I apologize for ever making fun of people who accidentally lock their keys in their car. This is what I did (specifically, in my trunk) and this is why I called these guys.
Thankfully, my brand new 2014 Toyota Corolla had complimentary roadside assistance (which I didn't know until this happened). I called them up and they sent me a text saying these guys would come in about 30 minutes. The woman I talked to from roadside assistance reassured me by saying that they can open my car door without damaging the locks or the door.
It took them about 45 minutes to arrive. I think the guy got lost. But it didn't matter to me since he opened my car door literally within seconds. I tested my locks afterwards and they weren't broken.
I forgot his name (I'm a jerk), but he was a personable guy who explained to me how he got it open.
I didn't have to pay a penny since it was covered by Toyota roadside assistance, but I did tip him what little cash I had on me (just $2; hey, I'm a starving student). He graciously accepted and didn't seem irked or insulted that I was only tipping him such a small amount. I guess he figured out that I was a poor college student since I was at my school's parking lot.
This technician was friendly, courteous, and knew what he was doing. If he is an example of the kind of people that Pop-A-Lock employs, then I will definitely use their services in the future even if I have to pay out-of-pocket. Don't get me wrong, though. I do hope that I don't repeat this mistake.
