Digital Lock Installation on Existing Doors in Singapore

Are you considering switching to a digital lock but unsure if it can be installed on your current door? The good news is—you don’t always need a brand-new door to enjoy the benefits of a smart digital lock. Many models today are designed to work with existing HDB, BTO, condo or landed property doors in Singapore. Let’s explore how digital lock installation on existing doors works, what to check for, and why professional help makes a difference.

Can Digital Locks Be Installed on Existing Doors?

Yes, in most cases, digital locks can be installed on existing main doors—whether wooden, laminate, or even fire-rated. However, before making the switch, a few compatibility factors need to be checked:

• Door thickness – Most digital locks require a thickness between 35–70mm.
• Lock cut-out compatibility – Your current lock hole and handle position should align with the digital lock’s template. If not, adjustments can be made by a professional.
• Door condition – The door must not be warped, damaged, or misaligned, as these could affect installation and lock performance.
• Door and gate gap – A minimum gap of 85mm is required between the door and gate for smooth installation and proper lock operation.

Not every door is instantly ready for a digital upgrade, but with a proper assessment, most can be adapted.

Why Consult a Professional?

While some may attempt a DIY installation, digital locks are precision devices that work best when installed correctly. A professional locksmith or security specialist will:

• Inspect your door for compatibility
• Recommend suitable digital lock models (Hafele, Xeno, Aqara, and more)
• Ensure correct wiring and alignment
• Test all unlocking methods (fingerprint, PIN code, RFID, mobile app)
• Guide you through usage and maintenance

This ensures your lock functions smoothly and provides the maximum security it was designed for.

HDB Door Rules You Should Know

If you are living in an HDB flat, here are some important points:

• Approval not needed – You do not need prior approval from HDB to install a digital lock on your main door, as long as the conditions are met. However, it’s recommended to confirm with HDB or your contractor that the lock and installation comply with regulations. For Renovation Check HDB Guidelines
• Fire-rated doors – If your door is fire-rated, only fire-rated digital locks can be installed. The certification must remain valid after installation.

Being mindful of these rules ensures a smooth installation process without compliance issues.
