Several Reasons Why the Emgrand Cannot Detect the Key
3 Answers
The Emgrand displays 'key not detected' for three reasons: dead battery, interference, or issues with the receiver. Below are the explanations and solutions for each cause: 1. Dead Battery: If the remote control battery has been used for a long time, it may run out of power. Solution: In this case, you can only use the emergency start method first. Place the remote close to the one-touch start button to allow the car to start normally, then replace the battery as soon as possible. 2. Interference: If the remote key is too close to a mobile phone, it may sometimes be affected by the phone's signal, causing the dashboard to display 'key not detected.' Solution: Simply move the phone away to keep it at a greater distance from the key. 3. Receiver Issues: When components such as circuits or sensors are damaged, the car may fail to detect the key. Solution: Take the car to a repair shop.
As a long-term technician working in an auto repair shop, I frequently deal with the issue of Emgrand not detecting the key. The most common reason is a depleted key battery, resulting in weak electronic signals that the car cannot sense. Another common cause is internal component damage in the key, such as from being dropped or exposed to water, which prevents the signal from being transmitted correctly. Vehicle-related issues must also be considered, such as a faulty key sensing module or strong electromagnetic interference near the parking area. Placing a phone or other electronic device too close can also disrupt the signal. Additionally, key programming loss or initialization errors may occur, requiring re-matching. In emergencies, you can use the mechanical key to open the door and place the key in a specific position to force-start the car. Remember to regularly check the key battery life to avoid unexpected issues that could affect safe driving.
I've been driving an Emgrand for almost five years now, and last year I also encountered the issue of the key not being detected—it was quite a scramble. After checking, I found out the key battery was dead; replacing it with a new one solved the problem. If you leave the key in your pocket or bag for too long without maintenance, such accidents can easily happen. There are other scenarios too, like when the key is surrounded by metal objects, the signal gets blocked, or the key chip malfunctions after years of wear and tear. In places like garages or mall parking lots with lots of signal interference, the car's sensing system might fail to recognize the key. It's advisable to always carry a spare key or a mechanical key for emergencies, so you don't disrupt your plans at critical moments.
