I bought these for my 2009 FX4 after I lost a key for mine and didn't know I could just order a new key. They were easy to install and felt very durable. The locking mechanism pattern is meant to be a deterrent, so I know it works. The only thing that worries me is that they seem to be very long. but. This could be due to the aftermarket wheels I have and the cleats that come with them. They still fit, especially as I have a cap on the studs, but if there were no cap the nut would stick out a good 2 inches.
