They also come with features that are specifically designed to stop burglaries and vehicle theft, like a panic button that generates noise to scare away people who might be a threat to thieves or in areas that are isolated, such as underground garages for parking.

Key fobs can do all these things by sending a radio signal between the car and the key fob, using a low-power wireless technology. This is a great feature for drivers who are on the move and don't have a lot of time.

A smart key is usually 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 pushed. Certain smart keys include touchscreens that allow drivers to control the car's settings, including the climate and audio.

The RFID signal sent between the car and a key fob is unique, encoded and tied to the car's onboard computer. This makes it nearly impossible for criminals who are tech-savvy to connect a stolen car equipped with the key fob. Key fobs can also be programmed to transmit a new frequency signal every time they're used, meaning the computer in the car won't be able to recognize an old one as the "true" signal.

Security

A lot of people are hesitant to adopt digital keys as they are worried about security. While having a traditional key fob in hand can feel safer, digital keys are actually more secure than many think. They're encrypted, and the signal they transmit to a vehicle is verified by a computer onboard. This means that even if the smart key fob is compromised the car will not start.

Unlike traditional key fobs smart keys use built-in antennas inside 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 or starting it. This system allows you to access your vehicle without needing to insert keys that are physically placed in the ignition or lock which can be an inconvenience.

If you lose your smart keys, or if its battery is dead it is possible to find an alternative method to open and start your vehicle. Emergency starting can be achieved by placing the key into an opening, or keeping it close to an area of the cockpit where an inductive coil will transfer energy.

This is useful if you have multiple drivers or want to restrict certain features when lending your car to an inexperienced driver.

Another benefit of smart key replacement near me keys is that they employ encryption to protect against theft, which isn't feasible with traditional keys. This technology makes it very difficult for cybercriminals to hijack a car by imitating a valid frequency, reports How Stuff Works Electronics. Smart keys transmit a unique, encrypted signal every when the vehicle is unlocked or remotely opened.

The battery of a smart key will eventually wear out as does any other battery-operated device. Most systems are equipped with a backup plan to open the door and start the car if the battery fails. The emergency method varies however, it is usually holding the key within the range of the car's lock sensor or pressing a button on the key that triggers the emergency starter.

Battery backup

Modern smart keys are identified by the terms keyless entry systems or passive entry. They make use of an external transmitter to unlock your vehicle. The transmitter is situated in the key fob you carry around and the receivers are located in your vehicle and outside.

While this system offers many advantages, such as not having to fumble in the dark to find keys, it may be vulnerable to certain kinds of attacks. For instance, if the key's battery is damaged or is lost, someone else could pick up the low frequency transmission signals that are transmitted by your key and unlock your car, reports How Stuff Works Electronics. This is why most smart keys have encrypted signals to make hacking difficult.

However, these systems may also be impacted through electromagnetic fields created by cell phones, computers and other devices, so if you find that your smart key fob isn't functioning correctly, it could be caused by an interference issue. In this case you should not place your key near any such device until the battery of the fob has been replaced. Fortunately, most smart keys will notify you ahead of time if their batteries are low and the procedure for replacing the batteries is quite easy.
