What to Do When the Remote Control of the Car Key Fails?
2 Answers
Install a new battery or go to a 4S shop specifically to have the battery installed. Open the key, dry the inside with a dry tissue, or use a hairdryer to dry it. If the water damage is severe, it is recommended to get a new one. If the car key has lost some of its functions due to prolonged contact with electronic products such as mobile phones or iPads, it is recommended to get a new one.
Having driven for decades, I've encountered remote key fob failures quite often. The most common issue is a dead battery – the CR2032 battery model can usually be found in supermarkets or convenience stores, and replacing it yourself solves the problem. If the buttons aren't responding, the key might have been dropped, gotten wet, or developed internal chip issues. In such cases, try the spare key or a reset method: hold the lock button for 10 seconds to see if the lights respond. If signal interference is particularly severe in parking lots, try moving to a different spot before attempting again. For safety, avoid stubborn attempts in remote emergency situations – prioritize using the physical key to unlock the door. Develop a habit of checking the key fob battery every six months to prevent sudden issues affecting your trip. If repairs prove impossible, visit a professional auto repair shop to scan for error codes – it's affordable, typically costing just a few hundred yuan.
