A programming credential is only needed for the older CM locks that require a serial cable for programming. You do not need the programming credential when programming the AD-200 and CO-200 locks that use a USB cable.
NOTE: Treat the programming card as IRREPLACEABLE.
- To replace it, follow the instructions in the file folder Study Room Lock Specs for Creating a Programming Credential.
- Remove the back of the lock with a Philips head screwdriver.
- On the electronics board, press and release the INI button three times. The red LED will light up and stay on.
- Present the credential to the reader. The green and red LEDs will alternately flash indicating acceptance, then the red LED remains on. The instructions say it remains on, but I didn't find this to be the case and the procedure worked anyway.
- Press and release the INI button one time. The red LED will go out, if it was on.
- Test the programming credential with the lock by programming it.
- Repeat for all 79 locks.
