Can BMW car keys be duplicated?
1 Answers
Car keys can be duplicated. However, you need to bring your ID card and the vehicle's registration certificate to the corresponding 4S store to have the key duplicated. Keys duplicated elsewhere can only start the car but cannot unlock the doors. Keys duplicated at a 4S store will function the same as the original key. Functions of smart keys: When the driver approaches the car with the key in their pocket, the key and the car begin exchanging preset command information via radio waves. Subsequently, the car's locking system, security system, and engine control system are all activated. When opening the door, as soon as the driver touches the door handle, the sensor detects this pressure, and the servo motor unlocks the door while the turn signals flash twice. Then, the seat, steering wheel, and exterior rearview mirrors automatically adjust to the positions suitable for the owner. Precautions for using smart keys: Do not place the smart key together with mobile phones or computers. Many car owners habitually store their smart keys with mobile phones, laptops (or portable radios), which is actually not advisable. The frequencies from computers and mobile phones can interfere with the smart key, potentially causing malfunction in extreme cases. When near TV towers, power plants, gas stations, radio stations, large display screens, airports, or other facilities that generate strong radio waves or electronic noise, the smart key may be interfered with in extreme cases, leading to malfunction.
