How to fix Schlage smart lock blinking red light?

To fix your Schlage smart lock blinking red light, you must replace its battery. If still not fixed, try resolving the errors in the programming or work on the user code.

Here are the steps to fix your Schlage lock:

1. Replace the batteries of your Schlage lock

The first and most crucial step for fixing the flashing or blinking red light on your Schlage smart lock is to replace its batteries. Low-powered batteries are the most common cause of such a problem.

Moreover, at times, there’s also a possibility that you may have entered the wrong batteries or the right ones in the wrong way. In any case, you need to check all these three factors before heading to the next hack.

Below are the steps to replace the batteries of your Schlage lock:

  1. Firstly, release the battery tray of your lock to remove all its screws.
  2. Next, you’ll see an AA battery and a 9-volt battery once you remove the screws. Take these batteries out.
  3. Now, remove the connector attached to it.
  4. Lastly, reassemble the new batteries and then place them within your system. This will solve the blinking light issue in no time.

2. Enter the correct user code

If the problem isn’t resolved even after changing your smart lock batteries, then you might be entering the wrong code.

This occurs when you see the red blinking light once you enter the user code, and it goes wrong. In such a case, re-enter the user code until you see the green light indicating that the problem has been resolved.

Moreover, you may even notice a red light while adding a new user. This may prevent you from doing so since you have maximized the number of user codes. In such a case, you need to delete any of your existing user codes and then try adding one.

You may be entering the user code wrong; thus, the first code will not match the one you typed the second time. So, try again and enter the code correctly.

In addition, there may be a coincidence that the user code you want to enter may have the same digits as your program code, or such a user code may exist too. Therefore, always enter a unique user code to avoid unnecessary problems and for your safety.

Furthermore, you may also notice such a blinking red light while deleting existing user code. This usually happens when your first code doesn’t match the second one. So, ensure to enter a similar code to avoid such an issue.

3. Try resolving the error in the programming

After working on your user code, the following hack is to check out any error in the programming and, if present, try resolving it.

Programming errors may occur when your programming error may be the same as your user code. In such a case, ensure to enter a special, unique code to avoid mishap.

Moreover, another reason may be that the programming code you’re entering may not match the second one. This will prevent you from programming the lock. So, to resolve this error, enter the first and the second code, ensuring they’re the same.

4. Try restoring the factory settings on your keyboard

The next hack is to clear up all the glitches and bugs by restoring your device to its factory settings. It’s pretty easy and won’t require much time and energy.

Below are the steps to factory reset your smart lock:

  1. Firstly, remove your keypad’s batteries.
  2. Next, press and hold down the Schlage button for around 15 seconds.
  3. While pressing and holding the Schlage button, put the batteries back again.
  4. You’ll soon hear a beeping sound and see the green light indicating that the problem has been resolved.
