Where can I get a replacement spline key for my spline lug nuts?

Not all spline lugs are the same and some sellers may provide lugs not associated with your wheel brand. With different sizes and manufacturers there is no guarantee our key will fit what you have. Our spline lug kits contain a fairly standard 6 spline key. 

In order to ensure you get the right size socket you should know:

• The number of splines (6,7,10 or 12)

The easiest solution is to visit your local dealer who can remove and replace the lugs and provide a new key. Here's a link to our Dealer Locator to find a local shop that can help you: Dealer Locator

However, feel free to order from our website if you have confidence with what you need.  There are two key sizes based on the lug (wrench) hex size:

• Order Tuner (1921SD-KEY) for 19mm or 21mm lug wrench (typically car application) Link to 19mm/21mm Hex
• Order Duplex (1378SD-KEY) for 13/16 and 7/8 lug wrench (typically truck application)  Link to 13/16 and 7/8" Hex

Please remember to check your lug wrench for compatibility with your lugs and key(s).
