a friend of mine had a tennant living in the basement of his house. the tennant moved out on good terms, but my friend wants to change the locks anyway. he has 4 doors for a combined 3 deadbolts and 4 door handle locks. Door handle lock: originally he was thinking of going to Home Depot and just buying 7 new locks and having the Home Depot locksmith key them all the same. i suggested hiring a locksmith and have him re-key everything to save time + effort. What would you do ATOT?
