Are Car Keys Waterproof?

Car keys are not waterproof. When a car key gets wet, do not immediately press the buttons on it, as this can easily allow moisture to penetrate the inner layers. First, dry the surface, then open the casing, remove the battery, and use highly absorbent paper towels or high-concentration alcohol to clean the internal button contact points and other areas. Use a hair dryer on the cool setting to dry the key; avoid using hot air, as the internal circuit board should not be exposed to excessive heat. Precautions for using car keys: Do not place car keys near mobile phones, as the magnetic interference from the phone may prevent the car key from functioning properly. Prolonged exposure to the phone's frequency can cause the key to malfunction. Avoid exposing car keys to high-temperature or humid environments for extended periods, and do not leave them in direct sunlight. Do not use the key continuously for long periods. Otherwise, the battery will drain, affecting its lifespan. If the key is not used for an extended period, remove the battery from the remote key and store it properly. If a vehicle's remote key is lost, the central locking system must be replaced, and two new car keys must be obtained. This is the only way to ensure the vehicle's safety and prevent criminals from finding the lost key and causing damage to the vehicle.
Most car keys on the market today have basic waterproofing. For example, my car key is labeled with an IP67 waterproof rating, meaning it can withstand short-term immersion in water without issues. However, this doesn’t mean you can swim with it or deliberately soak it, as water seeping into the key’s crevices can corrode the circuitry. If it gets wet from rain, it’s best to dry it off immediately. Last time it rained, I left my key in my pants pocket and found some moisture when I got home, so I quickly used a hairdryer on the cool setting for ten minutes. If the key actually falls into water, avoid pressing any buttons—remove the battery and use rice to absorb moisture for extra safety. Some older remote keys or cheaper car models aren’t waterproof at all; even keeping them in your pocket during car washes could damage them. Car manufacturers claim waterproofing refers to accidental splashes—no one recommends washing your car key with water. Always check the manual to confirm the waterproof rating, and it never hurts to be cautious.
