Start with the door
Choose hardware by the job of the door
A front entrance, a stockroom, a restroom and an emergency exit do different jobs, so they need different lock functions. Pick the function first, then hardware rated for how hard the door gets used. One lock for every door ends up wrong for half of them.
For busy doors we fit Grade 1 commercial levers, the heaviest-duty grade for cylindrical locks, and mortise locks where the door is prepared for them. We work on hardware from Schlage, Sargent, Corbin Russwin, Falcon, Arrow, Yale, Medeco and Mul-T-Lock, among others. Other lock and access brands we service include ASSA ABLOY, Allegion, dormakaba, Best, Kaba Ilco, Honeywell, Keyscan, Secura Key, SimonsVoss, American Lock, Brinks, Chicago Lock, CompX, Olympus Lock, ESP Hudsonlock, Illinois Lock, Ingersoll Rand, R.R. Brink, Segal, Strattec, Weslock, Maxtech, TSS and Tuff Stuff.
- Entrance or office: locks with a key from outside and a button or turn from inside.
- Storeroom: the outside lever is always locked and needs a key every time; the inside always lets you out.
- Restroom privacy: a thumb-turn or button inside, with an emergency release outside.
- Classroom: locked or unlocked from outside with a key, while the inside always lets you out.
- Exit door: an exit device lets people out with a push and controls who gets back in.
- Passage: no lock at all, for hallways and interior doors that only need to latch.
Keys and access
Rekeying, master keys and replacement
Rekeying, a master key system and new hardware solve different problems. Rekeying changes which key works a lock and keeps the hardware. It is the fast fix after a lost key or a staff change.
A master key system sets access levels. Each employee’s key opens their own areas, managers open their departments, and one key opens everything. When someone leaves, we rekey only the doors their key could open.
Replacement is for hardware that is worn, damaged, or the wrong function for the door.
Exits and closers
Exit devices, door closers and entry hardware
A door that sticks, will not latch or slams shut usually involves more than one part: the exit device or lock, the closer, the strike and how the door sits in its frame. We look at the whole opening before deciding what to adjust, repair or replace.
Device type, outside trim, door construction and how the door is used decide the options. Aluminum storefront doors, for example, need narrow-stile hardware that fits their thin frames. Exit and closer hardware we service includes Von Duprin, Detex, LCN and Adams Rite.
Access control
Electronic access control
Access control replaces keys with codes, cards or fobs, so you can add or remove a person without rekeying. Planning it means connecting the permissions you want with the actual door hardware, the power available and anything already installed.
Cabinets and safes
Cabinets, safes and interior access
A file cabinet lock and a building entrance are different jobs. For a lost cabinet key or a lock that will not turn, tell us the cabinet, the lock and who is authorized to open it. We also open, repair and install safes, change safe combinations and handle safe lockouts, including AMSEC, SentrySafe, Gardall and Honeywell safes.
By premises
Plan by how the building is used
These are the questions to work through for each kind of business. They are a planning guide, not a client list or a code ruling for your building.
Clinics and medical offices
A public entrance, staff-only rooms, storerooms for supplies and records, and privacy locks on restrooms. A master key system can keep each area on its own key.
Schools and training centers
Classroom-function locks, staff key levels and exit hardware on heavy-use doors. Access control helps when keys would otherwise change hands every term.
Shops and salons
Front-entry cylinders and levers, stockroom access, cabinet locks and restroom privacy locks.
Bars and restaurants
A public entrance, staff and storage access, restroom privacy, and exit devices and closers that stand up to constant traffic.
Offices and warehouses
Suite and storeroom locks, master key systems by department, and exit devices on rear and side doors.

I had to use this locksmith on Monday, which happened to be a holiday, and I couldn’t have been more impressed with the service! They responded incredibly quickly, were very professional and friendly, and had the job taken care of fast. Their customer service was excellent, especially considering it was a holiday. I really appreciated how easy and stress-free they made the whole situation. I would definitely recommend them to anyone needing a reliable and responsive locksmith!

Needed the house rekeyed this morning after an old roommate moved out and I didn't trust that every copy came back. Diamondback Lock and Key made it quick and easy, in and out in under an hour for four locks.

One of our front door locks failed completely on a Friday afternoon. Customers still coming in, employees trying to leave for the weekend. Not a good situation. If your business is in Chandler and you need commercial lock work done fast, Diamondback Lock and Key is who you want. Been in this building almost 14 years and dealt with a few locksmiths over that time. Nobody moved this quick. They had someone out before I even had time to start stressing about it. The tech knew exactly what he was looking at. Didn't try to sell me a full replacement when a repair was the right call. That matters when you're standing there watching the clock. Everything was solid by the time he left and we didn't lose more than an hour of business. For a commercial property owner thats everything.

Louis was amazing. I was dealing with an “incorrect key ID” error and a car that wouldn’t start. After programming the key, he wasn’t satisfied when the problem came back and strongly suggested I have the battery tested again. He was right. It turned out I had both a key issue and a failing battery. What stood out most was his customer service. I was stressed, overwhelmed, and having a rough day, and he treated me with kindness, patience, and a great attitude. He genuinely cared about solving the problem instead of just completing the job. Highly recommend!

Great service! They solved my problem the same day and sent a great guy who took only 30 minutes to cut and program my car key. I will recommend them anytime and will call them again for future projects.

Never used them before but Luis came out last week and got our business locks working again and I was so relieved it didn't take all day.

Our back door at the shop was a nightmare. You'd push it shut and it just wouldn't catch unless you basically kicked it into place. Eran from Diamondback Lock and Key in Chandler came out, took one look at it, and said the mechanism was dry. He hit it with graphite spray and the door closed smooth on the first try. Charged us a reasonable amount for the visit. Wish I'd called sooner.
Is rekeying the same as a master key system?
No. Rekeying changes which key opens a lock; a master key system sets different access levels across many locks.
A project can involve either or both. Rekeying fixes who has keys today; master keying decides who can open what from now on.
Do all our rooms need the same lever lock?
No. Entrances, storerooms, restrooms and classrooms each need a different lock function.
Match the function to the room first, then choose hardware rated for how hard that door gets used.
What affects the scope of commercial door work?
The door, the hardware on it, its condition, the lock function you need and any electronic equipment already fitted.
We look at the opening before confirming parts and price, and you get a clear estimate before work starts.
Will new hardware make our building code compliant?
We match hardware to each opening and tell you what we see, but code decisions for your building rest with your fire marshal or building official.
Fire-rated doors, exit routes and occupancy rules vary by building, so we do not make blanket compliance promises.
What warranty do you provide?
One month full warranty, and after that, a year warranty through the manufacturer, just for the parts.
