pilot light on gas logs

[Dumba$$]

My gas logs went out. I tried cleaning the end of it and the vent on it. The pilot light wont stay lit, unless I hold a larger flat knift over it to hit the little rod in front of it. Then it only stay lit for about a minute then the pilot light goes out again. How can I fix this to heat my house?
