The keypad twists freely and does not re-lock my safe.
The Yellow, Blue or Black tab is out of alignment with the metal notched baseplate. The spindle may be putting pressure on the lock body not allowing the solenoid to fire. Mechanical problem with the lock body.
Pull your tab releasing the dial part of the keypad and pull out. Use an ice pick and try to align the metal notched baseplate with the plastic channel at the top of the keypad. Remove the keypad and examine the spindle length making sure that there is not pressure getting exerted on the lock body.
Note: A locksmith is recommended to perform this action. Contact the safe manufacture or a safe and vault technician for further assistance.
