Think of this as your go-to reference—whether you’re a new Jeep owner or just brushing up on the basics.

Understanding Your Jeep Cherokee’s Ignition System

Before you even touch the key, it’s important to understand what kind of ignition system your Jeep Cherokee uses. This determines how you’ll start the vehicle and what tools you’ll need. Let’s break it down by model year and technology.

Older Models (1997–2013): Traditional Key Ignition

If your Jeep Cherokee was made between 1997 and 2013, chances are it uses a traditional key ignition system. This means you’ll insert a metal key into a physical ignition cylinder, usually located on the right side of the steering column. These models don’t have push-button start—instead, you turn the key to start the engine, just like in older cars.

The ignition cylinder has several positions:
– **Off:** The key is removed or turned fully counterclockwise. No power to the vehicle.
– **Accessory (ACC):** Turn the key one click clockwise. This powers accessories like the radio and power windows, but not the engine.
– **On (Run):** Turn the key another click. The dashboard lights up, and the engine is ready to start.
– **Start:** Turn the key fully clockwise (you may need to hold it here for a second). The engine cranks and starts. Release the key, and it springs back to the “On” position.

It’s important to note that you should never force the key. If it doesn’t turn easily, double-check that the steering wheel isn’t locked (we’ll cover that later). Also, always make sure the vehicle is in Park (for automatics) or Neutral (for manuals) before starting.

Newer Models (2014–Present): Key Fob with Push-Button Start

Starting with the 2014 redesign, Jeep introduced a more modern ignition system. Most newer Cherokee models use a key fob—a small remote with buttons—and a push-button start instead of a traditional key. However, even these models still have a physical key hidden inside the fob for emergency use.

Here’s how it works:
– The key fob communicates with the vehicle via radio frequency.
– As long as the fob is inside the vehicle (usually in your pocket or purse), you can start the engine by pressing the Start/Stop button.
– You must press the brake pedal while pressing the button to start the engine.
– To turn off the engine, press the button again with the brake pressed.

But what if your fob battery dies? That’s where the physical key comes in. Most fobs have a small release button or slider that lets you pop out a metal key blade. This key can be used to unlock the driver’s door manually. Once inside, you can still start the vehicle using the fob—even if the battery is dead—by placing it in a special “backup” slot near the steering column or cup holder (we’ll explain this in detail later).

Hybrid Systems: Key Fob with Backup Key Slot

Some 2014–2018 models include both a key fob and a physical ignition slot as a backup. This hybrid system gives you flexibility. You can use the fob for everyday driving, but if the battery dies or the fob is lost, you can still insert the physical key into the ignition cylinder to start the vehicle.

This design is especially helpful in emergencies. For example, if you accidentally lock your fob inside the car, you can use the physical key to unlock the door and retrieve it. Or, if the fob stops working, you’re not stranded—just insert the key and turn it like in an older model.

Step-by-Step: How to Turn on Jeep Cherokee with Key

Now that you know what kind of system you’re dealing with, let’s walk through the actual process of starting your Jeep Cherokee. We’ll cover both traditional key ignition and key fob methods, so you can follow along no matter which model you have.

Starting a Jeep Cherokee with a Physical Key (1997–2013)

If your Cherokee uses a traditional key, here’s how to start it:

1. **Ensure the vehicle is in Park (or Neutral for manuals):** This is critical for safety. If the vehicle is in Drive or Reverse, it could lurch forward when you start the engine.

2. **Insert the key into the ignition cylinder:** The cylinder is usually on the right side of the steering wheel. Push the key in gently until it stops.

3. **Turn the key to the “On” position:** Rotate the key one click clockwise. You’ll hear a few clicks, and the dashboard lights will illuminate. This powers up the vehicle’s electronics.

4. **Wait for the dashboard lights to stabilize:** Some lights (like the check engine light) may flash briefly. That’s normal. Wait a second or two for everything to settle.

5. **Turn the key to “Start”:** Rotate the key fully clockwise. You’ll hear the engine crank. Hold it there until the engine starts—usually 1–3 seconds.

6. **Release the key:** Once the engine is running, let go. The key will spring back to the “On” position automatically.

7. **Check for warning lights:** If any warning lights stay on (like oil pressure or battery), turn off the engine and investigate.

Pro tip: If the key won’t turn, the steering wheel might be locked. Gently wiggle the steering wheel left and right while turning the key. This often releases the lock.

Starting a Jeep Cherokee with a Key Fob (2014–Present)

For newer models with push-button start, follow these steps:

1. **Make sure the key fob is inside the vehicle:** The fob must be in the cabin—on your person, in a cup holder, or in the glove box. The vehicle won’t start if it can’t detect the fob.

2. **Press the brake pedal:** This is required to start the engine. If you don’t press the brake, the button will only cycle between “Off” and “Accessory” modes.

