Duplicate car keys start from a key that still works. I use it as the reference to cut a matching blade and, where the vehicle supports it, copy or program the chip so the new key starts the car as well as opening the doors.
A duplicate is a new key made using a key you already have that works. The original shows the cuts for the blade and, on electronic keys, confirms which key type the vehicle uses. If no working key is left, it is no longer a duplicate; see lost car keys. A broken key can sometimes still help as a reference for the blade even if it no longer starts the car.
Mechanical copy versus a key that starts the car
Copying the blade is only part of the job on most modern vehicles. A cut blade can turn the door lock, but a vehicle with an immobilizer also needs a recognized transponder or smart key before it will run. Depending on the vehicle, the new key's chip is either programmed to the vehicle or, on some systems, copied from the original. Some keys can't be copied this way at all and need to be registered as an additional key.
When a duplicate isn't possible on-site
Some vehicles need every key present, manufacturer authorization or dealer equipment, and some European systems are handled only by a dealer or specialist. I check the exact year, model and key type before booking, and tell you if your key can only be copied mechanically or not at all on-site.
Adding a key from a working original is usually less expensive than an all-keys-lost job. Service call starts at $49; the final price depends on the vehicle and whether the key is a basic transponder, remote head key, flip key or proximity smart key. Every quote is given up front.
Sometimes. A snapped or worn blade may still show enough of the cut pattern, and a key code may be available for some vehicles after ownership is verified. If the broken key no longer starts the car, the electronic part is handled as adding a key. If nothing working remains, it becomes an all-keys-lost job.
For many vehicles, yes. Depending on the system, the new key's chip is programmed to the vehicle or, on some vehicles, copied. A hardware-store blade copy without a working chip may open the door but won't start the car.
For many supported vehicles, yes, when you have a working original. I pair the new key to the immobilizer, test push-button start and check passive entry before I leave. Some systems can only be handled by the dealer.
Not always. The VIN helps identify the key system, and on some vehicles it supports getting a key code after ownership is verified — but codes are only available for some vehicles, and programming support varies. Having a working original usually makes the job simpler and less expensive.
It depends on the vehicle and key type. Mechanical copies are usually quick; smart keys and some European systems take longer. If a specific key must be ordered, I schedule the visit once it arrives.
For some models and years. Mercedes-Benz, BMW, MINI, Audi, Porsche, Volvo, Land Rover and Jaguar systems vary; some can be done on-site and others need a dealer or another specialist. I check the exact vehicle first.
No. The vehicle owner or authorized driver must be on-site with photo ID and proof of ownership. That's how a legitimate locksmith operates.
