Quick Summary: The key fob battery for your Dodge Journey is a tiny CR2032 coin cell. Replacing it is a simple DIY task that restores your keyless entry and remote start functions. This guide shows you how, ensuring you power up your convenience easily and safely.
Dodge Journey Key Battery: Essential Power for Your Fob
Ever had your Dodge Journey key fob suddenly stop working? That moment when the unlock button does nothing, or your auto start feature won’t kick in, can be a real hassle. It usually means the small battery inside your key fob has run out of juice. Don’t worry, this is a super common issue, and the fix is much simpler (and cheaper!) than you might think. You don’t need to be a car whiz to get your key fob powered up again. This guide will walk you through exactly how to find the right battery, swap it out safely, and get back to enjoying all the convenience your Dodge Journey key offers. Let’s power up your key!
Understanding Your Dodge Journey Key Fob
Your Dodge Journey key fob is a small, powerful device that lets you interact with your car without even touching it. It’s designed for convenience, featuring buttons for locking, unlocking, opening the trunk, and often for the panic alarm and remote start. Inside this compact unit, a small, flat, coin-shaped battery provides all the necessary power for these functions.
These batteries are designed to last a good while, typically between 1 to 3 years depending on how often you use the fob and the quality of the battery. When it starts to die, you’ll notice the range decreases, meaning you have to be closer to your car for it to respond. Eventually, it will stop working altogether.
Why Does the Key Fob Battery Die?
Several factors contribute to the eventual demise of your key fob battery:
- Age: Batteries have a natural lifespan. Over time, their chemical components degrade, reducing their ability to hold a charge.
- Usage: Frequent use of the fob’s buttons, especially functions like remote start or repeated locking/unlocking, will drain the battery faster.
- Environmental Factors: Extreme temperatures, both hot and cold, can impact battery performance and longevity.
- Battery Quality: Cheaper, lower-quality batteries might not last as long as reputable brands.
Identifying the Right Battery for Your Dodge Journey Key Fob
The most crucial step in replacing your key fob battery is ensuring you have the correct type. For most Dodge Journey models, the standard battery is a:
CR2032 3-Volt Lithium Coin Cell Battery
This is a very common battery size found in many remote key fobs, watches, and small electronic devices. You can usually find the exact battery size printed on the old battery itself once you open the fob, which is a good backup if you’re unsure. Don’t assume any coin cell will work; ensure it’s a CR2032.
Where to Buy Dodge Journey Key Fob Batteries
You have several options for purchasing a replacement battery:
- Auto Parts Stores: Shops like AutoZone, O’Reilly Auto Parts, or Advance Auto Parts usually stock CR2032 batteries.
- Electronics Stores: Best Buy and similar retailers will have them in their battery sections.
- Supermarkets & Big Box Stores: Major retailers like Walmart or Target often carry them in their electronics or battery aisles.
- Online Retailers: Websites like Amazon, eBay, or direct battery suppliers offer CR2032 batteries, often in multi-packs which can save money.
When buying, consider reputable brands for better reliability and longevity. Brands like Duracell, Energizer, or Panasonic are excellent choices.
Quick Tip: Invest in a Multi-Pack
Since key fob batteries are relatively inexpensive, especially when bought in multi-packs, it’s wise to keep a spare or two on hand. This way, when your other key fob or a family member’s car key needs a refresh, you’ll be prepared.
How to Replace Your Dodge Journey Key Fob Battery: Step-by-Step
Replacing the battery in your Dodge Journey key fob is a straightforward process. We’ll break it down into simple steps. Most Dodge Journey fobs can be opened without special tools, but having a small flat-head screwdriver or a plastic pry tool is helpful.
Tools You’ll Need:
- Replacement CR2032 battery
- Small flat-head screwdriver or plastic pry tool
- A soft cloth (optional, to prevent scratches)
Step 1: Locate the Seam on Your Key Fob
Examine your key fob. You’ll notice there’s a seam running around its edge. This is where the two halves of the fob casing meet. Some fobs might have a small notch or indentation, specifically designed to help you open it.
Step 2: Gently Pry the Fob Open
If there’s a notch, carefully insert the tip of your small flat-head screwdriver or plastic pry tool into it. Twist gently or wiggle the tool to create a small gap. You can then slide the tool along the seam, applying light pressure, to separate the two halves of the fob. Be patient and don’t force it, as you don’t want to break the plastic casing.
If there isn’t a specific notch, find the most accessible part of the seam and carefully insert your tool. The idea is to create enough leverage to pop the plastic clips holding the two halves together.
Step 3: Remove the Old Battery
Once the fob is open, you’ll see the circular battery nestled in a small compartment. It’s usually held in place by a small metal clip or simply by friction. Carefully note which side of the battery is facing up (usually the positive ‘+’ side) before you remove it. You can use your fingertip or the tip of your screwdriver to gently pry the old battery out.
