The jeep key fob is a device that allows you to remotely control your jeep. It can be used to lock and unlock the doors, start the engine, and even open the trunk. Jeep key fobs are a great way to make sure that your jeep is always secure, and they can also make life a lot easier. If you’ve ever been stranded in the middle of nowhere with a dead battery, you’ll know how useful a jeep key fob can be.
However, sometimes the Jeep key fob not detected can be a frustrating experience. There are a few different reasons why this may occur, which include a dead key fob battery, loose connection, or faulty Key Fob. Below we will explore each of these possibilities in more depth.

10+ Reasons Why Your Jeep Key Fob not Detected?
Bad Key Fob
In this case, you will need to replace the entire Key Fob. There are a few different things that can cause a key fob to become faulty. The most common cause is physical damage. If your key fob is dropped or hit too hard, it can damage the internal components and cause it to stop working properly. Another common cause of key fob failures is water damage. If your key fob gets wet, it can shorts out the electronics and render it unusable.
If you’ve recently changed your Jeep’s key fob, it’s possible that you’re using the old one by mistake. The new key fob might not be programmed yet, so it’s not being detected. Make sure you’re using the correct key fob and that it’s been properly programmed before assuming there’s another problem.
Another possibility for why your Jeep key fob is not being detected is due to a loose connection. To check for this, you will need to open up the key fob and check the connections. Make sure that all of the wires are securely connected and that there are no damaged wires. If everything looks good, then test the key fob again to see if it is working. If it is still not working, then you may have a faulty Key Fob.
Dead Key Fob Battery
When your key fob battery dies, it can prevent your Jeep from starting. The key fob relies on a battery to communicate with the Jeep’s computer system. When the battery is dead, the Jeep does not receive the signal it needs to start. As a result, you may find yourself stranded with a dead key fob and a Jeep that won’t start. In some cases, you may be able to use the emergency key to start the Jeep, but this is not always reliable.
Another possibility is that there’s an issue with the programming of your Jeep key fob. If you’ve recently replaced the battery in your key fob, it might need to be programmed again. This is a relatively simple process that can be done by most Jeep dealerships or locksmiths.
Faulty Door Lock
Sometimes, the door locks can become worn out and will not work properly. Other times, the door locks may be frozen or jammed. If you think that your door lock is the reason why your Jeep key fob not working, then you should try to replace it.
Another possible reason why your Jeep key fob not working is because of radio interference. This usually happens when there are other electronic devices that are near your key fob. Some examples of these devices include cell phones, laptop computers, and even garage door openers. If you think that radio interference is causing your key fob to not work, then you should try to move away from any electronic devices that are close to you.
Jeep Battery Worn Out
If neither of those solutions solves the problem, it’s possible that the battery in your Jeep or car is worn out and needs to be replaced. This is a more common problem in cold weather because the battery doesn’t work as well in cold temperatures. If this is the case, you’ll need to replace the battery in your Jeep or car before your key fob will start working again.
It’s also possible that a fuse has blown in your Jeep. This usually happens when there is an electrical short somewhere in the Jeep. If you think that a fuse has blown, then you should check the fuse box and replace any fuses that are blown.
Broken wire in a key fob
When you press the button on your Jeep key fob, it sends a signal to the car telling it to unlock the door or turn on the engine. If there is a broken wire inside of the key fob, that signal can’t get through and the car won’t respond.
The most common cause of a broken wire in a key fob is simply wear and tear. Over time, the wires can get frayed or stretched, which can cause them to break. Another possible cause is if the key fob is dropped or otherwise damaged.
Misaligned buttons or broken contacts
Another possible reason why your Jeep key fob is not working is because the buttons or contacts are misaligned. This can happen if the key fob is dropped or otherwise damaged. If the buttons or contacts are misaligned, they might not be making a good connection when you press the button. As a result, the signal from the key fob might not be getting through to the car.
How to Fix When Your Jeep Key Fob Not Working
In most cases, the issue is with the battery or the connection between the key fob and the car. Try these quick fixes and you’ll be back on the road in no time!
Replace the Battery
The first thing you’ll want to do is check the battery. Over time, batteries will lose their charge and will need to be replaced. If your Jeep key fob is more than a few years old, it’s probably time for a new battery. Simply pop open the key fob and replace the old battery with a new one. Once you’ve done that, try starting your car. If the problem persists, move on to fix #2.
Clean the Connection Points
If replacing the battery didn’t do the trick, then it’s probably an issue with the connection between the key fob and the car. Start by taking a look at both the key fob and car for any dirt or debris that could be causing interference. Once you’ve found the source of the problem, clean it off with a soft cloth. You may also want to use a can of compressed air to blow out any dust or debris that’s lodged in hard-to-reach areas. Once you’ve done that, try starting your car again. If your key fob still isn’t being detected, move on to fix #3.
