Problems starting

My daughter is driving grandpa's car and has had problems a couple times. She has had to turn the key four or five times before it finally starts. Each time she turns the key it sounds like it wants to start but will not, then finally does. Today it did it again and I was ready to leave work to go help her and it started, but she said she had to step on the brake pedal. Which does not make sense to me.

I will give it a shot when I get home for more details.

Any ideas? Battery? Starter?
