⚠️ Note on Model Applicability: The Wi-Fi board cable design described in this article — and the drill-out risk associated with it — primarily applies to the LZ-D (Deadbolt) and LZ-I (Interconnected) models. The Wi-Fi communicator on LZ-M (Mortise), LZ-L (Lever), and LZ-P (Panic) models is located on the exterior housing and is more accessible. If you are dealing with one of those models, contact dormakaba Multi-Housing Support before assuming drill-out is required.

What Happened — Understanding the Failure Mode

This lockout scenario occurs when a dormakaba EVO LZ lock fails to connect to Wi-Fi during commissioning, the deadbolt engages before setup completes, and the lock never becomes reachable in ButterflyMX. The room is now inaccessible and the lock is in an uninitialized state. The lock responds blue + red to the **1# key code which indicates it is offline.

The key indicator is the **5# star code result — this is the first thing to check and determines the entire recovery path.

Run **5# Before Anything Else

Press **5# on the lock keypad. This tests the internal Wi-Fi board communication and determines whether the lock has any possibility of connecting to a network.

**5# is Blue + Green: Attempt Network Connectivity First

If **5# returns Blue + Green, the Wi-Fi board is functional. The lock failed to commission because it couldn't reach the building's Wi-Fi — not because of a hardware fault. Do not drill out yet. There is a viable recovery path.

Option A — Connect via Mobile Hotspot

A mobile hotspot is the fastest way to get the lock online without depending on the building's Wi-Fi network:

1. Enable a mobile hotspot on a smartphone
   • iPhone: Settings → Personal Hotspot → enable "Maximize Compatibility" (forces 2.4 GHz — required)
   • Android: Enable hotspot → confirm it is set to 2.4 GHz if the option is available
2. Stand physically near the lock with both the hotspot phone and the commissioning phone
3. Open the Lyazon Utility App → Find Device → enter *#*# on the keypad
4. When the lock appears in the app → Edit Settings → enter the hotspot SSID and password
5. Wait for the lock to connect — confirm with **1#:
   • 🔵🟢 Blue + Green = lock connected ✅ → lock can now receive its initial programming
   • 🔵🔴 Blue + Red = still not connecting → try Option B

💡 Once the lock connects to the hotspot and downloads its initial programming, the Swipe to Open function may become available — allowing the door to be opened remotely without physical access to the interior. Alternatively, the Tap to Open or ButterflyMX PIN may be used as well.

Option B — Connect via a Nearby Property Network

If a hotspot is not available or Option A fails:

1. Confirm whether a nearby property Wi-Fi network is accessible at the lock location
2. The network must be 2.4 GHz 802.11b/g/n — confirm with the property's IT team or ISP
3. Open the Lyazon Utility App → Find Device → enter *#*# on the keypad
4. Edit Settings → enter the property network SSID and password
5. Confirm connection with **1# — Blue + Green = connected ✅

⚠️ If the building's main Wi-Fi network is what caused the original commissioning failure (wrong frequency, misconfiguration, weak signal), connecting to it again will produce the same result. Resolve the network issue first or use the hotspot option instead.

If Network Connectivity Is Restored — What to Do Next

Once the lock connects to a network and downloads its initial programming:

1. Confirm **1# returns Blue + Green
2. Confirm **2# returns Blue + Green (cloud connection)
3. Open the Lyazon Utility App — confirm the lock appears as Connected
4. Attempt Swipe to Open or Tap to Unlock from the ButterflyMX app to open the door
5. If Swipe to Open or Tap to Unlock is available → open the door → prop it open → complete commissioning normally
6. If the lock connected but Swipe to Open is not yet available → create an Access Code on Demand from ButterflyMX OS

**5# is Blue + Red

If **5# returns Blue + Red, the lock may have an internal Wi-Fi board cable fault. The cable on the right side of the interior assembly connects both power and the Wi-Fi board. If this connection is compromised or loose, the lock cannot reach Wi-Fi or download its initial programming regardless of network conditions.

Why Standard Recovery Paths Don't Work in This State

Common Causes of a Blue + Red **5# Result

• Cable not fully seated during installation
• Cable nicked or damaged during installation
• Molex connector twisted or compromised (these connectors are fragile — handle carefully during all installations)

Resolution Path

When **5# is Blue + Red and all recovery options above have been ruled out, drilling out the lock is the most likely required resolution. Please reach out to dormakaba support for further guidance:

Preventive Best Practices

These steps prevent this scenario from occurring:

• ✅ Inspect the Wi-Fi board cable before powering on — open the battery cover and confirm the cable is fully seated and undamaged before commissioning begins
• ✅ Test each lock fully before moving to the next — confirm **1# returns Blue + Green and the lock appears Connected in the Lyazon Utility App
• ✅ Confirm the lock is online in ButterflyMX before closing the door — do not allow the deadbolt to engage until commissioning is verified
• ✅ Keep doors propped open until commissioning is fully confirmed
• ✅ Test with a hotspot before the site visit if building Wi-Fi readiness is uncertain
