Assessing the situation

Before attempting to bypass the ignition switch, it is crucial to understand the reason behind it. If your ignition key is damaged, lost, or the ATV ignition switch is faulty, bypassing it may become necessary.

However, if there are other underlying issues, it is advisable to address them properly rather than bypassing the ignition system altogether.

Hot wiring

To begin, locate the wiring harness and identify the two wires connected to the ignition switch. In most cases, the red wire carries the electrical power, while the remaining wires control other electrical components.

Strip the red wire and connect it to a hot wire, such as the positive terminal of the battery, using a metal connector or electrical connector.

This bypasses the ignition switch by using two wires and allows the ATV to start when the electrical circuit is completed.

Wiring the starter

Locate the wire connecting the starter to the ignition switch. Strip the wire and connect it to a power source, such as the positive terminal of the battery. Be sure to use appropriate electrical or metal connectors to ensure a secure and reliable connection.

Using a relay

Begin by accessing the ignition switch connector. The first wire you should identify is the one that carries electrical power (usually the red wire) from the ignition switch to the starter switch. Connect this wire to the input terminal of the relay.

Then, connect the output terminal of the relay to the wire that leads to the starter motor.

Finally, connect the relay’s control terminal to a low-amp switch, such as a toggle switch or a push-button switch. When the switch is activated, it triggers the relay, completing the circuit and activating the starter motor.

Installing a toggle switch

Locate the wire connected to the switch that controls the electrical power. Cut this wire and connect the ends to a toggle switch, ensuring proper insulation and using metal connectors or electrical connectors.

Utilizing a push-button start

Begin by locating the wire connected to the key switch that activates the starter motor. Cut this wire and connect it to a push-button switch using metal or electrical connectors. When the switch is pressed, it completes the circuit and activates the starter motor, bypassing the ignition switch.

Installing a remote starter

This method involves accessing the wiring harness and identifying the wire that connects the key switch to the starter motor.

Connect this wire to a remote starter module, following the manufacturer’s instructions carefully.

CDI connector

Modifying Capacitor Discharge Ignition connector can serve as an alternative method to bypass the switch. By accessing the CDI unit, you can identify the ignition wire and disconnect it from the connector. Proceed with caution, as improper modifications can lead to damage or malfunction of the CDI system.

Plug connecting

Carefully examine the plug connections and ensure proper insulation and secure connections to prevent any electrical hazards. This method may require advanced knowledge of electrical systems and should only be attempted by individuals with expertise in ATV mechanics.

Safety precautions

Disconnect the ATV’s battery before attempting any modifications and ensure proper insulation of wires. Avoid haphazard wiring and use appropriate connectors to maintain a reliable and secure electrical connection.

Legal implications

Tampering with the ignition system may be illegal in some jurisdictions. It is important to consult local laws and regulations to ensure compliance. Engaging in unauthorized modifications can result in legal consequences.

Consequences of improper bypassing

It may compromise the safety and security of your ATV, increase the risk of accidents, and void any warranties.

Alternative methods

In certain cases, alternative methods can be used to bypass the ignition switch on an ATV:

Replace the ignition switch: If you face faulty ignition switch, replacing it with a new ignition switch can restore the proper functioning of the ATV’s ignition system. Refer to the manufacturer’s guidelines or consult a professional to help you to replace the ignition switch.

Using a pull mechanism: Some ATVs may have a pull-start mechanism as a backup option. Locate the mechanism, typically installed near the hood in front of the ATV, and follow the manufacturer’s instructions to start the ATV using this method.

Modifying the wiring harness: For advanced users with electrical expertise, modifying the harness for wiring can be an option. However, extreme caution must be exercised to avoid damaging the electrical system or compromising safety.

Connecting the kill wires: The kill switch wire, usually a green wire, is responsible for shutting off the engine.

By connecting kill switch wire to the ground wire or a switch, the ATV’s engine can be turned off, effectively bypassing the ignition switch.

Ignition switch connector: Locate the key switch connector, which is often found near the handlebars or under the front hood. Disconnecting the wires from the connector and connecting the appropriate wires will help to bypass the ignition switch.

Connecting the key switch assembly: In some ATVs, the key switch assembly contains electrical components that can be bypassed. Identify the wires coming from the key switch set and locate the wire connected to the switch. Cut this wire and connect it to a jumper wire.

If you have any questions left:

How do you bypass the ignition switch on an ATV?

How do you bypass the ignition switch on an ATV? To bypass the key switch on an ATV, there are several methods that can be employed. Some common approaches include hot wiring the ignition system, directly wiring the starter, using a relay, installing a toggle switch, utilizing a push-button start, or installing a remote starter.

Is there a way to bypass an ignition switch

Is there a way how to bypass ignition switch on ATV? Yes, there are ways to bypass a key switch, depending on the specific circumstances and the ATV model.

Methods such as hotwiring the ignition system, directly wiring the starter, or using alternative switches like toggle switches or push-button starts can help bypass the key switch.

Can you pull start an ATV without a key?

Yes. Some ATVs are equipped with a pull-start mechanism, usually located near the front hood. By using that mechanism, which involves pulling a cord or rope connected to the ATV’s internal combustion engine, you can start the ATV without relying on the key switch or a key.


Bypassing the switch on an ATV can be a temporary solution in specific circumstances. But the easiest solution to the problem is to replace the ignition switch.

However, it is crucial to approach such modifications with caution, considering the associated risks and legal implications. Prioritize safety, consult professionals, and adhere to manufacturer guidelines to ensure proper installation and maintenance of your ATV.
