Starting a Jeep Cherokee with a screwdriver is a skill sometimes needed in emergencies. For example, if your ignition switch fails or you lose your keys. While this method is not meant for daily use and should never be used for illegal purposes, it’s helpful for car owners and mechanics who need to move the vehicle in a pinch. This guide will explain how to do it safely, what tools you need, and the risks involved. You will also learn some practical advice that most beginners miss.
Understanding The Jeep Cherokee Ignition System
Before you try starting your Jeep Cherokee with a screwdriver, it’s important to know how the ignition system works. The ignition switch is responsible for sending power to the starter, fuel pump, and other systems. In older models (pre-2000), the system is simpler and easier to bypass. Newer models have more security features, such as transponder chips and immobilizers.
Here’s a quick comparison:
| Model Year | Ignition Complexity | Security Features |
|---|---|---|
| 1984-1999 | Simple | Basic key |
| 2000-2007 | Moderate | Transponder chip |
| 2008+ | Advanced | Immobilizer, chip key |
If your Jeep has a chip key or immobilizer, starting it with a screwdriver will not work unless you bypass the security. This article focuses on older models where this method is possible.
Tools You Need
To start a Jeep Cherokee with a screwdriver, prepare these tools:
- Flat-head screwdriver (8–10 inches is best)
- Phillips screwdriver (for dashboard panels)
- Pliers (optional, for wire handling)
- Flashlight (for visibility)
- Protective gloves
Never use makeshift tools, as they can damage your car.
Step-by-step Instructions
Follow these steps carefully. Mistakes can cause electrical damage or injury.
1. Access The Ignition Switch
First, locate the steering column. Remove the plastic cover using a Phillips screwdriver. You will see the ignition switch and wiring harness.
2. Identify The Wires
You need to find three wires:
- Battery wire (usually red)
- Ignition wire (often yellow or brown)
- Starter wire (typically green or blue)
If you are unsure, look for a wiring diagram for your specific year. Here’s a typical color code for 1995 models:
| Wire Color | Function |
|---|---|
| Red | Battery |
| Yellow | Ignition |
| Blue | Starter |
3. Start The Ignition
Put on gloves. Twist the battery and ignition wires together using the screwdriver or pliers. This will send power to the dash and fuel system.
4. Engage The Starter
Briefly touch the starter wire to the joined battery/ignition wires with the screwdriver. The engine should turn over. Remove the starter wire once the engine starts.
5. Secure Connections
Do not leave wires exposed. Use electrical tape to cover any bare wires to prevent short circuits.
Risks And Common Mistakes
Starting a car this way has risks:
- Electrical damage: Wrong wire connections can fry the fuse box.
- Fire hazard: Bare wires may spark.
- Steering lock: Most Cherokees have a steering lock that prevents turning the wheel. You cannot release it with a screwdriver alone.
- Legal issues: Only use this method on your own vehicle.
Most beginners forget about the steering lock. If the lock is engaged, you cannot drive the car even if it starts. Another common mistake is misidentifying wires. Always double-check colors and functions.
Practical Tips
- Always check the battery charge before trying.
- If you are not sure about the wiring, download a manual for your Cherokee’s year.
- Keep a fire extinguisher handy.
- Practice on a non-running vehicle to build confidence.
Here’s a quick comparison of screwdriver starting vs. key starting:
| Method | Safety | Ease | Damage Risk |
|---|---|---|---|
| Key | Very Safe | Easy | None |
| Screwdriver | Risky | Moderate | High |
When Should You Use This Method?
This technique is best for emergencies like:
- Lost keys in remote areas
- Faulty ignition switch
- Moving a project vehicle
Never use it for regular driving. It’s a last-resort option.

Frequently Asked Questions
What If My Jeep Cherokee Has A Chip Key?
If your Cherokee uses a transponder chip, starting it with a screwdriver will not work. The engine may turn over but will not start. You need to bypass the security system, which is complex and not recommended for beginners.
Can I Damage My Vehicle By Using A Screwdriver?
Yes, connecting the wrong wires can cause electrical damage or start a fire. Always use caution, wear gloves, and work slowly. If unsure, consult a mechanic.
Will This Method Unlock The Steering Wheel?
No. The steering lock will stay engaged unless you remove it manually. Even if the engine starts, you cannot steer without unlocking this mechanism.
Is It Legal To Start My Own Jeep This Way?
It is legal if you own the vehicle. However, doing this on someone else’s car without permission is illegal. Always carry proof of ownership if you are stopped by law enforcement.
What Should I Do After Starting The Car?
Drive only if necessary. Replace the ignition switch as soon as possible. Cover exposed wires with tape and avoid leaving your vehicle unattended.
Starting a Jeep Cherokee with a screwdriver is a useful skill in emergencies, but it comes with risks. Always use proper tools, double-check your wiring, and understand your vehicle’s security features. If you are not confident, call a professional. Being prepared and knowing what to expect can save you time and trouble when faced with ignition problems.
