Compustar Firstech FT-DC3-LC Remote Start Module FTDC3LC DC2-S Replacenemt DC3S 7200S Bypass Module for High and Low-Current Draw Vehicles.

The Compustar Firstech FT-DC3-LC is a bypass module designed to work with your vehicle’s factory security system when installing a remote start. It replaces older DC2-S and DC3S models and handles both high and low-current draw vehicles, making it compatible with a wider range of cars and trucks than standard bypass modules.

This module communicates directly with your vehicle’s data bus to safely bypass the factory immobilizer system during remote start sequences. Without a bypass module like this, your remote starter would trigger the factory alarm or prevent the engine from starting. The DC3-LC handles the handshake between your aftermarket remote start system and your vehicle’s computer, ensuring smooth operation every time you start your car from a distance.

Who Is This For?

This module is for vehicle owners installing or upgrading a Compustar remote start system in cars with factory security or immobilizer systems. It’s particularly useful if you have a vehicle with higher electrical demands or if previous bypass modules haven’t worked reliably. Professional installers will appreciate the compatibility with both the 7200S platform and legacy systems, making it a versatile solution for shops handling diverse vehicle types. If your current DC2-S or DC3S module is failing or you’re experiencing intermittent remote start issues, this replacement can restore full functionality.

Bottom Line

The FT-DC3-LC solves a specific technical problem: it lets your remote starter work with your factory security system without false alarms or start failures. It’s not a standalone remote start system but rather the critical interface component that makes remote starting possible on modern vehicles. If you’re upgrading an existing Compustar system or replacing a failed bypass module, this delivers reliable performance across high and low-current applications.

This module communicates directly with your vehicle’s data bus to safely bypass the immobilizer system during remote start sequences. Without a bypass module like this, your factory security would prevent the engine from starting remotely. The FT-DC3-LC uses vehicle-specific firmware that gets flashed during installation, ensuring proper integration with your make and model’s security protocols.

Who Is This For?

This module is for vehicle owners who want to add remote start capability to cars with factory security systems. It’s particularly useful if you have a vehicle with higher electrical demands or complex security features that standard bypass modules can’t handle. Professional installers will appreciate the compatibility with Compustar’s 7200S and other remote start systems. If you’re upgrading from an older DC2-S or DC3S module, this is your direct replacement with improved current handling.

Bottom Line

The FT-DC3-LC solves a specific technical problem: it lets you add remote start without triggering your factory alarm or immobilizer. The dual current capability means it works where other bypass modules fail, especially in vehicles with demanding electrical systems. This is a professional-grade component that requires proper installation and programming, but it delivers reliable performance once configured correctly for your vehicle.
