What is the effective range of a car remote key?
2 Answers
The effective range of a car remote key is approximately 30 to 50 meters. The distance of a car remote key is not only related to the transmitter, the battery level of the key, and the car's receiving antenna, but also to obstacles around the car such as trees and walls, as well as signal interference, such as mobile phone signals, signals emitted by simultaneous use of car keys, and surrounding WiFi signals. If you suddenly find that the range of your car's remote key has become very short, don't worry too much. You can try testing it in a different location or replace the battery of the car key.

The effective range of a car remote key is generally said to be between 10 to 30 meters, but in practice, it can vary quite a bit. For example, in my daily driving, I've found that in open areas like parking lots, I can easily unlock the car from 20 meters away. However, when there are obstacles, like when parked near trees or behind buildings, the signal weakens to just a few meters. Electromagnetic interference also plays a role—urban areas with lots of wireless devices can halve the range. The issue becomes more noticeable as the key's battery ages, with reduced output power leading to shorter coverage, so it's advisable to replace the battery regularly. Nowadays, some high-end cars support control via a smartphone app, offering a range of over 50 meters, which is very convenient for preheating the car. If you often feel the key's range is too short, first rule out environmental factors, then check for differences in the car model itself before rushing to spend money on repairs.
