It is a bypass module designed to release the chip key, featuring a universal and safe design with stable performance. Bypasses the immobilizer chip on OEM keys or fobs to support remote start, car alarm, engine on/off button, and key duplication. This module is compatible with most chip key vehicles and is not intended for use with other immobilizer systems. Features a simple two-wire connection for easy and fast installation without complicated operations. If your key is larger than the module housing, remove the entire chip or PCB from the key. Item Type: Immobilizer Bypass Module Material: ABS Power Supply Voltage: 12 V Working Temperature: -20C to 80C Application: Suitable for 12V vehicles When modifying a vehicle equipped with a chip in the remote control, the original car computer detects the chip data in the key at startup. If the data is correct, the engine will start; otherwise, it will not. For installation, place the original car remote or the chip from the original key into the bypass module housing and transmit the chip signal to the ignition lock coil via the included induction coil. How to install the bypass module? (Note: A spare key is required to place inside the housing. If your original key is too large, open it to retrieve the chip unit.) Some vehicles use RFID chip keys. To enable remote start functionality, a bypass module is required; otherwise, the engine will not start.
