The Nest Thermostat works with most 24V heating and cooling systems, including furnaces, air conditioners, boilers, and heat pumps with either forced air or radiant delivery.

It works with conventional systems that have one stage of heating and cooling and a second stage of either heating or cooling.

It works with heat pumps that have one stage of heating and cooling and either aux or emergency heat.

And it works with HVAC fans.

The Nest Thermostat is designed to work if your home doesn’t have a common (“C”) wire. In some cases, particularly if you have a heating- or cooling-only system or use a zone controller, a C wire or other power-supply accessory may be necessary. See g.co/nest/cwire for details.

On my Smartcode Deadbolt, the lock beeps, the keypad flashes red, and the door cannot lock.
8 possible issues:



  1. The door handing process was not executed during installation. This step will teach your lock the orientation of your door and is crucial to lock operation.

    • Remove interior cover and battery pack.

    • Press and HOLD the Lock button while installing battery pack. Hold button until the latch bolt starts moving on its own.

    • Did the latch bolt retract and extend on its own when the battery pack was installed? Note: Latch bolt will only retract half way.
      NO - Remove battery pack, wait 15 seconds, then attempt the process again.
      YES - Door handing process was successful!



  2. The hole in the door is misaligned.
    Disassemble the lock, and reinstall it without the adapter ring on the exterior side of the door.

  3. The wrong deadbolt latch is installed.
    SmartCode deadbolts require a tapered latch bolt for ease of operation. If the latch being used is from an older lock, it will likely not have a tapered latch bolt. Remove the lock from the door, including the old latch. Replace with the new tapered latch that came with the lock and reinstall the lock.

  4. The deadbolt latch and strike are misaligned, causing the latch to bind.
    Adjust the tab of the lower strike (for your knob or lever) to help align the upper latch and strike so that the latch bolt enters the strike when the door is locked.

  5. The lower latch and lower strike (for your knob or lever) are misaligned, putting too much load on the deadbolt latch.
    As a test, rotate the turnpiece on the deadbolt so the latch is retracted (unlocked), and close the door. If you have to push, pull or lift the door to get it to close, adjust the position of the lower strike.

  6. The hole in the door frame for the latch bolt is not drilled deep enough.
    Make sure the hole in the door frame is drilled at least 1” (25 mm) deep.

  7. The mounting plate is placing tension on the torque blade.
    Attempt to lock and unlock the door with the key. If it is unable to rotate, remove the interior assembly from the mounting plate. Test the key again. If it is still unable to rotate, loosen the screws on the mounting plate and reposition the plate so there is no tension on the cylinder torque blade. Make sure the latch bolt can operate smoothly with the key and reinstall the interior assembly.

  8. The clutch is disengaged.
    Remove the battery pack. Remove the interior assembly from the door. Verify that the lock can be operated smoothly with the key while the interior is removed. Attempt to rotate the turnpiece on the interior assembly to the vertical position. If it cannot rotate to the vertical position, the clutch has become disengaged.
    Place the battery cover onto the interior assembly, making sure to align the turnpiece with the shaft. Rotate the turnpiece 180° clockwise (you will need to use force when rotating the turnpiece, and you will hear it click). This will re-engage the clutch.
    Align the turnpiece with the torque blade and reinstall the interior assembly on the door.

On my Smartcode Deadbolt, the Lock button does not lock the door.

On my Smartcode keypad, I can see the lock in my controller, but I can’t control it from the controller.
Four possible issues:
1. The system needs a repeater or router to reach the lock.
Adding repeaters to your system may help communication between your lock and the controller, especially if they are far away from each other.
2. The network confi guration changed.
If any repeaters or routers in the system were moved since adding the lock to the system, perform the “rediscover” process in your system’s user interface.
3. The lock is in sleep mode.
If the lock has been unable to communicate with the system after multiple attempts, it will go into sleep mode. Lock and unlock the door with a key so that the lock status transmits to the system. If it still does not communicate, remove (exclude/unpair) the lock from your system.
Then, pair (add/include) the lock with your system again. If the problem persists, add a repeater or router between the controller and lock if none presently exist in the system.
4. The light module or switch is not beaming capable.
Z-Wave locks: Ensure the light module or switch located between the controller and lock is beaming capable.
ZigBee locks: Ensure the router is reachable by both controller and lock.
On my Smartcode keypad, the lock fails to pair with a smart home system.
Two possible issues:

  1. The lock was not removed completely from another network before being paired with the new network.
    Follow your smart home system’s instructions to remove (exclude/unpair) the device from any other network. Then, attempt to pair (add/include) the lock again.

