Smart Keys For Cars
Smart keys are wireless remotes which allow you to open doors and open the trunk without the necessity of a traditional mechanical blade. It also lets you start the car without having to turn the key.
The majority of smart keys come with battery indicators and will notify users in advance of a low battery. It's easy to replace the battery with no special tools.
Convenience
Smart keys are designed to open trunks and doors 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 a panic key that emits noises to scare off criminals in remote areas such as underground garages.
Key fobs fulfill all of these functions by sending a radio transmission between the car key fob and the car using low-power wireless technology. This is an excellent feature, particularly for drivers on the go who do not have much time.
A smart key is usually made to look more like a plastic card rather than a key, and can be used to open the trunk or doors of a car when a button on the fob is pressed. Some even have built-in touchscreens that allow drivers to manage certain settings on their vehicle, such as the climate and the audio.
The RFID signal that is sent between the key fob and a car is unique, secure and connected to the computer onboard which makes it nearly impossible for thieves who are tech-savvy to connect a stolen vehicle equipped with one. These key fobs can be programmed to transmit a new frequency signal each when they're utilized, so the onboard computer won't recognize an old one as the "true" signal.
Security
Many people are hesitant to adopt digital keys as they are concerned about security. While having a traditional key fob in your pocket may feel more secure however, digital keys are more secure than the majority of people believe. The digital keys are secured and the signal they transmit to a car is verified by an onboard computer. This means that even if your key fob is stolen the car won't start.
Smart keys, unlike traditional keys, operate by using the built-in antennas in your car to communicate with it and perform basic tasks like unlocking or starting your vehicle. This technology lets you access your vehicle without the need 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 dies, most systems offer an alternative way to open and start your vehicle. For instance emergency starting can be done by putting the key in a slot or holding it near a particular area on the car's cockpit, where an inductive coil that can transfer energy is hidden.
Additionally, most smart keys come with a low-battery indicator that will alert you before it is completely dead. If needed, you can easily replace the batteries on your own.
Auto-adjusting settings
Instead of physical keys rather than a physical key, the smart key uses radio waves to unlock, lock, and activate the vehicle. The smart key can also remotely start the engine and track the location of your vehicle 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 in accordance with the key it detects. The car can automatically adjust the seat position and mirror settings, as well as the temperature control based on the key that is being used. This is helpful if you have multiple drivers, or you want to restrict certain features when you lend your car to a new driver.
Another benefit of smart keys is that they employ encryption to prevent theft, which isn't a possibility with traditional keys. This technology makes it difficult for thieves with the latest technology to take over a vehicle through replicating a valid frequency signal, reports How Stuff Works Electronics. smart key G28CarKeys send a unique encrypted signal each time the vehicle is unlocked or remotely opened.
Just like any other battery-powered device the battery of a smart key will eventually deplete its juice. Most of the systems are designed with a backup method to unlock and start the car in the event that the battery fails. The emergency method can vary however, it is usually holding the key in proximity to the lock sensor on the car or pressing a button which activates the emergency starter.
Battery backup
Modern smart keys are identified by the terms keyless entry systems and passive entry. They make use of an electronic transmitter to unlock your vehicle. The transmitter is located in the key fob you carry around and the receivers can be found in your vehicle and outside. As you approach your vehicle the radio frequency signal from your smart key is interpreted by the receivers and triggers the doors and ignition.
This system comes with many advantages, like not having to look in the dark for keys, however it is susceptible to certain types attacks. How Stuff Works Electronics reports that if the battery in your key goes out or is damaged an attacker could detect the low frequency transmission signal and gain access to your vehicle. This is why most smart keys have encrypted signals that make hacking a challenge.
If you find that the smart key fob isn't able to work as expected, it could be due to a problem with interference. In this case you should avoid placing your key in proximity to any device until the battery on the key has been replaced. Fortunately, most smart keys will notify you ahead of time when their batteries are drained and the procedure for replacing them is quite simple.
