Community Locks Light Troubleshooting

This guide explains Community lock LED light patterns and their meanings. Use the tables below to identify lock status, access issues, and hardware or programming problems.

LED Response	Meaning
Light Indicators
Green LED flashes for approximately 4 seconds	Access granted. The lock releases, and the door handle can be depressed to open the door. If the handle is not depressed while the green LED is flashing, the lock re-secures. Reinsert and remove the key to release the latch again.
12 yellow flashes over 6 seconds	A valid key was used, but the deadbolt or privacy button/switch is engaged from inside the room.
8 fast yellow flashes over 2 seconds	Access denied. A valid key was used, but entry is blocked for one of the following reasons: The door is electronically double-locked by an electronic lockout key. The resident key is inhibited, or an inhibit key was used. The key has expired based on its programmed date and time. The Master key is restricted to specific days or shift hours. The key is not authorized for the current shift or day.
2 yellow flashes	Access denied. An incorrect key was used.
1 yellow flash followed by 7 green flashes	The Master key is nearing expiration. Access is granted. This warning appears seven days before the expiration date.
1 yellow flash followed by 7 yellow flashes	The Master key is nearing expiration, but access is denied because privacy mode is enabled. This warning appears seven days before expiration.
Alternating green/red or yellow/red flashes	The lock batteries are low.
Red flashing simultaneously with green or yellow	The internal lock clock requires a reset.
Red flashes one or two times	If a key is inserted, the key was used incorrectly (upside down, backward, or not removed). If no key is used, the key switch is stuck.
Two yellow and red flashes simultaneously	The lock cannot read the lock code on the key.
No LED response	If no LEDs appear when a key is used: An invalid key shutdown is active. The key switch has failed. The lock batteries are completely depleted.
Invalid Lock and Mode Indicators

All LEDs flash four times	The lock is in Mode 0 with a circuit board fault. Use an erase key to change the lock to Mode 1, then program it using the LPI probe and terminal. Use the new key to open the door and replace the circuit board.
Two green flashes, then all LEDs flash four times	The lock is in Mode 1 and is not programmed. Program the lock using the LPI probe and terminal. Use the new key to open the door and replace the circuit board.
Two green and yellow flashes, then all LEDs flash four times	The lock is in Mode 3 with a programming chip failure. Open the door using the PPK key followed by a valid Master key. Remove the lock and replace the circuit board.
Two red flashes, then all LEDs flash four times	The lock is in Mode 4 and the storage chip is disabled. Use the PPK key followed by the Disable/Enable key to re-enable the lock.
Two yellow flashes, then all LEDs flash four times	The lock is in Mode 5 with a motor or motor switch failure. Open the door using the PPK key followed by a valid Master key. Remove and replace the lockset.
