If you’ve just moved into a new office or business space, any locksmith will recommend that you rekey the locks for your security and peace of mind. It’s not a good idea to take any chances; multiple keys could have never been returned or been lost. When your commercial door locks are rekeyed, the old lock pins are switched out with new ones. Especially in a commercial building, rekeying is a great way to secure your property and is cheaper than replacing the locks.
