Vehicle Smart Key Technology
Smart keys in vehicles allow drivers to open and start the car by grabbing the door handle or putting the key in the pocket. It also allows for many other adjustments like seat position, internal temperature settings and mirror position.
However, it could also cause security issues.
Security
Smart keys are key fobs that are computerized that communicate with vehicles via an embedded antenna to unlock doors and start the motor. new smart car key car key Programming (securityholes.science) key fobs, unlike traditional keys, which emit the same frequency each time they’re used, transmit encrypted signals that are only compatible with the car to which they belong. This makes it difficult for thieves who are tech-savvy to spoof or intercept the signal and use the key to take your car.
For instance, Mercedes’ system — called Keyless Go — has an internal transponder that can identify the driver’s key. When the Smart Key comes within 1.5 meters of a car, it automatically unlocks the tailgate and door, and the engine starts when a button on the key is pressed.
Additionally certain smart keyslike those made by BMW have their own user settings that let the driver adjust seat, mirrors and the steering wheel’s position and audio preferences at the touch of one button. They also come with a backup lock that stops the car from starting if the key is not in the ignition.
This technology helps drivers avoid getting their car locked accidentally particularly when they are searching the bag or purse to find keys in a parking lot with strangers or on a busy street where crime is high. Some systems will also notify drivers if the key battery is not fully charged, though this feature can vary by manufacturer.
Convenience
The smart key is perfect for those in a rush to get somewhere. You can unlock, lock and start your car simply by pressing the door handle or the trunk release. The key fob can also interact with your phone to track charging locations, charging times and other details about the vehicle, says Popular Mechanics.
You don’t want to accidentally lock your keys inside the car. The key fob communicates with an antenna within the vehicle to determine whether it’s in range. If it’s not, the engine will not start. This will deter thieves who might take your vehicle and sell its parts.
The smart car key key uses rolling codes to prevent hacking attempts and cloning, reports BMW. The vehicle’s computer can recognize and verify the code before starting the motor. Most systems come with a mechanical backup system that is a hidden key blade.
How Stuff Works Electronics notes that modern smart keys also detect the keys when it is in use and adjust the vehicle settings in accordance with the key’s use. For example, if you switch on the car while holding the key fob in your hands, the windows and sunroof can be opened to let the cabin air dry. You can also set an upper limit on speed that will only apply when the vehicle is started using the chosen key, a feature that could be useful if you loan 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 do this, hold the lock button, then press the unlock button.
This will make it impossible for your smart key fob’s smart device from being able to transmit or receive radio waves. This will significantly increase its battery life. You can always activate this function by pressing the unlock and lock buttons once more.
Certain smart keys have anti-theft features to prevent them from being copied by thieves. For example, Mercedes-Benz smart keys use rolling codes to block unauthorized access to vehicles. When the smart key is inserted into ignition, a computer in the car confirms the code in milliseconds prior to beginning the engine. BMW uses a Display Key that has a small LCD screen with a color. This allows drivers to lock their cars, open them, and start them without removing the smart key from their pocket.

Mercedes-Benz developed this technology, which is currently used by luxury car brands.
Another useful feature is that many smart key systems will operate in the event that the user forgets the key in the trunk, left it at the restaurant or if it is lost during an excursion. Certain systems will also notify the driver if the battery is not fully charged. Certain brands provide key covers specifically designed for smart keys that protect the fob from damage.
