I'm looking to make a copy of the key for my B&W 150, preferably without having to go to the dealer. I've got the original key and the key code stamped on the side. It's a D0xy code, where x and y are different numbers.
Are there any alternatives for getting a key made, such as at a hardware shop, Home Depot, Pep Boys, etc.? If so, is there any idea of which key blank would be required?
