Convenience

Smart Car spare key keys are able to unlock doors, trunks and turn on the engine of the car without the driver having to use a key made of metal. They also have features that are designed to deter burglaries and theft of vehicles, such as a panic button that generates noise to scare away potential thieves or suspicious people in areas with no security like underground garages for parking.

Key fobs fulfill all of these functions via radio signals between the car key fob and the car using low-power wireless technology. This is a wonderful convenience, especially for drivers who are always traveling and don't have a lot of time to spare.

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

The RFID signal that is transmitted between a car key fob is unique, encoded and linked to the car's onboard computer. This makes it nearly impossible for hackers with the right skills to wire a stolen vehicle equipped with a key fob. Key fobs can also be programmed to transmit a new frequency signal every time they're used, so the computer in the car won't be able to recognize an old signal as the "true" signal.

Security

Many people are reluctant to adopt digital keys because they are concerned about security. While having a physical key fob in hand can feel safer but digital keys are more secure than people think. Digital keys are encrypted and the signal they send to a car is analyzed by an onboard computer. The vehicle won't be able to start when the smart key fob is compromised.

Contrary to traditional key fobs smart keys work by using built-in antennas inside your vehicle and the radio pulse generator inside the key fob to connect with your vehicle, and perform standard functions such as unlocking and starting it. This system allows you access to your vehicle without a physical key inserted into the lock or ignition.

The car can adjust the position of seats or mirror settings as well as the temperature control based on the key being used. This is beneficial if you have multiple drivers or want to restrict certain features when lending your car to a novice driver.

Smart keys also have the advantage of encryption, which can prevent theft. This isn't a possibility with traditional keys. This technology makes it extremely difficult for thieves with the latest technology to steal a vehicle by mimicking a valid frequency signal, according to How Stuff Works Electronics. Smart keys transmit a unique, encrypted message every time the vehicle's remote or unlocked.

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

Battery backup

Modern smart keys are also known by the names keyless entry systems or passive entry. They make use of an electronic transmitter to unlock your vehicle. The transmitter is integrated into the key fob you carry around and the receivers are located inside your vehicle and around the outside of it. The receivers are able to detect the radio frequency signal sent by your smart key when you enter the vehicle, and they then open the doors and ignition.

This system comes with many advantages, including not having to hunt in the dark to find keys, but it is also vulnerable to attacks of a certain type. How Stuff Works Electronics reports that if a key's battery fails or is stolen it is possible for someone to pick up the low-frequency transmission signal and open your vehicle. This is why the majority of smart keys feature encrypted signals to make hacking difficult.

However, these systems may be affected by electromagnetic fields generated by computers, cell phones and other devices. Therefore, if you find that your smart key fob is not working properly, it may be caused by interference. In this instance you should not place your key near any device until the fob's battery has been replaced. Fortunately, many smart fortwo key fob keys will warn you in advance when their batteries are running low and the process for replacing them is relatively simple.
