& replace your broken key.

As far as patching rather than replacing, that's within their rights under the warranty ... as long as it was in the tread and not the sidewall. Do yourself a favor though and keep an eye on the pressure in that tire for a while. Right now I'd have some concern on quality control with that shop. Patching a tire is not rocket science but it can be done wrong.

I do use a torque wrench when installing my lugs. Not to make sure I put them on tight enough but to make sure I don't put them on too tight. I'm kinda anal retentive about it nowadays. When I get new tires, I carry my torque wrench with me to the shop. When they are done, I break each lug free and re-tighten to 100 foot pounds. The reason for that is two fold: I experienced the exact same thing you did & once when my daughter's car was worked on, they didn't torque the nuts at all & she almost lost the wheel. Luckily she heard noise from the wobble before it failed catastrophically.

One final note: have the shop get their master mechanic to inspect the studs before they re-install the wheels. With that much torque, they could potentially have over stressed them.
