What Causes the Car Key to Fail to Be Detected?
1 Answers
If the car key suddenly fails to be detected, it may be due to the following reasons: 1. The control module inside the remote car key malfunctions, preventing detection; 2. The car's remote transmitter antenna has aged, causing the remote key to stop working; 3. Sudden cold weather may cause the grease inside the remote key to become sticky, leading to poor contact; 4. The battery in the remote car key is loose or dead. If the smart car key suddenly fails to be detected and the car door cannot be opened, you can follow these steps to open the door: First, locate the mechanical key that comes with the smart car key. Generally, smart car keys are equipped with two types of mechanical keys: one is a conventional mechanical key, which can usually be ejected by pressing a button on the key; the other is a hidden key, often located behind a safety switch on the back of the smart key, which can be accessed by sliding it open. Second, find the keyhole. The spare mechanical key usually only unlocks the driver's side door, so locate the keyhole on the door handle and open it directly. However, some car models hide the keyhole inside the door handle for aesthetic reasons. Typically, there is a small decorative panel on the right side of the handle. Insert the key to open the panel, revealing the keyhole. Third, insert the mechanical key into the keyhole to unlock the door.
