Residential
House Lockout Service
Locked out of your house, condo or rental? Call (602) 388-1201. Emergency callouts run 24 hours a day, 7 days a week. We open the door for the people entitled to be inside, check the lock once you are in, and tell you whether it needs anything.

Right now
If you are locked out right now
- Call (602) 388-1201 and tell us the address, which door, and the kind of lock on it if you know.
- Ask whether anyone else has a key: someone in the household, a neighbor, or your landlord or property manager.
- If a child is inside and at risk, call 911.
- Do not force a window or pry the door. It can break glass, damage the frame and cost more than the lockout.
- Have your ID ready, or tell us if it is locked inside.
Who we let in
Proof that you can authorize entry
We open a home for the people entitled to be inside: the owner, a resident, or someone the owner has authorized. We confirm that, usually with a photo ID showing the address. If your ID is locked inside, we check it once the door is open, or ask for other proof such as a lease or mail in your name.
Renters: your landlord or property manager may have a key and a lockout policy, so it is worth a call. Getting you back in is one thing; rekeying or replacing a rental’s lock needs the owner’s authorization.
We open homes only for people entitled to be inside.
Getting in
How the door gets opened depends on the lock
The lock type and its condition decide the method. A knob or lever on its own, a locked deadbolt, a keypad or smart lock with dead batteries, a high-security cylinder, and a seized or broken lock each call for a different approach.
We start with the method least likely to damage the lock or the door, and many home locks open without harm. We cannot promise that for every lock: a high-security lock, a seized or broken lock, or a door with nothing that can be worked from outside may mean drilling a lock and replacing it. If it comes to that, we tell you and give you the price before we do it.
Once you are in
After the door is open
If the door or the lock was already damaged, by an earlier attempt to get in or a break-in, show us before we start so it is noted. Once you are inside, we check that the lock works properly with your key and tell you if it needs attention.
- Keys lost or stolen: rekey the locks so the missing keys stop working.
- The lock had to be drilled, or was already damaged: replace it, keyed to your other locks if you like.
- The lock failed and caused the lockout: repair or replace it.
- A keypad lock ran out of battery: fresh batteries, and a backup key kept outside the house.
- To avoid the next one: a spare key with someone you trust, or a keypad deadbolt.
Inside doors
Garage entry, side and interior doors
A locked garage entry door or side door is a lockout like any other. We also open locked bathroom, bedroom and closet doors; interior privacy locks are made with an emergency release, which is usually the gentlest way in.
Cost
What affects the price
You get the price before any work starts. It depends on:
- The type of lock and its security level
- Whether it opens without damage, or has to be drilled and replaced
- Any rekeying or new locks you want once you are in
- How many doors are locked

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.
What do I need to show to get back in?
Proof that you live there or can authorize entry, usually a photo ID with the address.
If your ID is inside, we check it once the door is open, or accept other proof such as a lease or mail in your name.
Will opening the door damage my lock?
Usually not, but we cannot promise that for every lock.
If a lock has to be drilled, we tell you and give you the price before we do it.
I rent. Can you let me in?
Yes, if you can show that you live there.
Rekeying or replacing the lock on a rental needs the owner’s authorization. Your landlord may also have a key.
Should I change the locks after a lockout?
Only if keys are lost or stolen, or the lock is damaged.
If your keys are missing, rekey so they stop working.
Do you handle lockouts at night?
Yes. Emergency callouts run 24 hours a day, 7 days a week.
Call (602) 388-1201 and we will tell you when a technician can reach you.
