Installing a Viper remote start system on your Silverado can significantly enhance convenience, allowing you to start your truck remotely and enjoy a pre-cooled or pre-heated cabin. However, some Silverado models have factory anti-theft systems that can prevent aftermarket remote starts from functioning correctly. This guide addresses the common challenge of bypassing the factory disable to successfully install your Viper remote start. We'll explore the process, potential issues, and professional installation considerations.
Why Does My Silverado Have a Factory Disable for Remote Start?
Many modern vehicles, including Silverados, incorporate sophisticated anti-theft systems. These systems are designed to prevent unauthorized access and operation of the vehicle. A factory disable is a security measure that blocks aftermarket remote start systems from functioning unless properly bypassed. This prevents thieves from easily exploiting vulnerabilities introduced by an aftermarket remote start installation.
How to Bypass the Factory Disable on Your Silverado (General Overview)
Bypassing the factory disable requires specialized knowledge and tools. This is not a beginner's project. Improper installation can damage your vehicle's electrical system, void your warranty, or even compromise your vehicle's security. The specific bypass method depends heavily on the year and model of your Silverado. There is no single universal solution. You'll generally need:
- A Viper remote start system: The specific kit will depend on your Silverado's year and model.
- A wiring harness: This simplifies the installation process and helps avoid incorrect wiring.
- A bypass module: This module interfaces between the Viper system and your Silverado's factory security system. Different bypass modules are needed for different vehicle years and models. Popular options include the Fortin EVO-ALL and other brand-specific bypass modules.
- Detailed installation instructions: Your Viper kit should come with instructions, but supplemental guides and videos specifically for your Silverado year and model are highly recommended.
- Tools: A basic set of automotive tools including wire strippers, crimpers, and a multimeter will be necessary.
The process generally involves:
- Identifying the correct wires: This often requires consulting wiring diagrams specific to your Silverado's year and model. Incorrect wire connections can cause serious damage.
- Connecting the bypass module: This module intercepts and modifies signals to bypass the factory immobilizer.
- Connecting the Viper system: The Viper system is connected to the vehicle's electrical system according to the provided instructions.
- Programming the system: Once everything is connected, the system must be programmed to work correctly with your vehicle.
What if I Don't Want to Bypass the Factory Disable?
If you're uncomfortable bypassing the factory disable or lack the necessary expertise, the best course of action is to hire a professional installer. Many automotive electronics installers specialize in remote start installations and possess the knowledge and tools to handle the complexities of bypassing the factory disable safely and effectively.
What are the Risks of Incorrect Installation?
Improper installation carries significant risks, including:
- Damaged vehicle electronics: Incorrect wiring can short-circuit components, causing damage and potentially expensive repairs.
- Voiding your warranty: Unauthorized modifications to your vehicle's electrical system might void your warranty.
- Compromised security: A poorly installed remote start system could create security vulnerabilities, making your vehicle more susceptible to theft.
- System malfunction: An incorrectly installed system might not function correctly, rendering your investment useless.
Can I Find Installation Videos for My Specific Silverado Year and Model?
Yes! YouTube and other online platforms offer numerous installation videos. However, always verify the video's relevance to your specific Silverado's year and model. A video for a 2015 Silverado won't necessarily work for a 2023 model. Be cautious and cross-reference with your Viper installation manual.
How Much Does Professional Installation Cost?
The cost of professional installation varies depending on your location, the installer's experience, and the complexity of the installation. Expect to pay several hundred dollars. This cost should be weighed against the risks of attempting a DIY installation.
Conclusion
Installing a Viper remote start on your Silverado can be a rewarding upgrade, but it requires careful planning and execution. If you are not comfortable working with vehicle electronics, professional installation is strongly recommended to avoid damage and security risks. Always consult your Viper installation manual and seek additional guidance from reputable sources tailored to your specific Silverado model.
