How long does it take to duplicate a C-class lock key?

2-3 hours. Below is an introduction to the time required for key duplication: 1. Variation: The exact time may slightly differ depending on different vehicle brands. 2. Key matching: If it's just key matching, meaning no new key is added. The process of matching the original key with the vehicle's anti-theft system doesn't take long, usually around 2 to 3 hours, but this is under the premise of having professional maintenance diagnostic equipment and skilled technicians. 3. Lost key: If it's due to a lost key, adding or replacing a key or changing all the lock cylinders in the vehicle, the required time will be longer as it involves the security of the anti-theft system.
I've encountered quite a few cases of programming Class C car keys. As an experienced mechanic, the process usually takes between 15 to 30 minutes depending on the vehicle model and anti-theft system. For basic keys without chips, it might take just 10 minutes, but Class C locks often have electronic anti-theft chips that require OBD port programming to sync with the vehicle's computer system. From my experience helping car owners, modern vehicles typically take under 20 minutes, while Mercedes or BMW models may extend beyond 30 minutes. I recommend visiting dealerships or professional locksmiths who have proper equipment to quickly read original data, avoiding potential control module damage from roadside stalls. Remember to bring vehicle documentation and old key samples to save time. Always test both door opening and ignition after programming - the process may be brief but is absolutely crucial for security.
