What Causes a Car Key to Malfunction and the Car Not to Respond?

[OEmilio]

Car key malfunction and the car not responding are generally caused by aging of the remote transmitter antenna in the key, a dead battery, or poor battery contact. Lifespan of Car Keys: The battery in a car remote key typically lasts about 3 years. When the battery dies, you need to open the key casing to replace it. Car owners with good DIY skills can open the key casing themselves to replace the battery, as it is a relatively simple process. Precautions for Using Car Keys: Car remote keys contain a chip, so it's important to be careful not to damage the chip during disassembly. Otherwise, replacing the chip can be troublesome and costly. The casing of remote keys is generally not waterproof, so car owners should avoid submerging the key in water, as this can damage the chip. When using the remote key, try to avoid remote operations from a long distance, as this will increase battery consumption.
