Your Jeep Cherokee’s push button start may fail due to a weak key fob battery or an issue with the brake pedal sensor. Ensure the brake is firmly pressed and try using a spare key fob.
A non-starting Jeep Cherokee with a push button can be frustrating. Often, the issue boils down to the key fob battery being weak or dead, or the vehicle not recognizing that the brake pedal is being adequately depressed. Both of these issues are common and can usually be resolved quickly.
Ensure the key fob battery is fresh and properly seated. If you have a spare key fob, try using it to see if the problem persists. Additionally, make sure your foot is firmly on the brake pedal when attempting to start the vehicle. If the issue continues, it may be worth consulting a professional for a more thorough diagnosis.
Common Reasons For Push Button Failure
Owning a Jeep Cherokee brings joy and adventure, but sometimes, your push button start system might fail. Understanding the common reasons for push button failure can help you troubleshoot the problem and get back on the road quickly. Below are some typical issues that may cause your Jeep Cherokee not to start.
Brake Pedal Issue
One of the most frequent issues is the brake pedal. The push button start system requires you to press the brake pedal before starting. If the pedal is not engaged properly, the car won’t start. Ensure your foot is firmly on the brake pedal. Sometimes, dirt or debris can obstruct the pedal sensor. Cleaning the area around the pedal might resolve the issue.
Brake pedal sensors can also fail. If cleaning doesn’t work, the sensor may need replacement. A faulty sensor won’t send the correct signal to the system, preventing the car from starting.
Gear Position Problem
Another common issue is the gear position. The push button start system requires the car to be in “Park” or “Neutral.” If the gear lever is not in the correct position, the system won’t engage. Ensure the gear lever is fully in “Park” before attempting to start.
Sometimes, the gear position sensor might be faulty. This sensor tells the system the current gear of the car. If it fails, the system won’t recognize the correct gear, preventing the car from starting. Replacing the gear position sensor might be necessary.
| Common Issues | Potential Solutions |
|---|---|
| Brake Pedal Not Engaged | Ensure foot is firmly on the brake pedal |
| Dirt or Debris on Pedal Sensor | Clean area around brake pedal |
| Faulty Brake Pedal Sensor | Replace brake pedal sensor |
| Gear Not in “Park” | Ensure gear lever is fully in “Park” |
| Faulty Gear Position Sensor | Replace gear position sensor |

Electrical System Troubles
If your Jeep Cherokee won’t start with the push button, it might be due to electrical system troubles. These issues can disrupt the power flow, preventing your car from starting. Understanding the root cause helps in fixing the issue quickly.
Blown Fuse
A blown fuse can stop your Jeep Cherokee from starting. Fuses protect the electrical circuits by breaking the connection if there’s an overload. When a fuse blows, it cuts off the power supply to the ignition system. To check for a blown fuse:
- Open the fuse box located under the dashboard.
- Use the fuse diagram on the cover to locate the ignition fuse.
- Remove the fuse and inspect if the metal strip is broken.
If you find a blown fuse, replace it with a new one of the same rating. This simple fix can often get your Jeep starting again.
Faulty Relay
A faulty relay can also cause starting issues in your Jeep Cherokee. Relays are switches controlled by electrical signals. They help manage the flow of electricity to various components. If a relay fails, the push button start might not work. To diagnose a faulty relay:
- Locate the relay box, usually near the fuse box.
- Identify the starter relay using the diagram on the cover.
- Swap the suspected relay with a similar one from a working component.
If the car starts with the swapped relay, the original one is faulty and needs replacement.
Understanding these common electrical system troubles can help you identify and fix why your Jeep Cherokee won’t start with the push button. Always ensure your vehicle’s electrical components are in good condition to avoid unexpected starting issues.
Key Fob Malfunctions
Experiencing problems with your Jeep Cherokee’s push button start? The key fob might be the culprit. Key fob malfunctions can prevent your Jeep from starting, even if everything else appears to be in order. Let’s explore two common issues: weak key fob battery and defective key fob.
