Nokia mobile button press multiple time

[mr.ab18]

Hello,

I have Nokia e71 and there is a problem with this phone that when I press some of the keys on the keyboard, specially keys g and h, istead of pressing it once the button automatically presses more than one time. e.g. if I press g it shows in phone as ggg on the screen.

Please tell me is it a hardware problem ? The phone's keyboard is not original but some chinese keyboard installed afterward. Is there dust in the keyboard ?
