Patio & Sliding Door Locks
Why Sliding Doors Are a Security Weak Spot
Many homeowners focus on locking the front door before leaving the house but completely forget about the sliding door at the back. The problem is that burglars know this—and they know that most sliding doors can be broken into within seconds.
Common Ways Burglars Break In Through Sliding Doors
- Forcing the latch – The standard locks that come with most sliding doors aren’t very strong. A simple push with a crowbar or even a firm shove can pop the latch open.
- Lifting the door off the track – If your door is older, it may not have anti-lift protection, meaning a burglar can literally lift it out of the frame and step inside.
- Smashing the glass – While breaking glass is noisy, burglars sometimes take the risk—especially if they know no one is home.
- Walking right in – Many people forget to lock their sliding doors, making it effortless for an intruder to enter.
A Real-Life Example (Yes, This Happens More Often Than You Think!)
I once had a client who went on holiday for two weeks. They double-locked the front door, installed a camera, and even left the lights on a timer. But when they returned, their home had been ransacked. How? The burglars had simply lifted the sliding door off the track and walked right in. No forced entry, no alarms—just an open invitation.
How to Properly Secure Your Sliding Door
The good news? You can easily reinforce your sliding door with a few smart upgrades. Here’s what you need to do:
1. Upgrade the Locking Mechanism
If your sliding door still has the factory-installed latch, it’s time to replace it.
- Install a double-bolt lock, which secures the door at the top and bottom instead of just at one point.
- Consider a smart lock, so you can lock and unlock your door remotely with an app.
➡️ Bonus tip: Most locksmiths can recommend British Standard (BS3621) locks, which meet high-security standards in the UK.
2. Install a Security Bar or Rod
A simple but highly effective trick: place a solid rod (like a metal bar or a wooden dowel) in the track of your sliding door.
Why does this work? Even if someone manages to unlock the door, they can’t slide it open because the rod physically blocks it.
3. Prevent the Door from Being Lifted Off the Track
Older sliding doors can easily be lifted out of the frame, but there’s an easy fix:
- Anti-lift devices – These are brackets or screws installed at the top of the frame, making it impossible to lift the door.
- Adding extra rollers – If your door sits loosely on the track, replacing worn-out rollers can improve security.
4. Reinforce the Glass
Since sliding doors have large glass panels, you also need to think about shatter protection.
- Apply security film – This makes glass harder to break, similar to how a car’s windshield cracks but doesn’t shatter.
- Upgrade to laminated or tempered glass – These are much stronger than regular glass.
- Install window sensors – These trigger an alarm if the glass is broken.
5. Use Motion Sensor Lights & Cameras
Burglars hate well-lit areas. Installing motion-activated lights near your sliding door can scare off potential intruders.
For even better protection, consider a CCTV camera positioned near your sliding door. Many smart security cameras send real-time alerts to your phone if they detect movement.
6. Smart Security Features
If you’re already using smart home devices, why not integrate your sliding door into your security system?
- Contact sensors – These notify you when the door is opened.
- Smart locks – Lock or unlock the door remotely.
- Integrated alarms – If someone tampers with the door, an alarm sounds.
Additional Safety Measures for Sliding Doors
✔ Always Keep It Locked!
You’d be surprised how often burglars don’t even need to break in—homeowners simply forget to lock the door.
A good habit: Before bed or leaving the house, double-check that it’s locked.
✔ Maintain the Door’s Track & Rollers
A dirty or damaged sliding door track can prevent your lock from engaging properly. Keep it clean, and replace any worn-out rollers to keep the door secure in its frame.
✔ Install a Secondary Security System
A basic sliding door alarm is an inexpensive way to boost security. These devices sound a loud siren if the door is forced open, scaring off intruders.
