20 inch rims on my 2012 Honda Civic lx sedan?

Price to have wheel locks removed and replaced at mechanic (W/O key)?

I bought my car used and it did not have the key to remove the wheel locks. I bought new wheel locks at the honda dealership for my 2012 honda civic. I had my car inspection done today and asked if they were able to remove my current wheel locks and replace them with the ones i have purchased. What is the typical cost of labor to have these wheel locks removed and replaced? I was told they have a particular tool used to remove the wheel locks when there's no key but i did not ask for the price.
wondering what i should expect to pay?
