Smart Keys For Cars

Smart keys are wireless remotes that allow you to unlock doors and open the trunk without the necessity of a traditional mechanical blade. It also lets you start the vehicle without having to turn a key.

Most smart keys come with indicators for battery levels that notify you of the low battery well ahead of time. It's easy to replace the battery with no special tools.

Convenience

Smart keys are designed to unlock trunks and doors, turn on the car engine and activate the ignition without having to use a traditional key. They also come with features that help deter vehicle burglaries and thefts, including the panic key which makes noises to frighten potential thieves in isolated areas such as underground garages.

Key fobs can perform all of these functions by sending an audio signal between the car key fob and the car using low-power wireless technology. This is a fantastic feature for drivers on the move who don't have a lot of time.

A smart key is usually made 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 the fob's button is pushed. Some even have a built-in touchscreen to allow users to control certain settings on their vehicle, like climate and audio.

The RFID signal transmitted between a key fob and car is unique, encoded, and connected to the vehicle's computer. This makes it nearly impossible for hackers with the right skills to connect a stolen vehicle equipped with the key fob. These fobs can also be programmed to send a new frequency signal each time they're used. This means that the computer that's onboard won't recognise an old one as the "true" signal.

Security

Many people are hesitant to use digital keys for their car due to the fact that they worry about security. While having a physical key fob in hand can feel more secure however, digital keys are more secure than most people believe.

This is helpful if you have multiple drivers or want to restrict certain features when you lend your car to a novice driver.

Another benefit of smart keys is that they utilize encryption to stop theft, which isn't feasible with traditional keys. This makes it very difficult for thieves who are tech-savvy to take over a vehicle through replicating a valid frequency signal, reports How Stuff Works Electronics. Smart keys send a distinct, encrypted signal every time the vehicle is left unlocked or remotely opened.

The battery of a smart key will eventually run out, just like any other battery-operated device. The majority of systems have a backup system to open the car's doors and start it if the battery fails. The emergency method differs in the majority of cases, but it involves holding the keys within the range of the lock sensor or pressing the key with a button which activates the emergency starter.
