Is your 2015 Dodge Dart key fob not working? Before you jump to conclusions about needing to reprogram your key fob, the most common culprit is often just a dead battery. Replacing the battery in your Dodge Dart key fob is a simple and cost-effective fix that you can easily do yourself. This guide will walk you through the process of replacing your 2015 Dodge Dart key fob battery and offer troubleshooting tips if a new battery doesn’t solve the problem.
Step-by-Step Guide to Replacing Your Dodge Dart Key Fob Battery
Most Dodge Dart key fobs, especially those for the 2015 model year, use a CR2032 battery. These batteries are widely available online and at most stores that sell batteries, and they typically cost less than $6. Before you start, it’s a good idea to have a replacement battery on hand.
Here’s how to open your Dodge Dart key fob and replace the battery:
Opening Your Key Fob:
Depending on the design of your Dodge Dart key fob, the opening method can vary slightly.
-
For Newer Dodge Dart Key Fobs: Look for a small, hidden key. This key is usually released by a small button or latch on the fob. Once removed, insert the tip of this key into the designated slot on the key fob casing. Gently twist or pry to separate the two halves of the fob.
-
For Older Dodge Dart Key Fobs: If your key fob doesn’t have a hidden key or a designated slot, inspect the edges of the fob for a small notch or seam. Use a thin, flat object, such as a small flathead screwdriver or a plastic pry tool, to carefully pry open the case at this notch. Be gentle to avoid damaging the plastic casing.
Accessing and Replacing the Battery:
- Open the Case: Once you have separated the two halves of the key fob, carefully open it like a book.
- Locate the Circuit Board and Battery: Inside, you will see a circuit board. The battery is usually located underneath or beside this circuit board.
- Gently Lift the Circuit Board: In many cases, you may need to gently lift the circuit board to get clear access to the battery compartment. Be careful not to detach any components or damage the board.
- Note Battery Orientation: Before removing the old battery, take a moment to observe how it is positioned in the case. Note which side is facing up (+) and down (-). This will ensure you install the new battery correctly.
- Remove the Old Battery: Carefully remove the old CR2032 battery. You might be able to pry it out with your fingertip or the same small tool you used to open the case.
- Install the New Battery: Place the new CR2032 battery into the compartment, ensuring it is oriented in the same way as the old battery (matching the + and – markings).
- Close the Key Fob Case: Carefully align the two halves of the key fob case and snap them back together until they are securely closed.
Testing Your Key Fob:
After replacing the battery and reassembling your key fob, test its functionality. Press the buttons to lock, unlock, or activate other features of your Dodge Dart. If the key fob now works, you have successfully solved the problem with a battery replacement!
Troubleshooting: What If a New Battery Doesn’t Work?
If you’ve replaced the battery and your 2015 Dodge Dart key fob is still not functioning, there are a few potential issues to consider before assuming you need key fob programming:
- Battery Contact Issues: Double-check that the battery is correctly seated in the compartment and that the metal contacts are clean and making good contact with the battery. Sometimes, slight adjustments to the battery position can make a difference.
- Incorrect Battery Type: Although Dodge Dart key fobs typically use a CR2032 battery, it’s worth double-checking your owner’s manual or the old battery itself to confirm you are using the correct type.
- Key Fob Damage: If the key fob has been dropped, exposed to moisture, or otherwise damaged, internal components might be faulty. In this case, battery replacement alone won’t fix the problem.
- Receiver Issues: In rare cases, the problem might not be with the key fob itself but with the receiver in your Dodge Dart that communicates with the key fob.
When is Key Fob Programming Necessary?
While battery issues are the most frequent cause of key fob problems, there are situations where key fob programming or replacement might be required:
- New Key Fob: If you have purchased a new, unprogrammed key fob, it will need to be programmed to your 2015 Dodge Dart to work with your vehicle’s security system.
- Lost Key Fob and Replacement: If you have lost your original key fob and are using a replacement, programming might be necessary, especially if it’s not a direct, pre-programmed replacement.
- System Malfunction: In some instances, issues with your car’s immobilizer or remote entry system might require reprogramming of the key fobs.
Understanding Key Fob Types
To better understand your Dodge Dart key fob, it’s helpful to know the different types of key fobs available:
- Standard Remotes: Basic remotes with lock, unlock, and sometimes panic buttons.
- Flip Keys: Remotes with a physical key that folds out.
- Remote Heads: Remotes with a permanently attached, non-retractable key blade.
- Fobik Keys: Key fobs where the key blade is separate and hidden within the fob, not directly connected.
- Smart Keys: Advanced remotes often associated with push-to-start ignition and proximity features.

However, starting with a simple battery change can often save you time and money.
