What is the effective range of a keyless start key?
2 Answers
Keyless start keys are effective within a range of 1-1.5 meters. Below are detailed introductions to the keyless start function: 1. Emergency braking function: During vehicle operation, if situations requiring sudden stops or engine shutdown occur, pressing the start button three or more times can immediately shut down the engine to complete braking when the vehicle is equipped with keyless start. Alternatively, if the vehicle suddenly stalls during operation, the keyless start can also be used by shifting to N gear and pressing the start button once to restart the engine. It is important to note not to press the brake pedal during the entire process. 2. Automatic power-off: The keyless start also protects the vehicle's system by automatically cutting power when the vehicle is left idle for ten minutes, preventing battery drain and protecting the battery.
As a young person who often enjoys driving around, I frequently test the range of my keyless start fob. It generally works within 1 to 3 meters, depending on the car brand and the age of the key. For example, when my car is parked on the roadside, I can easily start it while standing right in front of the door, but if I step away to about 3 meters, it stops working. Sometimes, the signal weakens when the key is in my back pants pocket. There are many influencing factors: an old key battery reduces the range—with a new battery, mine works up to 2.5 meters; interference from Wi-Fi or metal objects in the surroundings can cause intermittent signals; and for some reason, sensitivity might drop slightly on rainy days. I recommend not relying on remote operations from too far away—safety first. The system is designed this way to prevent thieves from stealing the car remotely. I’ve made it a habit to check that the key is in my pocket before getting out of the car to avoid embarrassment or delays. The battery replacement cycle is typically every two years—don’t wait until it’s completely dead to act, as that could lead to unexpected malfunctions.
