When your Chamberlain garage door remote starts acting up—slow to respond, weak signal, or not working at all—it’s usually a sign that the battery is running low. Luckily, replacing the battery is a quick and simple fix that requires no special skills or tools beyond a screwdriver or visor clip. Whether you’re using a standard 3-button remote or a compact keychain model, this article will walk you through how to safely remove and replace the battery in your Chamberlain remote, including warnings and proper disposal instructions.
Important Safety Warnings Before You Begin
Before starting the replacement process, please review these safety precautions carefully:
- NEVER allow children to handle or play with batteries. Coin-cell batteries are small and can be easily swallowed, which can cause serious injury or death.
- If a battery is swallowed, seek medical attention immediately.
- Use ONLY 3V CR2032 coin-cell batteries for all the listed Chamberlain remotes.
- Do NOT recharge, disassemble, incinerate, or expose the battery to heat above 212°F (100°C).
- Always dispose of old batteries properly to prevent chemical burns or environmental hazards.
Following these guidelines is crucial not only for your safety but also for the longevity and reliability of your Chamberlain remote control.
Tools You’ll Need
To remove and replace the battery, gather the following:
- A visor clip (usually comes with the remote) or a small flathead screwdriver
- A new 3V CR2032 coin battery
- A clean cloth or tissue to clean contacts if necessary
- A small Phillips screwdriver (for the MC100-P2 model)

The 956 series keychain remotes are ultra-compact and designed for portability. The process is slightly different from the larger remotes.
Steps:

- Take out the old battery, being careful not to damage any small components inside.

The MC100C-P2 is a universal mini remote that works with most major garage door brands. It differs slightly in construction, requiring a small screwdriver to open.
Steps:
- Remove the two screws on the back of the remote using a small Phillips screwdriver.

Even though it’s “universal,” this model still uses the standard CR2032 battery like most Chamberlain remotes.
After Replacing the Battery
Once the battery is replaced, here are a few quick tips to finish the job:
- Check the polarity: Always make sure the positive side of the battery is facing up.
- Check the fit: Ensure the battery is snug and that the cover is secured completely.
- Test the remote: Try it at various distances to ensure the signal is strong.
- Reprogram if needed: In rare cases, replacing the battery may cause the remote to lose its programming. If that happens, press the “Learn” button on your opener unit and follow the instructions to resync your remote.
Battery Disposal and Safety Tips
Batteries should never be thrown in the trash. They contain chemicals that are harmful to the environment and must be disposed of responsibly.
Here’s how:
- Take them to a local recycling center or hazardous waste facility.
- Drop them off at participating stores, like Home Depot, Lowe’s, or Best Buy, which often have battery recycling bins.
- Check with your city or county for scheduled hazardous waste collection days.
Also, store new batteries out of reach of children and pets, and keep old ones in a safe container until you can dispose of them properly.

Whether you’re using a classic 950EV or a modern 953EVC or 956EV keychain remote, the process is simple as long as you use the correct tools and battery type. Always choose a 3V CR2032 coin-cell battery, follow safety instructions closely, and dispose of the old battery responsibly. With just a few minutes of effort, your remote will be working like new—ready to open your garage door with a single press.
