Convenience

Smart keys can open doors or trunks, and also turn on the engine of the vehicle without the driver needing to use a metal key. They also have features that can deter burglaries and thefts. For instance, the panic key which makes noises to scare off potential thieves in areas that are not accessible to them, such as underground garages.

Key fobs accomplish all of these functions by sending radio transmissions between the car key fob and your car using low-power wireless technology. This is a great convenience, particularly for drivers who are always in a hurry and don't have a lot of time to spare.

Smart keys are usually more like plastic cards than actual keys. They can be used to unlock the trunk or doors when they are pressed by the fob. Some of them even come with built-in touchscreens that allow users to control certain settings of their vehicle, such as climate and audio.

The RFID signal that is sent between the key fob to a car is distinct, encrypted, and tied to the onboard computer which makes it nearly impossible for hackers with the latest technology to wire a stolen vehicle equipped with one. The fobs can also be programmed to transmit a different frequency each time they're used to ensure that the computer doesn't recognize that old one as the real signal.

Security

Many people are reluctant to switch to digital keys for cars because they are concerned about security. While having a physical key fob in your pocket may feel more secure the digital keys are more secure than the majority of people believe. They're secure, and the signal that they transmit to a car is checked by a computer onboard. The vehicle won't start when the smart key fob is damaged.

Unlike traditional key fobs, smart keys operate by utilizing built-in antennas inside your vehicle and a radio pulse generator within the key fob to communicate with your vehicle and perform functions like unlocking or the start of it. This allows you to gain access to your vehicle without a physical key inserted into the ignition or lock.

Many systems offer an alternative method to start and open your car in the event that you lose your smartkey or battery dies. For instance emergency starting can be done by putting the key in the slot or keeping it close to a certain area on the cockpit, in which an inductive coil can transfer energy is hidden.

Additionally, the majority of smart car keys keys have a low-battery indicator that warns you before it goes completely dead. If needed, you can easily replace the batteries on your own.

Auto-adjusting settings

Certain smart keys come with settings that automatically adjust the vehicle's interior and exterior based on which key is detected. The car can adjust the position of seats, mirror settings and climate control depending on the type of key used. This is useful if you have multiple drivers or want to restrict certain features when you loan your car to a novice driver.

Another benefit of smart keys is that they utilize encryption to prevent theft, which isn't feasible with traditional keys. This technology makes it very difficult for tech-savvy criminals to steal a car by mimicking a valid frequency according to How Stuff Works Electronics. Smart keys send a unique, encrypted message every time the vehicle's remote is unlocked.

As with any other device powered by batteries the battery of a smart keys will eventually deplete its juice. The majority of systems have a backup system to open the car and then start it in the event that the battery fails. The emergency method may differ however it typically involves holding the key in range of the lock sensor on the car or pressing a key button that activates the emergency start.

Battery backup

Modern smart keys, which are also known as keyless entry systems or passive entry, make use of a receiver and transmitter to unlock your car. The transmitter is embedded in the key fob is carried with you and the receivers can be found inside your vehicle and around the outside of it. The receivers pick up the radio frequency signal transmitted by your smart key when you get close to the vehicle, and they then open the doors and ignition.

This system comes with many advantages, including not having to look in the dark to find keys, but it is susceptible to attacks of a certain type. For instance, 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 open your car, reports How Stuff Works Electronics. The majority of smart keys have encrypted signals, which makes hacking more difficult.

If you notice that your smart key fob doesn't function properly, it could be due to an issue with interference. In that case you should not place your key near any device until the battery of the fob has been replaced.
