What to Do If You Lose Your BMW Car Key?

Make every effort to search for it. If it cannot be found, you can use the spare key, but remember to go to the 4S store to deactivate the lost key. Use the password key to reconfigure a new one at the 4S store, and you need to provide the vehicle and the owner's identification documents to the 4S store.

When I lost my BMW car key, I realized the situation was a bit tricky because a BMW key isn't an ordinary one—it contains an anti-theft chip, so even if someone finds it, they can't drive the car. I quickly took out my phone and called BMW's customer service hotline, which operates 24/7. They helped me deactivate the old key to prevent theft. Next, I had to visit a BMW 4S dealership to get a new key. The technician would reprogram it using a computer, but the cost is quite high, possibly over 2,000 RMB, though insurance might cover part of it. The whole process takes one or two days, and during that time, forcing the car door open could damage the lock. I recommend everyone attach an AirTag or a tag with a phone number to their key—it makes it much easier to recover if lost next time.
