5 Smart Car Key Programming Instructions From The Professionals
Vehicle Smart Key Technology
The smart key technology in automobiles allows drivers to open 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 and internal temperature settings, mirror position and stereo presets.
However, this can also create security concerns.
Security
Smart keys are computerized key fobs which communicate with the vehicle via an embedded antenna. This allows them to unlock doors and begin the motor. Smart key fobs, unlike conventional keys that emit the same frequency each time they're pressed, transmit encrypted signals that are compatible with the vehicle to which they belong. This makes it harder for tech-savvy thieves to spoof or intercept the signal and use the key to steal your car.
For instance, Mercedes' system -- called Keyless Go -- has an internal transponder which can identify the key of the driver. The Smart Key automatically unlocks and opens the doors and 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 their own user settings that let the driver alter the seat, mirrors, the position of the steering wheel as well as audio preferences at the touch of one button. They also come with the backup lock, which will stop the car from starting if the key is not in the ignition.
try this helps drivers avoid being unable to lock their vehicle particularly when they are searching the bag or purse for keys on parking lots with strangers, or on a street where crime is high. Some systems will also notify drivers if the key battery is not fully charged, though this feature varies by manufacturer.
Convenience
If you're in a hurry get to a place the smart key makes getting into your vehicle as easy as it can be. You can lock, unlock and start your car simply by pressing a button on the door handle or the trunk release. 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 in the car. The key fob communicates with an antenna inside the vehicle to determine if it's within range. If it's not, the engine will not start. This will stop thieves from stealing your vehicle and selling its parts.
BMW reports that the smart key makes use of rolling codes as well to ward off hacking and cloning. The computer inside the vehicle detects and validates the code prior the start of the motor. The majority of systems have a mechanical back-up in the form an invisible key blade.
How Stuff Works Electronics notes that modern smart keys can also detect the key in use and adjust vehicle settings according to the situation. If you start the vehicle while holding the key in your hand, for example the windows as well as the sunroof can be opened to allow fresh air to enter the interior. You can also set a speed limit that will only be applied when the vehicle is started using the chosen key, which 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 activate this feature simply press and hold the lock button while pressing the unlock button.
This will block your smart key fob to transmit or receive radio waves. This will dramatically extend the life of your battery. You can always activate this feature by pressing the unlock and lock buttons again.
Some smart keys include anti-theft capabilities that prevent them from being stolen by thieves. For instance, Mercedes-Benz smart keys use rolling codes to stop unauthorized access to vehicles. When a smart key is inserted in the ignition, a computer inside the car validates the code in milliseconds prior to it starts the engine. BMW also has a similar system with its Display Key, which comes with a small LCD color touchscreen on the smart key for convenience, and lets drivers lock or unlock their vehicles without ever taking the key from their pockets.

When placed in the ignition of the car the computer checks the code in milliseconds. Mercedes-Benz created this technology, which is now used by luxury car manufacturers.

Some systems will alert the driver when the battery is not fully charged. Certain brands provide key covers specifically designed for smart keys that ensure that the fob is protected from harm.
