Types Of Jeep Cherokee Keys
Not all Jeep Cherokees use the same type of key. Understanding what kind of key you have is important before you start.
Traditional Metal Key
Older Jeep Cherokees (before 2014) usually come with a metal ignition key. This is a classic key that you insert and turn.
Key Fob With Integrated Key
Newer Cherokees (2014 and after) often use a key fob. Some fobs have a built-in metal key for manual starting. These vehicles may also have a push-button start, but the key can still be used as a backup.
Smart Key (proximity Key)
The latest models may use a smart key (also called a proximity key). These keys let you start the car with a button, but there is always a hidden metal key for emergencies.
Here’s a quick comparison:
| Key Type | Models/Years | Main Feature | Backup Option |
|---|---|---|---|
| Metal Key | Pre-2014 | Physical ignition switch | None |
| Key Fob with Key | 2014–present | Remote entry + ignition | Integrated metal key |
| Smart Key | 2020–present | Push-button start | Hidden emergency key |
How To Start Jeep Cherokee With Key: Step-by-step
The process depends on your model year and key type. Here’s how to start both older and newer Cherokees with a key.
For Older Jeep Cherokee (traditional Metal Key)
1. Unlock The Door
Insert the metal key into the driver’s door lock. Turn it to unlock.
2. Get In And Adjust
Sit in the driver’s seat. Adjust the seat and mirrors if needed.
3. Insert The Key
Find the ignition switch on the steering column. Insert the key fully.
4. Turn To “on”
Turn the key to the “On” position. Dash lights and gauges will come on. Wait a second for the fuel pump to prime.
5. Start The Engine
Turn the key further to the “Start” position. Hold until the engine starts (usually 1-2 seconds), then release. The key will return to “On” automatically.
6. Check For Warning Lights
Make sure all major warning lights turn off after a few seconds.
For Newer Jeep Cherokee (key Fob Or Smart Key)
1. Unlock With Fob
Press the unlock button on your key fob. If the fob battery is dead, use the metal key hidden inside to unlock the door.
2. Locate The Ignition Slot
Some models have a slot near the steering column or dash. If your fob battery is dead, insert the fob (or metal key) here.
3. Insert And Turn
If your Cherokee has a traditional ignition slot, insert the key or fob and turn to “On,” then “Start. ” For push-button models, press the brake and hold the fob close to the start button, then press the button.
4. Release After Start
Let go as soon as the engine catches. The car will keep running.
Here’s a quick reference:
| Model Year | How To Start | Special Note |
|---|---|---|
| Pre-2014 | Insert metal key, turn to start | Manual only |
| 2014–2019 | Insert key/fob, or use start button | Hidden key for emergencies |
| 2020+ | Use push-button, or emergency key start | Proximity needed, backup slot present |
What To Do If The Key Won’t Turn
Sometimes, the key gets stuck or won’t turn in the ignition. This problem is common and usually easy to fix.
Common Causes
- Steering wheel lock: If the wheel is turned hard left or right, the ignition may lock.
- Wrong key: Double-check that you’re using the correct Jeep key.
- Worn key or ignition: Older keys and switches can wear out.
- Dead battery: Some Cherokees need electrical power for the ignition to work.
Easy Fixes
1. Wiggle The Steering Wheel
Gently move the steering wheel left and right while turning the key.
2. Try Another Key
If you have a spare, see if it works better.
3. Check Battery
If nothing lights up on the dash, your battery may be dead.
4. Lubricate The Ignition
Use a tiny drop of graphite or silicone spray (never oil) in the ignition.
If none of these work, you may need a locksmith or Jeep dealer.
How To Start Jeep Cherokee With Key When Fob Battery Is Dead
This is a situation many owners face. Don’t worry—there’s a backup.
Slide the latch on the fob and pull out the metal key.
2. Unlock The Door
Use the metal key in the door lock.
3. Start With The Key
For models with a slot, insert and turn the metal key.
Hold the fob close to the start button, press the brake, and push the button with the fob itself. The car will read the chip inside the fob.
Many people don’t know about the hidden key or that the fob can still be used to start a push-button Jeep even when the battery is dead.
Tips For Starting In Extreme Weather
Cold or hot weather can make starting a Jeep Cherokee harder, especially for older models.
- In Cold Weather:
Wait for the dashboard’s “check engine” light to turn off before starting. If it’s very cold, turn the key to “On” for a few seconds to let the fuel pump prime.
- In Hot Weather:
Avoid holding the key too long in “Start”—if it doesn’t start in 5 seconds, wait and try again.
- Use Quality Fuel:
Bad or old gas can make starting harder.
- Battery Health:
Weak batteries often fail in extreme weather. Check and replace your battery every 3-5 years.

Common Mistakes Beginners Make
Starting with a key seems easy, but these mistakes are common:
- Using the wrong key or fob: Not every Jeep key works with every model.
- Forcing the key: If it doesn’t turn, forcing it can break the ignition.
- Ignoring warning lights: Always check the dashboard after starting.
- Not waiting for the fuel pump: In very cold weather, turning the key too fast may make starting harder.
- Not knowing about the hidden key: Many drivers don’t realize their fob has a backup metal key inside.
Knowing these can save you time and money, especially in emergencies.
Practical Tips For Smooth Starting
Here are a few extra tips from experienced Jeep owners:
- Keep a spare key: Store one at home or with a trusted friend.
- Test your battery: Every fall, check your Jeep’s battery health.
- Replace worn keys early: If your key looks bent or worn, get a new one before it fails.
- Learn to access your hidden key: Practice removing it at home so you’re not stressed during an emergency.
- Stay calm if it won’t start: Most problems are simple to fix—don’t panic.
When To Call For Help
If you’ve tried all the steps and your Jeep Cherokee still won’t start with the key, it’s time to get help. Common signs you need a professional:
- Key turns but engine won’t start (may be a battery, starter, or security problem)
- Key won’t turn at all (ignition cylinder may be broken)
- Key is lost or broken (call a locksmith or dealer)
For safety and to avoid damage, don’t try to force anything. Some newer models have advanced anti-theft systems that may require dealer service.