Step 4: Insert the New CR2032 Battery
Take your new CR2032 battery. Make sure the positive (+) side is facing the same direction as the old battery (typically upwards, towards the circuit board). Gently place the new battery into the compartment. It should fit snugly. If it doesn’t seem to fit easily, double-check that you have the correct battery and that it’s oriented correctly.
Step 5: Reassemble the Key Fob
Carefully align the two halves of the key fob casing. Press them together firmly until you hear or feel the clips snap back into place. Ensure there are no gaps around the seam, indicating it’s properly sealed.
Step 6: Test Your Key Fob
With the fob reassembled, test all its functions. Try locking and unlocking your Dodge Journey. If you have remote start, test that feature as well. If everything works, congratulations! You’ve successfully replaced your key fob battery.
Troubleshooting Test Results
If your key fob still isn’t working after replacing the battery:
- Check Battery Orientation: Ensure the positive (+) side of the battery is correctly positioned.
- Inspect for Damage: Look for any obvious damage to the fob’s internal components or the battery contacts.
- Try Another New Battery: Although rare, the new battery itself could be faulty. Try a different one.
- Clean Contacts: Gently clean the metal contacts inside the fob with a pencil eraser or a dry cotton swab.
- Consider a Professional: If persistent issues arise, the fob itself might be damaged, or there could be an issue with your car’s receiver. A dealership or automotive locksmith can assist.
Maintaining Other Essential Batteries
While we’re talking about batteries, it’s good to remember that your Dodge Journey relies on other power sources to keep running smoothly. The car battery, in particular, is the heart of your vehicle’s electrical system.
The Dodge Journey Car Battery
Unlike the tiny fob battery, your car uses a much larger, heavy-duty car battery. This battery is responsible for starting your engine and powering all your vehicle’s electrical components when the engine isn’t running.
Signs of a Failing Car Battery:
- Slow engine crank
- Clicking sound when trying to start
- Dim headlights or interior lights
- Warning lights on the dashboard (e.g., battery symbol)
- Swollen or leaking battery case
- Old age (typically 3-5 years for a car battery)
If you suspect your car battery is weak, it’s best to have it tested. Most auto parts stores offer free battery testing. Keeping your car battery terminals clean and free of corrosion can also help extend its life.
For more information on car battery maintenance and replacement, you can refer to resources like those provided by the BatteryStuff website, which offers detailed guides and product information for various automotive batteries.
Other Power Sources to Consider
Beyond your car and key fob, modern life relies heavily on portable power:
- Phone Batteries: These are rechargeable and have a limited lifespan, typically lasting 2-3 years before significant capacity loss.
- Power Banks: Portable chargers for your devices. Keeping them charged and avoiding extreme temperatures helps them last longer.
- Chargers (Phone & Device): Using reputable chargers and cables is crucial for safe and efficient charging. Damaged chargers can pose a fire risk.
Just like your key fob battery, these smaller batteries and power accessories require attention to ensure they function when you need them most.

FAQ: Your Questions About Dodge Journey Key Fob Batteries Answered
Here are some common questions people have about their Dodge Journey key fob batteries.
Q1: My key fob isn’t working at all. Is it definitely the battery?
A: In most cases, a completely unresponsive key fob points to a dead battery. However, it could also be due to physical damage to the fob or a problem with your car’s receiver. But the battery is by far the most common culprit.
Q2: How do I know if my Dodge Journey needs a new key fob battery?
A: Signs include a reduced range for your remote functions, needing to be very close to the car for it to respond, and eventually, the buttons not working at all. Sometimes, if your car has a dashboard indicator, it might hint at a low fob battery, though this is less common.
Q3: Can I use a different type of battery besides a CR2032?
A: It’s strongly recommended to only use the specified CR2032 battery. Using a different voltage or size can damage the key fob’s internal electronics and prevent it from working correctly, or even permanently break it.
Q4: How long should a new key fob battery last?
A: A new CR2032 battery typically lasts between 1 to 3 years. This depends heavily on how often the fob is used, the environmental conditions it’s exposed to, and the quality of the battery itself. Frequent use of functions like remote start can shorten its lifespan.
Q5: What should I do if my key fob still doesn’t work after changing the battery?
A: First, double-check that the new battery is inserted correctly with the positive (+) side facing the right way. Ensure the battery contacts inside the fob are clean. If it still fails, try a brand-new battery from a different pack or brand, as the new one could be faulty. If all else fails, the key fob itself might be damaged, and you may need to consult a dealership or an automotive locksmith for repair or replacement.
Q6: Is it safe to replace the key fob battery myself?
A: Yes, replacing the key fob battery is a very safe DIY task. The process involves no dangerous chemicals or high voltages. Just be careful not to force the fob open and damage the plastic casing. Always handle small batteries responsibly, keeping them away from children and pets.
Q7: Where can I find the battery type if I can’t find the old one?
A: The most reliable way is to consult your Dodge Journey owner’s manual. It should specify the exact battery type needed for your key fobs. If you don’t have the manual, a quick online search for “Dodge Journey key fob battery type” or checking reputable auto parts websites that catalog parts by vehicle year and model will usually give you the correct information (which for most is the CR2032).
