Change the lock yourself. You don't need a locksmith. Just get a new lock. They aren't all that expensive..
And any asshole can teach himself to "rake" the cheap ones in an hour of practicing. Real world you could get it in 30 seconds or less depending on how cheap you went and the luck factor. It requires virtually no skill at all, at least even semi-decent locks require some sort of skill to defeat. The man is worried about someone having a key to his house after all, buying the cheapest lock you can get gives virtually anyone with $20 and a few minutes with YouTube a key.
Whatever. You can buy quality locks for around 50 bucks easy at any home depot. I never said buy the cheapest shit he can get.
He can get a locksmith or not. Makes no difference to me, It was just a suggestion.
who the hell locks the bathroom door anyways?
Even a $50 lock is easily pickable and even easier to bump. You gotta spend some serious cake to get a high-security lock or have a locksmith install security pins. The security pins won't make it pick or bump proof but it will make them fairly resistant so that it's likely the person trying to get in would move on.
You gotta remember that this is an apartment so I doubt that he is going to spend a lot of money on hardware that he will have to leave behind at some point and I believe that he said the apartment requires him to use a licensed locksmith to change it anyway.
If the lock is really messed up the locksmith is just going to put a new one on anyway. That's why I suggested just doing it himself. I'd say the majority of home owners on this planet have 50 dollar locks from the local hardware store. I know I have 2 of them on my exterior doors. They're fine but i'm not in a high crime area.
Don't know about apartments. Didn't catch the part about him renting. I agree though it's probably better that he just call a good locksmith. If nothing else it takes the blame away from him if something goes wrong.
