How to Change a Jeep Renegade Key Fob Battery: Step by Step Guide

Key fobs have become a staple feature connected to any modern-day car, including the Jeep Renegade. These little devices make getting in and out or even starting your Jeep convenient; that is, until their batteries run out. At which point, you’ll have to replace it before you can hop behind the wheel again, but if this is your first time, you might be wondering how to go about this process.

To change the battery on a Jeep Renegade key fob, all you have to do is remove the fob’s internal key, open the fob, and remove the old battery. You can then install the new battery, reassemble the fob, and replace the key for a fully charged and restore fob.

In this article, we will provide a step-by-step guide on how to change the battery in a Jeep Renegade key fob in case you aren’t sure about what tools to use or have other questions regarding this process. As you read, you’ll also learn about key fob-related issues you might be experiencing if your fob still isn’t working properly after installing a new battery.

How Do I Change the Battery In My Jeep Renegade Key Fob?

The Jeep Renegade first started production in 2014 and released in 2015, meaning every model is paired with a key fob.

Older models might house the car’s ignition key inside, whereas newer models are designed to support keyless ignition with the help of a push start and sensor (however, some still house emergency keys inside the fob).

Either way, you can replace any Jeep Renegade key fob battery by yourself using this step-by-step guide regardless of which key fob type you have. For this process, all you’ll need is a flathead screwdriver and a new CR2032, 3-volt battery.

To change the battery in a Jeep Renegade key fob, follow the steps listed below:

  1. Slide the small mechanical latch found on the fob’s exterior to release the interior emergency key
  2. Remove the interior emergency key from the fob
  3. Insert a flathead screwdriver into the emergency key slot
  4. Pry the fob case pieces apart gently with the screwdriver and separate them
  5. Remove the old fob battery
  6. Insert the new battery (make sure the + pole is facing down in the fob)
  7. Replace and snap the fob case pieces shut
  8. Replace the interior emergency key

Once you’ve installed a new battery successfully into your Jeep Renegade key fob, test the fob to ensure it is working properly. If not, you’ll want to repeat the process and confirm that the battery is firmly in place with the positive pole facing down.

How Long Should A Jeep Renegade Key Fob Battery Last?

Knowing how long your Jeep Renegade’s key fob battery should last can help you determine if they’re running out prematurely, potentially indicating a more serious problem in need of attention.

While the lifespan of a key fob’s battery can vary depending on factors such as brand, frequency of use, and age, to name a few, on average, they should last anywhere between three to four years.

Two is reasonable if you use the fob frequently and/or purchased a low-quality battery, but if you find yourself replacing it sooner than that, then you might want to have your fob checked out by a professional. 

Why is My Jeep Renegade Key Fob Battery Draining So Fast?

If you find that your Jeep Renegade key fob battery is draining faster than usual, there are a few possible explanations.

The most common reason your renegade key fob battery is draining is that you are storing your key fob too close to your Jeep Renegade. Car key fobs are each programmed to your specific vehicle, allowing them to communicate with one another through electrical signals once your key fob is within range.

Therefore, if you tend to leave yours, or even a spare, key fob inside or hanging near your Jeep Renegade, then it is constantly sending signals to your car, resulting in gradual but constant drain on its battery.

Because of this, it is best to keep your key fob stored far from your vehicle if you want to prolong its battery life.

Another potential explanation could be that one or more buttons on your key fob are stuck in an activated position. Even if your key fob isn’t near your car, having these buttons engaged can gradually drain your battery as well.

What Can I Do If My Jeep Renegade Key Fob Is Lost Or Broken?

If you lose or damage your key fob, you might be wondering where to find a replacement. The good news is that there are a few different options available to you.

First, you can check with your local dealership or auto store. They should be able to provide you with a new key fob for your specific make and model of car. However, this can be a bit of a hassle, and it may also be more expensive than other options.

Alternatively, you can purchase a replacement key fob online. There are plenty of reputable sellers who offer high-quality key fobs at a fraction of the cost of dealership replacements.

Finally, if you’re feeling particularly handy, you can even try to program a new key fob yourself. While this option requires a bit more know-how, it can save you a lot of money in the long run.

Whichever option you choose, don’t let a lost or damaged key fob ruin your day. With a little bit of effort, you should be able to find a suitable replacement without too much trouble.
