Why does the car interior unlock button malfunction?
1 Answers
Car interior unlock button malfunction is caused by a dead car key battery. Below are detailed explanations regarding interior unlock failure: 1. Reasons: Besides a dead car key battery, signal interference preventing unlocking could also be the cause. If the key battery is dead, replace it; if caused by signal interference, move the car to another location to park. 2. Precautions: Car keys should not be thrown or dropped carelessly as their internal circuitry has weak impact resistance and can be easily damaged by severe collisions. Additionally, using incorrect batteries in car keys may burn out the circuit board inside the key.
