If the smart key is within the range of the computer in your car will recognize and verify the rolling code projected from the key fob prior to beginning the engine. This helps deter thieves.
Security
Many drivers are wary of giving control of their vehicle to a virtual key on a smartphone, with security being one of the primary concerns. The good news is that the smart car key comes with much of the same security features as a traditional fob.
For starters, smart keys make use of fingerprint recognition to unlock and lock doors. To use the feature, a person must put their finger on the sensor near or inside the lock button or door handle (depending on vehicle configuration). This is similar to how a phone or tablet equipped with an embedded fingerprint scanner function.
A smart key can help to protect vehicles by not transmitting the exact frequency signal repeatedly. If a fob transmitted the same signal each time it unlocked a door, or remotely opened the trunk, it would permit thieves with a tech-savvy mindset to use hotwires to make them disappear. Fortunately, this isn't an issue because smart keys emit a distinct encrypted signal each when the door is opened or the trunk is remotely opened.
Smart keys can also help to stop cars from being stolen at gas stations and other parking spaces. This is because they transmit a low-frequency signal that can be detected by a nearby smart key, but not by people or objects that are not within the vehicle. The signal is detectable only within 10 centimeters of the smart key. Thus, it is impossible to take your vehicle away by taking a transmission.
Convenience
Smart keys eliminate the need to rummage through your pockets for keys or to lock your vehicle using remote. You can unlock your car and start it by tapping the app on your phone.
As opposed to traditional key fobs that transmit a low-power signal, smart keys communicate with your vehicle using radiofrequency signals. The key fob contains an encrypted chip that the antenna inside your car recognizes. If you're within reach of your vehicle it will unlock the doors or begin the engine.
Some smart keys can also store settings for the steering wheel, mirrors and the seat. You can then alter them by pressing one button. This feature is becoming more popular, and an increasing amount of manufacturers are adding this feature to their vehicles.

These features minimize the wear and tear of the ignition system in a car and ensure that the driver is the sole person who can stop or restart the engine. Smart keys can also inform the driver when the battery is low which makes it difficult for thieves to steal the vehicle.
Certain systems will also allow you to open your doors from a distance in the event that the battery of your smart key dies. It is best to keep a mechanical backup key in your wallet, or in a secure location.
Autonomy
Some smart key systems operate without a key fob in the pockets of the driver. Instead, they function by pressing the trunk release lever or door handle. These systems also operate when a sensor detects the driver is nearby.
The idea is to eliminate the necessity of pressing the key fob while driving, so drivers can concentrate on driving safely and securely. The technology is available in some luxury vehicles and is gaining traction among major automakers trying to keep up with the customer demand.
While this feature is convenient but it could be risky in the event that the driver does not take their key fob from the pocket prior to going into or out of the car. That's because smart key fobs emit an ultra-low-frequency signal that could be picked up by a device that can unlock the doors or open the trunk. This is a technique known as a relay, and it's been used by cyber-savvy criminals to steal cars at fueling stations as well as parking spaces.
However, many smart key systems include an alternate method of opening and starting the car if the battery dies. The driver usually must put the dead key fob in an opening or keep it in a specific area in the cockpit to trigger an emergency starting system, which usually involves an inductive coil which transfers energy from the key to the vehicle.
smart forfour key replacement comes with a built-in security feature that will lock your vehicle when you leave. It will even shut down the engine and open the trunk if you've put the keys in. This will prevent you from being locked out of your vehicle in an unsafe location or when running errands.
Unlike conventional keys, a smart key fob connects to the vehicle via radiofrequency signals. While it's important to remember that your vehicle isn't spying however, the fact that the key fob transmits these signals makes it possible for a criminal to intercept them and gain control over the vehicle.
Open Road Auto Group explains that traditional key fobs emit the same frequency signal each time they open the door, or remotely open the trunk. This means that a cyber-savvy criminal could potentially gain access to the system and take your vehicle. Smart car keys, however, send out an encrypted signal each time they are used. This makes them harder to crack, and more difficult for tech-savvy thieves to exploit.
Certain vehicles allow you to start your car by walking towards it and pressing the button. Instead of traditional models that require you to insert and turn the key and then turn it on, these systems are powered by a key fob's battery. The key fob sends an indication to your car's antenna, telling it that you're within. The car will activate the power doors, and start its engine.
