This is similar to the way a tablet or smartphone that has an embedded fingerprint scanner operates. A smart key could also help protect cars by not sending the exact same frequency signal repeatedly. If a fob sent the same signal every time it locked the door remotely or opened the trunk, this could let thieves who are adept at technology to hotwire vehicles and remove them. Smart keys emit a distinct signal every time a trunk or door is opened remotely. Smart keys also stop vehicles from being taken by thieves at fuel stations and other parking lots. They transmit a low-frequency signal that can be detected by a nearby smart key, but not by other people or objects that are not within the vehicle. The signal can be detected within 10 cm of the smart key, meaning it is not possible for anyone to steal your car by picking up a signal from a nearby fob. Convenience Smart keys eliminate the need to dig through your pockets for keys, or lock the car with a remote. Instead, simply tap your smartphone in the app to unlock the car or start the engine, and then drive away! Smart keys, unlike traditional key fobs, which transmit low-power signals and communicate with your car via radiofrequency waves. The key fob is equipped with an encrypted chip that the antenna in your car can recognize. If you reach the range of your car, it knows to unlock the doors and/or start the engine. Some smart keys also save settings for the seats or steering wheel, as well as mirrors and allow you to change them with a single click. This feature is becoming more popular, and a growing amount of manufacturers are adding this to their vehicles. The automotive smart key market is growing due to the increasing demand for security and safety features. These features decrease the wear and tear on the ignition system of a vehicle and ensure that only the driver has the ability to start or stop the engine. Additionally, smart keys can also notify the driver when the battery is not fully charged and makes it more difficult for snatchers to steal the vehicle. Certain systems also allow you to open your doors from a distance if the smart key battery dies. But, it's better to keep a spare mechanical key hidden in your wallet or other safe. Autonomy Certain smart key systems function without a key-fob in the pockets of the driver. Instead, they function by pressing the trunk release or door handle. They also operate when a sensor detects that the driver is near. The idea is to make it unnecessary to press the key fob while driving, allowing drivers to concentrate on driving safely and secure.

Smart key fobs emit low-frequency signaling that can be picked by other devices that can open doors or pop the boot. This is known as a relay, and it's used by hackers to steal cars from fueling stations as well as parking spaces. However, most smart key systems have an alternative method of opening and starting the vehicle if the battery dies. The driver typically has to place the dead key fob in an opening or keep it near a special space in the cockpit, to trigger an emergency start system, which is usually an inductive coil that transfers energy from the key to the vehicle.

Open Road Auto Group explains that traditional key fobs send out the same frequency signal each time they unlock the door, or remotely open the trunk. This implies that a hacker can potentially penetrate the system to take your vehicle. Smart car keys generate an encrypted message every time they complete some function. This makes them much harder to hack, and also more difficult for thieves who are tech-savvy to gain access to. Certain vehicles allow you to start the vehicle by walking up to it, pressing the button. These systems, unlike conventional models that require you insert and turn the keys, are powered by key fob batteries. The key fob transmits a signal to the car's antenna to signal it that you're close, and the vehicle will then open its power doors and begin the engine.
