter your combination?

If not, then you will need to ensure you are using the original factory code if the batteries have been removed.

Also ensure you insert the key into the keyhole first and turn it to release the cylinder inside, then enter your combination.

Sometimes you may need to apply extra pressure to the left side of the door to open it after entering your combination.

Also ensure that the handle is in the horizontal position before attempting to enter your combo and open it.

Reply back and let me know if that works?
