I don't know if i need my starter replaced.Should I?

I have a 2003 Ford Focus and it wasn't working properly because my key wouldn't turn the ignition I've never had that problem before so i got somebody to fix it and it works but i always have to hit the key to get the key to turn so it can start, all he did was repair it, but should i get it replaced so i don't have to have this problem again?

What exactly was done to fix the problem? Here is a link - (very typical issue with earlier ford focus cars) replacing and having the ignition key cylinder re-keyed for your key is the only real fix - better to do that before the is gets so bad the ignition cylinder has to be drilled out (been there done that). http://www.fordproblems.com/trends/key-stuck-ignition/

Take it to a garage
