Home Keyless Entry: Keypad and Smart Locks
We fit keypad deadbolts and smart locks to existing home doors, set up the codes with you, and key the backup cylinder to match your other keys where the lock has one. Tell us the door and the lock you have in mind, and we will tell you whether it fits before we book.

The choice
Keypad lock or connected smart lock
A keypad lock works on its own. Codes are entered and changed at the lock, it runs on batteries, and nothing connects to the internet. A connected smart lock adds an app and a link to your phone or home system over Bluetooth, Wi-Fi, Z-Wave or Zigbee. Depending on the model, that can mean remote locking, alerts and an access history.
Either one lets you stop handing out keys. A connected lock adds features, and also an app, updates and a network that have to keep working. If all you need is codes at the door, a keypad lock is the simpler choice.
- Keypad deadbolt: a code instead of a key, usually with a key cylinder as backup.
- Keypad lever: the same idea on a lever, for a side or garage entry door.
- Touchscreen lock: a glass keypad; some models have no key cylinder at all.
- Fingerprint lock: opens for enrolled fingerprints, with a code or key as backup.
- Connected smart lock: any of the above, plus an app and, depending on the setup, remote access.
Will it fit?
Check the door before the lock
Most keypad and smart deadbolts fit a standard deadbolt hole, but the details decide it: the hole size, the backset (how far the hole sits from the door edge), the door thickness, and room for the inside unit near the handle. Some smart locks replace only the inside half of an existing deadbolt; most replace the whole lock.
The bolt has to slide fully into the frame without anyone pushing or lifting the door. A motorized bolt strains against a misaligned strike, drains its batteries and jams, so if the bolt binds we adjust the strike or the door first.
Arizona heat and monsoon dust are hard on exterior locks, and a keypad on a west-facing door gets hot. Check the lock’s rated operating temperature before buying one for a sun-facing door.
Backup entry
Batteries and a backup way in
Battery-powered locks warn you before the batteries run out, usually with a light, a beep or an app alert. Change them when the warning starts.
Choose a lock with a backup. Most keep a key cylinder; some cylinder-free models have terminals for a battery jump-start instead. Keep the backup key somewhere you can reach from outside, such as with a neighbor or family member you trust, not inside the house.
Where the lock has a key cylinder, we can usually key it to match your other door keys.
Codes and access
Codes, users and who gets in
Give each person their own code instead of sharing one. When a cleaner, dog walker or contractor no longer needs access, delete their code and nobody else has to change anything. Many locks also allow scheduled or temporary codes.
The homeowner, or a tenant with the owner’s permission, should hold the programming or admin code. Moved into a home with a keypad or smart lock already on the door? Reset it to factory settings, set new codes, remove the previous owner from any app, and rekey the backup cylinder.
We set up the codes with you before we leave, so you know how to add and delete users yourself.
Apps and smart homes
Apps, voice assistants and home systems
Whether a lock works with your phone, voice assistant, alarm or home hub depends on the exact model and your setup: which app it uses, whether it needs a hub or bridge, and which systems it supports. Check the maker’s compatibility list for that model before buying.
We fit the lock and get it working at the door. Wi-Fi coverage at the door and app account setup sit outside the lock itself, so we do not promise that a lock will work with every app, network or smart-home platform.
Keypad and smart lock brands we work with include Schlage, Kwikset, Yale, Nest x Yale, August, Ultraloq, Lockly, Level Lock, Eufy, Alarm Lock, Kaba and Codelocks.
What to expect
What to tell us, and what happens next
We confirm the lock fits before booking and give you a clear estimate before any work starts. The technician fits and aligns the lock, sets it up with you, and checks that it locks and unlocks from both sides with the door closed.
- Which door, and whether it has a deadbolt now
- Photos of both sides of the lock and of the door edge
- The lock you have bought or are considering, or that you would like options
- Whether the backup cylinder should match your other keys
- For a rental, the owner’s permission
Cost
What affects the price
You get the price before any work starts. It depends on:
- The lock itself: keypad or connected, and whether you supply it
- Whether the door needs drilling, a larger hole or new strike work
- Any door or strike adjustment so the bolt runs freely
- Keying the backup cylinder to match your other locks
- How many doors, and whether a matching handle or lever is changed at the same time

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.
Can a keypad lock go on my existing door?
Usually, yes, if the door has a standard deadbolt hole and the bolt slides freely.
Hole size, backset, door thickness and room for the inside unit decide it. Send photos and we will confirm before booking.
What happens when the batteries die?
The lock warns you first; if they do run out, you use the backup.
That is a key cylinder on most models, or a battery jump-start on some cylinder-free ones. Pick a lock with a backup.
Can my smart lock use the same key as my other doors?
Yes, if it has a key cylinder with a compatible keyway.
We key it to match where the cylinder allows. Kwikset and Schlage keys are not interchangeable.
Will it work with my phone, voice assistant or alarm?
It depends on the exact lock model and your setup.
Check the maker’s compatibility list for that model. We do not promise every app or platform.
What should I do with a keypad lock in a home I just bought?
Reset it and set new codes.
Reset it to factory settings, remove the previous owner from any app, and rekey the backup cylinder.
