Corolla key lost treatment methods are: 1. Use the spare key to unlock; 2. Rematch the key and replace all vehicle locks. Taking the 2021 Corolla as an example, it belongs to the compact car category, with body dimensions of: length 4635mm, width 1780mm, height 1455mm, wheelbase of 2700mm, fuel tank capacity of 50l, and curb weight of 1335kg. The 2021 Corolla is equipped with a 1.2t turbocharged engine, with a maximum horsepower of 116ps, maximum power of 85kw, maximum torque of 185nm, and is paired with a 10-speed continuously variable transmission.
Last time when I lost my Corolla key, it was absolutely nerve-wracking. I immediately turned the house upside down searching for an hour, and after confirming it was gone, I promptly used the spare key to start the car. Without a spare key, it would have been a nightmare—I'd have to directly contact the nearest Toyota 4S dealership for an appointment. The dealership required bringing the vehicle registration certificate and ID card to the shop because they needed professional equipment to program the new key—the Corolla's smart key system has an encrypted chip, and without reprogramming, anyone who found the old key could still drive the car. The programming process includes deleting the old key's data—safety first, after all. Cost-wise, the smart remote key is more expensive, around 1,600 RMB, while the standard chip key starts at a cheaper 800 RMB. The whole thing took half a day to resolve. It's advisable to develop a habit of keeping spare keys safe, either hidden in the garage or entrusted to someone reliable.
