Installing keyless entry in a BMW will not affect the system. Below is relevant information about keyless entry installation: Introduction to Keyless Entry: The keyless entry system refers to an intelligent system that utilizes advanced RFID (Radio Frequency Identification) technology and identity coding recognition. It eliminates the need for traditional mechanical keys to unlock the car door or start the vehicle. Instead, the driver only needs a smart key embedded with a chip to interact with the vehicle. When the owner enters a specified range, the system recognizes the authorized driver and automatically unlocks the door. Advantages and Disadvantages of Keyless Entry: Enhanced anti-theft performance—keyless ignition locks the car's circuits, fuel system, and ignition, making it impossible to start the vehicle even if it is towed away or the anti-theft device is removed. However, modifications to the car's original wiring are usually required, which may introduce potential safety hazards.
