1977 Mercedes Benz 300d

I need to have my ignition key replaced for my 1977 Mercedes 300d. How do I get a blank key. I have the code, and live no where around a dealer. Help! Im stuck out in the cuts until I can get a new key.

The easiest way to get a key made is remove the passenger side door handle and take it into a locksmith and he will cut you a key, the car is too old I don't think you will find anyone that can decipher the key code.
