Locked out of your home or car? Emergency callouts run 24 hours a day, 7 days a week.
Access
Letting helpers in without handing out keys
When a relative, caregiver or home-health aide needs to get in, every extra key is one more you may not get back. A keypad deadbolt lets you give each person a code and delete it when they no longer need it.
Most keypad locks still have a key cylinder. We key it to match your other locks, so the house still works on one key if the batteries run down.

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.

We key the lock’s cylinder to match your other locks, so a backup key still works.
