Everyone has faced the annoyance of a stubborn lock at one point or another. A key that refuses to turn or gets stuck can be frustrating. But what causes this? And how can you prevent it?
Understanding the Lock Mechanism
Before delving into the reasons, it’s crucial to understand the basic lock mechanism:
- Key Pins: These are tiny pins that fit your key’s unique cuts.
- Driver Pins: Sit above the key pins and are pushed up when the correct key is inserted.
- Shear Line: The gap where the key pins and driver pins meet. When aligned perfectly, the key turns.
Top Reasons Why Keys Get Stuck
1. Dirt and Grime Accumulation
- Over time, dirt and grime build up inside the lock.
- They can obstruct the pins, preventing smooth key movement.
2. Misaligned Door Latch
- The door latch and strike plate might be misaligned.
- This misalignment creates resistance when turning the key.
3. Worn Out Keys
- Regular wear and tear can alter a key’s shape.
- A worn-out key might not align with the pins correctly.
4. Damaged Lock
- Internal lock components can wear out or break.
- Damaged components hinder the key’s operation.
5. Temperature Changes
- Extreme cold can cause metal contraction, affecting the lock’s mechanism.
- This can make the key harder to turn or even get stuck.

Preventing Sticky Situations

- Lubricate the lock mechanism once a year.
Replace Old Keys
- If your key is bent or worn out, get a replacement.
- Keep spare keys in a safe place.
Seek Professional Help
- If you’re unsure about the lock’s condition, consult a professional.
- Don’t force a stuck key; it might break inside the lock.
Weather and Your Locks
Effect of Humidity and Rain
It’s not only temperature extremes that can impact your locks. Humidity and prolonged rainy seasons can also affect the internal mechanisms of a lock. Moisture can seep into the tiniest of spaces, leading to:
- Rust Formation: Over time, accumulated moisture can lead to rust, making it hard for keys to turn smoothly.
- Swollen Door Frames: Increased humidity can cause wooden door frames to swell, misaligning the latch and strike plate.
How to Mitigate Moisture Damage
- Use rust-resistant locks for external doors.
- Ensure proper sealing around doors to prevent moisture seepage.
- Consider investing in weather-resistant locks if you live in areas with high humidity or frequent rainfall.
We often get duplicate keys made for various reasons, be it for family members or as a spare. However, not all duplicate keys are perfect replicas of the original. Minor discrepancies in the cuts or grooves can result in:
- Imperfect Fit: The duplicate key may not align perfectly with the pins.
- Increased Wear and Tear: Using such keys regularly can lead to faster degradation of the lock.
Ensuring Quality Duplicates
- Always get duplicates made from reputable locksmiths.
- Compare the original and duplicate side by side to check for discrepancies.
- If the duplicate key feels tight or rough, get it checked or replaced.
The Importance of Using the Right Tools
While many DIY enthusiasts may be tempted to tackle stuck keys or locks on their own, using inappropriate tools can lead to more harm than good. Issues that can arise include:
- Damaged Lock Internals: Using too much force can damage the pins or other delicate parts.
- Scratched or Damaged Exteriors: The aesthetic appeal of your door can be compromised.
