What Is Smart Car Key? Heck What Exactly Is Smart Car Key?
Smart Keys For Cars
Smart keys are wireless car remote that works without the traditional mechanical blade. It can open doors or open the trunk from an extended distance. It can also be used to start the car without turning the key.
The majority of smart phones have indicators for batteries that alert you to the low battery well in advance. It's easy to replace the battery without any special tools.
Convenience
Smart keys are designed to unlock doors and trunks and turn on the car engine, and then turn off the ignition without needing to use a traditional metal key. They also have features designed to deter vehicle burglaries and thefts, including the panic key that makes noises to deter potential thieves in isolated areas such as garages that are underground.
Key fobs accomplish all these things by sending an audio signal between the car and the key fob via low-power wireless technology. This is an excellent feature for drivers on the go who don't have a lot of time.
A smart key is typically shaped more like a plastic card than a real key, and can be used to open the trunk or car's doors when the fob's button is pushed. G28 come with built-in touchscreens that allow users to control certain settings of their vehicle, like audio and climate.
The RFID signal sent between the car and a key fob is unique, encoded and linked to the vehicle's onboard computer. This makes it impossible for tech-savvy criminals to wire a stolen vehicle equipped with the key fob. These fobs can also be programmed to transmit a different frequency every time they're used, so that the computer isn't able to recognize the old one as the genuine signal.
Security
Many people are reluctant to adopt digital car keys because they fear security. While having a physical fob in hand can feel safer however, digital keys are more secure than many believe. They're secure, and the signal they transmit to a vehicle is verified by a special onboard computer. The vehicle won't start in the event that the smart key fob is stolen.
Smart keys unlike traditional keys, operate by using the built-in antennas of your vehicle to communicate with it and perform basic functions like unlocking and launching your vehicle. This system allows you to access your vehicle without having to insert keys that are physically placed in the lock or ignition, which is often a hassle.
If you lose your smart key, or if its battery is dead there is an alternative way to open and start your vehicle. For instance, emergency starting can be done by putting the key into a slot or putting it near a specific area on the car's cockpit, where an inductive coil which can transfer energy is hidden.
Many smart keys also come with a low battery indicator, which will alert you when the key is dead. If necessary, you are able to easily replace the batteries yourself.
Auto-adjusting settings
Rather than using physical keys, the smart key uses radio waves to unlock and lock the car. The smart key can remotely start the engine and monitor your vehicle's location in case you don't remember where you parked it.
Some smart keys are programmed to automatically adjust the exterior and interior of the vehicle based on the key detected. For example the car can detect the key you're using and automatically adjust the seating position, mirror settings and the climate control. This is beneficial if you are looking to restrict certain features or have multiple drivers.
Another benefit of smart keys is that they use encryption to protect against theft, something that isn't possible with traditional keys. This technology makes it extremely difficult for criminals with a technological edge to hijack a car by imitating a valid frequency, reports How Stuff Works Electronics. Smart keys send a unique, encrypted signal every when the vehicle is unlocked or remotely opened.
Like any other battery-powered device the battery of a smart key will eventually be depleted of power. The majority of systems are designed with a backup method to unlock and start the car if the battery fails. The emergency method differs however, it is usually holding the key within range of the car's lock sensor or pressing the key with a button that activates the emergency starter.
Battery Backup
Modern smart keys, often referred to as keyless entry systems or passive entry make use of a receiver and transmitter to unlock your car. The transmitter is incorporated into the key fob is carried with you and the receivers are situated within your vehicle and around the outside of it. When you get close to the vehicle the radio frequency signal from your smart key is picked up by the receivers and triggers the ignition and doors.
Although this system has a number of advantages, such as not having to search for the key, it can be vulnerable to certain types of attacks. How Stuff Works Electronics reports that if your key's battery goes out or is damaged it is possible for someone to pick up the low-frequency transmission signal and then open your vehicle. This is why the majority of smart keys are equipped with encrypted signals to make hacking more difficult.
However, these systems may be affected by electromagnetic fields produced by cell phones, computers and other devices. If you notice that your smart key fob isn't functioning as it should, it could be caused by interference. In this situation you should not place your keys near devices like these until the battery of the fob has been replaced. Fortunately, many smart keys will inform you well in advance when their batteries are low and the process for replacing them is relatively simple.
