How to Replace a BMW Key
Replacement of a BMW key is costly. This is due to the fact that
BMW keys are highly-technical and require reprogramming in order to work with your vehicle.
You can save money by purchasing a new
BMW car key on the internet, but you need to locate a dealer who is an expert in car keys and has good reviews. It is also recommended that you visit the dealership to ensure your replacement key is programmed correctly.
Smart Keys
A lot of new BMW models come with the smart-key system that allows you to lock and unlock your vehicle by simply turning the steering wheel. Additionally, certain models also come with a system that lets you start the engine from a distance, and also remotely close the windows and the sunroof. These keys are advanced and use radio for locking / unlocking and infrared (IR) to communicate with the dashboard.
The IR circuit creates an infrared bridge bidirectional that transmits commands to and from the dashboard as well as to the receptacle inside the key. This lets the key control the car from a couple of meters away. The key also has an RF coil that picks up the car's remote lock signal and transmits it to the dashboard.
These smart keys can also store information, such as the power seat and mirror settings. If you'd like to share access to a person with whom you share access all you have to do is pair the key to an iPhone and follow the prompts on your device. This will allow you give them a key that works when their phone is in Bluetooth range.
In contrast to older key fobs that transmit the same frequency repeatedly (which could affect other models and makes that use the same system, not to mention make it easier for thieves with a tech background to steal vehicles), modern smart keys transmit a distinct encrypted signal every time they are used to open or close a door, or open the trunk. The vehicle's embedded antennas then respond by generating a corresponding frequency in order to identify the key, and then unlock or open it.
Hacking is possible but not impossible. A skilled professional can intercept the IR transmissions and gain access to your vehicle. Always keep a
no spare key in your vehicle, or leave your smart key at home when you are planning to eat out or shop. If you do lose your keys, make sure to have the VIN number of your BMW and a government ID in case you need to request an exchange from the dealer.