Reset Your Key Fob
If you’ve tried both of the above fixes and you’re still having problems, then it’s time to reset your key fob. This is a relatively simple process that just requires you to hold down a button on your key fob for a few seconds. Consult your owner’s manual for specific instructions on how to reset your particular model of Jeep key fob. Once you’ve done that, try starting your car again. In most cases, this will solve the problem and get you back on the road in no time!
Reprogram Your Key Fob
If the issue is with your key fob, you may need to reprogram it. To do this, you will need to find the instructions in your owner’s manual. Once you have the instructions, follow them carefully. If you still can’t get your key fob to work, you may need to take it to a professional to have it done.
Replace the Fuse
If the fuse that controls your key fob has blown, then that could be the reason why it’s not working. To replace the fuse, you’ll need to locate the fuse box and find the fuse that corresponds to your key fob. Once you’ve found the fuse, simply remove it and replace it with a new one. Once you’ve done that, try starting your car again. If the problem persists, you may need to take your car to a professional for further diagnosis.
If the Jeep key fob not working, it could be because the signal is being blocked. This can happen if the key fob is near other electronic devices or if it’s in a pocket or purse. To fix this, simply move the key fob away from other electronic devices and make sure it’s not in a pocket or purse. Once you’ve done that, try starting your car again.
Try changing out your Jeep key fob receiver
If you have tried all of the above fixes and your key fob still is not working, you may need to replace the receiver. The receiver is what picks up the signal from the key fob and sends it to the car. To replace the receiver, you’ll need to take your car to a professional. Once they’ve replaced the receiver, try starting your car again.
Readjust Button Alignments and Contacts
If the buttons on your Jeep key fob not working, it could be because they are misaligned or the contacts are dirty. To fix this, start by taking a look at the buttons and make sure they are all lined up correctly. Once you’ve done that, use a can of compressed air to blow out any dirt or debris that might be blocking the contacts. Once you’ve done that, try starting your car again.
Replace Key Fob
If you’ve tried all of the above fixes and your key fob still is not working, then you may need to replace it. You can purchase a new key fob from your local Jeep dealership or an online retailer. Once you have the new key fob, follow the instructions in your owner’s manual to program it. Once you’ve done that, try starting your car again.
How to Start Your Jeep Cherokee If the Key Fob Is Not Detected
Starting your Jeep Cherokee should be a simple process – just insert your key fob into the ignition and press the start button. But what do you do if your key fob isn’t detected? Here are a few things you can try to get your Jeep started.
- Check the battery. If your key fob not working, one of the first things you should check is the battery. If it’s low on power, it may not be sending a signal strong enough to be detected by your Jeep. Pop open the back of the key fob and check to see if the battery needs to be replaced.
- Check for metal objects. If you have any metal objects on or near your key fob (e.g., coins, keys, etc.), this could interfere with the signal and prevent your Jeep from detecting the key fob. Try removing any metal objects from your pockets before attempting to start the Jeep again.
- Try starting with the emergency key. Every Jeep comes with two keys – a regular key and an emergency key. The emergency key doesn’t have any of the bells and whistles of the regular key (e.g., remote start, remote unlock, etc.), but it should still be able to start your Jeep if necessary. Insert the emergency key into the ignition and see if that does the trick.
- Call a tow truck or locksmith. If you’ve tried all of the above and you’re still having trouble starting your Jeep, it’s time to call for help. A tow truck or locksmith will be able to help you get your Jeep started so you can be on your way.

How Does Jeep Key Fob Work?
For Jeep owners, the key fob is an essential component to the driving experience. This gadget not only unlocks and locks your doors and starts the engine, but it also has a panic button in case of emergency. But how does this little remote work? Let’s find out.
The key fob for your Jeep uses radio-frequency identification (RFID) technology. This type of technology is what allows you to remotely start your car from afar as well as open and close your doors. When you push the button on your key fob, it sends a signal to a receiver that is located inside your Jeep. That signal is then processed by your car’s computer, which then performs the desired action, whether that be locking or unlocking the doors or starting the engine.
It’s important to note that RFID technology is not just limited to key fobs. In fact, this type of technology is becoming more and more prevalent in our everyday lives. Many credit cards now come with an RFID chip that allows you to simply hold your card up to a reader instead of having to swipe or insert it. Some newer passports also have RFID chips that contain all of your personal information.
Benefits of Key Fobs
While they may seem like a luxury, there are actually quite a few benefits that come along with having a key fob for your Jeep. First and foremost, they provide an extra layer of security for your vehicle. If someone were to try to break into your car, they would not only have to deal with the alarm system, but they would also have to bypass the locking system that is activated by the key fob.
Second, key fobs make it easier to get in and out of your Jeep, especially if you have your hands full. No more fishing around in your pockets or purse for keys! And lastly, jeeps with keyless ignition systems allow you to start your car without ever having to take the key out of your pocket – very convenient on cold winter mornings!
Of course, there are some downsides too. Key fobs can be easily lost or misplaced (which is why it’s always a good idea to have a spare!), and they can be quite expensive to replace if you don’t have insurance. Still, overall they are a great addition to any Jeep!
Do All Jeeps Come With A Key Fob?
