My Buying Guide on Car Key Battery CR2032
When it comes to my car keys, I often overlook the little things that keep them functioning properly. One crucial component that deserves my attention is the battery—specifically, the CR2032 battery. After dealing with a dead key fob a few times, I learned the hard way how important it is to choose the right battery. Here’s my comprehensive buying guide to help you navigate the world of CR2032 batteries for your car key fob.

This small, round lithium coin cell battery is commonly used in various devices, including car key fobs, watches, and calculators. It has a voltage of 3 volts and a diameter of 20mm, which is why it’s named CR2032 (20mm diameter and 3.2mm thickness).

Brand Reputation
I prefer going with reputable brands. Companies like Energizer, Duracell, and Panasonic have a track record of producing reliable batteries. I trust these brands because they offer quality assurance and longevity.

- Remove the Old Battery: I take note of the battery’s orientation before removing it.
- Insert the New Battery: I place the new CR2032 battery in the same orientation as the old one.
- Close the Fob: I snap the fob back together, ensuring it’s secure.
Final Thoughts
In my experience, keeping a spare CR2032 battery on hand has saved me from being stranded due to a dead key fob.
