If car keys are lost, you can choose to use a spare key or contact a locksmith company. Using a spare key is the simplest and most effective method, as every car comes with a spare key provided by the manufacturer upon purchase. Below is some related information about car keys: 1. Types of car keys: Common car keys are generally divided into three types: the oldest purely mechanical keys, remote control + mechanical keys, and chip keys. 2. Documents required for key replacement: When getting a new key, you need to bring your driver's license, vehicle registration certificate, and the motor vehicle registration certificate. For different grades of vehicles, the price naturally varies, and the difference can be significant.

I also panicked when I lost my car keys last time. Don't worry, first try to recall where you last used the keys and check common spots like pants pockets or backpack compartments. If you're sure they're lost, quickly use the spare key. Without a spare, call a locksmith—they'll need vehicle information and ID to proceed. Getting a new key requires visiting a 4S shop or professional auto repair shop with your vehicle registration and ID. Matching modern chip-equipped smart keys can be quite troublesome, possibly taking several days and costing anywhere from a few hundred to over a thousand yuan. Always prepare two or three spare keys and store them separately for safety.

If the car key is really lost, safety should be the first consideration. If the car is parked on the roadside, call a tow truck to move it to a safe place, otherwise someone might drive it away with the found key. For smart keys, it's best to immediately contact the 4S store to deactivate the lost key from the system, otherwise the car might be unlocked. Temporary measures include installing a steering wheel lock or disconnecting the battery cable. The most economical way is to find a technician at an auto parts market to make a new key, but make sure they have proper qualifications. Some car insurance policies cover lost key services, so calling the insurance company can save a lot of trouble. For long-term prevention, attach a Bluetooth tracker to the keychain so the phone can track its location anytime.
