How To Determine If You're Prepared For Replacement Key For Smart Car
What is a Smart Key Car Key?
Smart keys are also known as proximity keys or key fobs. They can be used to unlock doors and to start engines without having to insert physical key. They communicate with each other via radiofrequency signals.
Among other things, this helps keep cars secure by blocking attempts to connect hotwires. Smart keys also transmit unique encrypted signals to block them from being used by other drivers' vehicles.
Convenience
You can lock and unlock your vehicle without needing to insert the key into the ignition slot. Simply tap the handle of the door or trunk. Modern cars often come with a feature that allows you to start your car wirelessly. This is especially useful when you're bringing groceries in or transporting equipment and passengers.
This technology is designed to deter theft of vehicles. Instead of transmitting only one frequency signal similar to a normal key fob does it sends out an array of encrypted signals to the car's antennas embedded in it when you are near it. This prevents other cars from receiving and responding to the same signal. explaining how Stuff Works Electronics.

This is a great way to ensure that new drivers are safe and also beneficial when you have children in the back of the vehicle.
Security
Traditionally keys for cars have been made from metal and used to unlock the ignition. Smart key technology eliminates this need. Smart keys are equipped with a chip that transmits an electromagnetic signal from the antenna to your car. The car recognizes this signal when the driver presses on the trunk release or door handle. It is now impossible to lock the keys in your vehicle.
The signal that the smart key transmits to your car is encrypted, meaning that only the owner of the car can use it. A majority of models also shut down the engine if it hasn't been started in just a few minutes. This feature is especially useful if you are in an unsafe area or you have to get out of your vehicle for any reason.
In addition, if the smart key battery gets depleted during a ride, a lot of systems come with a backup plan of opening and starting the vehicle. The backup system involves placing the key into an opening, or keeping it near a particular location in the cockpit, which transfers energy to an electric motor. Some manufacturers have a motorized key blade that can be used in an emergency to open the trunk or to start the car.
Battery Life
Many newer cars have keyless entry as well as push-button starting systems which are controlled by a key fob that makes use of proximity technology to connect with the car. These systems are powered by a small transmitter which is powered by a coin-sized lithium battery. It will eventually require to be replaced just like any other battery.

It's not unusual for the transmitter inside the smart key to drain the battery. The smart key sends a signal every time you press a button. But the majority of times, it doesn't do anything. A single lock/unlock signal uses just a tiny portion of the battery power in the fob and that's several years worth of signals' worth of battery life for the average smart key battery.
The fob will also drain the battery if placed near other devices that emit electromagnetic field, such as phones and computers. These gadgets emit their own magnetic fields which can cause interference and slow down the fob transmitter. In certain cases the fob might cease to function completely when the fob is placed too close to these devices, as per RepairPal.
Maintenance
Contrary to the traditional metal car key, a smart one uses technology to manage the locks on your vehicle and perform other functions. It works by transmitting a signal from the fob to antennas located inside and outside the vehicle. These antennas receive the signal and then communicate with the computer in your car. The car interprets the signal and allows you to open or begin it without using the physical key.
New vehicles are loaded with the latest electronic technology, and the fob has become the hub for many of these functions. The most obvious are locking and unlocking, remote start, and chirping sounds to help you find your vehicle in a parking lot. Some fobs allow you to store different settings for various drivers, and remote-operated windows and the sunroof.
The fob is an intricate electronic device that includes an integrated board. It can be damaged if utilized too vigorously or exposed to extreme cold or heat. The transmitter can break if it's dropped or banged. The battery contacts may become bent.
These problems can be hard to pinpoint and solve. You can utilize your smartphone to bypass this problem to determine if it's working. However it is important to keep an extra key in your pocket or case.
