How far can the signal of a car key be received?

The longest receiving distance is about 50 meters, under ideal conditions with no electronic interference or obstacles. However, the signal is usually best and最容易 received within a range of 10 meters. The receiving distance of the remote key is also related to the quality of the key itself.

Remote keys, also known as keyless entry, allow users to remotely unlock and lock their cars without inserting the key into the lock. The main advantage is that it can be used from a distance, regardless of the time of day or night, without the need to see the lock. The system consists of two parts: the transmitter and the receiver.

The distance at which a remote key can control the car lock not only depends on the transmitter, key battery, and vehicle receiving antenna, but also on the obstacles around the car, such as walls, trees, and other electronic devices that may interfere with the signal. For example, the presence of other car keys or nearby WiFi and mobile phone signals can affect the range of the remote key.

For new cars, the range of a remote key is usually longer if the battery is full and there are fewer obstacles. However, the distance is limited for keyless entry systems, which use sensors installed in the door handles and require the key to be within a range of about 1 meter.
