  1. Slide the small mechanical latch found on the fob’s exterior to release the interior emergency key

What Kind of Battery Does My Jeep Compass Key Fob Take?

The jeep compass key fob uses a certain type of battery.

They use the CR2032, 3V lithium button cell battery. This type of battery is also known as a coin cell battery, due to its small size and round shape.

These batteries measure 20mm in diameter and 3.2mm in height and can be purchased through any brand for an affordable price of $1.20-$3.13 per battery.

Where Can I Buy a New Battery For My Jeep Compass Key Fob?

Luckily, CR2032, 3V lithium button batteries are fairly common and can be found in a wide range of locations.

Some include:

  • Grocery stores
  • Home improvement stores
  • Automotive shops
  • Online retail stores (ex. Amazon)
  • Department stores

If your Jeep Compass needs any repairs or services, you can also ask the mechanic or dealership employee if they would replace your key fob’s battery as well.

How Long Should a Jeep Compass Key Fob Battery Last?

It’s highly likely that you’ll have to replace the battery in your Jeep Compass key fob at least once throughout the years. However, knowing how long these batteries should last can be helpful in determining if they are running out prematurely, potentially indicating a more serious problem with your fob.

On average, they should last anywhere between three to four years. However, the lifespan of a key fob’s battery can vary depending on factors such as:

  • Brand
  • Frequency of use
  • Age

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

Make Sure Not to Keep Your Key Fob Inside Your Jeep

The only other factor that might be at play here is if you generally leave your key fob inside your Jeep Compass or hanging nearby when the car is not in use.

This might cause the key fob to continually send signals to your car, since it is in range, 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.
