Yale Assure Lock 2 Troubleshooting: Keypad, Connectivity & Battery

The Yale Assure Lock 2 is a versatile smart lock available with multiple connectivity options (WiFi, Bluetooth, Z-Wave, Zigbee, or Matter). This guide covers common issues across all variants.

Lock Not Responding

Check the Basics

• Battery level: Check in the Yale Access app—replace if low (use 4 AA batteries)
• Door alignment: Make sure the deadbolt extends and retracts smoothly by hand
• Connection type: Know whether your lock uses WiFi, Bluetooth, Z-Wave, or Zigbee

Lock Won't Lock or Unlock

1. Try using the keypad—if it works, the issue is connectivity, not the lock itself
2. Check the app for connection status
3. Remove and reinsert batteries to power cycle
4. Make sure you're within Bluetooth range if not using WiFi
5. For Z-Wave/Zigbee: check that your hub is online

Deadbolt Jams or Binds

• Check door and frame alignment—door may have shifted
• Adjust the strike plate position if the deadbolt doesn't align
• Lubricate the bolt with graphite (never use oil-based lubricants)
• Check that the mounting screws aren't over-tightened, which can warp the lock body
• Weather changes can cause wooden doors to swell—this is common

Motor Makes Grinding Noise

• Usually indicates misalignment—check door, frame, and strike plate
• Deadbolt may be hitting the strike plate at an angle
• If noise persists after realignment, contact Yale support (may be motor issue)

Keypad Issues

Keypad Not Responding to Touch

1. Wake the keypad by touching it—numbers should illuminate
2. Clean the keypad with a dry microfiber cloth
3. Check battery level—low batteries can cause keypad issues
4. Extreme cold can affect touchscreen responsiveness
5. Try removing batteries for 30 seconds and reinstalling

Code Not Working

• Verify you're entering the correct code (codes are typically 4-8 digits)
• Check if the code has an access schedule that's currently inactive
• User may have been removed from the lock—check in the app
• Try the master code to verify the keypad works
• After 5 failed attempts, lock may temporarily disable entry

Adding or Removing Codes

1. Use the Yale Access app or your smart home hub
2. Each code can have specific access schedules (always, weekdays only, etc.)
3. Guest codes can be set to expire automatically
4. If app isn't working, you can add codes directly via the keypad using the master code

WiFi Module Issues

WiFi Lock Won't Connect

1. Yale WiFi module only supports 2.4GHz networks
2. During setup, bring your phone close to the lock
3. Check WiFi password is correct (no special characters if possible)
4. Ensure your router isn't blocking new devices
5. Try setup in the Yale Access app (not the Yale Home app)

Lock Frequently Goes Offline

• Check WiFi signal strength at the door—may need an extender
• Router may be assigning changing IP addresses—use a reserved IP
• Restart your router
• Check for app and firmware updates
• Thick doors or metal frames can weaken signal

Bluetooth Issues

Can't Connect via Bluetooth

1. Enable Bluetooth on your phone
2. Stand within 10-15 feet of the lock
3. Force close the app and reopen
4. Toggle Bluetooth off and on
5. Unpair and re-pair the lock in the app

Bluetooth Range Too Short

• Normal range is 10-40 feet depending on obstacles
• Thick doors, brick, and metal reduce range significantly
• Other Bluetooth devices can cause interference
• Consider upgrading to WiFi module for remote access

Z-Wave and Zigbee Issues

Lock Not Connecting to Hub

1. Put your hub in pairing/inclusion mode first
2. On the lock, enter the master code followed by 7 + # (for pairing)
3. Bring a Z-Wave hub close during initial pairing if possible
4. For Zigbee, the lock should be within range of another Zigbee device to mesh
5. Exclude/remove the lock from hub and re-add if having issues

Lock Shows Offline in Hub

• Z-Wave: Check mesh network health—add repeaters if needed
• Zigbee: Ensure there are routing devices (not battery devices) between lock and hub
• Power cycle the lock
• Run a network repair/heal from your hub
• Check hub logs for error messages

Commands Delayed or Inconsistent

• Poor mesh network coverage—add smart plugs or switches as repeaters
• Hub may be overloaded—check for chatty devices on the network
• Distance from hub too great—strengthen mesh between them

Auto-Lock and DoorSense

Auto-Lock Not Working

1. Verify Auto-Lock is enabled in the app
2. Check the Auto-Lock timer setting (usually 30 seconds to 5 minutes)
3. If you have DoorSense, the door must be detected as closed
4. Without DoorSense, Auto-Lock uses a timer only

DoorSense Not Detecting Door

• Check magnet placement on the door frame—should be within 1" of the sensor
• Recalibrate DoorSense in app settings
• Metal doors/frames can interfere—try repositioning the magnet
• Use the included spacers if needed for thicker frames

Auto-Lock Triggers When Door Is Open

• DoorSense magnet is too close—move it slightly further from the lock
• Recalibrate after repositioning
• Without DoorSense, the lock can't tell if the door is open

Battery Issues

Batteries Draining Fast

• Normal battery life is 6-12 months depending on usage
• Frequent locking/unlocking drains faster
• Door misalignment makes the motor work harder
• Poor wireless signal causes increased power use
• Use high-quality alkaline or lithium batteries

Low Battery Warning

1. Replace batteries as soon as you receive the warning
2. The lock will continue working but may become unreliable
3. Use 4 fresh batteries of the same brand and type
4. Don't mix old and new batteries

Lock Dead—Won't Respond at All

1. Connect a 9V battery to the contacts below the keypad—this provides emergency power
2. Enter your code while holding the 9V battery in place
3. Once inside, replace the AA batteries immediately

App Issues

Can't Log Into Yale Access App

1. Try "Forgot Password" to reset
2. Check for app updates
3. Uninstall and reinstall the app
4. Make sure you're using the correct Yale app (Yale Access, not Yale Home)

Activity Log Not Updating

• Requires WiFi connection for remote logging
• Bluetooth logs sync when you're near the lock
• Pull down to refresh in the app
• Check that the lock shows as online

Factory Reset

To factory reset the Yale Assure Lock 2:

1. Remove the battery cover inside the door
2. Remove one battery
3. Press and hold the lock button while reinserting the battery
4. Continue holding until you hear two beeps
5. The lock is now reset to factory settings
6. All codes are cleared and you'll need to set it up again
