Why The Biggest "Myths" About Smart Car Key Could Actually Be True
Smart Keys For Cars
Smart keys are wireless car remote that operates without the traditional mechanical blade and can unlock doors or open the trunk from some distance. It is also able to start the car without turning the key.
The majority of smart phones have battery indicators and warn users in advance of a low battery. Replacing the battery is an easy and simple process that doesn't require any special tools.
Convenience
Smart keys are designed to open trunks and doors and turn on the car engine and activate the ignition without the driver having to use a traditional key made of metal. They also have features designed to deter vehicle burglaries and thefts. For instance, a panic key that makes sounds to frighten away criminals in remote areas such as underground garages.
Key fobs accomplish all of these functions by sending radio signals between the car and the key fob via low-power wireless technology. This is a great feature, especially for drivers on the move and do not have much time.
Smart keys generally look more like plastic cards than actual keys. They are used to unlock the trunk or doors when a button is pressed on the fob. Some smart keys have touchscreens that allow motorists to control their car's settings, including climate and audio.
The RFID signal sent between the key fob to a car is distinct, encrypted, and tied to the onboard computer which makes it nearly impossible for tech-savvy thieves to wire a stolen vehicle equipped with one. The fobs can also be programmed to transmit a different frequency signal every time they're used, to ensure 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 due to the fact that they are concerned about security. While having a tangible key fob to hand does feel more secure, it's important to realize that digital keys are also more secure than you might think. They're encrypted and the signal they send to a vehicle is analyzed by a computer onboard. This means that even if your smart key fob is compromised the car will not start.
Unlike traditional key fobs, smart keys use built-in antennas in your car and a radio pulse generator in the key fob to connect with your vehicle and perform functions such as unlocking and the start of it. This system lets you gain access to your vehicle without the physical key to insert into the ignition or lock.
If you lose your smart key, or if its battery dies, most systems offer an alternative method to open and start your car. Emergency starting is achieved by putting the key in a slot or holding it close to a specific part of the cockpit where an inductive coil can transfer energy.
Furthermore, many smart keys also have a low-battery indicator that warns you well before it is completely dead. You can easily replace the battery yourself should you need to.
Auto-adjusting settings
Instead of using the physical keys for your car Smart keys use radio waves to unlock and lock the car. They can also remotely start your engine and track the location of the vehicle should you don't remember where it's parked.
Certain smart keys are programmed to automatically adjust the interior and exterior of the vehicle depending on the key you've detected. The car will adjust the position of the seat or mirror settings as well as climate control based on which key is being used. This is useful if you want to restrict certain features or have multiple drivers.
Smart keys also have the advantage of using encryption to protect against theft. This is not a possibility with traditional keys. This makes it very difficult for thieves who are tech-savvy to take over a vehicle through replicating an authentic frequency signal, according to How Stuff Works Electronics. Smart keys send a unique, encrypted message every time the vehicle's remote is unlocked.
Just like any battery-operated device, a smart key's battery will eventually run out of juice. Most systems come with a backup system to open the car and start it if the battery fails. The emergency procedure can differ, but it usually involves keeping the key within the range of the sensor for the lock on the car or pressing a key button that activates the emergency start.
Battery backup
Modern smart keys, also referred to as keyless access systems or passive entry make use of a receiver and transmitter to unlock your vehicle. The transmitter is incorporated into the key fob you carry around with you, and the receivers are situated inside your vehicle and around the outside. The receivers detect the radio frequency signal that is sent by your smart key when you approach the vehicle and then activate the ignition and doors.
While this system comes with many advantages, including not having to search in the dark to find a key, it can be vulnerable to certain kinds of attacks. For example, if the key's battery fails or it is lost, someone else might be able to detect low frequency transmission signals that are transmitted by your key and unlock your car, according to How Stuff Works Electronics. Most smart keys have encrypted signals, which makes hacking more difficult.
However, these systems can be affected by electromagnetic fields generated by cell phones, computers and other devices, so if you find that your smart key fob is not working properly, it may be due to an interference problem. In that case it is best not to place your key in proximity to any device until the fob's battery has been replaced. Fortunately, smart forfour key will inform you ahead of time when their batteries are low and the process to replace them is fairly simple.
