Experiencing a dead key fob for your Jeep Wrangler can be incredibly frustrating. If your Wrangler’s key fob has stopped working or the range has significantly decreased, it’s likely time to replace the key fob battery. This guide will walk you through everything you need to know about replacing your Jeep Wrangler key fob battery, from identifying the correct replacement to completing the installation yourself.
Understanding Your Jeep Wrangler Key Fob
Before diving into the battery replacement process, it’s essential to understand a bit about your Jeep Wrangler key fob. Your key fob is responsible for remotely locking and unlocking your vehicle, activating the alarm system, and even starting the engine in some models.
The key fob relies on a small battery to power these functions. Over time, this battery will naturally drain, requiring replacement. Thankfully, replacing your Jeep Wrangler key fob battery is a simple task that most vehicle owners can easily complete at home in a matter of minutes.
What You Need to Replace Your Jeep Wrangler Key Fob Battery
Replacing your Jeep Wrangler key fob battery is a quick and easy task that requires only a few simple tools:
- New Battery: It’s crucial to get the correct battery for your specific Jeep Wrangler model. Refer to your owner’s manual or look up the information online using your Wrangler’s year and model. The most common battery type for Jeep Wrangler key fobs is the CR2032.
- Small Flat-Head Screwdriver: This will be used to open the key fob casing.
- Plastic Pry Tool (Optional): While a flat-head screwdriver can work, a plastic pry tool helps prevent scratching or damaging the key fob casing.
