The battery indicator on a majority of smart keys will notify you when the battery is depleted. Replacing the battery is simple and doesn't require any specific tools. Simple to use In contrast to conventional keys, which require insertion into a keyhole to unlock your vehicle, smart keys rely on radiofrequency signals to communicate with your vehicle.

You can make use of an app on your smartphone to instruct the trunk of your car to open and close, or lock it. The app can also transfer digital keys to other people such as babysitters, friends or even your own. BMW's Display Key is a good example. It has a small LCD color screen that can perform the same functions as a key fob, and also some amazing features, like self-parking. In addition, the majority of smart keys come with a backup mechanical key blade, which is concealed within the key fob.

Convenient Smart keys allow you to open your door and begin your car without the traditional key fob. You simply press a button on the front door's driver side handle (or trunk handle, depending on the model you have) and you're in. The built-in antenna on the key transmits a signal to the car's tuner. The tuner then transmits a radio signal to the vehicle's lock/unlock circuits, allowing or closing the doors and trunk. Some models also come with an engine start feature that can be used even without the ignition key.

They operate on batteries and warn you if their batteries are empty. The replacement of a smart key's battery is simple and cost only a few bucks. Smart key systems generate encrypted signals that are difficult to copy by any code-stealing device. These signals are projected by the smart key and processed by a computer inside the vehicle. The computer then checks the authenticity of the key and authorize it to begin the engine. This helps to deter car thieves. Smart keys can be programmed within minutes with the assistance of a professional at your local Pop-A-Lock store. Beware of mistakes that could result in serious damage to your vehicle by carefully following the instructions.

Some systems will allow you to start your car if the fob isn't present, which is a convenient feature in the event that you forget it at home. Make Sure You're Secure A smart key makes use of radio-frequency identification (RFID) to connect with your vehicle. The chip inside the smart key is an identification code that can only be recognized by your vehicle. When the key is near, it sends a signal to the antenna on your car to unlock or lock the doors and to start the engine. If the key is out of range, the vehicle will deactivate the engine and lock its doors. Unlike conventional remote keys, smart keys are more secure from hackers. Open Road Auto Group explains that smart keys transmit a different frequency signal each time you use them, which means any other key won't take advantage of the signals to unlock your vehicle. Additionally, digital keys using UWB and BLE technologies — which aren't vulnerable to MITM attacks—are much more secure against theft. And, if you lose your digital keys it is still possible to access your car using its smartphone app. Many car keys that are digital have indicators for battery that will alert you when the battery is running low.
