Enhance your home security with stronger window locks

When most people think about securing their homes in Lincoln, their minds immediately go to door locks, alarms, and perhaps CCTV systems. But one key area that’s often overlooked is window locks.

In fact, windows can be one of the most vulnerable points of entry for burglars. Ensuring that your window locks are in top condition not only enhances the safety of your home but also gives you greater peace of mind.

At Secure Smart Locks, we regularly help homeowners across Lincoln tackle common window lock problems and upgrade their overall security. In this post, we’ll explore the frequent issues people encounter with window locks—such as jammed mechanisms and broken keys—offer some handy DIY solutions, and explain when it’s best to call in a professional.

Why window locks matter in Lincoln homes

Lincoln, with its charming blend of historic properties and modern housing estates, offers a diverse range of homes. However, this mix also means varying levels of security depending on the age and design of the property. Older sash windows, for instance, are particularly vulnerable without robust window locks, while modern uPVC windows still require regular maintenance to ensure the locking systems function effectively.

Window locks are not just a deterrent—they are a physical barrier that can prevent an opportunistic thief from gaining access. Additionally, many home insurance policies stipulate that all accessible windows must be fitted with key-operated window locks for the cover to remain valid.

Common window lock problems and DIY fixes

1. Jammed window locks

A jammed window lock can be incredibly frustrating, especially when you’re in a hurry or dealing with the unpredictable British weather. In many cases, the issue stems from dirt and debris build-up or misaligned components.

DIY tip:

• Start by cleaning around the window lock mechanism with a soft brush and mild soapy water.
• Apply a silicone-based lubricant (avoid oil-based products as they attract more dirt) into the keyhole and moving parts.
• Gently try to operate the lock several times to free up the mechanism.

If the window lock remains stuck after cleaning and lubrication, it may be due to internal damage or corrosion—this is where a locksmith should step in.

2. Broken keys in window locks

Snapping a key in a window lock is more common than you might think, especially with cheaper or older keys.

DIY tip:

• Use a pair of needle-nose pliers to carefully grip and pull out the broken piece if any part is sticking out.
• If the key is lodged deeper, you can try using a broken key extractor tool, which is available at most hardware stores.

When to call a professional:

If neither method works, or you’re worried about damaging the window lock further, it’s time to call Secure Smart Locks. Forcibly poking around with improvised tools can worsen the problem.

3. Loose or wobbly lock handles

Over time, window lock handles can become loose due to regular use.

DIY tip:

• Check for visible screws and tighten them using the appropriate screwdriver.
• If the handle is still wobbly, the internal spindle might be worn out, which will require replacement.

4. Key won’t turn in a window lock

This issue is often caused by misalignment or a worn key.

DIY tip:

• Try gently wiggling the key while applying light turning pressure—never force it.
• Use graphite powder as a dry lubricant in the keyway (avoid WD-40 as it can gum up window locks over time).

When to seek professional help

While many window lock issues in Lincoln homes can be handled with a bit of DIY, there are times when calling in a professional is the safest and most cost-effective option. Here’s when you should get expert help from Secure Smart Locks:

• Persistent jamming despite cleaning and lubrication
• Broken keys that can’t be removed easily
• Window locks that feel loose or insecure even after tightening
• Upgrading old window locks to meet modern insurance standards
• Suspicion of attempted break-in where locks or frames show damage
• Windows that won’t lock properly due to alignment problems

Remember, professional locksmiths have the right tools and experience to resolve the issue without risking further damage to your window locks, windows, or home.

Choosing the right locks

If you’re thinking about upgrading your security, it’s wise to consider the different types of window locks available:

• Sash locks – ideal for Lincoln’s many period properties
• Espagnolette locks – commonly found in modern uPVC windows
• Lockable window handles – provide an extra layer of protection
• Push-button locks – a convenient choice for internal windows
• Smart locks and sensors – an option if you’re enhancing your home security with smart technology

At Secure Smart Locks, we can assess your property and recommend the most suitable window locks, ensuring they comply with insurance requirements and offer maximum protection.

Boosting security beyond window locks

While robust window locks are a crucial part of your home’s defence, consider complementing them with additional security measures:

• Window restrictors to prevent windows from opening beyond a certain point (particularly useful for upstairs windows and child safety)
• Laminated security glass which is harder to break
• Window alarms and smart sensors to alert you to tampering or forced entry
