Is It Normal for the Car Key to Be Hot When Pulled Out?
2 Answers
It is normal for the car key to be hot when pulled out. Here are the specific reasons for the heat: 1. Sun exposure: The heat of the car key is directly proportional to sun exposure. The car ignition lock is made of metal, and the hotter the sun, the more heat it absorbs. The temperature inside a closed car under the sun can reach over 80 degrees Celsius. The thin car key inserted into the lock hole can quickly become hot, causing the car key to feel warm. 2. Light exposure: There is a light above the car keyhole, and it is not an LED light. It has a lower color temperature and emits warmth. Prolonged exposure to this light can cause the car key to heat up.
I've experienced a situation where the car key became hot after being pulled out, which is usually not normal. A regular remote key might feel slightly warm after normal use due to the internal battery or circuitry working, especially after frequent car starts or button presses. However, if it's too hot to touch, you should be cautious. Possible reasons include an aging key battery that needs replacement or a short circuit inside causing excessive current. Short-term heating could also be due to hot weather or being kept in a pocket for too long. But if it consistently gets hot, it's best to quickly try replacing the battery—it's easy to buy a corresponding model of button cell and replace it yourself. If the key still gets hot after changing the battery, don't delay—take it to a professional auto repair shop. A short circuit could potentially cause a fire, which would be a big problem. During regular maintenance, remember to keep the key away from water or moisture, and storing it in a dry place can extend its lifespan. Addressing such minor issues early can prevent problems on the road—safety first.
