How Many Car Keys Are There?

When purchasing a new car, you generally receive two keys: one primary key and one spare key. Most modern cars are equipped with remote keys that contain electronic chips. Compared to traditional mechanical key locks, remote keys not only eliminate the need to insert and turn a key to unlock the car, enhancing convenience, but also feature highly complex encryption codes on their internal chips, providing better security. Car keys can be categorized into three types: mechanical keys, remote keys, and smartphone keys. Mechanical keys are the most common type, typically matching door locks similar to household locks, requiring insertion and rotation to unlock or lock. Their main drawback is the inability to remotely start the vehicle, making them unsuitable for certain scenarios, and they have largely been replaced by remote keys. Remote keys operate by emitting weak radio waves to control door opening and closing. Their advantages include remote start capability, greater convenience compared to mechanical keys, and the ability to remotely operate windows, trunk doors, etc. Additionally, remote keys consume less power and have longer battery life. Smartphone keys: Beyond mechanical and remote keys, some car models now utilize vehicle interaction systems, allowing smartphones to pair with the car via official platforms. When the car key is not available, the vehicle can be started or turned off using a smartphone, addressing various unexpected situations with stronger adaptability.
When buying a car, new vehicles usually come with two keys—one for primary use and one as a spare. This design is to ensure a quick replacement in case the main key is lost. Manufacturers provide this as a standard configuration. I remember a friend who lost their car key, and getting a replacement at the dealership was quite expensive, especially since many cars now have anti-theft smart chips requiring specialized equipment. So, it’s important to keep the spare key safe at home, not in the car or carried around. Additionally, if the key battery is running low, replace it early to avoid being locked out in an emergency. Overall, key management is simple—developing good habits can save a lot of trouble.
I've been driving for over a decade, and new cars always come with two keys upon delivery—one for daily carry and another kept at home as a backup. Once on vacation, I left my key in the hotel; without the spare, my family would have been stranded halfway. I recommend car owners label their spare keys for easy identification or take photos of the serial numbers for backup. If you lose a key, don't panic—dealerships can duplicate it, though it costs several hundred yuan, and even more for smart keys. Also, check the keyhole for dust buildup and clean it regularly to prevent jamming. Developing good habits like keeping an extra key is truly a lifesaver.
For young people, it's still advisable to have two basic car keys—one for daily use and the other kept as a spare for emergencies. Nowadays, smart keys are trending, and some cars even come with two sets of card-style keys, maintaining that stylish vibe. I've tried unlocking the car with a mobile app, but only after ensuring the original key is properly backed up. In daily maintenance, avoid getting the keys wet or damaging the electronic components; the battery typically lasts one to two years. A simple backup strategy makes driving more flexible and hassle-free.
