This Is The History Of Smart Car Key Programming In 10 Milestones
Vehicle Smart Key Technology
The smart key technology in automobiles allows drivers to open and start their car by just touching the door handle, or placing the key into the pocket. It also enables a range of other adjustments, such as seating positions and internal temperature settings, stereo presets, and mirror positioning.
However, this can also lead to security concerns.
Security
Smart keys are key fobs that are computerized that communicate with vehicles via an embedded antenna. This allows them to unlock doors and start the motor. Smart keys, unlike conventional keys that emit the same frequency every time they're used, transmit encrypted signals that are only compatible with the car to which they belong to. This makes it much more difficult for thieves with a technological edge to spoof or intercept the signal and use the key to take your car.
For example, Mercedes' system -known as Keyless Go -- has an internal transponder, which identifies the key of the driver. When the Smart Key comes within 1.5 meters of a car, it automatically unlocks the door and tailgate and starts the engine when a button on the key is pressed.
Furthermore some smart keyslike those made by BMW have their own user settings that allow the driver to alter the seat, mirrors, the position of the steering wheel as well as audio preferences with the click of the button. They also come with the backup lock, which stops the car from starting if the key is not in the ignition.
This technology can prevent drivers from locking their vehicles, particularly when they have to search their purse or backpack to find keys in a parking space packed with people or on an area with high rates of crime. Many systems also notify drivers when the key is low on battery, although this feature varies by manufacturer.
Convenience
If you're in a hurry to get to a place, the smart key makes entering your vehicle as simple as it can be. By pressing the button on the trunk release or door handle you can open, lock and start your vehicle. Popular Mechanics explains that the key fob can also be used to monitor charging locations, charging, and other vehicle information.
You can't accidentally lock your keys inside the car. The key fob communicates with an antenna in the vehicle to determine if it's in range. If it's not, the engine will not start. This will stop thieves from taking your vehicle and then selling parts of it.
BMW reports that the smart key makes use of rolling codes as well to protect against hacking and cloning. The computer inside the vehicle detects and validates the code prior to launching the motor. Most systems have a physical backup system in the form of a key blade hidden in the.
How Stuff Works Electronics notes that modern smart keys can also detect the keys used and adjust the car settings accordingly. If you turn on your vehicle while holding the key in your hands for instance the windows as well as the sunroof can be opened to allow fresh air to enter the interior. You can also set the speed limit to only be in effect when the car is started with the selected key, which could be useful when loaning your car to a novice driver.
Battery Life
If you're looking for a way to get more mileage out of your vehicle's smart key, or just want to make sure it won't die during a trip to the grocery store, you can activate an auto manufacturer-specific feature called Power Saving Mode. To activate G28 Car Keys need to press and hold the lock button while pressing the unlock button.
This will block your smart key fob's smart device from being able to send or receive any radio waves. This will significantly increase the battery's life. You can reactivate this function by pressing the unlock and lock buttons again.
Certain smart keys have anti-theft functions that prevent them being copied by thieves. For instance, Mercedes-Benz smart keys use rolling codes to stop unauthorized access to the vehicle. The car's computer checks the code milliseconds after the smart key is put in. BMW offers a similar system with its Display Key, which features an LCD touchscreen on the smart key for added convenience, and allows drivers to lock or unlock their cars without ever removing the key from their pockets.
