Overview

Only the CM locks (the oldest locks) require a programming credential.

  • You need this credential every time you program the locks. 
  • You use the credential while the serial cable is plugged into the lock and you are holding the HHD.

  • Currently the programming credential is a key fob. It is easier to use than a key card because of the location and size of the credential reader.

  • You do not need the credential when collecting audit data from the locks, but it's good to bring it anyway in case you need to program the date/time for the lock.

Creating a new programming credential

Creating a new credential is not difficult, but it is tedious and time-consuming. For this reason, treat the programming credential with care. 

  • Remove the back of the lock just like you do when replacing batteries. 
    • take care to keep track of the screws and, if it pops off, the spring.
    • Be careful not to close the door to the room at this point. If you do, the only way to leave is to reassemble the lock.
  • On the electronics board, you will see two small, silver buttons next to each other. 
    • The button on the left is labeled CLR (you have to look closely).
    • The button on the right is labeled INI. This is the button you want.
  • Press the INI button (the one on the right) three times.
    • The red LED light on the front of the lock will light up and stay lit.
  • Present the new programming credential to the reader.
    • The green and red LED lights will alternately flash once the credential reader accepts the new credential.
    • Be patient. Depending on how old the batteries are, it may take a moment or two for the credential reader to accept the new credential.
  • Press and release the INI button one time.
  • Test the programming credential with the lock by programming the lock.
  • Replace the back to the lock.
  • Repeat for the remaining doors.
