Step 1: Identify the Type of Remote
Craftsman offers several types of remote controls:
- Standard 1-button, 2-button, or 3-button remotes
- Mini remotes (keychain style)
- Wireless keypad mounted outside the garage
Each model may open slightly differently, but the basic process is similar.
Step 2: Gather Your Tools
Most Craftsman remotes can be opened without special tools, but having these nearby helps:
- A small flathead screwdriver or coin (like a quarter)
- A clean, dry cloth
- New battery (check your owner’s manual or the back of your remote for the battery type—commonly CR2032 or 9V)
Step 3: Locate the Seam or Battery Compartment
Turn your remote over and look for a seam or a small notch, usually located along the side or bottom. This is where you will insert the flathead screwdriver or coin to pry it open.
Step 4: Carefully Pry Open the Remote
Insert the flathead screwdriver or coin into the notch and gently twist to pop the remote open. Be careful not to use excessive force to avoid cracking the plastic.
Step 5: Remove the Old Battery
Take note of how the battery is installed—observe the orientation of the “+” and “−” sides. Use the screwdriver or your fingernail to gently remove the battery.
Step 6: Install the New Battery
Insert the new battery in the same orientation. Ensure it sits firmly in place.
Step 7: Reassemble the Remote
Snap the two halves of the remote back together until you hear a click. Test the remote to make sure it works correctly.
Replacing the Battery in a Wall-Mounted Control Panel
Some Craftsman garage door openers also include a wall-mounted control panel that may use a coin-cell or AA battery.
Steps:
- Remove the cover by pressing or sliding it.
- Remove the old battery.
- Replace with the correct battery type.
- Reattach the cover and test functionality.
