Making a Key Duplicate

Model: Mercedes Sl MK 5, R129 - Years 1989-2001
Part: Key

If you need a duplicate key for these older car models, which have fairly simple technology and do not include a transponder for the immobilizer, it is just a simple mechanical key that needs to be cut to the correct pattern to open the lock. By visiting a hardware store that specializes in key duplication, you should be able to find both the blank key and the key cutting machine to duplicate the key. If you want a key that looks similar to the original, even with the manufacturer's logo, you can search online and then have the cutting done at the hardware store.
