Abstract
A door handle assembly that allows for easy removal and switching of handles is disclosed. Such an arrangement may provide the flexibility to change handle orientation and interchange handles based on a user's circumstances or preferences such as when a door handle is configured as a lever having a curved shape. Further, the door handle may be configured as a door lock having a keypad access control. The face of the keypad accessible from outside the door may include auxiliary battery terminals to provide the user with easy accessibility for providing temporary power to the door lock with an auxiliary battery should the installed batteries housed within the door lock fail to provide sufficient power.
