Do I Need to Replace the Car Lock If the Key Is Lost?

If the car key is lost, it is necessary to replace the lock. You can go to a 4S shop to replace the lock or get a new key made, and delete the data of the lost key. After deletion, the vehicle cannot be started. The specific details are as follows: 1. If it is a mechanical key, purely mechanical car keys are rare nowadays. Such keys are as simple as different door lock keys, with one key able to open the car door, trunk, and start the engine. It is best to replace all the locks on the car. 2. If it is an electronic anti-theft key, an electronic anti-theft key adds a remote control to the mechanical key. The remote control is used to open the car door or windows. If this type of key is lost, you can use the spare key to make a copy and match a new key. Although the lost key's remote control cannot open the car door, it can still forcibly open the car door, trunk, or start the engine. It is recommended to replace all the locks on the car.
I've heard quite a bit about losing keys. Actually, there's no need to rush into replacing the entire lock. When it comes to losing car keys, the key point is whether it's a regular mechanical key or a smart key with a chip. If it's a mechanical key, the risk is relatively lower because it can be easily duplicated. However, if you're worried that someone might find it and drive around your neighborhood looking for your car, it's best to replace the lock or the lock cylinder. As for smart keys, since they're linked to the vehicle's anti-theft system, simply reprogramming or getting a new key without replacing the lock can render the old key useless. It's generally recommended to first contact a 4S shop or a professional locksmith to check the key identification code and assess the local crime rate before making a decision. Don't skimp on the cost—if something really happens, insurance might not cover enough. Safety comes first. Make it a habit not to leave keys in obvious places and keep a spare hidden at home.
