Vehicle Smart Key Technology

The smart key technology found in vehicles lets drivers unlock and start their car by simply touching the door handle or placing the key into the pocket. It also allows for a variety of other adjustments, like seating positions as well as internal temperature settings stereo presets and mirror positions.

However, this could also result in security issues.

Security

Smart keys are sophisticated key fobs with computers that communicate with a vehicle through one of the car’s embedded antennas to unlock the doors and to start the engine. Unlike conventional keys, which emit the same frequency signal each time they are used, smart keys transmit encrypted signals that only match the car they belong to. This makes it much more difficult for thieves with the latest technology to spoof or intercept the signal and use the key to steal your car.

For example, Mercedes’ system -known as Keyless Go — has an internal transponder that can identify the driver’s key. The Smart Key automatically unlocks and opens the doors and the tailgate when it is within 1.5 meters. It also starts the engine by pressing the key.

Additionally certain smart keyslike those made by BMW — have individual user settings that let the driver adjust the seat, mirrors and the steering wheel’s position as well as audio preferences at the push of the button. They also come with the backup lock, which stops the vehicle from running without the key.

This technology protects drivers from accidentally locking their vehicles especially when looking in a purse or a backpack for keys in an open parking lot with strangers or a busy street where crime is high. Many systems will also alert motorists when the battery for their key is low, though this feature may differ from manufacturer to manufacturer.

Convenience

The smart key also employs rolling codes to deter hacking attempts and cloning, reports BMW. The computer in the vehicle recognizes and verifies the code before starting the motor. The majority of systems have a mechanical backup system that is a key blade hidden in the.

Modern smart car key programming keys also recognize which key is in use and adjust the settings of the vehicle in line with the use of the key, says How Stuff Works Electronics. For instance, if you turn on the car holding the key fob in the palm of your hand the windows and sunroof will open to let air circulate through the cabin. You can also set a speed limit that will only apply when the vehicle is started with the selected key, which could be useful if you loan your car to a new 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 it, press down the lock button and press the unlock button.

This will block your smart key fob’s smart chip from sending or receiving radio signals that could extend its battery’s lifespan significantly. You can always restart this function by pressing the unlock and lock buttons once more.

Some smart keys have anti-theft capabilities that prevent them from being copied by thieves. For example, Mercedes-Benz smart keys use rolling codes to prevent unauthorized access to the vehicle. When the smart key is inserted in the ignition, a computer within the car smart key validates the code in milliseconds, before beginning the engine. BMW utilizes a Display Key that has a tiny LCD screen with a color. This allows drivers to lock their vehicles, unlock them, and start the engine without having to take the smart car key programmer, https://fakenews.win/Wiki/5_smart_car_key_fob_replacement_myths_you_should_avoid, key from their pockets.
