Instead of sending only one frequency signal as a standard key fob does smart keys send out a series of encrypted signals to the car's embedded antennas when you are near it. What does this mean?

This is a great method to ensure that new drivers are safe and it's an excellent idea for families with children in the back.

Security

Traditionally, car keys have been made of metal and used to unlock the ignition. smart keys for cars keys eliminate this requirement. Smart keys have an electronic chip that transmits a signal to the car's antenna. The vehicle 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 smart key's signal to your vehicle is encrypted, ensuring that only you have access to it. Additionally, the majority of models will stop the engine if it is not launched in the past few minutes.

The backup method is to insert the key in an opening, or keeping it close to a certain area in the cockpit where energy is transferred to an electric motor. Certain manufacturers have a mechanical key blade that can be utilized in a situation of emergency to open the trunk or to start the car.

Battery Life

The majority of modern cars have keyless entry systems and push-button starters. They are controlled by a smart device that communicates with the car via proximity technology. These systems are powered by a small transmitter that is powered by a coin-sized lithium battery. Like any other battery, it eventually needs replacement.

Most smart key fob batteries last for a while, but that doesn't mean they'll never go out of power and stop working at any time. A dead key fob means it isn't able to unlock or start the car, even if you put it near the front door. The key fob light flashes.

One single lock/unlock button takes only a tiny amount of the battery power in the fob which means that there's several years worth of signals worth of battery life left in the average smart car key reprogramming key battery.

The fob will also drain the battery if it is placed near other devices that emit electromagnetic field such as phones and computers. These gadgets emit magnetic fields of their own which can interfere with and slow down the fob's transmitter. In some instances the fob might be unable to function in the event that the fob is too close to these devices, as per RepairPal.

Maintenance
