Different Jeep models have slightly different key fob designs, but the battery replacement process is generally similar.

Locating the Right Battery
Before starting the process, it’s important to identify the correct battery type for your Jeep key fob. The most common battery type is the CR2032, a small, circular, lithium battery readily available at most stores. However, some Jeep models may use different batteries. Refer to your owner’s manual for the correct battery type for your specific Jeep model. Using the wrong battery can damage your key fob.
Gathering Your Tools
You’ll need a few simple tools for the job. A small flathead screwdriver or a similar prying tool is usually sufficient to separate the key fob halves. Some key fobs have a small release button or slot that you can use instead of a screwdriver.
