How do you lock your car in an unfamiliar neighborhood?

I heard that Chrysler had a lifetime warranty at one point—that sounds too good to be true! Is it transferable?

The transmission in my 2013 Nissan Versa has always been a little off, like it kind of sticks between gears. It’s been getting worse lately and I was thinking about getting it replaced. Would that be very expensive?

My teenage daughter plays hockey and all of her gear reeks of sweat (and she does, too, if I'm being honest). Now the leather seats in my car are starting to smell funky because of how much she sweats! I obviously can't stop her from sweating, and I'd never stop her from playing hockey, but how do I get rid of the smell?
