How to Replace a Car Key?
2 Answers
Remove the protective cover and key ring from the car key, then flip the key to the back side, followed by turning the car remote key to its back side. Use a tool to move along the gap of the car key's battery compartment cover towards both sides, then pry open the back cover to access and replace the battery.
A few days ago, while getting my car repaired, we talked about replacing car keys. I think the key point is the type of key. Ordinary mechanical keys are the simplest—just buy a blank key at a hardware store or auto parts shop, then have a locksmith cut the teeth. It costs just a few dozen yuan. But if it's a remote key or a smart keyless entry model, you need to be careful. They have built-in electronic chips or circuit boards and must match your car model; otherwise, the key won’t open the door or start the engine. I suggest checking the vehicle manual first or contacting a 4S store, providing the VIN and proof of ownership to confirm identity, then letting them program the new key with specialized equipment. The process might take half a day to a full day. Usually, you should protect your car keys well—don’t lose them. It’s best to prepare a spare key in advance to save trouble. If you do lose one, don’t panic—report it to the police to prevent theft, and don’t trust unauthorized shops easily.
