Grand Master Key Systems in Commerce: What's Really Involved
Rekeying is one of the smartest, most cost-effective security moves a homeowner or business owner can make. Instead of buying and installing brand-new locks, we simply change the internal pin configuration of your existing cylinders so that a new key works and every old key is instantly retired.
It's fast, affordable, and it puts you back in control of exactly who can open your doors — which matters more than most people realize, because you can never really be sure how many copies of an old key are out there in the hands of previous owners, tenants, contractors, or anyone they handed a key to.
