With summer in full swing, many of us are enjoying more time in the garden, hosting barbecues, and opening up our homes to let in the fresh air. Patio doors—whether they’re sliding, French, or bi-fold—get a lot of use during the warmer months. But while they offer convenience and a great connection between indoor and outdoor living spaces, they can also present a potential weak point in your home’s security.
In this blog, we’ll explore how to check if your patio door locks are up to standard, what to look for when assessing their condition, and what steps you can take this summer to ensure your property remains secure.
Why Patio Doors Can Be a Security Risk
Patio doors are a common target for opportunistic burglars. Unlike your front or back door, which often have multiple locking points or more robust deadbolts, patio doors can sometimes feature outdated or poorly maintained locks. Common issues include:
- Worn or loose locking mechanisms
- Doors not closing flush with the frame
- Easily accessible handles
- Fragile or outdated glass panels
- Lack of anti-lift devices
With these issues in mind, it’s essential to carry out regular safety checks—especially in summer when your doors are open more frequently, and your home might be left unattended during holidays.
Summer Safety Checks for Patio Doors
Here’s a step-by-step guide to inspecting your patio door locks and ensuring they meet modern security standards:
Test the Lock Mechanism
Start by closing the patio door and locking it fully. The lock should engage smoothly, without needing excessive force. If you feel resistance, the mechanism may be worn, misaligned, or in need of lubrication.
What to do: Try using a silicone-based lubricant to ease the movement. If problems persist, the lock may need adjustment or replacement.
Check for Multipoint Locking Systems
Modern patio doors should have multipoint locking systems that engage at several points along the frame. These locks provide much greater protection than a single-point system.
What to do: If your doors only have a basic latch or a single lock, it’s worth upgrading to a more secure multipoint system.
Inspect the Door Alignment
Over time, patio doors—especially sliding or bi-fold styles—can become misaligned due to weather changes or general wear and tear. Misalignment puts pressure on the lock and makes it easier for burglars to force entry.
What to do: Ensure the door sits flush in the frame and glides smoothly along its track. A locksmith can easily adjust this if needed.
Examine the Lock Cylinder
Your lock cylinder should meet British Standard BS3621 or feature an anti-snap design, which is essential for preventing forced entry. Cheap euro cylinders are notoriously vulnerable to snapping, a common technique used by intruders.
What to do: Look for the BS3621 kite mark or consult a locksmith to assess the type of cylinder you have.
Assess the Handle Condition
Patio door handles are often overlooked, but loose or flimsy handles can compromise security. Handles should be sturdy, properly fixed, and not show signs of rust or corrosion.
What to do: Replace worn or damaged handles with high-quality, lockable versions.
Check for Anti-Lift Features
Sliding patio doors should have anti-lift devices to prevent the door from being lifted off its track.
Without these, a burglar could simply lift the door out of its frame—even if it’s locked.
What to do: Check whether an anti-lift bar or internal locking bolts are present. If not, these can usually be added at minimal cost.
Secure Your Garden Gates
Although not directly related to patio doors, it’s worth considering that many burglars access patio doors from the rear of the property. A weak or unsecured garden gate can give them easy access to your patio.
What to do: Ensure your garden gate is locked with a strong padlock or deadbolt to deter unauthorised entry.
When to Call a Locksmith
If your summer checks reveal any concerns—such as worn parts, outdated locks, or a lack of modern security features—it’s best to consult a professional locksmith. A qualified expert like RJ Parker Locksmiths can:
- Upgrade your patio door locks to modern BS3621 or anti-snap standards
- Adjust misaligned doors
- Install multipoint locking systems
- Provide advice on secure door and window hardware
- Offer emergency assistance if you’re locked out or need a fast repair
With summer being a peak time for home and garden activity, it’s also a time when many people unfortunately fall victim to opportunistic crime. Taking action now can help prevent security issues later.
Tips to Improve Patio Door Security Further
Alongside checking and upgrading your locks, consider these extra measures:
- Install window security film: Helps to strengthen glass against break-ins
- Use security bars or rods: For sliding doors, a metal bar placed in the track can physically prevent the door from sliding
- Keep valuables out of sight: Don’t leave bags, keys, or tech devices in clear view through the doors
- Close and lock doors when unattended: Even if you’re just popping next door or going inside for a minute
