Abstract
The present invention provides new pushbutton door locks, particularly pushbutton paddle locks, for use in controlling access through doors. The pushbutton door lock has a combination chamber which has a plurality of pushbuttons for entering an unlocking combination. An operator actuatable button and an outside paddle are provided to actuate an unlocking mechanism after the correct unlocking code has been entered into the combination chamber. The outside paddle has a single motion which unlatches the door latch and opens the door. An inside paddle may also be provided to unlatch and open the door without restricting access through the door. A hold open feature may also be provided on the inside of the door lock.
