I just moved into my newly renovated 4-room resale HDB unit with my partner and our newborn baby. The first few months were particularly challenging for us, as we eased into the home using the default HDB door lock that unlocks with keys. We were terrible with our keys and security and we even had instances where our keys were at the door, overnight.
Upgrading HDB mechanical door lock
As with most HDB units, the HDB main door provides a default one-piece mortise lock that includes both the handle and lock. We settled for a basic add-on lock option that unlocks our door with our fingerprints and the regular PIN code, while retaining our existing HDB mortise door handle with lock.
Want to go key-less
Our topmost consideration for a digital door lock was simply to go key-less, since we didn’t need any other special smart functions.
While our current smart door lock works for us now, we think that it is good for us to be informed about the different digital door lock choices that we have, should we decide to upgrade it in the future when our family needs change, or replace our current smart door lock when it reaches the end of its anticipated lifespan of 5 years.
Child-friendly digital door lock
For our next digital door lock, we hope to consider functions like child safety lock and some form of video viewer feature, as we are still lacking a smart door viewer, since both of us work from the office. Additionally, I would also want to go for a well-designed door lock with a durable built quality.
Goodbye to getting locked out of your house when you misplace your keys. Beyond the convenience of going keyless, a smart door lock ensures that your home is always secure with the auto-lock function and security alarm. Here are our top picks of the best digital door locks from deadbolt, rim, and mortise lock mechanisms.
