Does a car key that got wet and stopped working need to be replaced?

[MacFelicity]

If a car key gets wet and stops working, it needs to be replaced. If the buttons on the car key stop functioning due to water damage, you can take it to a 4S shop or a nearby auto parts market for repair. However, the feasibility of repair depends on the extent of damage to the circuit board. The circuit board contains many electronic components, and detailed measurements are required for repair. If the damage is not extensive, the repair time can be reasonable. Here is additional information: 1. Whether to repair: If the damage is severe, it may not be worth repairing, and you can directly replace the car key with a new one. If the motherboard is severely burned, neither the repair cost nor the time required to prepare the motherboard parts would be cost-effective. 2. Precautions: Avoid placing the key near devices such as mobile phones, laptops, or power converters. Since these radio devices emit wireless signals that can interfere with the smart key, keep the key away from such devices when in use.
