Learning how to change the battery in your Chevrolet key fob is quick, easy, and requires only a few basic tools. Most Chevy key fobs use a CR2032 or CR2450 battery and can be replaced in under five minutes, often without any reprogramming required.
If your Chevrolet key fob is slow to respond, only works up close, or shows a “key fob battery low” warning, it’s likely time for a replacement. Follow this guide to get your key fob working like new again.
What Battery Does a Chevrolet Key Fob Use?
Most Chevrolet key fobs use one of the following batteries:
- CR2032 3-volt battery (common in older models and many standard remotes)
- CR2450 3-volt battery (used in some newer Chevrolet models)
You can confirm the correct battery type by:
- Checking the label inside the key fob
- Looking in your owner’s manual
- Matching the old battery once it is removed
Pro Tip: These batteries typically cost under $5 and are available at hardware stores, pharmacies, and online retailers.
Chevrolet Key Fob Battery by Year
While designs vary by model, battery usage often follows this general pattern:
- Pre-2020 Chevrolet key fobs: CR2032
- 2020 and newer Chevrolet key fobs: CR2450 in many models
Always double-check before purchasing because these batteries are not interchangeable.

- A small flathead screwdriver
