They also come with features that are designed to help deter break-ins and theft of vehicles, such as panic buttons, which produces a sound to frighten away people who might be a threat to thieves or in remote areas, such as underground garages for parking.

These key fobs do all this by sending an electronic signal between the car and the key fob, using low-power wireless technology. This is a wonderful feature, particularly for drivers who are on the move and don't have a lot of time.

Smart keys are typically more like plastic cards than actual keys. They can be used to open the trunk or doors when you press a button on the fob. Some smart keys have a touchscreen that allows motorists to control their car's settings, including climate and audio.

The RFID signal that is sent between the key fob and a car is distinct, encrypted, and tied to the computer onboard this makes it virtually impossible for tech-savvy thieves to hotwire a stolen vehicle equipped with one. These fobs are also programmable to transmit a different frequency signal each time they're used so that the onboard computer can't recognize the previous one as the real signal.

Security

Many people are hesitant to adopt digital car keys for the reason that they are worried about security. While having a tangible key fob on hand may make you feel more secure, it's crucial to know that digital keys are also more secure than you think. The digital keys are secured and the signal they transmit to a vehicle is checked by an onboard computer. The car won't start in the event that the smart key fob is compromised.

In contrast to 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 standard functions like unlocking and the start of it. This system allows you access to your vehicle without having the physical key to insert into the ignition or lock.

If you lose your smart key or if its battery goes out the majority of systems provide an alternative way to open and start your vehicle. For instance, emergency starting can be accomplished by placing the key in a slot or putting it close to a certain area on the cockpit, where an inductive coil that can transfer energy is hidden.

This is helpful if are looking to restrict certain features or have multiple drivers.

Another benefit of smart keys is they employ encryption to protect against theft, which isn't a possibility with traditional keys. This technology makes it very difficult for criminals with a technological edge to gain access to a vehicle by imitating a valid frequency that is reported by How Stuff Works Electronics. smart fortwo key fob keys transmit a unique, encrypted signal every time the vehicle is left unlocked or remotely opened.

The battery of a smart key will eventually wear out as does any other battery-powered device. Most systems come with backup systems to unlock the car and start it in the event that the battery fails. The emergency procedure can differ, but it usually involves keeping the key within the proximity to the sensor for the lock on the car or pressing a button that activates the emergency start.

Battery Backup

The transmitter is integrated into the key fob that you carry around and the receivers are located in your vehicle as well as around the outside. When you get close to the vehicle the radio frequency signal from your smart key is interpreted by the receivers and activates the ignition and doors.

This system has many advantages, like not having to search in the dark to find keys, however it is susceptible to attacks of a certain type. How Stuff Works Electronics reports that if a key's battery fails or is stolen, someone could pick up its low frequency transmission signal, and open your vehicle. The majority of smart keys are encrypted signals, which makes hacking more difficult.

If you find that the smart key fob doesn't work as expected, it could be caused by a problem with interference. In this situation you shouldn't place your keys near devices like these until the battery of the device has been replaced.
