Why your Jeep key fob may not be working

Jeeps come with a variety of key fobs. If yours is not working, there are a few things you can do to try and fix the issue. Unfortunately, not all key fobs work interchangeably between different makes and models of Jeeps. If your Jeep does not have an onboard keyless lock or security system, your only option may be to replace the entire key fob assembly. Here are some common reasons why a Jeep’s key fob may not be working:

Incorrect battery
Faulty sensor
The cord connecting the remote to the car might be damaged or lost
The code on the remote might have been changed

Ways to fix a Jeep key fob that’s not working

If your Jeep key fob isn’t working, there are a few things you can do to try and fix the issue. First, check to see if the battery is fully charged. If it’s not, you can try replacing the battery. If that doesn’t work, you can try resetting the key fob by holding down the “Reset” button for five seconds. If that still doesn’t work, you may need to replace the key fob.

How to troubleshoot your Jeep key fob issue

If your Jeep key fob isn’t working, it could be due to a number of different reasons. First and foremost, check the battery level and make sure it’s holding a charge. If you’re still experiencing problems, there are a few things you can do to try and fix the issue. Here are eight ways to troubleshoot your Jeep key fob issue:

Make sure all of the buttons on the key fob are fully functional. Make sure that they’re pressed in properly and aren’t stuck or loosely connected.
Check for any broken or damaged wires inside the key fob. These can become disconnected over time, causing issues with button operation.
Try resetting the key fob by pressing all of the buttons at once for 10 seconds or so. This sometimes clears up intermittent issues with keys not working correctly or batteries not holding a charge

When to replace your Jeep key fob battery

Whether your Jeep key fob is not working or just isn’t holding a charge like it used to, there are usually some easy fixes you can try before you have to replace the battery. Here are 8 ways to fix your Jeep key fob and get it back up and running:

Check if your vehicle’s ignition is turned off

If your Jeep key fob doesn’t work, chances are that the car’s engine won’t start, too. Make sure all of the car’s electrical systems are off by pressing the button on the door handle or turning on the Ignition Warning Light with a key.

Check for obstructions in the fuel line

It could be that something got lodged in between your Jeep key fob and its battery, causing it not to work. If you’re having trouble igniting your car but can turn it on with another remote, check for any obstructions in the fuel line near where either of those devices might be plugged into the car (or even underhood). Remove any debris or particles found and try again.

Reset your Jeep key fob battery

If none of these tips help troubleshoot your Jeep key fob issue, then it may be time to reset its battery. Do this by holding down both buttons on top of the device until two green lights light up simultaneously – after which you should release both buttons and hold them down again until two red lights light up together. Keep repeating these steps until your jeep starts responding normally to both remotes – typically this will reset everything, including its battery power.

How to program a new Jeep key fob

Take the old key fob to a locksmith

Replace your Jeep key fob battery:

Remove the security screws on the back of the key fob.
Lift off the top panel of the key fob housing. Behind it is a small black circuit board with two electrical connectors. One connector has a yellow wire coming out of it and one has a blue wire coming out of it. Remove these wires from their connectors and set them aside (you’ll need them later).
Carefully pry up one end of the plastic bezel that covers the screen on the key fob housing. The screen should pop off easily once you’ve freed it up.
Inspected inside, you’ll see that there are three little rubber buttons in a line. The middle one is for the lock, the right one is for the unlock and the left one is for Start. You’ll also see a small white control unit on top of the key fob with four buttons on it: three little circles in a row and a crosshair.
The first step in programming your new Jeep key fob is to connect it to your computer. Use the included USB cable to connect it to your PC. Once it’s connected, click on “Start Automation” from the main window of KeySmart software.

Once you’ve filled out all the fields, click on “Next” and then on ” Activate.” This will activate your key fob with your Jeep’s registered system. You’ll also see a new entry in the “Activated Keys” window.
Now we need to program it to work with our car. To do this, Click on “Program Key Fobs.” On the next window, enter your VIN number into the field called “Vehicle Identification Number” and click on “Next.” You’ll now be prompted to select which of the four buttons is for locking/unlocking your car (the middle one). Once you’ve selected it, click on “OK” to close out the window.
Now we need to assign a code to your Jeep. To do this, Click on “Program Codes.” On the next window, enter your 5 digit personal code into the field called “Personal Code” and click on “Next.” You’ll now be prompted to select which of the four buttons is for starting your car (the left one). Once you’ve selected it, click on “OK” to close out the window.
That’s it! Your Jeep key fob is now programmed and ready to use. If you ever have problems with it, be sure to take it in for service.
