Compustar Bypass for Factory Transponder Remote Start

The Firstech Transponder Bypass Module, also known as the "Key-in-a-Box" Transponder Module, is designed for use on vehicles with a transponder-based anti-theft system. This adjustable transponder antenna loop is intended for vehicles that require precise tolerances on loop size and placement, such as BMWs, Mercedes, and Volkswagens. These vehicles often require the loop to be wound flat against the ignition cylinder, and any movement can cause the system to fail.

The v.2 adjustable loop offers a solution by allowing for a wide range of configurations with varying loop counts, diameters, and placements. This flexibility enables users to experiment and find the configuration that works best for their vehicle's tolerances, even when the exact answer is not known.

The adjustability of the loop size and the ability to mold it into different configurations are key features of this bypass module. Users will need to experiment with different loop sizes, coil counts, and placements to find the optimal setup for their specific vehicle.

This module is designed to work with a wide range of vehicles that may not have been compatible with other transponder bypass systems. It is a trial-and-error process, but the adjustability of the v.2 loop allows it to be used with many different vehicles.

The Firstech Transponder Bypass Module is a solution for installing remote start products in vehicles equipped with a radio frequency-based immobilizer system. These systems use a small chip, called a transponder, embedded in the ignition key to transmit a low-powered RF signal. Without this bypass module, the vehicle's security system would prevent the installation of a remote starter.

The module works by using one of the customer's spare keys. The module reads the signal from the key and transmits it to a ring installed around the key cylinder, tricking the car into thinking the factory key is in the ignition.

The product is compatible with various systems, as indicated by the tags: iDataLink (48), ADS- (31), ADS-THR- (31), ADS-HRN- (31), ads-thr (31), and ads-hrn (31).

In summary, the Firstech Transponder Bypass Module provides a flexible and adjustable solution for installing remote start products in vehicles with transponder-based anti-theft systems, particularly those with strict tolerances on loop size and placement. The module's ability to work with a wide range of vehicle makes and models makes it a valuable tool for installers.
