When Is It Time to Replace the Jeep Compass Key Fob Battery?

Your key fob battery powers all of the wireless functions, including locking and unlocking the doors and trunk from a distance. It also enables the “push to start” ignition in newer Jeep Compass models.

Over time, as the battery wears down, you’ll notice certain telltale signs that it’s time for a replacement:

  • Decreased range – If you have to be right next to the vehicle for the key fob to work, this is the #1 sign your battery is running low. Most fobs have a range of 50-100 feet when the battery is fresh.
  • Intermittent functionality – Sometimes your key fob works, sometimes it doesn’t. This intermittent performance indicates the battery is on its last legs.
  • Key fob not locking/unlocking doors – If pressing the lock/unlock buttons doesn’t engage the locks, low battery is likely the culprit.
  • Flashing low battery indicator – Some Jeep Compass fobs have a small LED light that will flash red when the battery level is critically low. Pay attention to this visual indicator.
  • No light when pressing buttons – In addition to the functions not working, the typical LED flash when you press a button may not light up at all.

Under normal use, the typical lifespan of a Jeep Compass key fob battery is 1-2 years before needing replacement. Extreme temperatures can shorten battery life.

You’ll want to replace the battery proactively once you notice any degradation in performance, rather than waiting until the key fob stops working altogether. The longer you wait, the higher the risk of getting stranded with non-functional keys.

Pay attention to the signs, and don’t let a $3 battery drain cause headaches and hassles!

What Type of Replacement Battery Does the Jeep Compass Key Fob Use?

For almost all key fob applications, including the Jeep Compass, the required battery is a small CR2032 coin cell battery.

The CR2032 is one of the most ubiquitous batteries used in small electronics like key fobs, watches, and thermometers. It provides the ideal power-to-size ratio to enable the wireless functionality of the key fob in a compact form factor.

When purchasing a replacement CR2032 battery, there are a few options:

  • Brand name batteries like Energizer, Duracell, or Panasonic are reliable picks.
  • Generic CR2032 batteries are cheaper and work just fine, as key fobs don’t draw much power.
  • Buying in multi-packs is the most cost effective if you need to replace batteries in multiple key fobs.

No need to overpay for specialty batteries – the standard CR2032 coin cell is all you need to revive your Jeep key fob.

Gather Necessary Tools and Supplies

Replacing the battery in your Jeep Compass key fob only requires a few simple tools and supplies:

  • New CR2032 coin cell battery – It’s a good idea to buy 2-3 new batteries in case one is faulty or to prepare for future replacements. Just a few bucks each.
  • Small Phillips head screwdriver – This is used to pry open the key fob casing to access the internal circuit board and battery.
  • Clean, dry cloth – For wiping away any fingerprints or dirt from the circuit board as you handle it.

And that’s it! With just those basic items, you’ll be able to safely open the key fob, swap out the battery, and reassemble it.

No need for soldering irons, glue, or specialized tools. The simple design of most key fobs makes battery replacement a quick 5 minute job.

Before you get started, inspect your key fob for any screws that may be used to hold the casing together. Some fobs use tiny screws instead of snap closures. So have a small precision screwdriver on hand just in case.

Now let’s go over the step-by-step process!

Step 1 – Locate the Key Fob Casing Opening

Examine the sides and edges of your Jeep Compass key fob for a small notch or slot that opens the casing.

It may be on the side, or on the back/edge between the upper and lower portions of the casing. Refer to your owner’s manual if you can’t find it.

This notch allows you to wedge in a small screwdriver to pry open the casing and access the internal circuit board.

Gently insert the screwdriver tip into the notch and wedge it open a bit. There will likely be snaps holding the two case halves together. You may need to run the screwdriver along the seam to release all of the snaps before it will open.

Start at the notch, and slowly work your way around, taking care not to damage the plastic. Once you release the final snap, the two halves should separate allowing you access to the circuit board inside.

Step 2 – Carefully Open the Key Fob Casing

With the casing unlocked, the next step is to open it up. Slowly and gently pull the two case halves apart, creating enough space to see the circuit board inside.

