Now that we have our checklist handy, let’s dive deeper into each of these troubleshooting steps.

Check if Lock Override is Disabled

If the Lock Override feature is enabled on your Schlage smart lock, this is what may be preventing the lock from working.

The Lock Override feature essentially makes your smart lock function like a standard lock. In other words, this feature enables you to unlock the device manually in situations that call for emergency access.

Disabling this feature may fix the problem and get the lock to work again. To do this, follow these steps:

  1. Take off the cover on the battery compartment in the internal assembly
  2. Remove the battery from the socket
  3. Look for the lock override slot
  4. If set to the lockout option, rotate the slot to normal with a screwdriver
  5. Insert the battery and place the cover back on

Following this process should disable the Lock Override feature and allow you to unlock your Schlage smart lock with your code as intended. If this was not the issue, however, you will need to continue with the troubleshooting.

Ensure You Are Entering the Correct Input Code

This may seem pretty obvious, but you will be surprised to know how commonly people misremember their smart lock input code or enter the wrong one in a rush.

If the light on the lock blinks red, it indicates that you are entering an incorrect code. Make sure that you have the right input code.

Type it in slowly, taking care to press down on each button. Once you enter the right code, the light on your Schlage lock will blink green, indicating that it is unlocked.

Disable Vacation Mode

The Schlage smart lock comes with the vacation mode feature, which enables you to disable the lock temporarily while you are on vacation. Since there is usually no need to open the lock when the occupants of the house are on vacation, this deactivates the lock opening mechanism and ensures that there are no surprise intruders in your house.

If vacation mode has been enabled by accident on your Schlage lock, it might give the impression of being non-functional. You need to check and deactivate this mode to get back to normal functionality.

To do this, you first need to use the keypad to put in your programming code. Then, watch out for a short beep and the light on the lock to flash green. If this happens, you can be sure that vacation mode has been disabled.

Please note that while this is the default method of disabling vacation mode, there might be slight variations based on the model of Schlage smart lock you have installed. To know the process for sure if the above method does not work, consult the owner’s manual of the lock and follow the instructions provided therein.

Check if the Batteries Need Replacement

All Schlage smart lock models draw power from some kind of battery. In some models, this is accomplished using multiple AAA batteries while other models might use CR123A batteries. No matter what kind of battery your model uses, there is every chance that the reason that your smart lock is not working is a drained battery.

Smart lock batteries often do not last as long as expected and might die suddenly. The unit will then lose power and fail to create a stable connection with the smart home hub. This ceases all normal functionality. To rule out this issue, you need to try using the lock after replacing the batteries.

Carefully read your manual to find out the exact kind of batteries your lock uses and the instructions to replace them in the lock housing. Follow the instructions closely, taking care to preserve battery polarity and following recommendations in terms of specific battery brands and models.

Once you have replaced the batteries, reset the smart lock and check if normal functionality has been restored. If it has, the issue is fixed. If not, you can go on and try the next fix.

Reset Connection with Smart Home Hub

A spotty connection with your smart home hub can sometimes be the culprit if your Schlage smart lock is not working. Range issues, interference from other networks or appliances, and physical barriers in the line of sight can cause this issue during regular use. Quickly resetting the connection of the lock unit with the smart home hub might do the trick.

To do this, you need to first disconnect your lock unit from the smart home hub. Instructions to remove an existing connection should be clearly mentioned in your product manual.

Once you check with the smart home hub app or interface that there is no connection with the lock, remove the batteries from the lock unit. After waiting for a couple of minutes, replace the batteries and close the battery housing.

Now, you can add your smart lock back to your smart home hub and check if the problem is resolved. In most cases, this should be enough to get your smart lock working again.

Check the line of sight from the lock to the smart home hub device or router and remove physical barriers or offending appliances like microwaves from the area to maintain a stronger, reliable connection.

Run a Factory Reset

A factory reset should be one of your last resorts in the event that none of the other methods yield any results. Running a factory reset restores the software of any electronic device to its default system state. All stored information on the device is erased in the process.

Restoring your Schlage lock to its default settings will, in most cases, enable it to resume optimal functionality. Moreover, please remember that this will completely erase the on-board memory of the device, removing any custom programming you might have, all of your custom user and programming codes, and all other settings.

Also, once you complete the reset, you need to have quick access to the documentation provided with the lock to reference the default user code and programming code.

First, remove the batteries from the lock unit. Then, you need to press and hold down the Schlage button on the keypad for at least ten seconds. Then, replace the batteries in the unit and press and hold the Schlage button for ten more seconds. Once the reset is complete, you should hear a confirmation beep and see a green light.

Now, you can try entering the lock PIN (“default user code”) and the lock should be functional.

To check if the lock has resumed working, type in one of the default preset user codes.

Contact Schlage Customer Support

In case none of the above methods worked and your Schlage lock is still non-functional, or you simply need a professional to guide you through the troubleshooting process step-by-step, you can always contact Schlage support.

A Schlage technician, equipped with complete knowledge of the ins and outs of the lock, will slowly and effectively run you through the process to help you get to the root of the problem.

Additionally, the technician will also be able to tell you exactly how to fix the issue and whether or not your lock requires replacement.

Replace Your Schlage Smart Lock

If all else fails, your Schlage lock has likely run its course or was faulty to begin with. In cases of this type, your best bet is to replace the lock altogether and install a brand new one yourself or with the help of a professional.

Alternative: Use Physical Key as a Backup

This isn’t a “fix,” but in a pinch you will appreciate that Schlage also has a physical key backup. Not all smart lock manufacturers are nice enough to include this feature!

If nothing else, you can open the lock with a key and this should allow you to check whether or not the deadbolt mechanism is causing the problems.

Consider the Effects of Cold Weather

If your lock stopped working alongside a cold front, there is one final piece to consider.

Although the Schlage locks are rated for outdoor use, ice and snow can cause issues with batteries, keypads, and electric components — all of which are required in order for a smart lock to work.

Since this video explains it better than we could, give it a watch if your smart lock woes seemed to coincide with the changing of the seasons:

Final Thoughts
