What is the sensing distance of a smart car key?

[SimonRose]

Under normal conditions for a new car, the sensing distance of a smart car key generally ranges from 30 to 50 meters. Influencing factors: The distance of a car remote key is related to the transmitter, the battery level of the key, the car's receiving antenna, and also to obstacles around the car. Additionally, interference from other signals, such as mobile phone signals, signals emitted by other car keys being used simultaneously, and surrounding WiFi signals, can also affect it. Introduction to smart keys: Smart keys can be divided into two parts: the entry system and the start system. However, most keyless entry systems include the start function, with only a few car models having the entry function alone. The smart entry system uses advanced RFID technology. RFID (Radio Frequency Identification) is a non-contact automatic identification technology that automatically identifies target objects and retrieves relevant data through radio frequency signals. The identification process requires no manual intervention and can operate in various harsh environments.
