What to Consider Before Choosing a Digital Lock?

Tips for Choosing the Right Digital Lock for HDB Gate
With so many options, it helps to approach your choice methodically. Here’s a step-by-step approach:
1. Measure Your Gate
- Check the thickness, height, and clearance of the gate. Take note of the swing direction and the available mounting surface.
2. Define Your Priority
- Is your main goal better security, faster entry, or remote control? Decide what feature matters most.
3. Consider Daily Users
- Think about everyone who’ll use the lock. Young children, elderly parents, and helpers may need simpler access modes like RFID or PIN.
4. Choose a Backup
- Always ensure there’s a backup entry method—such as a mechanical key or admin PIN. Locks can fail, and batteries can drain.
5. Check Compatibility with the Main Door Lock
- Some digital locks clash with main door lock handles when mounted too close. Check alignment carefully, especially in older flats.
Maintenance and Care
Digital locks last longer with basic upkeep. Here’s how to preserve function and appearance:
- Wipe the keypad and fingerprint scanner with a soft cloth
- Replace batteries every 6–12 months
- Test access codes and cards regularly
- Avoid forceful handling or slamming the gate
- Keep backup keys in a safe, accessible place
Manufacturers usually recommend checking firmware updates if your lock connects to an app. Staying current ensures you benefit from security patches and new features.
