Can one use any type of lock tumbler in a Cadillac, or must it be a Cadillac of the same year and model?

I want to change the locks on my car. And are these tumblers only sold by cadillac dealers?

Helen Keller would have worn safety goggles to protect her EYEBALLS silly - NOT her sight But a plausible situation? Ummmmmmmm Hmmmmmmmmm ?????

All I can say is that it is much better when you are wearing all of your gear. I went flying in my first and only (so far) motorcycle accident. I was very happy to have all the protection of full gear. Otherwise I would have been a squid. Raw meat to the bone. All I got was black and blue, no road rash.
