Battery – 2025
View part →
Remote batteries in the sizes garage door handsets actually use, opener light globes, and the lubricants that belong on a garage door — silicone and grease, plus general-purpose spray for the jobs they are not suited to.
Remote handsets use a small range of odd batteries — A23, 2025 and 476A cover most of them — and a flat one is the single most common reason a remote 'stops working'. It is always worth changing before assuming the handset has failed.
Use the right lubricant. Silicone spray is what belongs on rollers, hinges and tracks: it does not attract dust, which matters in Perth because a sandy, oily track wears faster than a dry one. Grease is for the torsion shaft bearings and the opener's drive.
What does not belong on a garage door is a general degreasing spray used as a lubricant. It displaces water and frees a seized part briefly, then dries out and leaves the joint drier than it started.
Opener globes are usually a low-wattage 24V type specific to the motor, not a household bulb. Fitting an oversized globe can interfere with the remote receiver.
Most take an A23, a 2025 coin cell or a 476A depending on the brand and age. Open the back of the handset and read the code off the existing cell — it is printed on the battery itself.
Silicone spray on rollers, hinges and tracks, and grease on the torsion shaft bearings. Avoid using a general-purpose water-displacing spray as a long-term lubricant — it dries out and leaves the joint worse off.
Usually not. Most openers take a specific low-voltage globe, and an incorrect one can interfere with the remote receiver as well as fail early.
