Why Is The Jeep Renegade Key Fob Not Detected?
This is one of the most common problems in the world of keyless-entry car keys. Even though the keyless entry in newer Jeep models makes it very convenient to push to start, there are a few reasons why your Jeep key fob is not being detected.
Here are 7 reasons why your key fob might not be detected in your Jeep:
Dead Key Fob Battery
The most typical cause of a failure to of sending signals to the Jeep’s keyless entry system is a faulty or dead battery in the key fob.
If you don’t have a spare fob, the next section has a few helpful tricks which you can use to start the vehicle when the key fob fails.
Faulty Or Damaged Key Fob
Have you dropped your Jeep Renegade key fob on the ground or in water? This is also one of the main causes for the key fob not working as there might have been wires which have become loose or damaged.
If you have previously dropped your Jeep Key fob in water then contact your local service center to examine the internals of the key for electrical faults. If there is significant damage then you might have to get a replacement key fob.
Using The Wrong Key
We all make clumsy mistakes, but check if you have your vehicle’s key fob and not a different one! All key fobs are unique to the vehicle and will not operate with any other car.
Radio Interference or Signal Jammers
If the Jeep Renegade Key fob suddenly stops working, then radio interference could be the culprit. Nearby radar detectors, and anti-theft alarms, may transmit the same frequency as your key fob’s signal and disrupt the vehicle from interpreting the signal.
Also, be very cautious if your key fob stops working in a shopping mall or a crowded area since thieves with signal jammers effectively aim to stop your key fob from working in an attempt that you leave your car unlocked and they can make a getaway.
Worn Out or Weak Jeep Battery
Sometimes the issue lies with your Jeep Renegade itself. If your Jeep’s battery is about to die, it may not respond to the key fob. Charge the Jeep battery and have it assessed or replaced if it’s old.
Programming Fault In Your Key Fob
This usually occurs if your key fob or the car battery dies. You might notice that if you replace the battery the key fob will still show the error of it not being detected. If this occurs then contact a certified locksmith to reprogram your key.
Issue With The Keyless Entry System Or Engine Push-Start Button
A keyless entry system wire malfunction or even a faulty start button are all possible causes as well. Consider getting your Jeep Renegade assessed for possible at a certified service center for father diagnosis and repairs.
How To Fix A Jeep Renegade Key Fob That Is Not Detected?
The Jeep key fob acts as a short-range radio transmitter, sending coded signals to the vehicle’s receiver. By pressing the push-to-start button, the receiver then performs the function of turning the vehicle on. It is not uncommon for the Jeep Renegade to fail to receive signals from the key fob. Let’s take a look at how you can fix it.
Replace The Key Fob Battery
The first thing you should try is to change your Jeep Renegade key fob battery. For the Jeep Renegade, the key fob battery is a CR2032. You can get it here on Amazon.
Here are the steps to replacing your Jeep Renegade key fob battery:
- Using a flathead screwdriver, carefully pry open the Jeep key fob.
- Take the old CR2032 battery out of its housing.
- Place the new CR2032 battery in place.
- Connect the key fob housing by snapping them together.
Clean Your Key Fob
If replacing your key fob battery doesn’t solve the issue, you should clean your key fob. Your key fob may have accumulated dust or dirt over time which might have affected the connectivity of the contacts or transmitters in your remote.
Use a microfiber cloth with some rubbing alcohol to clean the outside of the key fob. Open the key fob as you would when replacing the battery and look for any debris trapped between the contacts of the battery and within the housing. Use a toothpick or cotton bud to clean the inside out well.
Have The Jeep Renegade Battery Checked
If your engine cranks when you start the car and the headlights seem dimmer than usual, the most likely culprit is your battery, which affects your key fob working too. Go to a certified service center to have your Jeep Renegade’s battery assessed or replaced.
Can You Start A Jeep Renegade When The Key Fob Is Not Detected Or Is Dead?
If you have examined your key fob free of any damage and you’ve confirmed that you have the correct key fob, you can start the Jeep using by placing the top of the key fob on the engine start-stop button, maintaining contact for 5 seconds, then use the top of the key fob to press the button until the Jeep Renegade ignition turns on.
It is crucial to maintain contact with the button for a full 5 seconds, otherwise, this might not work!
The Jeep Renegade owner’s manuals for the years 2014 to 2022 mentions that: “if the key fob is next to a mobile phone, laptop, or other electronic device, the key fob’s wireless signal may not be detected by the Jeep Renegade keyless-go system, preventing the keyless-go system from starting your Jeep Renegade.”
This is only a temporary “fix” until you replace the key fob battery or one of the solutions mentioned above.
The lock and unlock buttons on the remote still won’t work with a dead key fob battery

I think the program in the key fob is bad but if it’s under warranty they may not charge me but if they do I know it will be $200 bucks because of diagnostics they the dealer are way overpriced for a less than 10 min test ripping off the public very bad and greedy corporate corruption, they all do it and get away with it we should all boycotting the dealers if you can or get small clams court to show impractical over charges for work if many of us people do this that may stop the lawlessness services.
