Have to push and turn key at same time. new SKREEM?

What is your question?

Always have to push in on the key while starting vehicle. Sometimes it engages the starter sometimes it doesnt. Do i need to replace the SKREEM?How much does this generally run? Could it be other issues. It is not responding as well as it used to, so its getting worse. And from all i have read it is not a do it yourself project
