Key Blanks Used in All Harley Davidson Sporster Models From 1994 to Present (2017)
All 1994-2011 Harley Davidson Sportster motorcycles use HYD-13 key blanks. In 2012 Harley Davidson switched to a key blank with a longer key blade in 4 different styles or key-ways, and are used in all Sportster models from 2012 to the present. The correct key-way for your 2012 to present (2017 as of this writing) Harley Davidson Sportster can be determined from your key code series. A key code is a code used to determine the correct cuts used on your Sportster locks and is sometimes stamped on the original key, or is written on a removable tab included with your original key. Your key code series will start with a letter A, B, C or D. See photo below. A code series that starts with the letter A, uses a HYD-16 key blank, a codes series that starts with the letter B uses a HYD-15 key blank, a codes series that starts with the letter C uses a HYD-18 key blank, and a codes series that starts with the letter D uses a HYD-17 key blank.
If you don't have your key code, than use the photo below to determine which key you have. The drawing below each key blank is the shape of the lock key-way that the key fits into. It is not the shape of your key blade when looking at the tip of your key. Key blanks HYD-15 and HYD-16 use a key-way that is the mirror image of one another. Key blanks HYD-17 and HYD-18 also use a key-way that is the mirror image of one another. So, take your working Sportster key and match the grooves in your key blade to the correct key blank using the photo below.
The older style HYD-13 Sportster key blank has a key blade length of .744 inches measured from the key shoulder to the tip. The newer and longer Sportster keys have a key blade length of .920 inches measured from the key shoulder to the tip.
