Actually 3.5 stars but hey...first review of the new year and they treated my wife good...so...rounding up. Green Valley Lock & Safe is one of the few Locksmiths it seems with a brick & mortar you can take a lock in to have rekeyed. The only option for most other companies is a $75 service call plus rekey fee. We had a couple locks to rekey and didn't want to pay $100 to have someone come to the house. While they were considerably more expensive that the company we use in California, they were quick and efficient at rekeying. They charged extra to rekey one of the locks because we didn't have the key. I know it is a bit more effort to remove the pins manually but seriously, it is a five minute process to rekey a lock. I rekey all the Kwikset locks on our rentals but our houses have Schlage locks and I don't have a kit for them and i am told the tumbler removal process is a bit more difficult (at least for an amateur like me.) Anyway this is the company our old HOA uses to service the electronic locks on the clubhouse and pool. I have always found them responsive and professional for commercial and residential.
