Our wide range of safe and vault services include
Openings & Repairs
We specialize in opening all types of safes and vaults professionally, including burglary, jewelry, fire, document, wall, floor, gun, safety deposit, antique, electronic, dial or key. We can open safes that have been water damaged, vandalized, or broken— even when the competition has unsuccessfully tried to get it open. We will make the minimum hole possible to open the safe and repair it as if it was never drilled so the safe can continue to be used. Often we are able to recover lost combinations on many brand-name safes since we are registered safe technicians with many different manufacturers.
Combination Changes
Businesses often tell us that they have been using the same combination for as long as they can remember—even though many employees that no longer work there still know the combination! This severely impacts accountability if contents are stolen from the safe/vault with no signs of forced entry. It is not worth the risk or loss to keep an old combo that many people know. We can change combinations on electronic keypads and mechanical dials on almost all safes and vaults. Combinations on mechanical dials can slip over time which can lead to multiple dial attempts to successfully open the safe/vault. This can be corrected most of the time by having one of our technicians clean, reset and change the combination.
Emergency Service
We have multiple fully equipped service trucks to accommodate all of your emergency safe and vault security needs 24 hours a day. We know how important it is for your business to function with a properly operating secure safe and vault and we will make your emergency our priority.
GSA Government Safe & Vaults
Keystone Lock & Safe is a recognized GSA technician certified to work any GSA container & vault. We can service all Mosler, S&G and KABA XO locks as well as drill open and repair any containers as per the 809B Federal standard.
Preventative Maintenance
Many people don’t realize that safe/vault doors & locks have a lot of moving parts that require maintenance over time to ensure proper operation. Most lockouts are a result of broken locks due to age and lack of maintenance. We carry a large variety of safe parts such as handles, dials, keypads, hinge pins, battery packs, re-lockers and much more. Our typical preventative maintenance includes inspection of all movable parts for wear, inspection & cleaning of safe lock, replacing missing back panel screws, adjustment & lubrication, combination reset, changing batteries (where applicable) and complete tightening of the bolt work assembly.
Upgrades & Retrofits
Whether you’re looking to upgrade a mechanical dial to an electronic keypad or have your old safe repaired when parts are no longer available, we can explain all your available options. We stock a large selection of mechanical and electronic locks with options such as time delay, wrong try lockout, time lock, multi-user, dual custody and audit trails that can be installed or retrofitted on your existing safe or vault.
ATMs & Smart Safes
We can open, repair and service all types of ATMs and Smart Safes. We are factory trained in many different brands and can open anything from KABA Cencon to traditional style mechanical. We use the best opening methods & equipment available so all ATMs and Smart safes can be easily repaired after opening and put back into service.
Moving, Installations & Bolt downs
If you need a safe delivered, relocated or bolted down, we can accommodate all of your moving and installation needs. We also do fresh installations of wall and floor safes while taking all measures in keeping the workplace as clean and dust free as possible.
