smart fortwo key fob Car Key Security Features

Smart keys communicate with your vehicle constantly, whether they are in your pocket or on your desk. They communicate by using radiofrequency signals.

If the smart key is within reach, the computer inside your car detects and validates the rolling code projected from the key fob before getting the car started. This helps thwart thieves.

Security

Many drivers aren't comfortable giving control of their vehicle to a digital key on a smartphone, with security being one of the primary concerns. The good news is that a smart car key has much of the same security features as a traditional fob.

Smart keys, for instance, make use of fingerprint recognition to unlock and lock doors. To access the feature, the user must put their finger on the sensor that is placed near the door handle or the lock button (depending on the vehicle configuration). This is similar to how a tablet or smartphone that has an embedded fingerprint scanner functions.

A smart key can help protect cars by not sending the exact same frequency signal repeatedly. If a fob sent a signal every time it was unlocked or opened an trunk remotely, this could allow thieves to use hotwires to connect cars and remove them. Smart keys emit a distinct signal each time a trunk door is opened remotely.

Smart keys also help prevent vehicles from being taken by thieves at fueling stations as well as other parking spots. They transmit the signal at a low frequency that can be picked up by an adjacent smart key however, not by any other person or objects that are not within the vehicle. The signal can only be detected within 10 centimeters of the smart key, meaning it is not possible for anyone to steal your car by stealing a transmission from a fob that is nearby.

Convenience

Smart keys eliminate the need to rummage through your pockets to find a key, or lock the vehicle using a remote. Instead, you can tap your smartphone in the app to unlock or start the engine and drive away!

Smart keys, in contrast to traditional keys that transmit the signal with low power and communicate with your car through radiofrequency signals. The key fob contains an encrypted chip which the antenna in your vehicle detects. If you reach the of the car's range, it knows to unlock the doors and/or start the engine.

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

The market for automotive smart keys is booming due to increasing demand for security and safety features. These features help reduce wear on the ignition system of a car, and also ensure that only the owner can start or stop the engine. Smart keys also alert the driver if the battery is running low which makes it difficult for thieves to steal the car.

Some systems will allow you to open your door from a distance when the battery of your smart key dies. It is recommended to keep a spare mechanical key in your wallet, or in a safe place.

Autonomy

Instead of the key fob which must be kept in the pocket of the driver to unlock or start a car, some smart key systems work when the door handle or trunk release button is pressed. These systems also operate when a sensor detects the driver is nearby.

The idea is to stop pressing a key fob while driving, so that drivers can focus on driving safely and secure. The technology is already present in some high-end vehicles, and it's becoming popular among mainstream automakers trying to keep up with consumer demand.

This feature is helpful however, it could be dangerous if a driver does not take the key fob out of their pocket prior to leaving or entering the vehicle. That's because smart key fobs emit an low-frequency signal which can be picked up by a device that can open the doors, or even pop the trunk. It's a tactic called a relay attack, and it has been used by thieves with a technological advantage to take vehicles from motorists at fueling stations and even in parking lots.

Most smart key systems do come with a backup method to open and start the vehicle in the case of an insufficient battery. The driver will usually put the dead key fob into a slot, or hold it near to a designated area in the cockpit to activate the emergency starting system. This typically involves an inductive coil that transfers energy from the key to the car.

Safety

The smart key comes with integrated security features that locks the vehicle after you leave. The smart key programing key will stop the vehicle from being operated and unlock the trunk when keys are in the trunk. This will keep you from being locked out of your car in an unsafe location or while you run the errands.

Contrary to conventional keys smart key fob can communicate with the vehicle using radiofrequency signals. While it's crucial to be aware that your vehicle isn't spying on you, the fact that the key fob sends these signals makes it possible for a criminal to intercept them and take control of the vehicle.

Open Road Auto Group explains traditional key fobs emit the same frequency signal every time they unlock a door or remotely pop out of the trunk. This means a tech-savvy criminal could possibly gain access to the system and take your vehicle. Smart car keys emit an encrypted code that changes each time they carry out a function. This makes them harder to hack, and also more difficult for tech-savvy thieves to gain access to.

Certain vehicles allow you to start your car by walking towards it and pressing a button. Contrary to traditional models which require you to insert and turn the key, these systems are powered by a key fob's battery. The key fob sends the car's antenna, letting it know that you're near. The car will activate the power doors, and begin its engine.
