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 systems, engine on/off button functionality, 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 the need for complicated operations. If your key is larger than the module housing, remove the entire chip or PCB from the key and place it inside the module. Item Type: Immobilizer Bypass Module Material: ABS Power Supply Voltage: 12 V Working Temperature: -20 to 80 °C Application: Suitable for 12V vehicles When modifying a vehicle equipped with a chip in the remote or key, the original vehicle computer detects the chip data during startup. If the data is valid, the engine will start; otherwise, it will not. For installation, place the original vehicle remote or the chip from the original key into the module housing. The induction coil transmits the chip signal to the vehicle’s ignition lock cylinder. Installation requires a spare key to be placed inside the module. If the original key is too large, carefully remove the chip or PCB unit from the key housing. Some vehicles use RFID chip keys. To enable remote starting, a bypass module is required; otherwise, the engine will not start.
