Common Reasons Your Jeep Cherokee Starts Without a Key Fob
Several factors could contribute to your Jeep Cherokee starting without the key fob. These can range from simple issues like a dead key fob battery to more complex problems with the vehicle’s passive entry system. A common issue is simply having a weak key fob battery. If the battery is low, the signal might not reach the vehicle’s receiver, leading to difficulties in starting. Another common reason is a malfunctioning passive entry system. This system relies on sensors to detect the key fob’s presence, and if these sensors fail, it could cause issues with starting the vehicle.

Troubleshooting Key Fob Issues
If you suspect a problem with your key fob, start by checking the battery. Replace the battery with a fresh one and try starting the vehicle. If the problem persists, try holding the key fob close to the start button when starting the vehicle. This might bypass the passive entry system and allow the vehicle to recognize the key fob.
How Does Push-Button Start Work?
Push-button start systems utilize a key fob that transmits a radio frequency signal. The vehicle’s computer recognizes this signal, allowing the driver to start the engine by simply pressing a button. The key fob must be within a certain proximity of the vehicle for the system to work correctly.

What if the Key Fob Battery is Dead?
If your key fob battery is dead, many Jeep Cherokee models have a backup system. You can usually find a key slot hidden behind a panel near the steering column. Inserting the physical key into this slot can often disable the immobilizer and allow you to start the car. You might also be able to start the car by placing the dead key fob close to the start button, as mentioned earlier.
