It can also be used to start the car without turning a key. The majority of smart phones include battery indicators, which warn you in advance of a low charge. Replacing the battery is a fast and simple procedure that doesn't require any special tools. Convenience Smart keys are designed to open doors and trunks as well as turn on the vehicle's engine, and then turn off the ignition without needing to utilize a traditional metal key. They also come with features that are designed to prevent vehicle burglaries and thefts. For instance, a panic key that makes noises to scare off criminals in remote areas such as garages that are underground. Key fobs accomplish all of these functions by sending an audio signal between the car and the key fob via wireless technology that is low-power. This is a fantastic option for drivers who are often in a hurry and don't have much time to spare. A smart key is typically made to look more like a plastic card than a real key, and can be used to open the trunk or doors of a car when a button on the fob is pressed. Certain smart keys include a touchscreen that allows drivers to control their vehicle's settings, like climate and sound. The RFID signal that is sent between the car and a key fob is unique, encoded and connected to the vehicle's computer. This makes it impossible for criminals who are tech-savvy to connect a stolen car equipped with the key fob. They can also be programmed to transmit a different frequency signal each time they're used so that the onboard computer doesn't recognize the old one as the authentic signal. Security A lot of people are hesitant to make the switch to digital car keys because they are worried about security. Although having a physical key fob at hand might feel safer but digital keys are more secure than most people believe. They're encrypted, and the signal that they transmit to a vehicle is analyzed by a computer onboard. The car won't start if the smart fob is compromised. Unlike traditional key fobs, smart keys operate by utilizing built-in antennas in your car and the radio pulse generator inside the key fob. This allows it to communicate with your vehicle and perform standard functions such as unlocking and opening it. This technology allows you to gain access to your vehicle without having an actual key that you insert into the lock or ignition. Most systems provide an alternative method of opening and starting your car if you lose your smartkey or the battery goes out. Emergency starting can be achieved by putting the key in the slot, or by holding it near a particular area of the cockpit, where an inductive coil can transfer energy.

This technology makes it extremely difficult for thieves who are tech-savvy to steal a vehicle by imitating an authentic frequency signal, reports How Stuff Works Electronics. Smart keys send a distinct, encrypted signal every time the vehicle is unlocked or remotely opened. Just like any battery-operated device the battery of a smart keys will eventually run out of juice. Most systems are built with a backup system to open and start the car when the battery is not working. The emergency method varies in the majority of cases, but it involves holding the key within range of the lock sensor or pressing an appropriate button on the key which activates the emergency starter. Battery Backup Modern smart keys are also known by the names keyless entry systems and passive entry. They utilize an external transmitter to unlock your vehicle. The transmitter is integrated into the key fob you carry around and the receivers are situated within your car and around the outside of it. The receivers pick up the radio frequency signal sent by your smart key when you enter your vehicle and open the doors and ignition. This system offers many advantages, like not having to look in the dark to find keys, however it is also vulnerable to certain types attacks. How Stuff Works Electronics reports that if the battery in your key dies or is lost, someone could pick up its low frequency transmission signal, and open your vehicle. Most smart keys have encrypted signals, which makes hacking more difficult. If you find that the smart key fob doesn't work properly, this could be due to a problem with interference. In this scenario you shouldn't place your key near such devices until the battery on the fob has been replaced.
