How to Start Jeep Cherokee with Emergency Key

Stranded with a dead key fob? You can still start your Jeep Cherokee using the hidden emergency key. This guide walks you through locating the key, accessing the ignition slot, and safely starting your vehicle—even in a pinch.

This is a comprehensive guide about How To Start Jeep Cherokee With Emergency Key.

Key Takeaways

• Every Jeep Cherokee comes with an emergency key: It’s a physical key hidden inside the key fob, designed for backup use when the fob battery dies or malfunctions.
• The emergency key unlocks the driver’s door only: It won’t unlock the trunk or passenger doors, so plan accordingly if you need access to other areas.
• You must manually insert the key into the ignition slot: Unlike push-button start models, older Cherokees have a traditional key cylinder under the steering column.
• Newer models (2014+) require a different method: Push-button start Jeeps need the emergency key to access a hidden mechanical ignition slot near the steering column.
• Keep your emergency key accessible: Store it in a safe, dry place—like a wallet or glove box—so you’re never caught off guard.
• Replace the fob battery promptly: Once you’ve used the emergency key, replace the key fob battery to restore remote functionality.
• Practice the process before an emergency: Familiarize yourself with the steps now so you’re not fumbling in the dark or rain later.

How to Start Jeep Cherokee with Emergency Key

Imagine this: You’re running late for work, it’s pouring rain, and you press the unlock button on your Jeep Cherokee key fob—nothing happens. You try again. Still nothing. Panic starts to set in. Is your car broken? Did someone steal it? Not necessarily. More likely, your key fob battery has died—a common issue that leaves many Jeep owners stranded, especially in bad weather or at night.

The good news? Your Jeep Cherokee is equipped with a built-in safety net: the emergency key. Every modern Jeep Cherokee comes with a physical key hidden inside the key fob. This small, unassuming piece of metal is your lifeline when electronic systems fail. Whether your fob battery is dead, the signal is blocked, or the fob itself is damaged, the emergency key lets you unlock the door and start your vehicle manually. Knowing how to use it can save you time, stress, and potentially hundreds of dollars in towing fees.

In this comprehensive guide, we’ll walk you through everything you need to know about starting your Jeep Cherokee with the emergency key. From locating the hidden key to inserting it into the ignition and getting your engine running, we’ll cover all the steps—plus troubleshooting tips, maintenance advice, and real-life scenarios. Whether you drive a 2010 model or a 2023 Cherokee, this guide has you covered. Let’s get started.

Understanding Your Jeep Cherokee’s Emergency Key System

Before diving into the step-by-step process, it’s important to understand how the emergency key system works in your Jeep Cherokee. Unlike older vehicles that rely solely on physical keys, modern Jeeps use a combination of electronic key fobs and hidden mechanical backups. This dual system ensures you’re never completely locked out—even if technology fails.

What Is an Emergency Key?

The emergency key is a small, metal key that’s stored inside your key fob. It’s designed to work like a traditional car key, allowing you to manually unlock the driver’s door and, in most cases, start the engine. While the fob handles remote locking, unlocking, and push-button starting, the emergency key is your failsafe when the fob stops working.

Where Is the Emergency Key Located?

The emergency key is typically hidden in a small compartment on the side or back of the key fob. On most Jeep Cherokee models (2014 and newer), you’ll find a small release button or slider on the fob. Pressing or sliding it will pop out the emergency key. On older models (pre-2014), the key may be stored in a pull-out tray or behind a removable panel.

For example, on a 2018 Jeep Cherokee Limited, the emergency key is located on the side of the fob. Simply press the small button near the key ring loop, and the key will slide out. On a 2012 Cherokee, the key is stored in a pull-out drawer on the back of the fob—just slide it open with your fingernail or a small tool.

How Does It Work with the Ignition?

The way you start your Jeep Cherokee with the emergency key depends on the model year and ignition type. Older Cherokees (typically 2013 and earlier) have a traditional key ignition cylinder under the steering column. You insert the emergency key directly into this slot to start the engine.

