What to Do When the Spare Key Doesn't Work?
2 Answers
There are several possible reasons: The spare key's battery is dead. The vehicle's central locking system has malfunctioned. The vehicle's onboard computer data is corrupted. You need to replace the key's battery. If the car door still cannot be unlocked, you should contact the 4S store's after-sales department. Related information is as follows: 1. Storage location: The spare key for motor vehicles can be kept at home, in the office, or even in a friend's car. As long as you can quickly access the spare key when needed, there should be no problem. Note that the spare key should not be stored inside the vehicle itself. If accidentally locked inside, it can cause inconvenience. 2. Spare battery: The spare key should not be stored in damp or dark places, nor in direct sunlight. The storage location for the spare key should also contain spare batteries, as prolonged storage may cause the spare key to lose power, affecting its normal use. Otherwise, the purpose of having a spare key is defeated.
That day I drove to a gathering and then went home, only to find that the spare key couldn't turn when inserted into the car, and the car wouldn't start at all. At first, I thought the battery was dead, but replacing it with a new one didn't help. Upon closer inspection, the remote control light wasn't even on, probably because the internal chip was damaged. Later, I recalled that this key had been soaked in water by my son while playing, likely causing a short circuit. Unable to wait for repair services, I had to call a friend to pick me up. The next day, I took it to the auto repair shop for inspection, and sure enough, the electronic components of the key were faulty. It cost me 200 yuan to get a new one. The lesson is: don't leave spare keys lying around or let children play with them, and it's important to check their functionality regularly, especially since smart keys are prone to moisture damage. Proper maintenance, like testing the spare key every three months, can help avoid such troubles.
