To start a Jeep Cherokee using the emergency key, especially when the key fob battery is dead, follow these straightforward steps. This guide is aimed at Jeep Cherokee owners who may find themselves in a situation where their key fob is not functioning.

Understanding the Emergency Key

The emergency key is a mechanical key hidden within your key fob. It allows you to unlock the vehicle when the electronic functions of the fob fail. Here's how to utilize it effectively.

Steps to Start Your Jeep Cherokee

1. Remove the Emergency Key

Locate the button on your key fob that releases the emergency key. Pull it out carefully.

2. Unlock the Door

Use the emergency key to unlock the driver's door. Insert the key into the lock and turn it counterclockwise.

3. Enter the Vehicle

Once inside, be prepared for the alarm to sound due to unauthorized entry.

4. Stop the Alarm

To stop the alarm, you need to start the vehicle.

5. Starting the Engine

- Press down on the brake pedal.

- Take your key fob and press its top against the START/STOP button on the dashboard.

- The vehicle should start, and this will also silence the alarm.

This method works because even if the fob's battery is dead, it can still communicate with the vehicle's ignition system when pressed against it due to its passive RFID chip technology.

Important Notes

  • If you find that this method does not work, ensure that you are pressing firmly against the start button with the correct side of the fob (the side opposite to where you removed the emergency key).
  • It’s advisable to replace your key fob battery as soon as possible after using this method to avoid future inconveniences.
