The 2019 Jeep Cherokee is a popular SUV known for its ruggedness and versatility. However, like any other vehicle, it can experience issues, and one common problem is with the key fob. Whether your key fob isn’t working at all, has a decreased range, or is sending intermittent signals, this article will provide you with a comprehensive guide to understanding and resolving these issues.
Common 2019 Jeep Cherokee Key Fob Issues
Before we delve into the solutions, let’s identify some common key fob problems:
- Key Fob Not Working at All: This is often indicated by the vehicle not responding to any button presses on the key fob.
- Decreased Key Fob Range: You might find yourself standing closer to your Cherokee than usual to lock or unlock the doors.
- Intermittent Key Fob Signals: The vehicle may respond inconsistently to key fob commands, working sometimes but not others.
What Causes a Jeep Cherokee Key Fob to Stop Working?
Understanding the potential reasons behind key fob malfunctions can help you pinpoint the source of the problem:
- Dead Key Fob Battery: This is the most frequent culprit. Like any battery-operated device, a depleted battery renders the key fob useless.
- Key Fob Programming Issues: Over time, the programming linking your key fob and your Cherokee’s security system might become corrupted, leading to communication failures.
- Internal Key Fob Damage: Physical damage from impact, water exposure, or wear and tear can disrupt the key fob’s internal components.
- Antenna Problems (Vehicle-Side): A malfunctioning antenna in your Jeep Cherokee can hinder its ability to receive signals from your key fob.
- Issues with the Vehicle’s Wireless Control Module (WCM): The WCM acts as the brain for your Cherokee’s keyless entry system. Any issues with this module can lead to key fob problems.
Troubleshooting and Solutions for Your 2019 Jeep Cherokee Key Fob
Now, let’s explore solutions for your key fob troubles:
1. Replace the Key Fob Battery
Often, the simplest solution is the right one. A dead battery is the most common reason for key fob malfunction. Here’s how to replace it:
- Identify the Battery Type: The 2019 Jeep Cherokee key fob typically uses a CR2032 battery. You can find these at most hardware and electronics stores.
- Open the Key Fob: Look for a small release button or notch on your key fob. Press this button while gently separating the two halves of the fob.
- Remove the Old Battery: Carefully pry out the old battery from its compartment. Note the battery’s orientation for correct replacement.
- Insert the New Battery: Place the new CR2032 battery into the compartment, ensuring it matches the orientation of the old battery.
- Reassemble the Key Fob: Align the two halves of the key fob and press them together until you hear a click, indicating they are securely closed.
2. Reprogram Your Jeep Cherokee Key Fob
If replacing the battery doesn’t solve the problem, you might need to reprogram your key fob. There are two ways to do this:
Method 1: DIY Reprogramming
Some Jeep Cherokee models allow for DIY reprogramming. The exact procedure may vary, so consult your owner’s manual for specific instructions.
Method 2: Professional Reprogramming
If you’re unable to reprogram the key fob yourself or if the DIY method doesn’t work, you’ll need to visit a qualified automotive locksmith or your Jeep dealership for professional reprogramming.
3. Inspect Your Key Fob for Damage
Carefully examine your key fob for any signs of physical damage, including cracks, loose buttons, or water damage. If you find any significant damage, it’s best to replace the key fob altogether.
4. Check the Vehicle’s Antenna and WCM
While less common, problems with your Cherokee’s antenna or WCM can also cause key fob issues. These diagnoses require specialized equipment and expertise, so it’s recommended to take your vehicle to a trusted mechanic or your dealership for inspection and repair.
Preventing Future Key Fob Issues
Here are a few tips to prevent key fob problems in the future:
- Regular Battery Replacement: Replace your key fob battery every 2-3 years as preventative maintenance, even if it seems to be working fine.
- Keep Your Key Fob Dry and Protected: Avoid exposing your key fob to water or extreme temperatures, and store it in a protective case when not in use.
- Handle Your Key Fob with Care: Dropping your key fob frequently can cause internal damage.
