Smart Car Key Security Features

A smart key is in communication with your vehicle at all times regardless of whether it's in your pocket or on your desk. They communicate with each other via radiofrequency signals.

If the smart key is within range, a computer inside your car recognizes the rolling code projected by the fob of the key and validates it prior to getting the engine started. This helps thwart thieves.

Security

Many drivers are hesitant to hand over control of their car to a virtual fob via an iPhone. Security is one of the major concerns. The good news is that smart forfour key programming car keys have many of the same security features as a traditional fob.

Smart keys lock and unlock the doors by using fingerprint recognition. To use the feature, the user must place their finger on a sensor located close to or in the vicinity of the door knob or lock handle (depending on vehicle configuration). This is similar to the way smartphones and tablets with the fingerprint scanner inside operates.

Smart keys can also help protect cars by not transmitting the exact frequency signal repeatedly. If a fob sent the same signal each time it locked a door, or remotely opened the trunk, this would let thieves who are adept at technology to connect vehicles to hot wires and make them disappear. Smart keys emit a distinct signal every time a trunk or door is opened remotely.

Smart keys also can help in preventing theft of cars at gas stations and other parking spaces. This is because they transmit an extremely low-frequency signal that could be detected by the smart key in close proximity, but not by people or objects outside of the vehicle. The signal can be detected within 10 centimeters of the smart key. Therefore, it is virtually impossible for anyone to steal your car by picking up a transmission from a fob that is nearby.

Convenience

Using smart keys eliminates the need to rummage through your pockets to locate keys or lock your car using a remote control. Instead, simply tap your smartphone in the app to unlock or start the engine and drive away!

Smart keys, unlike traditional key fobs, which transmit low-power signals and communicate with your car using radiofrequency signals. The key fob comes with an encrypted chip that the antenna in your vehicle recognizes. If you reach the range of your car it will unlock the doors and/or begin the engine.

Some smart keys can also store settings for the steering wheel, mirrors and the seat. You can set them by pressing one button. This feature is becoming more popular and a rising number of manufacturers are adding it to their vehicles.

The market for car smart car key reprogramming keys is growing due to the increasing demand for safety and security features. These features reduce the wear and tear on the ignition system of a vehicle and ensure that the driver is the sole person who can stop or start the engine. Furthermore, smart keys also notify the driver when the battery is not fully charged making it harder for thieves to steal the vehicle.

Some systems allow you to unlock the door remotely in the event that the battery in your smart car key fob programming key goes out. However, it's advisable to have a spare mechanical key hidden in your wallet or in a safe place.

Autonomy

Certain smart key systems function without a key-fob in the pockets of the driver. Instead, they operate by pressing the trunk release or door handle. These systems can also be activated if a sensor detects that a driver is near.

The goal is to stop pressing a key fob during driving, allowing drivers to focus on driving safely and secure. The technology is present in a few premium cars and is gaining popularity with mainstream automakers who are trying to meet customer requirements.

Although this feature is convenient however, it can be a risk in the event that the driver does not take their key fob from the pocket prior to getting into or out of the vehicle. The reason is that smart key fobs emit an ultra-low-frequency signal that could be detected by a different device that can open the doors or pop the trunk. This is a tactic known as relay attack, and it's been used by thieves with a technological advantage to steal cars from drivers at fueling stations and also in parking areas.

However, all smart key systems offer an alternate method of opening and starting the vehicle when the battery is dead. The driver should usually insert the dead key fob inside an opening, or keep it close to a specific area in the cabin to start the emergency starter. This typically involves an inductive coil that transmits energy from the key to the vehicle.
