What Causes The Start Push Button Not To Work In Jeep Cherokee? How To Fix?
The push-button start system in your Jeep Cherokee offers convenience, but it can be frustrating when it doesn’t work. Understanding the common causes and how to fix them can save you time and stress. Here’s a detailed look at the possible issues and solutions.
1# Brake Pedal Issue
The push-button start system in your Jeep Cherokee requires you to press the brake pedal fully before the engine will start. The brake pedal sensor detects when the pedal is pressed.
If you don’t press the pedal hard enough, the sensor won’t recognize it, and the car won’t start. This issue can be due to a misaligned sensor, a malfunctioning brake pedal switch, or insufficient pressure applied to the pedal.
How To Fix:
Ensure you press the brake pedal firmly and fully. Sometimes a simple increase in pressure can solve the issue.
If pressing harder doesn’t help, the brake pedal sensor or switch might be faulty.
Inspect the sensor for any misalignment or damage. Refer to your vehicle’s manual for the sensor location.
If you’re not comfortable inspecting or replacing the sensor yourself, visit a mechanic to have it checked and, if necessary, replaced.
2# Weak Key Fob Signal
The key fob communicates with your vehicle via radio signals. If the signal is weak due to interference from other electronic devices, physical barriers, or even low battery power, the vehicle might not receive the signal correctly, preventing the push-button start system from working.
How To Fix:
Here is how you can fix this.
- Bring the key fob closer to the vehicle and try again.
- Remove any potential sources of electronic interference, such as other electronic devices.
- Replace the key fob battery if it’s weak. A fresh battery can sometimes strengthen the signal.
- If the problem persists, you might need to reprogram the key fob. Consult your vehicle’s manual or visit a dealership for reprogramming.
3# Dead Key Fob Battery
The key fob requires a working battery to send signals to the car. If the battery is dead, the fob can’t communicate with the car’s system, preventing the push-button start from working.
How To Fix:
Replace the key fob battery. You can usually do this yourself:
- Open the key fob casing. This often involves using a small screwdriver to pry it open.
- Remove the old battery and replace it with a new one of the same type.
- Reassemble the key fob and test it.
- Refer to your vehicle’s manual for detailed instructions specific to your key fob model.
4# Faulty Key Fob
The key fob can become damaged due to physical impact, water exposure, or electronic malfunction, making it unable to communicate with the vehicle’s system.
How To Fix:
Check out the below steps to fix the issue.
- Step 1: Test the key fob by using a spare key fob, if you have one. If the spare works, the original key fob is likely faulty.
- Step 2: Replace the faulty key fob. You can purchase a new one from a dealership or authorized seller.
- Step 3: The new key fob will need to be programmed to your vehicle. This typically requires a visit to the dealership or a qualified locksmith.
5# Ignition System Issue
The ignition system includes several components, such as the ignition switch, that can malfunction.
Issues within the ignition system can prevent the engine from starting, even if the push-button start system appears to be functioning correctly.
How To Fix:
Have a professional mechanic diagnose the ignition system to identify the specific problem. Common issues include a faulty ignition switch, worn-out ignition cylinder, or problems with the starter motor.
The mechanic will repair or replace the faulty components as needed. This often involves detailed electrical work and should be handled by a professional.
6# Faulty Wiring Harnesses
The push-button start system relies on a network of wiring harnesses to transmit signals. If these wires are damaged, disconnected, or corroded, the system can’t function properly.
How To Fix:
The fixing steps are below.
Step 1: Inspect the wiring harnesses for visible damage, disconnections, or corrosion.
This requires locating the specific harnesses related to the start system, usually found under the dashboard or near the engine bay.
Step 2: Repair or replace any damaged wires. Use electrical tape or wire connectors for minor repairs.
Step 3: For significant damage or if you’re not comfortable working with vehicle wiring, have a professional mechanic handle the repairs.
7# A Blown Fuse
The electrical system in your Jeep Cherokee includes fuses that protect various circuits.
A blown fuse in the start system circuit can prevent the push-button start from working.
How To Fix:
Check out the below steps to fix the problem.
- Locate the fuse box in your vehicle. Refer to the owner’s manual for its exact location.
- Identify the fuse related to the push-button start system. The manual will have a diagram indicating each fuse’s function.
- Check if the fuse is blown. A blown fuse typically has a broken wire inside or appears discolored.
- Replace the blown fuse with one of the same amperage rating. Using the wrong amperage can cause electrical problems.
- If fuses continue to blow, have a mechanic inspect the electrical system for underlying issues.
Is There A Way To Manually Start My Jeep Cherokee If The Push-Button Start Isn’t Working?
Yes, Jeep Cherokees typically have a backup method to start the vehicle if the push-button start system isn’t working. You can use the traditional key to start the engine manually. Here’s how:
- Locate the key slot or ignition switch near the steering column or dashboard.
- Insert the key into the slot or ignition switch and turn it clockwise to start the engine.
- If the key slot or ignition switch is covered, you may need to remove the cover to access it.
- Once the engine starts, you can remove the key from the slot or ignition switch.
Using the manual start method can help you bypass the push-button start system temporarily until you can address the underlying issue causing the failure.
If the manual start method doesn’t work, or if you’re unsure about the process, it’s best to consult your vehicle’s manual or contact a professional mechanic for assistance.
