I can buy the hardware in hardware store, why do I need Locksmith?
Products typically sold in home stores are residential quality at best, at worst the shelves are stacked with low end products meant to increase profits for the manufacturer and the retailer. High quality goods offer characteristics such as, pick and drill resistance, access control options, protection against the unauthorized duplication of keys. The question you have to ask is what is your time really worth?
Moved to new property My landlord gave me keys, why do I need new one?
It's your stuff! When was the last time the locks were changed? If you don't know the answer then you and your company are potentially at risk. Some property management companies in an effort to save money simply swap the locks from one unit to another and have a brand new set of keys made. A previous tenant with some time to kill could simply try his key in each door in the complex until he finds one that works.