  2. The lock is not close enough to the controller.
    Some Z-wave systems require that the lock be within 12" of the controller during the pairing process. If the lock has already been installed on the door, remove the interior assembly from the mounting plate. Make sure the batteries are installed, and bring the interior assembly next to the controller. Follow your smart home system’s instructions to begin pairing at the controller. The lock may need to remain stationary for 60 seconds during pairing.
    Note: Some locks have an anti-tamper alarm that will sound if the interior is disconnect from the exterior. If this alarm is heard, perform the following.

    • Remove the battery pack from the interior.

    • Remove the exterior assembly from the door.

    • Connect the cable from the exterior assembly to the interior assembly.

    • Reinstall the battery pack.

    • Perform the pairing process while the interior and exterior are connected

On my Smartcode Touchscreen, Only two digits illuminate on the touchscreen.
SecureScreen is enabled. SecureScreen is an added-security feature that displays random digits before you enter a user code to unlock the door. This feature ensures that there are fi ngerprints on all digits so that codes cannot be identifi ed by examining the touchscreen for fi ngerprints. If desired, this feature can be disabled by turning switch #4 to the off position.
On my Smartcode Touchscreen, the batteries drain within one week.
The Wireless Card LEDs are staying on. Remove the battery pack, press and hold the program button for 10 seconds. Replace the battery pack. If the Wireless Card LEDs continue to stay on, contact Technical Support.
On my Smartcode Touchscreen, the door handing process does not happen automatically when the batteries are installed.
Two reasons:

  1. The handing process may have been executed previously
    Perform the manual door handing process
    If needed, the door handing process can be initiated manually. This is useful if the lock is being moved to a different door

    • Remove battery pack.

    • Press and HOLD the Program button while reinserting the battery pack. Release button once battery pack is installed. The status LED will flash red and green.

    • Press the Program button once more.

    • The latch bolt will extend and retract to learn the orientation of the door. Success: flashing checkmark symbol and single column of digits. Failure: flashing “X” pattern



  2. The battery level is too low.
    This is indicated by the Checkmark and Lock symbols flashing simultaneously five times with five beeps. Use a fresh set of batteries, and perform the door handing process again.

On my Smartcode Touchscreen, The lock beeps, the Checkmark and Lock symbols alternate flashing, and the door cannot lock
7 possible reasons:

  1. The door handing process was not executed during installation. Perform the manual door handing process in the Installation Guide.
    Perform the manual door handing process
    If needed, the door handing process can be initiated manually. This is useful if the lock is being moved to a different door

    • Remove battery pack.

    • Press and HOLD the Program button while reinserting the battery pack. Release button once battery pack is installed. The status LED will flash red and green.

    • Press the Program button once more.

    • The latch bolt will extend and retract to learn the orientation of the door. Success: flashing checkmark symbol and single column of digits. Failure: flashing “X” pattern



  2. The wrong deadbolt latch is installed.
    SmartCode deadbolts require a tapered latch bolt for ease of operation. If the latch being used is from an older lock, it will likely not have a tapered latch bolt. Remove the lock from the door, including the old latch. Replace with the new tapered latch that came with the lock and reinstall the lock.

  3. The deadbolt latch and strike are misaligned, causing the latch to bind.
    Adjust the tab of the lower strike (for your knob or lever) to help align the upper latch and strike so that the latch bolt enters the strike when the door is locked.

  4. The lower latch and lower strike (for your knob or lever) are misaligned, putting too much load on the deadbolt latch.
    As a test, rotate the turnpiece on the deadbolt so the latch is retracted (unlocked), and close the door. If you have to push, pull or lift the door to get it to close, adjust the position of the lower strike.

  5. The hole in the door frame for the latch bolt is not drilled deep enough. Make sure the hole in the door frame is drilled at least 1” (25 mm) deep.

  6. The mounting plate is placing tension on the torque blade. Attempt to lock and unlock the door with the key. If it is unable to rotate, remove the interior assembly from the mounting plate. Test the key again. If it is still unable to rotate, loosen the screws on the mounting plate and reposition the plate so there is no tension on the cylinder torque blade. Make sure the latch bolt can operate smoothly with the key and reinstall the interior assembly.