Newer models (2014 and later) use a push-button start system. In these vehicles, the emergency key doesn’t go into a standard ignition slot. Instead, you use it to unlock the door, then locate a hidden mechanical key slot near the steering column (usually behind a small cover) to manually start the engine. This slot is often labeled “KEY” or has a key symbol.

Why Is This Feature Important?

The emergency key system is a critical backup for several reasons. First, key fob batteries die—often without warning. Second, electronic interference (like from cell phones or power lines) can block the fob’s signal. Third, fobs can be damaged by water, drops, or extreme temperatures. Having a physical key ensures you’re never completely locked out of your vehicle.

Additionally, the emergency key can be a lifesaver in emergencies. If you’re in a remote area with no cell service, or if your fob is lost or stolen, the emergency key lets you get back on the road. It’s also useful if you’ve accidentally locked your keys inside the car—just use the emergency key to unlock the door and retrieve them.

Step-by-Step: How to Start Your Jeep Cherokee with the Emergency Key

Now that you understand the basics, let’s walk through the actual process of starting your Jeep Cherokee using the emergency key. The steps vary slightly depending on your model year, so we’ll cover both older and newer Cherokees. Follow along carefully, and remember: practice makes perfect. Try this process in your driveway before you actually need it.

Step 1: Retrieve the Emergency Key from the Fob

The first step is to get the emergency key out of your key fob. Here’s how:

• For 2014 and newer models: Look for a small button or slider on the side of the fob. Press it firmly, and the emergency key will pop out. On some models, you may need to slide a small cover to the side first.
• For 2013 and older models: Check the back or side of the fob for a small drawer or panel. Use your fingernail, a paperclip, or a small flathead screwdriver to gently pry it open. The emergency key will be inside.

Pro tip: If you’re having trouble finding the release mechanism, consult your owner’s manual. It will show you exactly where the key is stored and how to access it. Keep the manual in your glove box for easy reference.

Step 2: Unlock the Driver’s Door

Once you have the emergency key, insert it into the keyhole on the driver’s side door. This keyhole is usually located near the door handle, often hidden behind a small cover. On some models, you may need to remove a plastic cap to reveal the keyhole.

Turn the key clockwise to unlock the door. You should hear a click, and the door should open. Note that the emergency key only unlocks the driver’s door—it won’t unlock the passenger doors, rear doors, or trunk. If you need access to other areas, you’ll have to use the manual locks inside the car.

Step 3: Locate the Ignition Slot (Older Models)

If you drive a Jeep Cherokee from 2013 or earlier, your vehicle likely has a traditional key ignition. Here’s what to do:

• Sit in the driver’s seat and look under the steering column.
• You’ll see a round ignition slot—this is where you insert the key.
• Insert the emergency key into the slot and turn it to the “ON” position (usually the second click).
• Wait for the dashboard lights to come on, then turn the key further to “START” to crank the engine.

Once the engine starts, you can remove the key. The vehicle will continue to run normally. Just remember to replace the fob battery as soon as possible so you can use the remote functions again.

Step 4: Access the Hidden Ignition Slot (Newer Models)

For 2014 and newer Jeep Cherokees with push-button start, the process is a bit different. These models don’t have a visible ignition slot. Instead, you need to find the hidden mechanical key slot. Here’s how:

• Sit in the driver’s seat and look near the steering column, usually on the left side.
• You’ll see a small plastic cover—often labeled “KEY” or marked with a key symbol.
• Use your fingernail or a small tool to gently pry off the cover.
• Inside, you’ll find a small keyhole—this is the emergency ignition slot.
• Insert the emergency key and turn it to the “ON” position.
• Wait for the dashboard to light up, then press the brake pedal and press the START button to crank the engine.

Note: On some newer models, you may need to hold the key in the slot while pressing the START button. The vehicle’s system reads the key’s chip to authenticate it, so it must remain inserted during startup.

Step 5: Start the Engine and Drive Safely

Once the engine is running, you can drive your Jeep Cherokee normally. However, keep in mind that some features—like remote start, keyless entry, and push-button start—won’t work until you replace the fob battery. Also, if you used the emergency key to start the car, the system may display a warning message on the dashboard. This is normal and will disappear once the fob is functional again.

