Why Your House Key No Longer Works: Common Causes and Fixes in Phoenix
There’s nothing more frustrating than standing at your front door, turning your key—and nothing happens. It’s even worse when you’re locked out during a Phoenix heatwave or trying to rush inside with groceries in hand.
At Affordable Security Locksmith And Alarm, we help Phoenix homeowners every day with key and lock problems just like this. If your house key suddenly stops working, check out our residential locksmith services or explore the common causes and quick fixes below.
🔍 Common Reasons Your Key Isn’t Working
1. Worn-Out Key
Over time, keys wear down, especially if they’re frequently used or poorly cut. A worn key might no longer align properly with the lock’s internal pins.
Fix:
We can cut a new key from the original code or rekey your lock for a fresh match.
2. Worn or Damaged Lock Cylinder
Phoenix’s intense sun and dust can cause internal parts in your lock to wear, dry out, or seize up—especially if it’s never been cleaned or lubricated.
Fix:
Lubricate with a dry graphite or silicone spray. If that fails, it’s time to repair or replace the lock cylinder.
3. Key Isn’t Fully Inserted
This might sound basic, but if the lock is misaligned or filled with debris, your key might not be seating properly inside.
Fix:
Try inserting the key gently and slowly. If it feels blocked, do not force it—you may bend or break the key. Call a pro for a safe inspection.
4. The Key Turns, But the Door Won’t Unlock
This usually means the tailpiece inside the lock is broken or misaligned—often caused by wear or cheap hardware.
Fix:
We’ll inspect the lock’s internal components and either tighten, repair, or replace the faulty part.
5. Weather Effects in Phoenix
Extreme heat causes locks to expand, while dust can gum up the internal pins. Both of these are common issues in Arizona.
Fix:
Regular maintenance helps. We recommend lubricating your locks 1–2 times a year and scheduling a professional inspection if your key sticks frequently.
6. Incorrect Copy or Duplicate Key
A poorly cut duplicate can have just enough variance to prevent it from working properly, even if it “almost” fits.
Fix:
We can cut a precision key based on your lock’s original specs—much more accurate than hardware store copies.