Weak Key Fob Battery
A weak key fob battery can be a common issue. If your key fob’s battery is low, it may not send the proper signals to your vehicle. This can prevent your Jeep Cherokee from starting with the push button.
Signs of a weak key fob battery include:
- Reduced range for remote functions
- Intermittent response
- Complete failure to unlock or start the vehicle
To resolve this, replace the battery in your key fob. Most key fobs use CR2032 lithium batteries, which are easily available. Here’s a quick guide:
- Locate the key fob seam and gently pry it open.
- Remove the old battery.
- Insert the new battery, ensuring the correct orientation.
- Snap the key fob back together.
Defective Key Fob
If replacing the battery does not solve the issue, your key fob might be defective. A defective key fob can result in your Jeep Cherokee not recognizing the key, hence not starting.
Common symptoms of a defective key fob include:
- Key fob not working even with a new battery
- Inconsistent performance
- Physical damage to the key fob
If you suspect your key fob is defective, try the following steps:
| Action | Description |
|---|---|
| Use a Spare Key Fob | Try starting your Jeep with a spare key fob. |
| Check for Physical Damage | Inspect the key fob for visible signs of damage. |
| Contact a Dealer | Visit a Jeep dealer for a professional assessment. |
Addressing these key fob issues can often restore the functionality of your push button start system.
Engine Starting Issues
Experiencing engine starting issues can be frustrating, especially with a push-button start system. If your Jeep Cherokee won’t start despite pushing the button, several factors could be at play. Let’s explore some common reasons behind this problem.
Failing Starter
A failing starter is a frequent culprit behind starting problems. The starter motor is responsible for cranking the engine. If it fails, your Jeep won’t start. Signs of a failing starter include:
- Clicking noise when pressing the start button
- Engine not turning over
- Intermittent starting issues
It’s essential to check the starter and its connections. Sometimes, the problem might be due to loose or corroded terminals.
Bad Crank Sensor
Another common issue is a bad crank sensor. This sensor sends signals to the engine’s computer, indicating the crankshaft position. If the sensor malfunctions, the engine may not start. Symptoms of a bad crank sensor include:
- Engine cranks but won’t start
- Intermittent stalling
- Check engine light is on
Replacing the crank sensor can resolve these issues. Ensure to get a proper diagnosis before replacing any components.
| Issue | Symptoms | Solution |
|---|---|---|
| Failing Starter | Clicking noise, engine not turning over | Check starter and connections |
| Bad Crank Sensor | Engine cranks but won’t start, intermittent stalling | Replace crank sensor |
Identifying and addressing these common issues can help get your Jeep Cherokee back on the road. Regular maintenance and timely repairs are key to avoiding starting problems.
Troubleshooting Steps
If your Jeep Cherokee won’t start with the push button, don’t worry. There are a few simple troubleshooting steps you can follow. These steps can help identify and resolve the issue quickly.
Check Brake Pedal
One common reason your Jeep Cherokee won’t start is the brake pedal. Ensure you are pressing firmly on the brake pedal while attempting to start the vehicle.
- Press the brake pedal hard.
- Check for any obstructions under the pedal.
- Verify that the brake lights turn on when pressed.
If the brake lights don’t turn on, there might be an issue with the brake switch. This switch must work properly for the push button start system to function.
Confirm Gear Position
Your Jeep Cherokee must be in the correct gear position to start. Ensure that the vehicle is in Park (P) or Neutral (N).
- Check the gear shift lever.
- Ensure it is securely in the P or N position.
- If in Neutral (N), try shifting to Park (P).
Sometimes, the gear shift may not fully engage. Shifting between gears and returning to Park (P) can help reset the system.
| Step | Action |
|---|---|
| Check Brake Pedal | Press firmly, check for obstructions, verify brake lights |
| Confirm Gear Position | Ensure in Park (P) or Neutral (N), shift between gears if needed |
