The cost of replacing the BMW key can be costly. BMW keys are high-tech, and need to be reprogrammed in order to work with the vehicle.

The purchase of a new BMW key online can save you money, however it is important to find an online retailer that is specialized in keys for cars and has excellent reviews. It is also recommended to visit a dealership to make sure that your replacement is programmed correctly.

Smart Keys

Many new BMW models are equipped with a smart-key system that allows you to lock and unlock your vehicle by simply turning the steering wheel. Certain models also come with remotes that allow you to start the engine and shut the windows and sunroof from a distance. These keys feature radio for locking or unlocking and infrared (IR) to communicate with the dashboard.

The IR circuit powers a bidirectional infrared bridge that sends commands to and from the dashboard as well as to the receptacle in the key. The key can control the car from a distance of a few metres. The key also has an RF coil that detects the car's remote lock signal and transmits it to the dashboard.

These smart keys also have the ability to store information such as mirror and power seat settings. To give access to someone else, you just need to pair the key to an iPhone and then follow the directions on your device. This will allow you give them a key that works as long as their phone is on and within Bluetooth range.

Modern smart keys, as opposed to older key fobs for cars that transmit the same frequency continuously (which could impact cars that use the same system and make it easier for tech-savvy criminals to take cars), broadcast a different encrypted message each time they're used to open or close a door or pop out the trunk. The vehicle's embedded radio antennas respond by emitting the appropriate frequency to identify the key, unlock it or open it.

Smart key systems may be vulnerable to hacking, however. A skilled professional can snoop on IR transmissions to gain access to your vehicle. Always keep a spare key in your vehicle, or leave your smart key at home when you are going to go out to eat or shop. If you do lose your keys, be sure to keep the VIN number of your BMW and government ID available in case you have to get a replacement bmw key fob from a dealer.
