Model A Ford key cut by lock cylinder code number. You supply me with the Briggs and Stratton lock Cylinder number. I cut the key by the

Number. I do Not guarantee that your lock hasn't been changed internally over the last 80 plus years though. I cut the keys from the factory numbers if your cylinder hasn't been touched my 

Keys will work just fine. These after market blanks are 10.00 each. I will ship to the US lower 48 only for 1.00 No returns. May require light filing of the sides or a few drops of oil in your lock If it is stiff. I am a Model A person just like you and have two 1930 coupes of my own so Buy with Confidence. I love these cars and want you to be happy with your purchase.