Be careful of any ribbon connectors that may join the two halves electrically. These pull apart with gentle wiggling.

Fully open the casing while ensuring the circuit board and electrical contacts don’t get damaged. It’s a good idea to photograph the opened key fob from multiple angles so you know how everything lines up during reassembly.

Your Jeep Compass key fob battery will be mounted in a circular plastic holder clipped into the circuit board.

Now that you’re inside, it’s time to remove the depleted battery and put a fresh one in its place.

Step 3 – Remove the Old Battery from the Key Fob

The CR2032 battery mounts into a plastic holder that clips onto the circuit board. To remove it, you’ll need to un-clip it from the holder.

First, locate the battery holder on the circuit board. There are typically thin metal clips on either side that clasp onto the edge of the battery.

Then, use your screwdriver to gently wedge underneath one side of the battery and pry it upwards to un-clip it from the holder.

Sometimes a bit of wiggling side to side can help release the clasp. Be patient and work at it carefully. Never force anything or damage could occur.

Once you get one side unclipped, the battery will pop out of the holder. Set the depleted battery aside.

Now the key fob is ready for the fresh CR2032 battery to be installed.

Step 4 – Insert the New CR2032 Battery

To insert the new CR2032 coin cell battery, first identify the positive (+) and negative (-) sides. There may be very small markings molded into the plastic casing.

If not, the negative side is always the flat surface. The positive side has a slight raised bump.

Orient the new battery with positive side facing up, and slide it into the battery holder. Push down gently until it clicks and clasps into both sides.

Visually inspect to ensure the battery is seated flat in the holder and both sides have clipped in properly. If the battery sits crooked, it could lose contact intermittently causing functioning issues.

Reattach any small connectors that may have come loose when opening the casing. Your key fob should now have fresh power!

Step 5 – Reassemble the Key Fob Casing

With the new battery installed, it’s time to reassemble the two case halves.

First, use the clean cloth to gently wipe any smudges or fingerprints off the circuit board. This avoids moisture or dirt being sealed inside.

Align the two casing halves, and then gently press them back together until all of the snaps click into place. This secures the water resistant seal.

Visually inspect the casing for proper closure. Ensure no large gaps are present where water could seep in.

And that’s it – you’ve successfully completed the key fob battery swap!

Now press the lock/unlock buttons to test that the fob powers on and activates your Compass’ locks.

Assuming proper battery orientation, your Jeep key fob range should be restored to max distance once again. Well done!

Troubleshooting Common Jeep Compass Key Fob Issues

In most cases, replacing the CR2032 battery in a Jeep Compass key fob will resolve any functionality or range issues. But occasionally other problems can arise.

Here are some troubleshooting tips for common scenarios:

Key fob still not working after battery replacement

  • Make sure the new battery is properly oriented positive (+) side up in the holder. Even reverse inserting the battery can prevent operation.
  • Try re-pairing or re-programming the key fob to sync it with your Compass. Consult the owner’s manual for how to do this.

Shortened wireless range

  • If range is still shorter than expected, replace the battery again even if recently changed. Some new batteries are faulty or drain faster.
  • Carefully inspect the battery contacts/terminals for any dirt/corrosion which could impede current flow. Clean if needed.

Multiple key fobs not working

  • When multiple Jeep key fobs stop working together, it’s likely that all of their batteries have drained. Replace batteries in all units even if you’re not sure.

Key fob has moisture/water damage

  • If the key fob gets wet, immediately remove battery + dry circuit board thoroughly. Damage may occur. Professional help may be needed.

Physical damage to key fob casing

  • Severe drops can break internal parts. Inspect closely for damage. If the circuit board is damaged, the key fob will need to be replaced or professionally repaired.

Still not working after troubleshooting

  • For any issues persisting after battery replacement and troubleshooting, your best bet is to take the key fob to a Jeep dealership or locksmith for professional service.

While the majority of key fob issues can be resolved with a simple battery replacement, knowing these troubleshooting tips will help get yours working optimally again.

The Pros and Cons of Replacing a Jeep Compass Key Fob Battery

Before you attempt a battery replacement, consider the key pros and cons:
