Need a opinion on Wheel protection

[Yii]

Just got home today and i noticed that two of my emblems are missing on the rims. Someone that didn't no how to removed them tried prying them out or something. One is completely gone and the other is still partially there. Just the Bmw logo on the cap is missing... with obvious marks of someone sticking a screw driver or something trying to pop it out. I park my car right outside my house in a fenced off yard and the two closes wheel was the ones that were affected. Bunch of no good thieves in queens... So i need to replace these and probably order a new set but i am not worried about rim protection and where i could get OEM wheel locks and if they actually work?
