Will This Battery Work in Your Keypad?
Chamberlain and LiftMaster list a 9V alkaline battery for models such as the 940EV, 877MAX and 878MAX, and Genie lists a 9V battery for its GWK keypads. Other keypads use different power sources, which makes a quick check worthwhile.
Not every keypad takes a 9V battery. Chamberlain notes that some older models use a 12-volt battery, the Genie GK-R and GK2-R use two AAA batteries, and the myQ Video Keypad uses a rechargeable battery. The 9V match is by battery type and is not an endorsement from any keypad brand. Confirm the fit in your battery compartment before use.

Keypad Battery Replacement Difficulty
This is an easy job on an intact, reachable keypad. You open a small cover, swap one battery and test the keypad. The tricky parts are matching the right battery to your model and releasing the cover, which differs from model to model. Tap a slice to highlight it.
- 30% Opening the cover
- 15% Swapping the battery
- 30% Choosing a compatible battery
- 25% Testing the PIN & any reprogramming
A tight older cover, a leaked battery, a damaged connector or broken cover tabs turn this into more than a simple swap. Chamberlain also says you may need to reprogram your keyless entry after a battery change.
Difficulty score and effort split are an editorial estimate based on the manufacturer’s documented replacement procedures, not an official rating.
How to Replace Your Keypad Battery
Tap each step to tick it off as you go.
- 1Check your keypad modelFind the model number on the back or inside the battery compartment, then confirm it needs a 9V alkaline battery.
- 2Open the cover940D, 940EV, 977LM, 377LM, 877LM, 877MAX and 878MAX: push a flat-head screwdriver into the oval cut-out at the top of the cover and slide it down past the locking tabs. 740CB and 66LM: remove the bottom Phillips screw, then slide the cover down. 940CB, 976LM and 376LM: push a small Phillips screwdriver into the bottom pin hole, pull gently outward and slide the cover down. Newer models such as the CH148 and CH348: slide the cover down.
- 3Swap the batteryLift out the old 9V battery and disconnect it from the power leads. Connect the new 9V alkaline battery in the same orientation.
- 4Close the coverPlace the battery and leads in the housing without trapping them. Slide the cover back until it locks, or until it clicks on newer models, and refit the screw if your model has one.
- 5Test the keypadPress a key to check the lights, then enter your existing PIN to confirm the opener responds.
Check the battery connection and orientation, and make sure the cover is not trapping the leads. If the keypad lights up but the opener does not respond, follow the reprogramming steps in your keypad manual. Try the keypad away from its mounting surface too, because Chamberlain lists surface interference as one possible cause.

Safety, Storage & Disposal
The two terminals on a 9V battery sit close together. If a metal object such as a key, coin or paper clip touches both, the battery can heat up and start a fire. This applies to used batteries as well as new ones.
- Keep spare batteries in their original packaging until you need them.
- Never recharge this single-use alkaline battery.
- Store at normal room temperature. Refrigerating batteries is not recommended.
- Avoid bare-skin contact with any leaked fluid.
- Tape over the terminals of used batteries, then take them to a household hazardous-waste or battery collection point.
9V Garage Door Keypad Battery: FAQ
Do all garage door keypads use a 9V battery?
No. Several Chamberlain and LiftMaster keypads and the Genie GWK keypads use a 9V battery. Some older models use a 12-volt battery, the Genie GK-R and GK2-R use two AAA batteries, and the myQ Video Keypad uses a rechargeable battery.
How long does a 9V battery last in a garage door keypad?
There is no verified runtime for this exact battery in a named keypad. Service life depends on how often you use the keypad and on conditions such as cold weather. The five-year figure is an advertised shelf life, which covers storage and not operation.
Is this 9V battery rechargeable?
No. It is a single-use alkaline battery and must not be recharged.
Can I use a lithium or rechargeable 9V instead?
Only if your keypad manual allows it. Chamberlain’s replacement guide specifies or recommends alkaline batteries for the models listed above.
Will I need to reprogram my keypad after changing the battery?
Test your existing PIN first. Chamberlain says you may need to reprogram your keyless entry after a battery change. For that reason, follow the programming steps for your exact model if the keypad does not communicate with the opener.
Does a five-year shelf life mean five years in my keypad?
No. Shelf life describes how long the battery can sit in storage before use. Once it is installed, the lifespan depends on the device and how you use it.
Can this battery leak?
Yes, it can. The listing advertises a five-year leak-free shelf life, but heat, damage, charging attempts and deep discharge all raise the risk of leakage in any alkaline battery.
How should I store and dispose of 9V batteries?
Keep them in their original packaging and away from metal objects. Cover the terminals with tape before disposal, then use a household hazardous-waste or battery collection point.
