Description

This procedure explains how to perform a hard reset on an E-Plex 3xxx Series lock when the Master Code is known. The reset process uses the mechanical override key and the Master Code to return the lock to an unprogrammed state.

Resolution

Follow the steps below to perform a hard reset using a known Master Code.

1. Insert the mechanical override key and turn it to the 3 o’clock position.
2. Press the # key, then turn the key back to the 12 o’clock position within 5 seconds.

3. You have up to 5 seconds to press # and return the key to the 12 o’clock position.

   • If the 5-second timeout expires without pressing #, the lock continues normal operation.
   • When # is pressed, the lock exits its current state.
   • If any other key is pressed or the timeout expires after pressing #, the lock exits the reset sequence and remains in the access state.
   • If the sequence completes successfully within 5 seconds, the lock enters the Reset Sequence State.

   In this state, the lock displays a Reset Sequence In Progress indication by alternating green and red LED flashes once every second.

4. Once in the Reset Sequence State, the lock provides a 20-second window to enter the Master Code.
   • If the correct Master Code is entered within 20 seconds, the lock performs a hard reset and returns to an unprogrammed state.
   • If an incorrect Master Code is entered, the lock exits the Reset Sequence State and returns to the access state. The Tamper Count decrements.
   • After four consecutive incorrect Master Code attempts, the lock enters the Tamper Shutdown state for 30 seconds. Normal operation resumes after this delay.
   • If no Master Code is entered during the 20-second window, the lock assumes the Master Code is unknown and enters a 15-minute wait period.

Note: The M-Unit is only applicable when using optional E-Plex software.
