Garage openers & gate remotes battery

Find the right battery for your remote or keypad

Use our Garage/Openers & Gate Remotes Finder to look up garage door opener batteries and gate remote batteries in seconds.

How to use it

1. Pick your Brand (Chamberlain/LiftMaster, Genie, Hörmann, Nice, CAME, Marantec, Linear, BFT, FAAC, etc.).
2. Start typing the Remote model (e.g., 893MAX, G3T-R, HSE 4 BS, FLO2R).
3. The table shows the frequency, the correct battery (CR2032, CR2016, CR2450, 23A 12V, etc.), and a quick programming note.
4. Click the battery code to open a purchase search.
5. Need a keypad? Search the model—many keypads use a 9-volt battery.

Which battery do I need?

Most remote garage door opener batteries are coin cells:

• CR2032 — the most common for Chamberlain/LiftMaster (e.g., 893MAX, 953EV), Genie G3T-R, Nice ERA-INTI, BFT MITTO, FAAC XT2/XT4, Marantec Digital 382/384, and many others.
• CR2016 / CR2450 — found in select remotes and key fobs.
• A23 (23A, 12V) — used on some older Nice FLO and legacy gate remotes.
• AAA (1×) — certain Hörmann HS 4 BS.
• 9-volt battery for garage door keypad — common on universal and brand-name keypads (Chamberlain/LiftMaster, Genie). If you searched “9 volt battery for garage door keypad”, this is what you’re after.

Tip: Our tool lists the exact part under Battery. If your brand supports battery backup garage door openers (Chamberlain/LiftMaster MyQ, for example), that’s a separate large pack inside the opener head—different from the handheld remote battery.

Garage opener battery replacement (quick guide)

If you’re seeing “Remote range is short,” “Key not detected,” or the LED dims, it’s time for a garage opener battery replacement.

1. Open the case. Remove the key ring. Look for a notch; use a plastic pry tool or coin.
2. Note polarity. Take a quick photo so you can match the + / – on the new cell.
3. Replace the battery. Avoid touching the flat surfaces—finger oils reduce contact. Use CR2032/CR2016/CR2450 or 23A as specified.
4. Close and test. The LED should blink strongly and the door or gate should respond on the first press.

If your remote still doesn’t work after a fresh cell, try re-adding it:

• Chamberlain / LiftMaster (Security+ / MyQ): press Learn on the opener, then press the remote button. (Searches: “chamberlain garage door opener battery replacement”, “liftmaster garage opener battery replacement” often involve this step.)
• Genie (Intellicode): press Learn/Program on the head unit, then the remote.
• Hörmann BiSecur: enroll via the PRG button, or clone from a working BiSecur remote.
• Nice, CAME, FAAC, BFT, Marantec, Linear: add the transmitter in the receiver’s memory; some models support remote-to-remote cloning.

Gate remote battery replacement

For gate remote control battery changes (Nice FLO2R, CAME TOP432NA, FAAC XT2, BFT MITTO, Centurion, etc.):

• The process mirrors garage remotes: open → swap the CR2032 or 23A → re-enroll if needed.
• If your search is “gate remote battery size” and the remote is older, 23A 12V is common; newer rolling-code remotes usually use CR2032.

How to change battery in gate remote:
Open the case at the notch, replace the cell (match polarity), snap closed, then use the receiver’s Learn or follow the brand’s pairing sequence.

Battery backup vs. remote batteries

Phrases like garage door openers with battery backup or garage opener battery backup refer to a large rechargeable pack inside the opener that keeps the door working during power outages. It’s unrelated to your handheld remote’s CR2032/CR2016/CR2450 or A23 cell. Check your opener’s manual for the backup part number (e.g., LiftMaster/Chamberlain MyQ systems).

Troubleshooting after a battery swap

• Door won’t move but lights blink: re-program the remote (use the Learn button).
• Only works up close: new battery may be weak or counterfeit; try a reputable brand.
• Keypad issues: most keypads use a 9-volt; replace it and re-enter the PIN. Searching “garage opener keypad battery” or “keypad garage door opener battery” points here.
• Gate remote not working after new battery: re-enroll it to the gate receiver; some boards clear codes after power loss.
• Quick answers
• Do garage openers have batteries? Remotes and keypads do; many operators also offer battery backup modules.
• What’s the garage opener battery size? Check our tool—common sizes are CR2032, CR2016, CR2450, and A23 12V; keypads often use 9-volt.
• Where to buy garage door opener batteries near me? Any big-box store works, but clicking the battery code in our finder opens a ready search online.
