To know if your installed HDB door locks offer you the best protection and safety, you should first know how certain types of door locks work so that you can handle them properly.

This will give you freedom from using keys and can even send you data on your phone.


Common Types of HDB Main Door Locks

You can get HDB door locks for your nearest handyman to install in many shapes and designs. However, each door lock differs in its features. To give you an idea, we’ve included the most common type of HDB door locks to choose from.


Mortise Lock

This is probably the most common type of lock installed by cheap handyman services in HDB condominiums in Singapore. To fit a mortise lock into the door, you need to first cut a rectangular pocket which comes with a sprung latch on top. Once you pull down the handle, the latch retracts as it is connected to the handle. Contact a door lock and latch repair services should your mortise lock experience any problems



This type of lock has some similar features to a mortise lock. One difference is that it works on a spring and thus locks the door when you shut it from outside. However, you would need to self-lock once you’re inside your home. It would be more convenient to hire a handyman to install this type of lock for you instead of doing so on your own.



This type of lock doesn’t make use of any spring or bolt and has to be manipulated by hand from the inside. That said, they can be prone to a number of problems such as a broken key stuck inside. In that case, you’ll need to have your door lock replaced.


Digital door locks

Digital door locks are smart door lock systems and use access codes instead of keys. As a result, you don’t need to worry about falling into locksmith scams when having them repaired.


Door handles

Door handles are important so that you can open the door properly and so that the elderly and children can gain easy access. Similar to window handles, they also come in different shapes and sizes.


Pros and Cons of Digital Door Locks

What Do I Need To Know About HDB Door Locks?

It’s normal to get confused by having various door lock options since they come in many designs, shapes, and sizes. This is because all locks are unique in one sense or the other. Though when it comes to the main door of most HDB flats, mortise locks are those commonly used.

If you’re thinking of opting for an HDB main door lock replacement, then you may want to explore the following facts regarding the locks most HDB flats use:

  • Most people look for cheap handymen to install either common simple key locks or deadbolt locks.
  • Key locks have a small cylinder that connects one side of the door to the other.
  • For deadbolt locks, your key controls the lever and accordingly either closes or opens the doors. In an unlocked door, the tang remains in the rest within the cylinder. When locked, the tang partially comes out to hook itself to the mainframe.
  • Tubular locks are the most common type of door locks installed by locksmiths or handymen on wooden doors. A bore is made at the door to install these types of locks. These are mainly used in the interiors of your HDB flats. You can have the option of the knob with a push-button.
