A Guide To Smart Car Key Programming From Start To Finish
Vehicle Smart Key Technology

The smart key technology in vehicles allows drivers to unlock and start their car by simply touching the door handle, or putting the keys in the pocket. It also permits a variety of other adjustments, including seat positions, internal temperature settings, mirror position and stereo presets.

This can also cause security concerns.

Security

Smart keys are sophisticated electronic keys that communicate with a vehicle through one of the antennas in the car to unlock doors and begin the engine. As opposed to traditional keys, which emit the identical frequency signal each time they are pressed, smart key fobs transmit encrypted signals that only match the specific vehicle they belong to. This makes it more difficult for tech-savvy criminals to intercept or spoof the signal, and use your key to steal your vehicle.

Mercedes' Keyless Go system for instance, comes with an internal transponder which identifies the key of the driver. G28 Car Keys 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 keys- like those from BMW come with individual user settings that allow the driver to alter the seat, mirrors, steering wheel position and audio preferences at the click of a button. They also come with a backup lock, which prevents the vehicle from starting if the key is not in the ignition.

This technology prevents drivers from being unable to lock their vehicle particularly when they are searching a purse or a backpack for keys on the parking lot of strangers or on a busy street where crime is high. Some systems will also notify drivers when the battery of their key is depleted, though this feature may differ from manufacturer to the manufacturer.

Convenience

If you're in a hurry to get to a place, the smart key makes entering your car as easy as it can be. By pressing the button on the trunk release or door handle you can open, lock and get into your vehicle. Key fobs can also connect to your phone to track charging, location and other information about the vehicle, says Popular Mechanics.

One of the biggest advantages is that you aren't able to accidentally get locked out. The key fob is connected to an antenna inside the vehicle to determine whether it is within the range. If it's not, the engine will not start. This helps deter would-be thieves who would take your vehicle and sell its parts.

The smart key uses rolling codes to protect against hacking attempts and cloning, reports BMW. A computer in the vehicle reads the code and confirms it before starting the engine. Most systems have a mechanical backup in the form of an invisible key blade.

Modern smart keys also detect the type of key being used and adjust the vehicle settings in accordance with the key's use, according to How Stuff Works Electronics. For example, if you start the car while holding the key fob in the palm of your hand the windows and sunroof open to ventilate the cabin. You can also set the speed limit to only be activated when the car is powered by the chosen key. This feature is beneficial if you're lending your car to someone who has little experience.

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 from being able to transmit or receive radio waves. This will dramatically extend the life of your battery. You can always reactivate the function by pressing both the unlock and lock buttons again.


Certain smart keys come with anti-theft functions that prevent them being copied by thieves. Mercedes-Benz smart keys utilize rolling codes to prevent unauthorised access. The car's computer examines the code in milliseconds after the smart key is put in. BMW uses a Display Key that has a tiny LCD color screen. This lets drivers lock their vehicles, unlock them, and even start them without having to remove the smart key from their pockets.

Special Cases

Smart keys aren't 100 100% secure against theft, but they do aid in deterring thieves. Smart keys employ rolling security codes to protect against hacking, and when placed in the ignition, the car's computer checks the code in milliseconds. This technology was invented by Mercedes-Benz and is now utilized by many high-end car brands.

Another great feature is that many smart key systems will continue to operate even if the user has forgotten the key in the trunk, left it at a restaurant or lost it during a hike. Certain systems will also inform the driver if the battery is not fully charged. Certain brands have key covers designed specifically for smart keys, to shield the fob from damage.
