Is an ID card required for key duplication?

[DeZoe]

There are three scenarios for duplicating car keys as follows: 1. Your own car: If it's your own car, simply bring your ID card, driver's license, and vehicle registration certificate. 2. Someone else's car: If it's not your own car, you'll need a signed authorization letter from the vehicle owner along with a copy of their ID card and vehicle documentation. 3. Company car: If it's a company car, present company certification and vehicle documentation. Additional information: Time required for key duplication: 1. Standard car keys: For common models like Lavida or Camry, the process typically takes one to two hours from the technician's arrival to completion. 2. Special model keys: For certain unique models such as newer Mercedes-Benz vehicles that require original manufacturer programming, the process will take considerably longer.

Ordinary door keys generally don't require ID verification. I just got two duplicates made at a street-side key cutting stall today, where the locksmith only asked whether I wanted brass or stainless steel keys. However, car keys with transponder chips are more complicated. Last week when I lost my car key and went to the 4S dealership, I not only had to bring my vehicle license but also had my purchase contract and original ID card verified. Nowadays, good car keys come with engine immobilizer systems. Making a new key requires synchronizing updates to the vehicle's computer system - technicians wouldn't dare duplicate it without proper owner identification, as they need to prevent potential car thieves who might find lost keys. I recommend keeping your spare keys safe; it's far more convenient and economical than replacing lost ones later.

The old locksmith who has been running his shop under my apartment for twenty years said: Making a regular key is like fixing a bicycle—you bring him a key blank, and he’ll make it for you. But for car electronic keys, you have to follow the official procedure. Yesterday, my friend went to get a spare key for his BMW, and the 4S store required three documents: the owner’s ID card, the vehicle registration certificate, and the photo page of the registration certificate, with the whole process recorded on video. It’s said that for high-end cars now, making a key requires syncing data with the German headquarters, and the whole set costs nearly three thousand yuan. The most cost-effective way is to keep the spare key safe when you pick up the car. I always carry two different mechanical keys in my car.

Just got back from the repair shop and noticed a detailed key duplication notice at the front desk: Mechanical keys can be duplicated anytime for 5 yuan with instant service. However, car keys with anti-theft chips require owner identity verification. Today, someone brought a Porsche key for duplication, and the staff verified the vehicle's VIN code using a tablet and performed facial recognition. Nowadays, car keys contain electronic identification codes, and dealerships must upload the new key's code to the manufacturer's cloud for matching before the engine can start. So remember to keep all keys safe. My neighbor lost two Mercedes keys last year, and the cost of replacing them was almost as much as the annual insurance premium.

As a service industry professional, I can responsibly say that key duplication falls into three scenarios: the simplest being padlock keys, which street vendors can handle; house keys depend on property management requirements, with some communities requiring ID registration. However, car keys must pass three levels of verification. Last week when helping my boss duplicate a Lexus key, the dealership pulled up three years of maintenance records and required on-site fingerprint verification. Especially for vehicles with keyless entry systems, duplicating a key is equivalent to replicating the entire vehicle's password. A reminder to everyone: never leave your vehicle registration in the car. Once, a client left their documents in the glove box, and both the car and documents were stolen, rendering the anti-theft system useless.

A researcher who has studied car key anti-theft for ten years shares: Mechanical key door locks with A-level cylinders can be directly duplicated, while B-level locks require document registration. However, automotive electronic keys involve bidirectional communication protocols. Last year, when helping a friend duplicate an Audi key, it was discovered that the new key needed to synchronize a 48-bit rolling code. At that time, a diagnostic computer was connected to the OBD interface, and a scanned copy of the owner's driver's license was uploaded to the manufacturer's database. Nowadays, smart car keys are essentially miniature computers, and duplicating keys for high-end models even requires GPS location verification of the vehicle. It's recommended to attach a number tag to the key—my keychain has a metal tag with a phone number, so anyone who finds it can contact me.
