Wireless Garage Door Keypad Battery Replacement
Start by turning the key on the bottom of the spacer counterclockwise; then, remove the system from its space.
All batteries die eventually, and a garage door wireless keypad is no exception. Replacement of this battery can be done in a few easy steps and requires only some tools and a little force.
Basic steps
Start by turning the key on the bottom of the spacer counterclockwise; then, remove the system from its space.
Next, release the back plate and remove the old batteries from the keypad.
The wireless keypad batteries should be replaced with two new 3V CR2023 batteries. Test both the polarity and operability.
The batteries should be replaced with the same type of batteries, and the positive and the negative terminals should be checked during the replacement. While replacing the battery, no programming is lost since the keyless entry system has been designed to ensure that the pin and code do not reset.
The 740CB/66LM keypad model
The 740CB/66LM keypad is an older model and has a screw that holds the battery cover in position. In this case, a screwdriver is needed to remove the battery cover. Once the battery cover is removed, the battery should slide off.
The 940CB, 976LM, and 376LM keypad has a pinhole right at the bottom of the keypad cover. To replace the battery, insert a small screwdriver into the hole and gently pull it outward so that the cover loosens and slides downwards. Both thumbs should be used to apply pressure to the top end of the battery cover and then slide it down and away.
The 940D, 940EV, 977LM, 877LM, 377LM, and 877MAX are the most current models, with an oval cut-out on the top of the battery cover. To remove the battery cover, insert a flathead screwdriver into the oval cut and apply sufficient pressure on the screwdriver and against the battery cover. To remove the battery cover, slide the lid down gently.
Before replacing the battery, check whether the existing batteries have sufficient power to operate the keypad. To check this, press the light bell button for a few seconds. While the button is pressed, the red LED on the keypad should flash brightly. If the red LED only flashes dimly, the battery needs to be replaced. Additionally, if the keypad backlight brightness varies while pressing the light bell button and during the transmission of a radio code, then the battery should also be replaced.
