Electronic locks can provide improved security over mechanical locks. Despite the improved security of electronic locks, there may be occasions where it is desirable to replace the electronic lock. Replacing an electronic lock can be expensive and challenging, particularly if the electronic lock is being replaced by a different electronic lock produced by a different manufacturer. The present disclosure relates to an electronic lock with a replaceable lock core that enables replacing the electronic lock core with a new electronic lock core without needing to replace the entire electronic lock. Further, through use of access controls managed by the electronic lock and electronic key combination, and the unique mechanical configurations disclosed herein, it is possible to replace an electronic lock core without compromising security of a device or location secured by the electronic lock.

An interchangeable cylinder lock core with a mechanism for transferring a torque to a lock unit when a key plug is rotated. The interchangeable cylinder lock core includes a shell having an upper part, provided with a central row of locking pins in associated cavities, and a lower part with a cylindrical bore accommodating the rotatable key plug. At least a part of the cylindrical bore extends through a rotatable retainer sleeve. A back region of the key plug has a minimum length with the adjoining front region of the key plug being located in front of the mechanism for transferring torque. The adjoining front region accommodates, in addition to the central row of locking pins, at least one side locking mechanism which is located in its entirety within the front region of the key plug and interacts with at least one recess in a fixed front end sleeve portion.

A programmable combination lock with keyed lock override is disclosed. The lock employs a stack of rings and dial wheels, with a mechanism for coupling and decoupling the rings and dial wheels. A user can program a custom code by unlocking the combination and rotating the inner and outer dial wheels until the desired code is indicated, and then locking the combination lock to set the code. A keyed lock with a master key couples to the combination lock and can override a combination lock in the locked state. The keyed lock allows multiple keys to lock and unlock the combination lock. In the event that a user loses the master key, the user can use the second key to create a new lock combination to operate the lock, yet render the lost master key inoperable.
