Can car keys be reprogrammed?
3 Answers
4S stores can configure new metal keys for car owners by querying the anti-theft password for key configuration in the database based on the vehicle license and the owner's ID card provided. After the car key matching is completed, the new key will be activated, and the lost key will become invalid immediately. Even if someone picks up the old key, they can only open the car door mechanically.
Yes, car keys can definitely be re-made, and it depends on the type of key. For example, simple mechanical keys can be handled by street key stalls or 4S shops, usually costing just a few dozen yuan, which is quite convenient. However, if it's a remote key with a chip, professional equipment is required for programming; otherwise, the car won't recognize it and won't start. In this case, it's more reliable to go to a 4S shop or a professional auto service shop, and the cost may exceed a hundred yuan. I recommend bringing your vehicle documents to prove ownership when you lose a key to prevent security risks. It's wise to keep a spare key handy in daily life, so you can act quickly in case of loss and avoid delays.
Getting a new key made is certainly possible, it mainly depends on how much time and money you're willing to spend. Old-fashioned keys are cheap - a locksmith can make one in minutes, affordable and practical. But modern car keys with electronic chips are trickier; you'll need repair shops or dealerships with programming tools, potentially waiting 1-2 days with costs ranging from hundreds to several hundred yuan. I've tried saving money at small shops before, but reliability varies - best to check your car model's requirements first. Always replace lost keys promptly to prevent misuse by finders, and make safety checks a habit.