3. **Press the Start/Stop button:** Located near the gear shifter or on the dashboard, press the button firmly while holding the brake.

4. **Listen for the engine to start:** The engine should crank and fire up within a few seconds. If it doesn’t, check the fob battery or try the backup method.

5. **Release the button and brake:** Once the engine is running, you can let go.

If the fob battery is dead, don’t panic. Most models have a backup method:

– **Locate the backup key slot:** On many 2014–2018 Cherokees, there’s a small slot near the cup holder or center console labeled “Fob Backup” or “Key Slot.”
– **Insert the fob into the slot:** Push the fob in until it clicks. This allows the vehicle to detect it even with a dead battery.
– **Press the Start/Stop button with the brake:** The engine should now start.

For models without a backup slot, you may need to use the physical key to unlock the door, then place the fob as close as possible to the Start/Stop button (some owners tape it to the button) to boost signal strength.

Using the Physical Key as a Backup (All Models)

Even if your Jeep has a key fob, it’s smart to know how to use the physical key in emergencies. Here’s how:

1. **Unlock the door manually:** Use the metal key blade (hidden in the fob) to unlock the driver’s door. Insert it into the keyhole and turn.

2. **Enter the vehicle:** Once inside, locate the ignition method (key cylinder or push-button).

3. **Start the engine:** Follow the steps above based on your model.

This backup method is especially useful if:
– The fob battery dies.
– The fob is lost or damaged.
– The vehicle’s electronics malfunction.

Always keep your physical key accessible—don’t leave it locked inside the car!

Troubleshooting Common Issues

Even with the right steps, things can go wrong. Here are some common problems and how to fix them.

Key Won’t Turn in the Ignition

If your key won’t turn, it’s usually due to one of these reasons:

– **Steering wheel lock:** The steering wheel may be locked in place. Gently wiggle the wheel left and right while turning the key. This often releases the lock.
– **Ignition cylinder wear:** Over time, the cylinder can wear out. If the key turns but doesn’t start the engine, the cylinder may need replacement.
– **Dirt or debris:** Dust or grime can build up in the cylinder. Use a can of compressed air or a graphite-based lubricant (not oil) to clean it.

Push-Button Start Not Working

If your push-button start isn’t responding:

– **Check the fob battery:** Replace it if it’s weak. Most fobs use a CR2032 battery.
– **Ensure the fob is inside:** The vehicle won’t start if it can’t detect the fob.
– **Press the brake:** You must press the brake pedal to start the engine.
– **Try the backup slot:** Insert the fob into the backup slot if available.
– **Check for warning messages:** The dashboard may display a message like “Key Not Detected” or “Service Keyless Entry.”

Engine Cranks But Won’t Start

If the engine turns over but doesn’t fire:

– **Check the fuel level:** You might be out of gas.
– **Listen for the fuel pump:** When you turn the key to “On,” you should hear a brief hum from the fuel pump. If not, there may be an electrical issue.
– **Inspect the battery:** A weak battery can cause slow cranking. Jump-start the vehicle if needed.
– **Look for warning lights:** A check engine light could indicate a sensor or fuel system problem.

Key Fob Not Detected

If the vehicle says “Key Not Detected”:

– **Replace the fob battery:** This is the most common fix.
– **Move closer to the vehicle:** Stand right next to the door or inside the cabin.
– **Use the backup method:** Insert the fob into the backup slot or place it near the Start/Stop button.
– **Reset the fob:** Some models allow you to reset the fob by pressing buttons in a specific sequence (check your owner’s manual).

Safety Tips and Best Practices

Starting your Jeep Cherokee safely is just as important as knowing how to do it. Follow these tips to avoid accidents and keep your vehicle in good condition.

Always Check the Gear Selector

Before turning the key or pressing the Start button, make sure the vehicle is in Park (for automatics) or Neutral (for manuals). Starting in Drive or Reverse can cause the vehicle to lurch forward, leading to injury or damage.

Use the Parking Brake on Hills

If you’re parked on a slope, always engage the parking brake before turning off the engine. This prevents the vehicle from rolling, even if it’s in Park.

Keep Your Keys Secure

Avoid leaving your keys in the ignition or on the dashboard. Not only is this a security risk, but it can also drain the battery or interfere with the vehicle’s electronics.

Maintain Your Key and Fob

– **Clean the key regularly:** Wipe it with a dry cloth to remove dirt and moisture.
– **Replace the fob battery:** Most last 1–2 years. Keep a spare CR2032 battery handy.
– **Avoid dropping the fob:** Impact can damage internal components.

Know Your Emergency Procedures

– **Jump-starting:** If the battery is dead, know how to jump-start your Jeep using jumper cables and another vehicle.
– **Towing:** If the vehicle won’t start and needs to be towed, ensure it’s in Neutral and the parking brake is off.
