How To Outsmart Your Boss On Smart Car Key
Smart Keys For Cars
A smart key is a wireless car remote that operates without the traditional mechanical blade. It can open doors or pop the trunk from some distance. It also allows you to start your car without needing to turn the key.
The majority of smart keys have indicators for batteries that warn you of an empty battery in advance. It's easy to replace the battery without special tools.
Convenience
Smart keys can open doors and trunks, as well as turn off the engine of the vehicle without the need to use a metal key. They also have features that can deter burglaries and thefts. For instance, the panic key that makes noises to deter criminals in remote areas such as underground garages.
Key fobs can perform all of these functions by sending radio transmissions between the car key fob and the car, using low-power wireless technology. This is a great convenience, especially for drivers who are often traveling and don't have time to spare.
Smart keys are generally more like plastic cards than actual keys. They are used to unlock the trunk or doors when you press a button on the fob. Some of them even have an integrated touchscreen that allows drivers to control certain settings on their vehicle, like audio and climate.
The RFID signal transmitted between the key fob and the car is unique, encoded, and connected to the vehicle's onboard computer. This makes it impossible for tech-savvy criminals to connect a stolen vehicle equipped with the key fob. These fobs are also programmable to transmit a different frequency signal each time they're used so that the computer doesn't recognize that old one as the authentic signal.
Security
A lot of people are hesitant to adopt digital keys as they are worried about security. While having a tangible key fob in your hand can feel safer, it's important to know that digital keys are also more secure than you think. They're encrypted, and the signal that they transmit to a vehicle can be verified by a special onboard computer. This means that even if your key fob is stolen the car will not start.
Unlike traditional key fobs, smart keys work by using built-in antennas in your vehicle and an electronic radio-frequency generator inside the key fob. This allows it to communicate with your vehicle and perform functions like unlocking and the start of it. This system allows you to access your vehicle without the need to insert a physical key into the lock or ignition, which is often a hassle.
If you have lost your smart key or if the battery fails the majority of systems provide an alternative way to open and start your vehicle. Emergency starting can be achieved by inserting the key into a slot or holding it close to an space in the cockpit where an inductive coil will transfer energy.
Additionally, the majority of smart keys also have a low-battery indicator that warns you before it is completely dead. If necessary, you are able to easily replace the batteries yourself.
Auto-adjusting settings
Instead of a physical car key, smart keys use radio waves to unlock and lock the car. The smart key is also able to remotely start the engine and track your vehicle's location in case you forget where you left it.
Some smart keys can be programmed to automatically adjust the exterior and interior of the vehicle according to the key that is detected. The car will adjust the position of seats as well as the settings for mirrors and the temperature control based on the key being used. This is helpful if you have multiple drivers or want to limit certain features when you loan your car to a new driver.
Smart keys also have the advantage of using encryption to prevent theft. This isn't possible with traditional keys. This technology makes it very difficult for cybercriminals to gain access to a vehicle by using a valid frequency as reported by How Stuff Works Electronics. Smart keys send a unique, encrypted message every time the remote is unlocked.
Just like any other battery-powered device the battery in a smart key will eventually run out of juice. The majority of systems have an emergency mechanism to open the car and begin it in the event that the battery fails. The emergency method varies and usually involves holding the key within range of the car's lock sensor or pressing a button on the key that triggers the emergency start.
Battery Backup
Modern smart keys, which are sometimes referred to as keyless entry systems or passive entry use a transmitter and receiver to unlock your vehicle. The transmitter is located in the key fob you carry around, and the receivers are located in and around your vehicle. The receivers are able to detect the radio frequency signal transmitted by your smart key when you approach the vehicle and then activate the ignition and doors.
This system offers many advantages, such as not having to hunt in the dark for keys, however it is susceptible to attacks of a certain type. How Stuff Works Electronics reports that if the battery of your key gets depleted or lost an attacker could detect the low-frequency transmission signal, and open your vehicle. The majority of smart keys come with encrypted signals, which makes hacking more difficult.
If you find that the smart key fob isn't able to function properly, it could be caused by a problem with interference. In that case, you should not put your key near any device until the fob's battery has been replaced. Many smart keys will notify you when their batteries are low, and the replacement process is fairly simple.
