After Buying a Digital Lock in Singapore: What to Do and What to Avoid

Just installed a digital lock on your main door? Congrats on upgrading to smart security! Now you can unlock your door with ease, enjoy a sleek design, and feel safer at home—all without using keys! But what comes next? Many homeowners make mistakes after installing a digital lock, simply because they don’t know what to do—or what not to do.

In this guide, we’ll share the right steps to take after buying a digital lock in Singapore and highlight the common mistakes you should avoid. Whether you live in an HDB, condo, or landed property, these tips will help you get the best out of your new lock.

What to Do After Buying a Digital Lock

Register All Users

After installation, make sure to register all users who will be using the lock. This includes family members, domestic helpers, or anyone who needs regular access. Most digital locks allow you to add multiple fingerprints, PIN codes, or access cards.

Tip: For extra safety, assign different codes or fingerprints for each person. That way, if someone forgets theirs, you’ll know whose it was.

Change the Default Password

Your digital lock usually comes with a factory-set password. Don’t keep it! Always change the default code to your own unique PIN. Pick a code that’s simple for you but tricky for others to figure out.

Tips: Avoid using simple codes like “123456” or your birthday—they’re too easy to guess.

Understand All Access Methods

Most digital locks offer multiple ways to unlock—such as fingerprint, facial recognition, PIN, RFID card, mobile app, or even mechanical keys. Learn how each unlocking method works to use it with ease!

Tips: Try all the methods once or twice after setup to ensure everything works smoothly.

Test the Emergency Features

Does your lock come with a mechanical key or emergency battery backup? These are very important in case your lock’s battery dies or malfunctions.

• Check how to insert the emergency key.
• Locate the backup battery slot.
• Keep your emergency key somewhere safe, but easy for you to reach when needed.

Replace the Batteries on Time

Digital locks run on batteries, and forgetting to replace them can lock you out. Your lock will beep or blink when the battery’s running low—don’t miss the warning!

Don’t Forget to Register Your Warranty

Some people skip this important step. Always register your product warranty on the official website after purchase to ensure you get proper support and coverage if anything goes wrong.

Test All Functions

Ensure that all access methods (keypad, fingerprint, RFID, etc.) are working correctly. 

Download the Mobile App (If Available)

If your lock supports Bluetooth or Wi-Fi, download the brand’s mobile app.

• Remote unlocking
• Access logs
• Notifications when someone enters
• Temporary Access

This is especially useful for parents, rental units, or those who travel often.

Check for Updates

Updates often add security fixes to protect your lock from the latest hacking methods.

Fire Safety Considerations

In Singapore, if you’re living in an HDB or condo, always check whether your digital lock fire-rated or non–fire-rated. Ensure it comes with a valid Certificate of Compliance (COC) and is SCDF-approved to meet safety regulations and avoid potential issues.

What to Avoid After Buying a Digital Lock

Don’t Share Your PIN Code Carelessly

Your PIN code is like a house key—don’t share it with too many people. If you must give someone access, consider creating a one-time PIN (available in many lock models).

If your lock supports temporary access, use that instead of sharing your main code.

Battery Care

Digital locks run on batteries, so check and replace them regularly to avoid getting locked out. Avoid mixing old and new batteries, and don’t use low-quality or cheap batteries, as they may leak or damage the lock.

Don’t Use Wet or Dirty Fingers

Many fingerprint locks won’t work well if your fingers are wet, oily, or dirty. Make sure your fingers are clean and dry for a quick, smooth scan!

Avoid DIY Repairs

If your lock starts acting up, avoid opening it up yourself. Instead, contact the supplier or an authorised technician. DIY fixes might avoid your warranty or damage the lock further.

Keep the User Manual Safe

Store your user manual in a safe place. You may need it later to reset your lock, register new users, or troubleshoot.

Warranty Issues

Following the manufacturer’s guidelines, including using recommended batteries, helps ensure proper operation and avoids warranty issues.

Final Thoughts

Buying a digital lock is a smart move for any modern home in Singapore—but what you do after the purchase matters just as much. By following the tips above, you’ll ensure your lock stays secure, convenient, and long-lasting.
