Sticky Locks? Don’t Get Locked Out! Understanding Corrosion & The Need for Regular Lock Servicing by Thanet Locksmiths
A stiff, sticky, or difficult-to-turn lock is more than just an annoyance – it’s a warning sign. Over time, and particularly in certain environments, the internal mechanisms of your locks can become compromised, leading to frustrating failures and, in the worst case, leaving you locked out or unable to secure your property.
Here at Thanet Locksmiths, we see first-hand how environmental factors impact the longevity and reliability of your locks. One of the primary culprits behind sticky locks, especially in coastal or urban areas like ours, is corrosion, specifically from salt.
The Silent Destroyer: Salt Corrosion
Salt, whether from the bracing sea air of Thanet’s coastline or the road grit applied to our main routes, is a highly corrosive agent for metals commonly used in locks (brass, steel, zinc alloys). Here’s how it causes havoc:
- Sea Spray & Coastal Air: Living in areas like Margate, Broadstairs, Ramsgate, or indeed anywhere across the Thanet district, means your property is constantly exposed to microscopic salt particles carried inland by the prevailing winds. These particles, combined with the often damp British air, create an electrolyte solution that rapidly accelerates the oxidation (rusting and corrosion) of metal components.
- Road Grit & Winter Maintenance: During colder months, main roads throughout Kent and beyond are frequently treated with de-icing salt. Vehicles kick up this salty slush and spray, which can settle on properties bordering these roads. This grit, often abrasive, combined with its corrosive properties, can be particularly damaging to external locks.
What happens inside the lock?
When salt corrosion sets in, it causes:
- Oxidation and Rust: Metals like steel will rust, forming flaky red/brown deposits. Brass and other alloys will develop verdigris or a dull, pitted surface.
- Build-up and Grime: These corrosive by-products, along with dust, dirt, and general atmospheric pollutants, create a thick, abrasive paste inside the lock cylinder and mechanism.
- Increased Friction: This paste and the roughened metal surfaces significantly increase friction, making it harder for the key to slide smoothly and for the internal pins and springs to move freely.
- Component Wear: The increased friction leads to accelerated wear and tear on the delicate internal components, eventually causing them to seize, bend, or break.
Why Your Location Matters: High-Risk Areas Across Thanet
While all locks benefit from maintenance, those in specific locations are under constant attack and require more frequent attention:
- Coastal Properties: If you’re overlooking the sea in Cliftonville, close to Ramsgate Harbour, or anywhere along our beautiful coastline, your locks are continually battling the corrosive salt-laden air. The closer to the shoreline, the greater the risk.
- Properties Near Main Roads/High Traffic Areas: The combination of de-icing salts in winter (e.g., A28, A253, A254) and increased airborne pollutants (dust, exhaust fumes) throughout the year creates a harsh environment for external locks.
- Properties in High Humidity Climates: Our temperate climate in the UK often means high humidity, which, even without salt, can accelerate general corrosion and encourage grime build-up.
The Solution: Professional Lock Servicing by Thanet Locksmiths – At Least Twice a Year!
For locks in high-risk areas across Thanet, a yearly service is simply not enough. We at Thanet Locksmiths strongly recommend that locks, particularly those on external doors and windows, are serviced at least twice a year. For very exposed locations, quarterly servicing might even be advisable.
What does professional lock servicing by Thanet Locksmiths involve?
A comprehensive lock service by our qualified locksmiths will typically include:
- Thorough Cleaning: Disassembly (where appropriate for the lock type) to remove accumulated dirt, dust, old grease, and corrosive deposits.
- Inspection: Examination of all internal components for signs of wear, damage, or impending failure.
- Lubrication: Application of appropriate, high-quality, non-greasy, and non-dirt-attracting lubricants specifically designed for lock mechanisms. These lubricants protect against corrosion and ensure smooth operation.
- Adjustment: Minor adjustments to ensure correct alignment and optimal performance of the lock and associated hardware (e.g., strike plates, handles).
- Functionality Test: Testing the lock’s smooth operation with the key from both sides.
Benefits of Regular Servicing:
- Extends Lock Lifespan: Protects your investment by preventing premature wear and corrosion.
- Ensures Reliability: Guarantees your locks operate smoothly when you need them to, avoiding frustrating sticky situations.
- Maintains Security: A well-maintained lock is a secure lock. Damaged internal mechanisms can compromise its integrity, leaving your home or business vulnerable.
- Prevents Costly Replacements: Addressing minor issues during servicing can prevent the need for full lock replacement down the line, saving you money.
- Peace of Mind: Knowing your property is securely locked and your locks are in optimal condition offers invaluable peace of mind.
