Problems with my car starting

some times my car will start but other times it willnot start at all i can roll start it though it is a 2002 ford focus if anyone can give me some advice would appretiate it.

Before anyone can give you any suggestions you need to provide a much more detailed description of the problem. Start with the car - mileage and some idea of maintenance/repair history. Then describe the problem in as much detail as you can. What happens when you get in and turn the key?

How old is the battery?

What kind of advice would you like to have? Mechanical advice? Can you do mechanical things? If not, take it to a mechanic to check the starting system. The problem could be in a number of switches in the start system.
