Abstract: A lock including a housing and an opening for receiving a locking bolt moveable between a locked position and an unlocked position is provided. The lock also includes a rotary actuator having a rotary output of a predetermined amount and responsive to entry of an electronic combination input by a user; a cam wheel operably coupled to the housing and responsive to a manual combination input of the user, the cam wheel including a cam way; a bolt release lever moveably coupled to the housing and including a nose portion engageable with the cam way and a locking bar; and an armature post responsive to both the rotary and manual inputs, the armature post moveable between a blocking position for blocking the locking bolt in the locked position and an unblocking position for allowing the locking bolt to move into the unlocked position.

Abstract: A lock having a housing defining a cavity with first and second opposing side walls and an opening for receiving a locking bolt, the locking bolt moveable between a locked position and an unlocked position is provided. The lock includes a rotary actuator having a rotary output and responsive to entry of an electronic combination input by a user; and a sliding blocking mechanism responsive to said rotary output and moveable between a blocking position for blocking the locking bolt in the locked position and an unblocking position for allowing the locking bolt to move into the unlocked position.

Abstract: A lock including a housing having an opening for a locking bolt, a locking bolt movable between a locked position and an unlocked position, an actuator positioned within the housing, and a rotary blocking device that prevents the locking bolt from moving to the unlocked position. The lock may optionally include a tamper resistant mechanism that is designed such that attempting to forcibly move the locking bolt from the locked position to the unlocked position while the actuator remains in the locked condition causes the locking bolt to engage the tamper resistant mechanism.

Abstract: A method of automatically activating a user code for an electronic lock having a keypad entry system is provided. The method includes providing an electronic lock having a keypad, the lock including a factory-set service code and a factory-activated default user code. During installation, the factory-set service code is entered into the keypad and the lock confirms that the entered factory-set service code is valid. The default service code is changed by entering a new service code. When the lock confirms that the new service code is a valid service code, the factory activated user code is automatically activated.
