Are you planning to switch to a digital lock in 2026 but are unsure whether it will fit your existing door?
The good news is, you usually don’t need to replace your door to upgrade. Many digital lock models are designed to work with existing doors in HDB flats, condos, and landed homes across Singapore. With the right lock type and proper installation, most doors can be upgraded easily.
Here’s what you need to know before deciding if your current door is suitable for a digital lock upgrade.

Can Digital Locks Be Installed on Existing Doors?

Yes, in most cases, digital locks can be installed on existing wooden and laminate doors. One of the first things to check is whether your current door can support a digital lock. Here’s what matters:

  • Door thickness: Most digital locks require a minimum thickness (usually 35–50mm).
  • Lock cut-out compatibility: Your current lock hole or handle position should match the digital lock’s template, or can be adjusted by a professional.
  • Door condition: Ensure your door is not warped, damaged, or misaligned, which could affect installation or locking performance.

Not all doors are ready for a digital upgrade out of the box—getting a proper assessment is key.
