Car keys are essential for starting your vehicle, and when the battery in your key fob dies, it can be a frustrating experience. You may find yourself unable to unlock your car doors or start the engine. Luckily, replacing the battery in your car key is a relatively simple task that you can often do yourself. This guide will walk you through the process step-by-step.
Identifying Your Car Key Battery Type
The first step is to determine the type of battery your car key uses. This information is usually printed on the back of the key fob or in your car’s owner’s manual. Most car keys use a small, round, button-cell battery, commonly known as a CR2032 or CR2025 battery.

- Small screwdriver or tool: This is typically needed to open the key fob.
- A pair of tweezers: This is optional but can be helpful for carefully removing the old battery.
