LIR2032 battery

What exactly is an LIR2032?

It’s a rechargeable lithium-ion coin cell battery, commonly used in keyless car remotes and fobs. You’ll find it in loads of modern motors – it’s the little round battery tucked inside the key that keeps everything ticking over. Unlike the standard CR2032, this one’s rechargeable, so you’re not constantly buying replacements or chucking out dead batteries. Better for your wallet, better for the planet.

Which cars use them?

Quite a few, actually. The LIR2032 battery is a popular choice for smart keys in brands like:

• BMW
• Mercedes-Benz
• Audi
• Volkswagen
• Porsche
• Hyundai
• Kia
• Mazda
• Lexus

And that’s just for starters. If you’re unsure, just pop open your key fob or check the car manual – it’ll tell you exactly what you need.

Stop the hassle before it starts

If your key’s starting to act up – taking longer to respond or needing a few presses – that’s usually a sign the battery’s on its last legs. Swapping it out for a fresh LIR2032 can save you from getting caught out when you’re in a rush or it’s chucking it down outside.
