Don’t Buy a Digital Lock Without Reading Our Guide!

Many people are buying digital locks for their homes, offices, or even factories. We all want the best digital lock, but most of us overlook the important factors when making a purchase. Most buyers assume all digital locks are the same, offering just fingerprint access, RFID cards, and PIN codes. But there’s much more to consider.

In this blog, we’ll break down what you should look for before buying a digital lock — from compatibility and features to safety, usage needs, and reliability. Understanding what works for you (and what doesn’t) will help you choose the right digital lock that truly meets your needs. So, keep reading — this guide will help you make the best and most satisfying choice.

1. Compatibility: Will It Fit Your Door?

Before you fall for sleek designs and smart features, check whether the lock is compatible with your door.

Door Thickness & Handle Type

Start by measuring your door’s thickness. Most locks fit standard-sized doors, but it’s always best to confirm. Also, check your handle type—some locks have levers or push-pull handles.

Existing Hardware

Some digital locks are designed to retrofit over existing deadbolts. Others are full replacements that require professional installation. Know which one suits your setup.

Replacing your digital lock or installing one on a new door? Professional installation is always recommended for the best fit, safety, and long-term reliability.

Smart Home Integration

If you’re using smart systems like Alexa, Google Home, or Apple HomeKit, ensure the lock supports them for voice control or automation.

Pro Tip: Planning to order your digital lock online? Don’t forget to check the specifications; most websites list the compatible door thickness, and it’s an important detail you shouldn’t miss.

2. Features: Beyond Fingerprints and PIN Codes

Modern digital locks offer much more than just unlocking the door using a PIN code or fingerprint.

Types of Digital Locks & Must-Have Features

Not all digital locks are the same. While most offer basic unlocking options, advanced models are packed with smart features that enhance both security and convenience.

Common Lock Types:

• RFID Card Access
• Fingerprint Recognition
• PIN/Password Entry
• Mechanical Key Backup

These are the standard access methods found in most digital locks — ideal for everyday use by families, tenants, or office teams.

Advanced Features to Look For:

• Face Recognition: Unlock the door with just a glance — secure and hands-free.
• Dual Unlocking / Synchronization: Open both your main door and gate together using one action.
• Dual Authentication: Adds extra security by requiring two verification methods (e.g., PIN + fingerprint).
• Video Intercom: See and speak to visitors before unlocking the door.
• Auto-Lock Timers: Automatically lock to prevent doors from being left open.
• Real-Time Activity Logs: Track who accessed the door and when — perfect for monitoring kids or guests.
• Temporary Access Codes: Share limited-time PINs with visitors, cleaners, or delivery personnel.
• Fire-Rated Models: fire-rated digital lock certified for fire Resistance — an essential feature for HDB, BTO, and condo units.
• Tamper Alarms: Alerts you instantly if someone attempts forced entry or tampers with the lock.
• Encrypted Communication: Ensures your smart lock data is protected from hacking or cloning attempts.

Tip: Always choose locks with strong encryption and safety certifications to protect your property from digital and physical threats.

3. Usage Needs: Choose Based on Your Lifestyle

Your daily routines and environment should shape the lock you choose.

Home vs. Office Use

Offices need support for many users, durable hardware, and access logs. Homes may prioritize ease of use and fewer access methods.

Temporary Access

If you’re hosting on Airbnb or often have service workers over, opt for locks with one-time or time-based access codes.

Accessibility

Consider models that are user-friendly for kids, elderly family members, or people with mobility needs.

4. Reliability: Built to Last

Your lock should be ready for the long run, not just day one.

Battery Life

Most digital locks use AA batteries, AAA batteries, and Li-ion batteries, which can last 4–12 months. Look for models with battery alerts and backup power options like USB-C.

Weather Resistance

If the lock is exposed to weather (e.g., on gates or outdoor doors), make sure it’s rated for rain and heat with a minimum of IP65 protection.

Build Quality

Choose locks made from corrosion-resistant materials like stainless steel or zinc alloy.

Pro Tip: Reputable brands often offer 1–3 year warranties. That peace of mind is worth it.

These are the key things you should know before buying a digital lock. One important point—if you have a fire-rated door, make sure to install a fire-rated digital lock. Always check the product description and brand details carefully, as different locks are made for different types of doors, such as glass doors, bedroom doors, and gates.
