The Schlage smart electronic lock is the ultimate security measure for the safety of your home, running on batteries. When there are signs of low battery, you may replace them with new ones, but sometimes problems arise immediately after this task. The Schlage lock not working after a battery change can be frustrating, but fear not, the solution is easier than you think. In just a few steps, you can check and reset your device, getting it back to normal operation.

If you’re facing this issue and looking for answers, you’re in the right place. This article will guide you through the process of troubleshooting and resolving the Schlage lock not working after a battery change problem.

Schlage Lock Not Working After Battery Change – Why?

There are several potential causes for a Schlage lock not working after replacing the battery. The first thing to suspect is the new battery you’ve installed. Numerous battery-related issues can significantly affect the normal operation of the lock.

Wiring can also sometimes be the culprit behind operational issues with the device. Wiring acts as a conductor that provides power for the lock’s operation. If this conductor fails, the lack of power can cause the lock to stop working immediately.

Additionally, a code error can sometimes be the reason for the Schlage lock’s non-functioning after a battery change. This error can appear and adversely affect the operation of the lock.

How To Solve Schlage Lock Not Working After Battery Change

Check The Batteries

The first step is to ensure you’re using the correct batteries for your Schlage lock. Schlage recommends specific battery types for their electronic/smart lock products. Using the wrong batteries can lead to abnormal operation. Alkaline batteries are the preferred choice, and while some other rechargeable batteries like lithium may work, there’s a greater risk of the lock not working correctly.

Each Schlage model specifies the appropriate number and type of batteries required for stable operation. Refer to the following table for guidance:

  • Sense Smart Deadbolt/ Connect Smart Deadbolt/ Encode Smart Wi-Fi Deadbolt: AA – 4 batteries
  • Touch locks/ All models of Keypad locks: 9-volt – 1 battery
  • Locks with Built-In Alarm: AAA – 2 batteries

Check The Battery Connector

If your Schlage batteries are correct, but the lock still won’t work, inspect the battery connector. An improper connection can prevent the lock from functioning properly as a conductor. In some cases, the battery connector may be broken or damaged, requiring replacement with a new one.

Reset Factory Settings

Resetting factory settings can resolve the issue with the following five steps:

  1. Locate the Factory Preset Code: Find the original code (default code) for your device in the manual or on stickers outside the lock. This code is crucial for the reset process.
  2. Open the Lock Housing: Remove the fixing screws on the back of the padlock with a screwdriver. Look for the preset codes on the white sticker.
  3. Push Reset Button or Disconnect Battery: If your lock has a reset button under the cover, press and hold it until the red light disappears and turns blue. For locks without a reset button, disconnect the battery manually.
  4. Clear the Door Lock Codes: Hold the “Schlage” button on your keyboard until the light turns green. Reconnect the battery and continue holding the button until you hear a “beep.”
  5. Reset the Lock: Enter the factory preset code and wait for the setup to finish. Conclude by entering your new codes.
