What Size Battery Does a Jeep Key Fob Take?

Knowing what size battery your Jeep key fob takes is crucial for keeping your vehicle accessible.

This guide will walk you through everything you need to know about Jeep key fob batteries, from identifying the correct size to replacing it yourself.

Identifying the Right Jeep Key Fob Battery Size

Different Jeep models and even different model years can use different key fob batteries. The most common sizes are CR2032 and CR2450, but it’s essential to confirm the correct size for your specific vehicle. Your owner’s manual is the best place to find this information. Look for the section on “Keys” or “Keyless Entry.” If you don’t have your owner’s manual, you can often find this information online through Jeep’s website or reputable automotive forums.
