How to Choose the Perfect Digital Lock for Your Door — A Simple Guide from Studio 79

Why choosing a digital lock can be tricky

Ever walked into a hardware store or scrolled through online listings only to be flooded with terms like backset, cross-bore, and thick-door kit?
Digital locks are amazing upgrades — keyless entry, PIN codes, fingerprints, even app control — but they only work perfectly if they fit your door.

And here’s the truth: most returns and installation headaches come from not measuring before buying. This guide will make sure you measure once, buy once, and enjoy your new lock without extra drilling, awkward gaps, or buying “extension kits” you didn’t plan for.

Hey there! At Studio 79, we know that choosing the right digital or smart lock can feel tricky — but it doesn’t have to be. We’re proud distributors of all premium digital locks, and we want to help you pick the perfect one for your door quickly and confidently.

To make things easy, here’s a simple checklist you can follow to find out exactly what kind of lock will fit your door best.

Step 1: Measure Your Door Thickness (in mm)

Most digital locks fit doors within a certain thickness range, so start by measuring your door’s thickness using a tape measure or ruler.
Typical door thicknesses range from 35mm up to 110mm — knowing this helps us suggest locks that fit snugly without damaging your door.

Step 2: Measure Your Door Stile Width (in mm)

The stile is the vertical edge of your door where the lock is installed. Measure the width of this stile (usually between 90mm to 120mm). Some digital locks require a minimum stile width to fit properly.

Step 3: Identify Your Door Type — Single or Double?

Is your door a single door or a double door setup? This matters because some locks are designed specifically for single doors, while others support double doors or even sliding doors.

Step 4: Know Your Door Material

Doors come in various materials, such as:

• Wood
• Metal
• Glass with Wood frame
• Other materials

The lock installation method may differ depending on the material, so it’s important to specify this when choosing your lock.

Step 5: Check the Door Opening Direction

Is your door opening to the left or right? Does it open inward or outward? This determines the lock orientation and the side where the keypad or handle will be placed.

Step 6: Do You Have an Existing Lock?

If your door already has a lock, knowing its type helps us understand if the digital lock can replace it directly or if extra modifications are needed. Is it a deadbolt, mortise lock, or a rim lock? Let us know!

Why Does All This Matter?

Each digital lock model has specific installation requirements. By knowing these 6 key details about your door, Studio 79’s expert team can recommend the best premium smart lock that fits perfectly, works smoothly, and secures your home or business.

Frequently Asked Questions (FAQs)

Q1: Can I install a digital lock myself?
While some locks are easy to install, we recommend professional installation to ensure proper fit and maximum security.

Q2: What if my door thickness is outside the usual range?
No worries! We have locks designed for a variety of thicknesses. Just share your exact measurements, and we’ll help you find the right fit.

Q3: Do digital locks work on metal doors?
Yes, many premium digital locks are compatible with metal doors, but installation may require special tools or plates.

Q4: How do I know if my door opens left or right?
Stand outside facing your door. If the hinges are on the left, it’s a left-opening door; if on the right, it’s a right-opening door.

Q5: Can I keep my existing lock along with the digital lock?
In some cases, yes. We can suggest digital locks that come with additional security features or work alongside your existing setup.
