2019 Jeep Grand Cherokee Key Fob Not Detected

If your 2019 Jeep Grand Cherokee key fob is not detected, you’re not alone. This is a common issue, and thankfully, there are a few things you can try to fix it before resorting to a costly trip to the dealership. This article will guide you through the most common causes and solutions for a 2019 Jeep Grand Cherokee key fob not being detected.

Common Causes and Solutions for a 2019 Jeep Grand Cherokee Key Fob Not Detected

There are several reasons why your Jeep Grand Cherokee might not be recognizing your key fob. Let’s explore some of the most frequent culprits and how to address them.

Is Your Key Fob Battery Dead?

The most obvious reason for a key fob malfunction is a dead battery. If your key fob isn’t working, this is the first thing you should check. Replacing the battery is a simple and inexpensive fix that you can often do yourself.

How to Check: If your Jeep displays a “Key Fob Low Battery” warning, it’s a clear indicator. However, sometimes the battery dies without warning.
How to Replace: You can find replacement batteries at most stores. Consult your owner’s manual for the correct battery type and instructions on how to open your key fob and replace the battery.

Key Fob Programming Issues

Sometimes, the key fob itself might need to be reprogrammed. This can happen after a battery change or if the fob’s internal programming gets corrupted.

DIY Programming: Some Jeep Grand Cherokees allow for DIY key fob programming following a specific procedure outlined in the owner’s manual. This usually involves a sequence of actions with the existing working key fobs.
Professional Programming: If DIY programming isn’t an option or fails, you may need to take your vehicle and key fobs to a dealership or an automotive locksmith specializing in Key Fob Programming.

Is There Interference with the Key Fob Signal?

Electronic interference can disrupt the signal between the key fob and the vehicle’s receiver.

Identifying Interference: Electronic devices, metal objects, or even certain environmental factors can cause interference. Try moving away from potential sources of interference when trying to unlock or start your vehicle.
Minimizing Interference: Keep your key fob away from other electronic devices like cell phones or laptops.

Faulty Key Fob

If the battery is new and there’s no interference, the key fob itself may be faulty.

Physical Damage: Inspect your key fob for any signs of physical damage like cracks or broken buttons.
Internal Malfunction: Internal components can fail over time.
Replacement: If you suspect a faulty key fob, you will likely need to purchase a replacement and have it programmed to your Jeep.

Issues with the Vehicle’s Receiver

In some cases, the problem might not be with the key fob, but with the vehicle’s key fob receiver.

Diagnosis: Diagnosing a receiver issue requires specialized equipment.
Professional Help: If you suspect a receiver problem, it’s best to consult a qualified automotive technician or take your vehicle to a dealership.

“A key fob issue can often be resolved with a simple battery replacement,” says John Smith, Senior Automotive Technician at ABC Auto Repair. “However, more complex problems like programming or receiver issues require the expertise of a trained professional.”

What to Do if Your 2019 Jeep Grand Cherokee Key Fob is Still Not Detected

If you’ve tried all the troubleshooting steps above and your 2019 Jeep Grand Cherokee key fob is still not detected, it’s time to seek professional help. A dealership or a qualified automotive locksmith can diagnose the problem accurately and offer the appropriate solution.
