Hyundai Accent 2002 starter engine

Best good morning!
It will be that they help me detect the problem I have with the starter engine of my car. Hyundai Accent 2002.
When giving the key to the key, it feels and listens to skating the starter engine, emits a buzz.
What can I do, have material to give me ???

It may be that this stuck that drives the Bendix to grab the steering wheel being ...
sometimes that problem is solved by slightly sticking the seleneoid with a tip and crown key to take off.
The other problem is that the selenoid has burned. But it's difficult.
luck

When listening as a dramel it is because it turns but it does not usually come out if so then the problem is the solenoid if it comes out but revolves on whether the axis is the vendix, take out the start and put it on a bank screw put it out and see if it comes out and enter if it does it let it turn outside and with a stick it precious the vendix if it stops that is the problem you replace it and now.
