I've had this happen to me personally on vacation - we were locked out of our rental car, asked a person at the nearby place to call a locksmith to get me back in, and they didn't quote price over the phone. When they got there, they popped the lock and then wanted $200, cash only so you couldn't chargeback, which I learned after the fact is completely outrageous for that service. They had a lot of fake Google reviews that were glowing, overshadowed by the real ones calling out the scam.

I've heard worse happening in other cases where they drill locks and then quote much higher than $200 after they do it, it's sadly common.
