Why the HDB Letterbox Lock Is Important
Your letterbox lock keeps your mail safe. Why is this big?
- It protects your letters and important papers.
- It stops people from stealing your NRIC card copies or bank statements.
- It keeps online shopping parcels safe if they are small.
- It helps stop identity theft (when someone pretends to be you and does bad things).
A good lock means you can sleep without worry!
Types of HDB Letterbox Locks in Singapore
There are different kinds of locks for HDB letterboxes.
Standard Cam Lock
This is the most common one in old HDB blocks. It uses a normal key.
Combination Lock
No key needed! You turn the numbers to open it. Good for families because kids can remember the code.
Digital Letterbox Lock
This is a modern one! You use a password or card. Many new BTO flats have this. It is keyless and cool.
When Should You Replace Your Letterbox Lock?
Change your lock if:
- You lost your key.
- You move into a new (resale) flat (old owners might have keys).
- The lock is jammed or stuck.
- You think someone stole mail from it.
