What does the keyless entry function mean?
2 Answers
Keyless entry function is an unlocking feature of a car, which means the car key has remote sensing capability. When the key is brought close to the car door, the vehicle can detect the key within a certain distance and automatically unlock. When the key moves away from the car body, the doors automatically lock and enter an anti-theft alert state. This product utilizes RFID radio frequency technology and a vehicle identity code recognition system, pioneering the development of a miniaturized, low-power RF antenna solution. It integrates the remote control system with the keyless system while maintaining traditional vehicle circuit protection, achieving dual RF systems and dual anti-theft protection, providing convenience and security for car owners.
The keyless entry feature means the car recognizes you! Every time I approach within about half a meter of the car and just touch the door handle, I hear a click as it automatically unlocks. It even saves me the trouble of taking out the key, which is especially convenient when carrying shopping bags in both hands or holding an umbrella in the rain. It works through communication between the chip in the key and the car's induction antenna, so the key can be recognized even when kept in a pocket. If the key is left in the trunk or beyond three to five meters, the car automatically locks again, providing great peace of mind against theft. Some new cars even allow you to set it to unlock only the driver's door, which is very friendly for female drivers returning late at night. Once you've used this feature, it's hard to go back to traditional keys. The only thing to watch out for is not to keep the spare key and the main key in the same car, as it can confuse the system.
