How to Replace a BMW Key
The cost of replacing a BMW key could be expensive. BMW keys are highly-technical, and need to be
reprogrammed to function with the vehicle.
A new BMW key online will save you money, but it is important to find a seller that specializes in keys for cars and has excellent reviews. It is also recommended to visit the dealership to make sure that your new key is programmed correctly.
Smart Keys
Nowadays, a lot of new BMW cars come with an intelligent key system that lets you lock and unlock your car with just a click of a button on the steering wheel. Some models also have remote systems that allow you to start the engine and shut the sunroof and windows from an extended distance. These keys feature radio for locking or unlocking as well as infrared (IR) to communicate with the dashboard.
The IR circuit is the source of a bidirectional infrared bridge that transmits commands to and from the dashboard, and also to the receptacle in the key. This lets the key control the car from a few meters away. The key is equipped with an RF coil that picks up and transmits the remote signal to lock the car to the dashboard.
These smart keys can also store information such as the power seat and mirror settings. If you wish to share access to a friend all you have to do is pair the key with an iPhone and follow the instructions on your device. This will allow you to give them an electronic key that can be used for as long as your phone is turned on and is within Bluetooth range.
Modern smart keys, as opposed to older car key fobs that broadcast the same frequency over and over again (which could harm cars using the same system and make it easier for tech-savvy criminals to take cars), broadcast a different encrypted message each time they are used to open or close a door or pop out the trunk. The car's antennas respond by generating a corresponding frequency to recognize the key, and then unlock or turn it on.
Smart key systems may be vulnerable to hacking, however. An experienced professional can be able to be able to intercept IR transmissions and gain access to your vehicle. To safeguard yourself, keep a backup key in your vehicle or ensure that you leave the smart key at home when going out to eat or shopping. If you lose your keys, make sure to have your VIN number and ID from the government handy in the event that you require a replacement.
