These do NOT come with locks!! I was very disappointed to receive these and realize this. The price I got this rack for was a good price and it is a top quality rack. However, if you care about theft protection you will have to buy lock cylinders and cross bar locks! This can add around 60$ to the price. Also if your cross bars are taller in diameter than 1 1/2 inches you will have to purchase longer screws! Bottom line is it is a great set, but no locks!!
