This article will demonstrate how to change battery in liftmaster garage door opener. It will walk you through the process of changing the battery step by step.

It’s annoying to learn that your garage door isn’t functioning correctly. However, in other situations, the answer may be as easy as replacing the garage door opener’s battery.

To pop up the remote casing and access your battery, you’ll need a flat head screwdriver or a small knife. Check your wall control unit first, since the lock/vacation button may have been mistakenly hit, before raiding your toolbox for batteries and screwdrivers.

Consider the following points:

• The polarities of the batteries are marked in the battery slots. Based on these signals, double-check and replace the batteries.
• If you’re not sure what kind of batteries you’ll need, take out the old ones, inspect them, and then buy new ones.
• Check the Internet for recycling centers in your area if you don’t know where or how to dispose of old batteries.

The keypad comes with batteries, which should last for around a year. You’ll need to replace them just after they’ve worn out.

How to change battery in liftmaster garage door opener

In just four easy steps, you can replace the battery in your LiftMaster keyboard:

1. To reveal the number pad, slide the keypad cover open. This is where you’ll find a battery compartment that you can access. Don’t get too worked up if you can’t find it. Simply read the manual and follow the instructions.
2. Remove the slotted batteries from the battery compartment. These are old batteries that must be discarded. Keep in mind to dispose of them properly and safely.
3. Replace the battery with the new one.
4. Remove the battery cover and replace it.

Your Garage Door Isn’t Opening for Other Reasons

It’s a good idea to examine the remainder of your garage door if the garage door still won’t open after you’ve gone through the entire keypad checklist. The door may not open for a variety of reasons.

1. Unplugged garage door opener: It may appear simple, but the door may have been unplugged, preventing the opener from working. Make a quick check to see if this is the case.

2. Is the door unable to fully open due to a blocked sensor? The sensor may be obstructed, signaling that something is blocking the door. Clean the garage door sensor’s photo-eye and try opening the door. If it still won’t open, the sensor may need to be replaced. Here’s how to figure out whether your garage door sensor is broken.

3. Broken springs: The springs on your garage door are what allow it to open and close with enough tension. Check your springs if the door won’t open. Is there anything wrong with them? Are they damaged or worn out? Then this is your justification. A word of caution: while you can change your own springs, it’s strongly advised that you get a professional to do so because they’re extremely risky.

When your garage door keypad stops working, it’s considerably easier to fix than you would believe. If you follow the advice in this post, you’ll have the door open in no time.
