If you ever moved into a new place, lost your house keys or had to fire an angry employee, you’ve probably been in a situation where you considered changing your locks. Most people are not aware that instead of changing their locks, there is a much better, and often cheaper solution – re-keying them. In this article I’m going to explain what does it mean to “re-key” a lock, and more importantly – when should you rekey your locks rather than changing them. Why is this important you ask? Because it can save you quite a lot of money every year. Some locksmiths take advantage of the fact that people are not informed about the differences and instead of explaining the different options to the customer, they choose the more expensive option for them.
