Your doors are the first line of defense for your home or business — but even the best locks and door closers wear down over time. Routine maintenance not only extends their lifespan but also prevents costly repairs, inconvenient malfunctions, and security risks.
At Locksmith On Demand, we help Newmarket property owners, managers, and businesses keep their locks and door closers operating smoothly year-round. Here are our expert maintenance tips to keep your security hardware in top shape.
Dirt, dust, and debris are the biggest enemies of smooth lock and door closer performance. Over time, buildup inside keyholes or hydraulic systems can cause friction, sticking, or grinding noises.
- Wipe locks, handles, and closer arms with a soft cloth every few weeks.
- Remove visible dust from the door closer’s piston or cover.
- Check the door frame and hinges for loose screws or corrosion.
💡Pro tip: Avoid using harsh cleaners — they can damage metal coatings. A simple damp cloth or mild soap is enough.
Both locks and door closers rely on internal springs and pins to operate smoothly. Without proper lubrication, they can wear down prematurely.
- Use a graphite-based or dry Teflon lubricant (never oil-based products like WD-40).
- Apply sparingly inside the keyhole every 6–12 months.
- Lightly lubricate exposed moving joints, pivot points, and arm connections.
- Never tamper with the hydraulic adjustment screws unless trained — incorrect adjustment can affect door speed or safety compliance.
If your door isn’t aligned properly, both the lock and closer will strain with every use. This often happens when doors expand or contract due to temperature or humidity changes.
- The door doesn’t close fully unless pushed.
- Lock bolt doesn’t line up with the strike plate.
- You hear scraping noises when closing the door.
A door closer is designed to control how quickly and securely a door shuts. Regular testing ensures it’s working safely and in compliance with building codes.
- Open the door fully and release it.
- The door should close smoothly and latch firmly without slamming.
- If it closes too fast, too slow, or doesn’t latch, adjustments may be needed.
⚙️Tip: Commercial doors should always close within 5–7 seconds from a 90° open position to meet accessibility and fire safety standards.
Over time, vibration and daily use can loosen screws in your locks, handles, or closer brackets. Loose hardware not only affects performance but can also lead to sudden failures.
- Tighten screws on the closer arm, bracket, and door frame.
- Check for cracks or wobbling in the mount points.
- Replace damaged screws immediately to prevent hinge misalignment.
The most common mistake property owners make? Ignoring small issues until they become expensive problems.
- Oil leaking from your door closer
- A squeaky or grinding sound when locking
- Keys sticking or turning roughly
- Difficulty closing or latching doors
Don’t wait — these are early signs of wear. A quick service call can prevent a full replacement later.
Even with regular cleaning and lubrication, professional maintenance ensures your locks and closers stay code-compliant and efficient.

- Inspect internal lock cylinders and closer valves
- Adjust spring tension and latch speed

Frequently Asked Questions (FAQs)
How often should I service my door closers?
At least once a year for commercial properties and every 18–24 months for residential doors — or sooner if you notice performance issues.
Why is oil leaking from my door closer?
Oil leaks indicate a damaged internal seal or cylinder. It’s best to replace the closer before it fails completely.
Can I adjust my door closer myself?
Only if you know what you’re doing — incorrect adjustment can cause damage or safety non-compliance. Always consult a locksmith.
How do I know when to replace a lock instead of repairing it?
If the lock is rusted, frequently jams, or the key turns loosely, replacement is usually the more secure option.
Do you handle large-scale commercial door closer maintenance?
