🔐 Will a Smart Lock Work on My Door?

Read a bunch of articles and now itching to install a smart lock? But have you actually taken a good look at your door?

One of the most common questions we get is:

"Will this actually fit my door, or am I about to open a can of DIY worms?"

Spoiler: For most doors in Ireland and the UK — the answer is YES. Let’s break it down.

🚪 Common Door Types & Smart Lock Compatibility

Not all doors are created equal — but most are smart-lock friendly if you know what you’re working with. Below are the most common door types found in Irish homes, especially in areas like Dublin, Cork, and beyond.

Whether you’ve got a sleek modern entryway or a charming Georgian façade, here’s what you need to know before going smart.

🪵 Wooden Doors

Wooden doors are a classic sight across Ireland, particularly in older properties and heritage buildings — especially those elegant Georgian homes in Dublin. Valued for their natural beauty and solid construction, they’re commonly used in both interior and exterior applications.

✅ The good news? Most wooden doors with a standard Euro profile cylinder are smart lock-ready.

✔️ Easy to swap out

✔️ No major drilling

✔️ Perfect for smart locks like our sleek [P220] – with fingerprint, passcode, and app access

While composite doors are on the rise for their low maintenance and energy efficiency, wooden doors continue to shine for their traditional charm and aesthetic appeal — and yes, they play nicely with smart upgrades too.

🧰 DIY tip: 

Measure the cylinder from the center screw to each end (e.g. 35/35mm).

If it’s a Euro profile, you’re good to go.

🪟 uPVC Doors

uPVC (unplasticised polyvinyl chloride) doors are a popular choice in modern Irish homes — especially for their thermal performance, affordability, and low maintenance.

Often made by trusted brands like Munster Joinery, these doors are:

• Fully sheeted for insulation

• Lightweight yet sturdy

• Built with the environment in mind thanks to high recyclability

✅ These doors usually come with multipoint locking systems, meaning you lift the handle to engage multiple bolts.

Smart locks can absolutely work here — you just need the right kind:

• Smart lever handles that match your existing spindle setup

• Smart cylinders + adapter kits designed for multipoint systems

Tip: Send us a photo of your current handle and lock, and we’ll confirm compatibility — free of charge.

🧱 Composite Doors

Composite doors have surged in popularity for very good reasons — they combine the best of wood, uPVC, and insulation into one secure, stylish, and energy-efficient package. They’re also built with weather resistance in mind — a major win in Irish climates.

📦 These doors often come with enhanced security features baked right in, including:

• Reinforced cores

• Strong multipoint lock systems

• Weather-sealed outer shells

✅ Most composite doors use a standard Euro cylinder, meaning they’re compatible with many smart lock models.

While composite doors are popular for their hassle-free upkeep, smart locks only make them smarter — giving you app control, remote access, and fingerprint unlocking on top of the security features you already have.

🧩 Multipoint Lock Doors (Common in uPVC & Composite)

If your door requires lifting the handle to lock, congratulations — you’re in multipoint lock territory. Found in most uPVC and composite doors, this system engages multiple bolts at different points in the frame.

✅ It’s not a dealbreaker — you just need a lock designed for the job:

• Smart multipoint-ready lever handles

• Smart cylinders with compatible adapters

Don’t know what kind of lock you’ve got? Just take a photo and send it to us. We offer free consultations to match you with the right model.

🧊 Aluminium & Metal Doors

Aluminium and metal doors are gaining popularity in Ireland thanks to their sleek modern look, high durability, and excellent weather resistance — especially in coastal areas where exposure to wind and rain is a daily battle.

They’re often seen in contemporary homes, apartment buildings, and commercial properties for good reason: they’re tough, stylish, and low-maintenance.

✅ As long as your door uses a standard Euro profile cylinder and falls within the typical 35–60mm thickness range, you’re in luck — smart locks can absolutely work here.

While they may look high-tech or hard to modify, aluminium and steel doors are often just as smart-lock friendly as timber or composite doors. Our [Smart Cylinder 1A] is a great fit for these setups — waterproof, rust-resistant, and made for the Irish climate.

🛠️ Quick DIY Fit Test

Not sure if your door is ready to go smart? Don’t worry — you don’t need to be a locksmith or own fancy tools to figure it out. Here's how to check in under 2 minutes:

✅ Step-by-step:

1. Open your door and look at the side — where the latch is.

2. Find the cylinder screw — it’s usually level with the latch bolt.

3. Measure from the center of that screw to both ends of the cylinder.

   • Common sizes are 35/35mm, 30/50mm, etc.

   • This tells you if your cylinder is a standard Euro profile, which most smart locks are designed for.

4. Measure your door’s thickness (edge to edge).

   • Anything between 35mm–60mm works with most smart lock models.

   
   

🧰 Pro tip: If your current setup looks strange or non-standard, just take a photo and send it our way. We’ll tell you exactly what works — free of charge.

❓ What If My Door Isn’t Compatible?

Okay — let’s say you’ve done the measurements, looked at your lock, and… things just don’t line up. Maybe your door is older than your Wi-Fi. Or maybe it’s rocking a unique locking system that doesn’t fit the usual specs.

Good news: That doesn’t mean you’re locked out of going smart.

🔁 Workaround Options:

• Swap the cylinder: Many doors just need a compatible Euro profile cylinder — which we can help source and install.

• Upgrade your handle or backplate: If you’ve got a multipoint system or non-standard setup, we can recommend smart-ready hardware kits that work with your current door.
