How to replace Schlage battery?

Schlage electronic locks are used for many commercial and residential purposes. They provide both physical security and an easy way to get in or out of a building, but this will depend on the type of door that is being locked. Schlage locks use batteries as their power source, which means they need to be replaced periodically. But how to change the battery on a Schlage keypad lock? Here’s the step by step guide in replacing the battery in your Schlage electronic lock:

Step 1: Use a Phillips-head screwdriver to remove the screw that holds the cover on the inside of your door’s handle. Once you’ve done that, grasp it by its sides and pull off this piece from where it was attached to.

Step 2: For models that use a 9-volt battery, pull out the battery gently from the compartment and carefully disconnect the wire cap from the top of the old battery.

Step 3: Get your new 9-volt battery and realign the wire cap, then insert the new battery in the battery compartment. Make sure that the wirings are back in place as well.

For other models that use AAA batteries, remove the old batteries and replace them with new AAA batteries, then proceed to the next step.

Step 4: Grab the cover and place it back by securing the screw preventing it from moving.

Remember to dispose of the old batteries properly. Keeping our environment and everyone around us safe is important.

Once you have installed the new batteries, your electronic lock should be back up and running. It doesn’t require reprogramming the system after changing the battery. The Schlage lock battery replacement is not a difficult task.

What are the signs that the battery in Schlage Electronic Lock is getting weak?

Schlage keypad lock is designed to automatically notify you when its battery is getting weak. After entering the valid keycode, the lock will produce a high and low beep. Right after this, monitor the next color flashing. If you see a red and green flashing, it is a warning telling you it’s time to replace the battery. If you see a blinking red even though you didn’t put in the valid keycode, then the system is telling you that your battery is in a critical state and needs to be replaced as soon as possible. The keypad will not open the lock when the battery is low, so it’s very important to monitor the color of your keypad so you can act right away.

Also, if you know that one of your batteries is getting weak, then it would be an excellent idea to replace all of them at once with brand new ones. This will prevent any future inconvenience caused by low battery power and also save money in the long run.
