Understanding Jeep Car Key Battery Types
Before diving into the replacement process, it’s essential to understand the different types of car key batteries used in Jeeps. Jeep models often utilize either CR2032 or CR2016 batteries. These are small, coin-shaped batteries commonly found in electronics and remote controls. The specific battery type for your Jeep will depend on the year, make, and model. You can usually find this information in your owner’s manual or by checking the battery compartment itself.
Identifying Your Battery Type
Here’s a quick guide to help you identify your Jeep car key battery type:
- CR2032: This is the most common type of battery used in Jeep car keys. It has a diameter of 20 millimeters and a thickness of 3.2 millimeters.
- CR2016: This battery is slightly smaller than the CR2032, with a diameter of 20 millimeters and a thickness of 1.6 millimeters.
It’s crucial to use the correct battery size and type for your Jeep. Using an incompatible battery can damage your key fob or prevent it from functioning properly.
