Why is a digital door lock a better choice than a traditional lock?

- Reduces the risk of theft—digital locks often come with alarms that alert you when tampering is detected, and some models auto-lock when the door is closed.

Why switch to a digital door lock instead of a traditional doorknob?
Digital door locks are becoming increasingly popular as they help solve common problems associated with traditional doorknobs, such as security, carrying keys, and durability.
Superior security
Traditional doorknobs are vulnerable to break-ins, especially from lock-picking tools or generic mechanical keys. Digital door locks come with advanced security systems such as auto-lock, tamper alerts, and multiple access methods like passcodes, fingerprints, RFID cards, or mobile applications instead of keys.
No need to carry keys — say goodbye to lost keys.
A common issue with traditional locks is losing or forgetting keys, or locking them inside, which can lead to wasted time or locksmith fees. Digital door locks eliminate this problem by using fingerprints or passcodes. Some models with app support allow remote unlocking via smartphone.
Convenient access
Digital door locks make entry and exit easier. No need to fumble for keys in your bag or deal with multiple keys.
How is it more convenient than a traditional doorknob?
- Unlock with a simple fingerprint scan, passcode, or mobile app.
- Set custom access permissions for family members or office staff.
- Perfect for homes with children, elderly, or guests who don’t need a physical key.
Durability of digital door locks — suitable for both indoor and outdoor use
Standard doorknobs may lack durability, especially when installed outdoors and exposed to rain or moisture. Waterproof digital door lock models solve this issue.
- Features such as IP65-rated waterproof and dustproof protection make them ideal for outdoor installation.
- Made from high-quality materials like stainless steel or aluminum alloy, resistant to corrosion.
- Some models are designed to withstand a wide temperature range for both indoor and outdoor use.
