What To Look For In The Smart Car Key Programming To Be Right For You
Vehicle Smart Key Technology
The smart key technology in vehicles allows the driver to unlock and start the car simply by touching the door handle or putting the key in the pocket. It also allows for a variety of other adjustments, like seat positions, internal temperature settings, stereo presets and mirror positions.
This can also cause security concerns.
Security
Smart keys are computerized key fobs that communicate with a vehicle through one of the antennas built into the car to unlock the doors and to start the engine. Contrary to conventional keys, which emit the same frequency signal every time they are pressed, smart key fobs transmit encrypted signals that only match the car they belong to. This makes it more difficult for criminals with a technological edge to intercept or fake the signal, and use your key to steal your vehicle.
Mercedes' Keyless Go system for instance, comes with an internal transponder that can identify the driver's keys. The Smart Key automatically unlocks and opens the doors and tailgate when it is within 1.5 meters. It also begins the engine by pressing the key.
Additionally there are smart keys that- like those from BMW -- have individual user settings that allow the driver to adjust the mirrors, seat and the steering wheel's position and audio preferences at the touch of the button. They also have a backup lock that prevents the vehicle from starting if it is not connected to the key.
This technology prevents drivers from locking their cars, especially when fumbling in a purse or backpack to locate keys in a parking area packed with strangers or on an area with high rates of crime. Many systems will also alert drivers when the battery in their keys is low, but this feature may differ from manufacturer to the manufacturer.
Convenience

Popular Mechanics explains that the key fob can also be used to monitor charging location, charging status, and other vehicle information.
You shouldn't lock your keys inside the car. The key fob communicates with an antenna in the vehicle to determine if the key is in range. If it's not, the engine will not start. This is a deterrent to thieves who could steal your car to sell the parts.
BMW reports that the smart key utilizes rolling codes, as well as to ward off hacking and cloning. The vehicle's computer detects and validates the code before starting the motor. Most systems also have a mechanical backup in the form of an unnoticed key blade to be used for styling purposes.
Modern smart keys also know which key is in use and adjust the car settings in line with the use of the key, says How Stuff Works Electronics. For instance, if start the car while holding the key fob in your hand the windows and sunroof will open to ventilate the cabin. You can also set up a speed limit that will only be in effect when the car is powered by the chosen key. This feature could be beneficial if you're lending your vehicle to a person who is not experienced.
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 you need to press and hold the lock button while pressing the unlock button.
This will disable your smart key fob from sending or receiving any radio signals, which will extend its battery life significantly. You can reactivate this feature by pressing the unlock and lock buttons again.
Some smart keys also have anti-theft features that prevent them from being copied by thieves. For smart car key recoding , Mercedes-Benz smart keys use rolling codes to stop unauthorized access to the vehicle. The car's computer is able to verify the code within milliseconds following the smart key is put in. BMW makes use of a Display Key that has a tiny LCD screen with a color. This allows drivers to lock their vehicles, unlock them, and then start them without removing the smart key from their pockets.
