I’m Josh, and after a decade turning wrenches on locks across AZ, I’ll tell you straight: storm door lock installation trips up more homeowners than almost any other DIY project. Not because it’s complicated — but because people buy the wrong hardware before they understand what they’re working with. If you’re in Tempe, AZ and you’re about to head to the hardware store, give me five minutes first.
Storm Door Locks Aren’t One-Size-Fits-All
Storm doors come in a surprising range of frame thicknesses, handle bore patterns, and door-face depths. A lock that fits a standard Larson door won’t necessarily drop into a Andersen or a no-name builder-grade unit. Before you buy anything, measure three things:
- Frame thickness — most storm door frames run 1″ to 1¾”; your lock’s spindle must match.
- Bore hole diameter — typically 1-⅜” or 1-½”; wrong size means drilling, which voids some warranties.
- Backset — the distance from the door edge to the center of the bore hole, usually 2-⅜” or 2-¾”.
Write those numbers down. Seriously — take a photo of your existing hardware, tape measure included. It’ll save you a return trip to the store and 45 minutes of frustration in your driveway while the AZ sun is doing its thing.
Should You Add a Storm Door Deadbolt?
A lot of homeowners ask us about storm door deadbolt installation as an extra security layer. Honest answer: it helps, but only when your primary entry door is also properly secured. A storm door deadbolt slows someone down and adds a visible deterrent — both real benefits. But if the deadbolt on your main door is worn, improperly installed, or keyed to a lock that an ex-tenant or former contractor still has a copy of, the storm door is just theater.
A storm door lock is a first line, not a finish line. Pair it with a properly rekeyed primary deadbolt and you’ve actually changed something.
If you’re dealing with an access concern — a lease that ended, a relationship that changed, anyone who might still have a key — our team handles residential rekeying the same day. We serve homeowners throughout Tempe, AZ and across the valley, from Scottsdale to Chandler to Gilbert.
storm door lock installation: DIY vs. Calling a Pro
Some installs genuinely are DIY-friendly. Others aren’t. Here’s a quick comparison to help you decide before you commit:
| Situation | DIY Friendly? | Notes |
|---|---|---|
| Replacing an identical lock, same bore | Yes | Straightforward swap; follow manufacturer instructions |
| Adding a lock where none existed | Sometimes | Requires drilling; one wrong cut and the frame is damaged |
| Storm door deadbolt on an aluminum frame | Caution | Aluminum cracks under improper torque — easy to ruin the door |
| Keying storm door to match primary lock | No | Requires a locksmith with the right pinning tools |
Keying your storm door lock to match your front door deadbolt — so one key operates both — is one of the most requested services we do. It’s not a hardware-store solution. It needs a professional with the right pinning kit and the time to do it correctly. Check out our full locksmith services to see everything we handle for residential customers.
A Word About Tempe, AZ Homes Specifically
Homes near Mill Avenue, the neighborhoods around Arizona State University, and the older ranch-style builds off Rural Road tend to have non-standard door configurations — mix of original hardware from the ’70s and ’80s with modern replacements layered on top. If your home fits that profile, don’t assume a standard kit will work. Measure twice, or call us first and we’ll tell you what you actually need before you spend a dollar on hardware.
We also see a lot of questions from homeowners near Chandler Boulevard and the Tempe Marketplace corridor — high-traffic areas where visibility makes people feel safer, but a poorly fitted storm door lock can give false confidence. Real security is in the details of the install, not just the presence of hardware.
For more on layered entry security — including how commercial properties approach multi-point access — the Associated Locksmiths of America consumer resource page is worth a read. And if you’re curious how those same principles scale up, our post on what’s different about large facility security gives you a solid picture.
Bottom line: don’t let the hardware purchase be the last thought. Whether it’s a simple swap or a full add lock to storm door project that requires drilling and keying, the outcome depends on preparation. When you’re ready to have it done right — or just want a second opinion before you start — call Sundial Locksmith at (480) 525-7778. We’ve been doing this since 2009, and we’ll give you a straight answer, not a sales pitch.
