Convenience

Smart keys are designed to unlock doors and trunks and turn on the car engine and turn on the ignition without the driver having to utilize a traditional metal key. They also have features that can deter theft and break-ins, like the panic key which makes noises to frighten potential thieves in areas that are not accessible to them, such as underground garages.

The key fobs perform all this by sending a radio signal between the car and the key fob via a low-power wireless technology. This is a great feature for drivers who are on the move and do not have much time.

A smart key is usually designed to look more like a plastic card rather than a key, and it can be used to open the trunk or car's doors when the fob's button is pushed. Some even have a built-in touchscreen that lets users to control specific settings on their vehicle, like audio and climate.

The RFID signal that is sent between the key fob and a car is unique, encrypted and linked to the computer in the car, making it almost impossible for thieves who are tech-savvy to connect a stolen vehicle equipped with one. These key fobs can be programmed to send a new frequency signal every time they're used, so the onboard computer won't recognize an old one as the "true" signal.

Security

Many people are hesitant to adopt digital car keys due to the fact that they fear security. While having a tangible key fob at hand does make you feel more secure, it's crucial to recognize that digital keys are also more secure than you think. They're secure, and the signal they send to a vehicle is analyzed by a specific computer onboard. This means that even if your key fob is compromised the car won't start.

This is useful if you wish to restrict certain features or have multiple drivers.

Another benefit of smart keys is they employ encryption to protect against theft, which isn't feasible with traditional keys. This technology makes it extremely difficult for thieves with a technological edge to take over a vehicle through using a valid frequency signal, reports How Stuff Works Electronics. smart car key replacement cost keys transmit a unique encrypted signal each time the vehicle is left unlocked or remotely opened.

Just like any other battery-powered device the battery of a smart keys will eventually be depleted of power. Most systems come with backup systems to unlock the car and then start it in the event that the battery fails. The emergency method differs, but usually involves either keeping the key within the range of the lock sensor or pressing a button on the key that activates the emergency starter.

Battery backup

Modern smart car replacement key fortwo key programming (just click for source) keys, which are often referred to as keyless entry systems or passive entry use a transmitter and receiver to unlock your vehicle.

For instance, if the key's battery is damaged or is lost, someone else could detect the low frequency transmission signals from your key and open your car, according to How Stuff Works Electronics. This is why most smart keys are equipped with encrypted signals that make hacking more difficult.

However, these systems could be affected by electromagnetic fields generated by computers, cell phones and other devices. Therefore, if you find that your smart key fob isn't functioning as it should, it could be due to interference issues. In this case, you should not put your key in proximity to any device until the battery on the key has been replaced.
