I over bought on what I needed so i have two sets of chrome ball seat wheels locks that will fit the OEM wheels. The packages were opened but the wheel locks were never used. Each set of four wheel locks include the key and registration card with serial number for the key. Just to be clear these are lug bolts that have a key head that needs the exact key to install or remove the lug bolts. The key head is 17MM. The lug bolts are 12 mm x 1.50. I paid full price but I am will to sell each set for 25.00 USD a piece plus shipping. Handling is free. You will only need one set for your Smart.
Also, I have two sets of the same chrome Gorilla wheel locks with cone seats for those wheels that have, well, cone seats. I was planning to use them on my summer wheel that have cone seat lug bolts. I bought three sets but only need one. So if you have after market wheels that use cone seats I have the wheels locks for them too. Same price 25.00 USD for each set.