Pro tip: After starting the car, drive to an auto parts store or dealership to replace the fob battery. Most fob batteries (typically CR2032) cost less than $5 and can be replaced in minutes. Some fobs have a simple screw-on back, while others require a small tool to pry open. Check your owner’s manual for instructions.

Troubleshooting Common Issues

Even with the right steps, you might run into problems when using the emergency key. Here are some common issues and how to fix them.

The Emergency Key Won’t Come Out of the Fob

If the key is stuck, don’t force it. Check if the release button is fully pressed or if the slider is aligned correctly. Sometimes dirt or debris can block the mechanism. Try cleaning the area with compressed air or a soft brush. If it’s still stuck, consult your dealer—forcing it could damage the fob.

The Key Doesn’t Turn in the Door Lock

If the key won’t turn, it might be due to a frozen lock (in cold weather) or a worn key. Try spraying a small amount of lock de-icer or WD-40 into the keyhole. Wait a few minutes, then try again. If the key is bent or damaged, you may need a replacement from your dealer.

The Engine Won’t Start Even with the Key in the Slot

If you’ve inserted the key correctly but the engine won’t start, check the following:

• Is the key fully inserted and turned to “ON”?
• Is the brake pedal pressed (required for push-button models)?
• Is the key fob battery completely dead? Some systems require a minimal charge to authenticate the key.
• Is the vehicle in Park or Neutral (for automatic transmissions)?

If none of these work, the issue might be with the ignition cylinder or the vehicle’s immobilizer system. In that case, contact a Jeep service center for assistance.

The Dashboard Shows a “Key Not Detected” Message

This message appears when the vehicle can’t detect the key fob. If you’re using the emergency key, it’s normal—just start the car as described. However, if you’ve replaced the fob battery and the message persists, the fob may need reprogramming. Visit your dealer or a locksmith with Jeep experience.

Maintenance Tips to Avoid Emergency Situations

The best way to handle an emergency is to prevent it. Here are some tips to keep your key fob and emergency key in top condition.

Replace the Fob Battery Regularly

Most key fob batteries last 2–3 years. Replace them before they die completely. Keep spare batteries in your glove box or emergency kit. When replacing, handle the battery carefully—avoid touching the contacts with your fingers, as oil can reduce lifespan.

Store the Emergency Key Safely

Don’t leave the emergency key in the fob all the time—it can wear out the release mechanism. Instead, store it in a small pouch in your wallet, glove box, or center console. Make sure it’s protected from moisture and extreme temperatures.

Test the System Periodically

Once a month, try removing the emergency key and using it to unlock the door. This ensures the mechanism works and helps you remember the process. It’s also a good idea to practice starting the car with the emergency key in a safe, dry environment.

Protect Your Fob from Damage

Avoid dropping your key fob or exposing it to water. If you’re going swimming or hiking, consider leaving the fob in a waterproof bag. Also, keep it away from strong magnetic fields (like speakers or microwaves), which can interfere with the signal.

When to Call a Professional

While the emergency key system is designed for DIY use, there are times when you should seek professional help.

• If the key is broken or lost: Your dealer can cut a new emergency key using your vehicle’s VIN. This usually costs $50–$100.
• If the ignition slot is damaged: A worn or broken ignition cylinder may need replacement by a mechanic.
• If the fob needs reprogramming: After replacing the battery, some fobs require a reset. Dealers and locksmiths can do this quickly.
• If you’re locked out and can’t access the key: In rare cases, the fob mechanism may fail completely. A locksmith with automotive experience can help.

Conclusion

Knowing how to start your Jeep Cherokee with an emergency key is a valuable skill that every owner should have. It’s not just about convenience—it’s about safety, preparedness, and peace of mind. Whether you’re caught in a storm, stranded in a parking lot, or dealing with a dead fob, the emergency key gives you a reliable way to get back on the road.

Remember, the key to success is preparation. Practice the process now, keep your fob battery fresh, and store your emergency key in a safe, accessible place. With these steps, you’ll never be truly locked out of your Jeep Cherokee again. Stay safe, stay prepared, and enjoy the freedom that comes with knowing you’re always in control.
