Hi, when I put the key into the lock and turn clockwise or counter clockwise, its loose and doesn't catch on to the cylinder, hence door doesn't open. I had no problem before but this key I used was a copy and I will try the original key tomorrow. I have to pickup the original key and go back to the rental property with problem lock tomorrow. Do you think I need to replace the lock if cylinder's too loose? Or is it possible that the 'copy key' is the problem. Any input would be appreciated, thanks.
