I installed these on a 2012 Nissan Murano SL after a lame idiot left the factory OEM wheel lock key on the wheel and drove away in the car. (That idiot would be me.) LOL This design fits perfectly and looks good aesthetically and isn't noticeably different from the chrome nuts when looking at the wheel. The price was very reasonable and they arrived on time. They're on par with most other designs in terms of safety and I'm sure they can be beaten if you get creative and have some free time. (Same thing I had to do to remove the nuts from my factory key.) If someone really needs them they will find a way, but why bother with them when the next car only has standard nuts and no key required. would definitely recommend her to anyone.
