Smart Keys For Cars

Smart keys are wireless car remote that functions without the traditional mechanical blade. It can unlock the doors or open the trunk from a distance. It can also be used to start the car without turning the key.

Most smart keys come with battery indicators that notify you of low battery levels in advance. Replacing the battery is a fast and simple process that doesn't require any special tools.

Convenience

smart car key keys are designed to open trunks and doors as well as turn on the vehicle's engine and start the ignition without the driver needing to utilize a traditional metal key. They also have features that are designed to help deter break-ins and vehicle theft, like panic buttons, which makes noise to scare away possible thieves or suspicious individuals in areas with no security like underground garages with parking.

These key fobs do all this by sending an audio signal between the car and the key fob via the low-power wireless technology. This is a great feature, especially for drivers on the move and don't have a lot of time.

A smart key is typically made to look more like a plastic card than a key, and it can be used to open the trunk or doors of a car when the fob's button is pressed. Some smart keys have a touchscreen that lets drivers to control their vehicle's settings, such as the climate and audio.

The RFID signal sent between a key for smart car fob and a car is unique, encrypted and tied to the computer in the car making it nearly impossible for tech-savvy thieves to wire a stolen vehicle equipped with one. These fobs can also be programmed to send a different frequency signal every time they're used, so that the onboard computer doesn't recognize that old one as the authentic signal.

Security

Many people are reluctant to make the switch to digital car keys for the reason that they worry about security. Although having a physical key fob on hand may feel safer however, digital keys are more secure than people think. They're encrypted, and Smart Keys the signal that they send to a vehicle is analyzed with a specially-designed onboard computer. The vehicle won't be able to start when the smart key fob is stolen.

Smart keys, unlike traditional keys, operate by using the built-in antennas in your vehicle to communicate with it, and perform functions like unlocking and starting your vehicle. This system lets you gain access to your vehicle without a physical key inserted into the ignition or lock.

If you lose your smart key, or if the battery fails, most systems offer an alternative method to open and start your vehicle. Emergency starting is achieved by placing the key into a slot or holding it near a particular area of the cockpit where an inductive coil is able to transfer energy.

The majority of smart keys come with a low battery indicator that warns you before the key is completely dead. If you need to, you can easily replace the batteries on your own.

Auto-adjusting settings

Instead of the physical keys for your car Smart keys use radio waves to unlock and lock the vehicle. The smart key is also able to remotely start the engine and monitor the location of your vehicle in case you forget where you parked it.

This is very useful if have multiple drivers or wish to restrict certain features when lending your car to a new driver.

Smart keys also have the advantage of using encryption to protect against theft. This is not possible with traditional keys. This technology makes it very difficult for criminals with a technological edge to take over a vehicle by imitating a valid signal as reported by How Stuff Works Electronics. Smart keys transmit a unique, encrypted signal every time the vehicle is left unlocked or remotely opened.

As with any other device powered by batteries, a smart key's battery will eventually run out of juice. Most systems are designed with a backup strategy to open the car and start it if the battery fails. The emergency method may differ but usually it involves holding the key within the proximity to the sensor for the lock on the car or pressing a button that triggers the emergency starter.

Battery Backup

Modern smart keys, also known as keyless entry systems or passive entry, use a transmitter and receiver to unlock your vehicle. The transmitter is incorporated into the key fob that you carry with you and the receivers are located inside your vehicle and around the outside of it. When you approach the vehicle the radio frequency signal from your smart key is detected by the receivers and triggers the doors and ignition.

Although this system has many advantages, including not having to search to find keys, it could be vulnerable to certain kinds of attacks. How Stuff Works Electronics reports that if a key's battery fails or is stolen, someone could pick up the low frequency transmission signal and open your vehicle. The majority of smart key market keys are encrypted signals, which makes hacking more difficult.

If you notice that your smart key fob you purchased does not function properly, it could be caused by a problem with interference. In this case, you shouldn't put your key in proximity to such devices until the battery in the fob has been replaced.
