Because it always emits weak radio waves, the battery runs out quickly
The "key" of the car is not a so-called key, but a "smart key" that communicates with the vehicle via radio waves. mainstream. It can be said that the analog "mechanical key" that is inserted into the key cylinder to start the engine is no longer a part of commercial vehicles.

In fact, it is not only simply exchanging on and off signals by radio waves, but also including the immobilizer, the code is changed each time to match and start.

Although it is an advanced system, it uses a standard button battery, so if you continue to use it, the battery will run out. Car manufacturers often specify replacement every two years, so there may be cases where the battery runs out without you knowing it.
Unlocking is possible with the "key" inside the smart key
What should you do if the battery runs out? First, the smart key contains an emergency mechanical key called the "blank key". Since it is prepared, it can be unlocked by pulling it out and inserting it into the key cylinder attached to the doorknob. Depending on the car model, the security may sound, but don't worry, it will disappear after the engine starts or if you leave it for a while. Click here for images
The problem is starting the engine. Many car models can be started by pressing the smart key to the start button while stepping on the brake pedal. Of course, this is an emergency method. We recommend that you replace the battery as soon as possible. By the way, in the case of a smart key, it may not work due to radio wave interference from the surroundings, so remember that it will be easier to start if you do it in the same way.

The system of the smart key itself is delicate, so when storing it, avoid leaving it in a place with strong magnetic force or high temperature. As you can see from the fact that Volkswagen has continued to use mechanical keys until recently, smart keys are convenient, but they can be frustrating and troublesome when something happens. For the time being, even if there is no trouble, please keep in mind that the smart key also needs regular maintenance.
