First of all I can finally say that I have found the best wheel locks on the market. These locks take into account the fact that someone can simply pinch or bang on the outlet to attach it and knock it out. This is not possible with these locks as the outer sleeve only rotates and will by no means engage the rest of the lock with enough torque to remove it. The only option is to seriously damage the wheel until it becomes unusable. . The key itself does not have a number but does have a lock number and a sticker so you can keep it in your glove box for later use and re-order if needed. I am not sponsored in any way but I really felt compelled to write this review based on my previous experience with other locks that even sell "MASTER LOCK KEYS" to the public making them useless and a waste of money. These fools are currently looking for the easy way out and don't like to talk harshly about anything and like to get at the expense of hardworking people by stealing wheels and leaving cars completely on the ground. I hope this review will at least help prevent a person from having their drives stolen.
