To reset the lock to factory default, see the following:
Reset Lock to Factory Default
The following procedure returns the lock to its factory defaults
by deleting all user codes (including the Master PIN code*) and
returning all programming features to their original default settings
(see below).
1. Remove the batteries and then remove the inside escutcheon
to access the reset button.
2. The reset button (see image at right) is located above the
PCB cable connector.
3. Hold down the reset button for a minimum of 3 seconds and
then reinstall the batteries; once the batteries are properly
installed, release the reset button.
All features (including adjustable settings** (see below) should
now be returned to factory default.
Upon reset, Master Code Registration is the only option available
and must be performed prior to any other programming of the lock.
See "Operation" later in this manual for programming instructions.
