When you're driving and you notice that the keys on the steering wheel seem to be malfunctioning, don't worry, there are usually several possible solutions:
1. Key problem:
Maybe there's something wrong with the physical contact of the keys. Try to gently pull out the key cap with a small tool, dip a cotton swab into alcohol to clean the oxide on the contact sheet, clean up and reinstall the key cap to see if it is back to normal.
2. Air bag spring fault:
Check whether the horn function is normal. If the honking still makes a sound, then the air bag spring may not be the problem. If all the keys fail, it may be that the air bag spring has been damaged, then it should be replaced as soon as possible to ensure safety, it is recommended to carry out in professional places.
3. Cable failure:
If not just the keys, but the entire steering wheel operation is affected, there may be a problem with the spiral cable under the steering wheel. In this case, professional maintenance is essential, and replacing a new cable is the key to restoring function.
4. Damage caused by wrong operation:
Sometimes, key failure can be caused by improper use. In this case, replacing the damaged key is an effective way to correct the problem.
