hey guys recently I have started to notice every time I unlock my car door I can hear the lock squeak trying to open itself. Any ideas on where this could be located and what kinda grease I should use? Also did a search for a squeaky clutch petal so I'm gunna try that out as well. As far as this goes no search is commin up. Anyways thanks in advance

 

silicone might do the trick and its not visible but white grease would be better but when it drys its white and visible
