Check The Batteries

Schlage locks have recommendations on which batteries will go with this brand’s electronic/smart lock products. If you violate these notes, your lock will be in trouble and not work as expected.

Good performance is the first factor you need to ensure for these power sources. Many users often mistake old batteries with new ones, leading to abnormal operations.

Schlage also recommends that all their products have only alkaline batteries as a sole power source. While some other rechargeable batteries (such as lithium) can also do this task, there is a great risk of the lock not working.

Check The Battery Connector

In case that Schage’s batteries are perfect, but the product still won’t work, it’s best to give your attention to the battery connector. Improper connection will prevent this item from working properly as a conductor.

The battery connector breaks (or opens) after you accidentally damage it in a few cases. If you’re in this situation, you’ll need to replace it with a brand new one.

Reset Factory Settings

Reset factory settings are complicated to complete with the five small steps below. Follow them, and you’ll have your Schlage lock fixed!

Locate the Factory Preset Code

The first step you need to take to reset this product is to verify the original code (default code) for this device. You can find it in the manual that comes with it or on the stickers outside the lock.

This code number plays a role in this entire reset process. Once you lose all information about this code, the manufacturer will not help you with anything.

Open the Lock Housing

Use a screwdriver to remove all fixing screws on the back of the padlock. After everything is perfect, look for the preset codes on the white sticker.

Push Reset Button or Disconnect Battery

After completing the above two steps, now it’s time to reset the Schlage lock using the two methods available below.

If you find the reset button under the lock cover, you need to press and hold it until the red light disappears. Release your hand, and wait until the light turns blue shortly after. That means that your key has finished resetting itself.

If there is a lack of a reset button, you will have to follow a slightly more manual method – disconnect the device’s battery.

Clear the Door Lock Codes

Now it’s time to delete the current passcode! It would help if you held the “Schlage” button on your keyboard until the light turned green.

Release the hand holding the button and spend the next 10 seconds reconnecting the battery of the dongle. After completing this task, you need to keep pressing and holding the “Schlage” button again until a “beep” sounds.

Reset the Lock

To complete the Schlage reset process, you will need to enter the factory preset code with the product. Wait until the setup is done, then end this step by entering your new codes.