  7. The clutch is disengaged. Remove the battery pack. Remove the interior assembly from the door. Verify that the lock can be operated smoothly with the key while the interior is removed. Attempt to rotate the turnpiece on the interior assembly to the vertical position. If it cannot rotate to the vertical position, the clutch has become disengaged.
    Place the battery cover onto the interior assembly, making sure to align the turnpiece with the shaft. Rotate the turnpiece 180° clockwise (you will need to use force when rotating the turnpiece, and you will hear it click). This will re-engage the clutch.
    Align the turnpiece with the torque blade and reinstall the interior assembly on the door.

On my Smartcode Touchscreen, the Lock symbol does not lock the door.
No user codes are programmed.
If there are no codes in the lock, the lock symbol will not lock the door. This is indicated by the “X” pattern flashing three times with three beeps. Program at least one user code and test the Lock symbol again.
The door handing process was not executed.
Perform the manual door handing process, following the instructions inside the Installation and User guide.
The battery is too low to lock the door.
This is indicated by the Checkmark and Lock symbols flashing simultaneously five times with five beeps. Remove the batteries and replace with a fresh set.
The mounting plate is placing tension on the torque blade. The clutch is disengaged.

On my Smartcode Touchscreen, the touchscreen is unresponsive
Three possible issues:
Screen activation
To activate the screen, use one of the three options below:
1. Touch screen with palm or back of hand until digits illuminate.
2. Touch lower left area of screen (where Checkmark is located) until digits illuminate.
3. Touch screen with three or more fingers until digits illuminate.

One-second pause
The lock requires a one-second pause immediately after locking or unlocking before the touchscreen will re-activate. Fully remove hand from screen until the Checkmark or Lock symbol turns off, and then activate the screen again.

Touchscreen lockout
If three incorrect codes were entered within one minute, the touchscreen will lock for 60 seconds.
On my Smartcode, I can see the lock in my controller, but I can’t control it from the controller.
Four possible issues:
1. The system needs a repeater or router to reach the lock.
Adding repeaters to your system may help communication between your lock and the controller, especially if they are far away from each other.
2. The network configuration changed.
If any repeaters or routers in the system were moved since adding the lock to the system, perform the “rediscover” process in your system’s user interface.
3. The lock is in sleep mode.
If the lock has been unable to communicate with the system after multiple attempts, it will go into sleep mode. Lock and unlock the door with a key so that the lock status transmits to the system. If it still does not communicate, remove (exclude/unpair) the lock from your system. Then, pair (add/include) the lock with your system again. If the problem persists, add a repeater or router between the controller and lock if none presently exist in the system.
4. The light module or switch is not beaming capable.
Z-Wave locks: Ensure the light module or switch located between the controller and lock is beaming capable.
ZigBee locks: Ensure the router is reachable by both controller and lock.
On my Smartcode, the batteries drain within a few weeks.
Three possible issues:
1. The smart home system’s user interface falsely reports a low battery.
If you receive an alert from your smart home system indicating that the battery is low, confirm this is true at the lock. Turn on switch #1 so that the status LED flashes every six seconds. If the LEDs turn amber or green, followed by a red flash, the battery is low. If the red flash is not seen, the battery is not low. This is an error on the smart home system side that will often be fixed when the lock is manually locked or unlocked.
2. The smart home system controller’s communication with the lock is draining the battery.
Remove the lock from your system. Put a new set of batteries in the lock. Operate the lock in stand-alone mode for a week. If the batteries drain within the week, the problem resides in the lock. If the batteries do not drain, the problem may be the smart home controller. Call Technical Support.
3. The smart home system controller’s ping frequency is too high.
Decrease the ping frequency from the controller to the lock to the lowest possible setting.
On my Smartcode, the lock fails to pair with a smart home system.
Two possible issues:

  1. The lock was not removed completely from another network before being paired with the new network.
    Follow your smart home system’s instructions to remove (exclude/unpair) the device from any other network. Then, attempt to pair (add/include) the lock again.

  2. The lock is not close enough to the controller.
    Some Z-wave systems require that the lock be within 12” of the controller during the pairing process. If the lock has already been installed on the door, remove the interior assembly from the mounting plate. Make sure the batteries are installed, and bring the interior assembly next to the controller. Follow your smart home system’s instructions to begin pairing at the controller. The lock may need to remain stationary for 60 seconds during pairing.
    Note: Some locks have an anti-tamper alarm that will sound if the interior is disconnect from the exterior. If this alarm is heard, perform the following:

    • Remove the battery pack from the interior.

    • Remove the exterior assembly from the door.

    • Connect the cable from the exterior assembly to the interior assembly.

    • Reinstall the battery pack.

    • Perform the pairing process while the interior and exterior are connected.
