September is the perfect time to walk around your home and take a closer look at your doors, locks, and entry points before winter arrives. Colder temperatures, moisture, and changes in humidity can affect doors and hardware, turning a minor issue into an annoying problem when the weather gets harsher.
A seasonal check doesn’t have to be complicated. A few minutes spent testing the important parts of your home can reveal problems that are easy to overlook during everyday life.

1. Test Every Exterior Lock
Start with the front, back, side, basement, and garage doors. Insert each key and turn it slowly. The key should move without excessive pressure, grinding, or repeated attempts.
If a lock has started sticking, don’t wait for it to become completely unusable. Difficulty turning a key can point to wear, alignment problems, or an issue inside the locking mechanism.
2. Check Your Deadbolts and Latches
Open the door and operate the deadbolt. Then close the door and test it again.
Pay attention to any difference. If the deadbolt moves freely with the door open but becomes difficult to extend when the door is closed, the door or frame may have shifted enough to affect alignment.
Also check whether the latch catches properly when the door closes.
3. Don’t Ignore Your Garage Entry
Garage doors and the doors connecting your garage to your home are easy to forget during a security check. Examine the lock, handle, deadbolt, and surrounding hardware.
A garage can provide access to the rest of the house, so its entry points deserve the same attention as your main entrance.
4. Give Your Smart Locks a Pre-Winter Check
Smart locks should also be included in your seasonal routine.
Check the battery level, test the keypad or fingerprint reader, confirm that the mobile app connects properly, and make sure you know how to use the backup-entry option.
Replacing batteries before they become critically low can help prevent an unpleasant surprise later.
5. Look at Your Door Hardware
Loose screws, worn handles, damaged strike plates, and shifting hinges can affect the way a locking system works.
Close each exterior door and check whether it sits properly within the frame. A door that rubs, moves excessively, or requires force to close may eventually create problems for the lock.
6. Review Who Has Your Keys
September is also a useful time to think about key control.
Over the years, spare keys can end up with family members, former roommates, contractors, neighbors, cleaners, tenants, or other people who may no longer need access.
If you’re unsure who still has a copy of your house key, consider having the lock rekeyed or replaced. You don’t necessarily need to replace every piece of hardware to regain control over access.
7. Inspect Less-Used Doors
The door you rarely use may be the one most likely to surprise you.
Try every exterior entry at least once. Check basement doors, storage areas, sheds, side entrances, and other access points for sticking, corrosion, damaged keys, or loose hardware.
8. Pay Attention to Weather-Related Door Movement
Temperature and humidity can cause some doors and frames to expand, contract, or shift slightly. Even a small change can put pressure on the latch or deadbolt.
If you notice that a door suddenly needs to be pushed, pulled, or lifted before the lock works, it’s worth having the issue examined rather than forcing the hardware.
When Should You Call a Locksmith?
Not every lock problem requires immediate replacement. Sometimes the issue involves alignment, a worn component, the cylinder, or the surrounding door hardware.
A locksmith can identify the source of the problem and determine whether adjustment, repair, rekeying, or new hardware makes the most sense.
