What type of battery does a Hyundai key fob use?

I have a 2017 i10 car, which is a model made in 2017 with UK specifications.

How do I replace the battery in the key fob? I know it needs a CR2032 battery. Is there anything else I need to do once I’ve put in the new battery, like programming it beforehand?

Most Hyundai vehicles use a CR2032 battery in their key fobs. The CR2032 battery is a 3-volt lithium coin cell battery that is often used in electronic devices such as calculators and watches.

To replace the battery in your i10 key fob you have open the fob, replace the old CR2032 battery with a new one, and close the fob. No reprogramming is necessary it should function immediately. Make sure the polarity is correct.
