wpgguy said:Hopefully yours is just the battery. I’ve noticed both of mine are fairly intermittent. Sometimes it’ll work, other times I can stand beside the car and nothing happens . I can hammer the buttons and eventually it’ll start responding again after maybe 10-20 seconds of nothing. I havent bothered taking it in, just chalked it up to be possible interference or maybe the Jeep just doesn’t like me.

What Is The Average Lifespan Of A Jeep Compass Key Fob Battery

This is a question that we get all the time here at Jeep Compass Forum, and its one that weve been trying to answer for a while now. The average lifespan of a Jeep Compass key fob battery is about two years. However, there are a few things that can affect this number.

First, lets talk about what a key fob battery is and what it does. A key fob battery is a small, lithium ion battery that is used to power your Jeep Compass key fob. This battery is what allows you to remotely unlock your doors, start your engine, and do other cool Jeep Compass features.

Now, the lifespan of your key fob battery will depend on a few factors. First, how often do you use your key fob? If you use it multiple times a day, then your battery will obviously die faster than someone who only uses it once a week.

Another factor that can affect the lifespan of your key fob battery is the temperature. If you live in a cold climate, your battery will die faster than someone who lives in a warm climate. This is because cold temperatures cause the battery to lose power faster.

Finally, the type of battery you have in your key fob can also affect its lifespan. There are two different types of batteries that are commonly used in key fobs: CR2032 and CR2025. The CR2032 battery is the newer of the two and it has a longer lifespan than the CR2025 battery.

So, if you want your key fob battery to last as long as possible, use it sparingly and keep it in a warm place.

S For Replacing A Jeep Key Fob Battery

Key Fob Battery Replacement | How To | 2020 Jeep Cherokee

Before getting started with replacing your key fob battery, gather the supplies and equipment youll need. Essential items are:

  • A replacement battery
  • A small flat-head screwdriver

Once youve gotten together the items you need, insert the tip of your flat-head screwdriver into the key fob seam by your key ring mount. Press down gently to separate the top and bottom pieces of plastic. Be careful not to twist the screwdriver head because it could break the plastic. In certain Jeep models, youll also need to remove the emergency key before proceeding.

Open the top and bottom pieces. Youll see the old battery, a circuit board, and a rubber keypad. Remove the old battery from the housing.

Take care to note which side of the battery is facing up. Replace the new battery in the same orientation as the old battery. Usually, the negative side of the battery will face down.

Put the circuit board back in the keypad, then replace the keypad. The last step is snapping the two key fob halves, top and bottom, back together.

You wont need to reprogram your key fob if just replacing the key fob battery. However, you can find key fob reprogrammers at auto supply dealers.

  • Press down on the screwdriver to force the key apart at the seam.
  • Remove the battery from the housing.
  • Insert a new CR2032 battery with the negative side down.

  • Snap the two halves together starting at near the key and working to the end.
  • Tools you’ll need to complete this project:

    Wrong Key Fob Programming

    Key fobs are small, portable, and fantastic devices that allow owners to control a vehicle remotely. A fob has two main functions: it must be able to store a security code that provides access to the jeep, and it must transmit that code to the vehicle to unlock the doors.

    So, the key fob is all about programming. If something is wrong with the security code of the vehicle, the whole key fob system is abortive.
