Can a BMW Start Without the Key?

[DelReagan]

BMW's keyless entry system uses a smart key, so the car cannot be started if the key is forgotten. Additional Information: Keyless Entry System: The car keyless entry system, abbreviated as PKE, employs the world's most advanced RFID wireless technology and vehicle identity recognition system. It pioneers a miniaturized, low-power RF antenna solution and successfully integrates remote control with keyless systems while maintaining traditional vehicle circuit protection. This achieves a dual RF system with dual anti-theft protection, providing maximum convenience and security for the owner. Notes: As long as the smart key is within the detection range, the system automatically recognizes the authorized driver and unlocks the doors without requiring the key to be taken out or any remote operation. If the car is equipped with a keyless entry system, simply carrying the key is sufficient for use.
