How to start an ATV without a key
Key Takeaways
-
- Function of the Key: Turning the ATV key simply completes an electrical circuit, allowing a spark to ignite the engine.
- Best Permanent Fix: Replacing the ignition switch is the recommended and simplest long-term solution, as new switches are often inexpensive and easy to install.
- Bypassing the Switch: The primary bypass method involves removing the ignition switch and connecting the two main wires leading to the engine to manually complete the circuit.
- Alternative Starting Methods: Other options for starting without a key include:
- Jump-Starting the Solenoid: Using a metal object (like an insulated screwdriver) to bridge the starter solenoid contacts.
- Jump-Starting the Battery: Using jumper cables to start the ATV if the key is lost and the battery is dead.
- Pull-Starting: Only available on ATVs equipped with a pull starter.
- High-Risk Method Warning: Jamming a screwdriver into the ignition may start the ATV by breaking the internal pins, but it will permanently damage the switch.
- Push-Starting: Generally, only ATVs with specific types of automatic transmissions can be safely push-started.
Buy a new ignition switch. If you’re camping and need immediate access to the ATV, getting a new ignition switch is a good alternative, especially if you can’t get a new key made. A new ignition switch is surprisingly inexpensive and should be easy to install.
Frequently Asked Questions
Here are five frequently asked questions based on the article about starting an ATV without a key:
Q: What is the easiest and safest way to start my ATV if I lose the key?
A: The easiest and safest long-term solution is to buy a new ignition switch. They are often inexpensive and replacing the entire switch assembly is simpler and less risky than attempting a temporary bypass.
Q: How does the key actually start the ATV?
A: The key is not a “magic trigger.” Turning the key in the ignition simply completes an electrical circuit. This allows the necessary spark to reach and ignite the engine.
Q: What is the basic method for bypassing the ignition switch in an emergency?
A: The basic method is to disassemble the switch or cut the two primary wires leading to it. You then connect these two wires together to complete the circuit, allowing the electric start to work. Remember to leave enough wire slack for later repair.
Q: Can I use a screwdriver to start the ATV?
A: Yes, but it is not recommended. While hammering a screwdriver into the ignition and turning it might break the internal pins and start the ATV, it will likely cause permanent damage to the ignition cylinder.
Q: Is jump-starting the solenoid a viable alternative?
A: Yes. You can bypass the starter relay/switch by carefully bridging the battery-side lug and the starter-side lug on the solenoid with an insulated screwdriver while the ignition is switched to the “on” position.
How to start an ATV without a key
To bypass, remove the ignition switch from the equation by disassembling the switch or cutting the two wires leading to it. However, be sure to leave enough slack on the wire for future use if you wish to replace the ignition switch later. After disassembling the switch, connect the two wires, and the electric start should work like always.
1. How does an ATV ignition switch work?
Replace the ignition switch. Your ATV key is not some magic trigger that makes everything in the engine work. Turning the key in the ignition completes a circuit that allows a spark to ignite the engine. Once that spark ignites the engine, assuming your engine is good, you are good to go, with or without a key.
2. How do you change the ignition switch?
Here are ways you can try. Replace the ignition switch. Your ATV key is not some magic trigger that makes everything in the engine work. Turning the key in the ignition completes a circuit that allows a spark to ignite the engine.
3. How do you replace an ATV solenoid?
Cut the wire that connects the solenoid to the battery. Locate the red wire exiting the battery. Connect the red wire from the battery to the wires you just cut. Start the ATV. Locate and remove the lamp/instrument cluster housing top part. It is typically connected via 3 Philips screws. Locate and remove the key switch assembly.
4. How do you remove ignition from an ATV?
First, loosen the ignition on your ATV. From there, you should see that your ignition is basically a cylinder that separates into two pieces. Second, you should be able to remove the bottom half of the cylinder that is connected to the cord leading to your ATV engine.

How do you start a car with a bad ignition switch?
Then locate the starter solenoid and connect the solenoid to the positive battery terminal. Then unplug the ignition switch wiring from the solenoid. Using a screwdriver, short the solenoid’s positive terminal to the post where the ignition switch connects. This will activate the solenoid, and the car should start up.

Can you start a car without a starter?
You can always jump-start your car, even if your starter is faulty. However, jumpstarting it is not a permanent solution to the problem. The moment the car begins to turn over, the starter will receive enough amps to start.
How do you bypass the ATV starter relay?
On some models, you can bridge the battery side lug and the starter side lug CAREFULLY with an INSULATED screwdriver with the key on. This effectively bypasses the relay and starter switch.
Can you pull-start an automatic ATV?
Generally, only ATVs with certain types of automatic transmission can be safely push-started. If you try to push-start an automatic ATV with the wrong transmission type, it will at best not start and, at worst, cause transmission damage.

How do you start a 4-wheeler with a dead battery?
Turn on the first ATV, or the one with a full battery, and let it run for about 3-5 minutes. After that, try and turn on the dead ATV with the cables still connected. Typically, this will do the trick, and your ATV will immediately start.
How do you start an ATV with a screwdriver?
Use A Screwdriver. Basically, you just hammer a screwdriver into the ignition and turn it on as if it were the key. The screwdriver will break the pins in the lock, allowing you to turn the ignition on. I don’t recommend this method because you could damage the ignition and still not get the quad to start.
What happens if the starter goes out?
When the starter drive gear is worn or not engaging properly, it often produces a grinding noise. This is similar to the one heard when you start your engine and then accidentally activate the ignition switch again. If the grinding symptom is ignored, it may also result in damage to the engine flywheel.

Final Thoughts
Multiple methods exist to start an ATV without a key, primarily by manually completing the electrical circuit controlled by the key switch.
For any non-emergency situation, the most reliable and safest approach is to purchase and install a replacement ignition switch or have a new key made.
Emergency methods such as bridging the starter relay or hotwiring the ignition should be performed carefully to avoid electrical damage.
