How do you replace car keys for a Jeep Wrangler?

Yesterday on my way home from work I noticed my brakes were acting weird. It sort of feels like they’re “skipping”, almost, like my foot is held down with steady pressure, and the brakes get loose and then get firm again. I’m not driving the car until I get to a mechanic, but what can make brakes feel like they are skipping?

There’s something wrong with the tires on my Audi, but I can’t afford to replace or repair them. I’m still under warranty but not sure where to find information about whether my tires are covered or not. I really don’t want to pay for it only to learn that it was actually covered. Will my Audi warranty cover tires?

I am in the process of moving homes. However, I also just found my dream vacation home and don’t want to wait. Can I buy two houses at the same time?
