How Long Will it Take a Locksmith to Rekey My Home?
It takes about 10-15 minutes to rekey a single lock, multiply that by the number of locks and you have got the time it should take to rekey your house. Locksmiths are paid by the hour at a rate between $10 and $25 dollars, relatively low for a specified professional, so in many respects it would be the wiser choice to hire a professional locksmith to rekey your house for you, who can supply the materials, and who won't mess up, instead of you taking the time to learn how to work a lock, going to buy the tools, and possibly breaking a lock, not to mention the time you save personally from saving an hour to possibly several hours of your time.
I heartily recommend to anyone who is reading this and in need of lock repair, please go have a professional locksmith do it for you. I see no reason, besides the possible joy of learning a new skill and becoming well versed in the intricate engineering of a lock to use your valuable time to perform what is essentially a specially type of manual labor.
