Hopefully your landlord would not chose to be a dick about it, but if they want to they can in fact legally replace the locks and bill you for it without ever giving you an option to put the old locks back. I am telling you this only because that exact thing happened to me in an apt in years ago.

Also, be aware that it is in fact legal for you to lock any interier door securely even in a rental property. If the maintenance staff or landlord break in to that room or closet without just cause or prior notice you can have them charged with B&E. I know this because years ago I had a GF who thought either one of her roomates or the landlord was fucking with her shit and stealing things. When she called the cops, they came to do the report and they explained that even though it was a rental, she could legally lock an interior door. They then explained that if anyone including the landlord where to break that lock and come in, we could then have them charged with B&E. The only exception to that would be if they could demonstrate just cause in terms of emergency maintenance of some kind. This was in the US in NJ. If your outside the US it may be different rules I don't know.

good luck
unclebob Reviewed by unclebob on . changing the locks on my front door ok, going to be starting a little grow op in the bedroom closet. i'll just use the rest of the bedroom for storage of crap. anyway, i'm going to replace the doorknob on the bedroom door with one that locks, but i was thinking, as an extra layer of security, to change the lock on my front door. i rent, and maintenance has a master key to the building. it is a 3-story, about 100unit controlled-access building anyway, i'm pretty sure i'm not allowed to change my front door locks, but as Rating: 5
