What is a digital door lock?

To put it simply, digital door locks, keypad locks, e locks, keyless door locks or smart locks are locks that operate by means of an electric current. They function very much like the traditional padlock, but instead of using a key to unlock the door, digital door locks use actuators to link the locking bolt mechanism to a small motor, controlled electronically

Digital door lock vs Smart lock

Most people use the terms digital lock and smart lock interchangeably, but there is a small difference when it comes to these types of door locks. With a digital lock or keypad lock, you still need to be physically present to unlock the door. On the other hand, a smart lock is a digital lock door with Wi-Fi or Bluetooth integration, so you can control and access the lock remotely via your smartphone.

Traditional lock vs Smart door lock

Traditional locks, usually padlocks, deadbolt locks, mechanical locks, door latches, mortise locks, or knob locks, aren’t that much different from smart locks. In some cases, a smart lock may use the existing padlock mechanism but the lock is engaged electronically. When it comes to keeping your security door locked and protected from intruders, you’re getting the same secure lock. However, smart locks do include additional features like an alarm and a notification direct to your phone should there be a break-in.

Convenience-wise, it’s much easier to enter a passcode or use your fingerprint to enter your front door, rather than spending minutes fiddling around searching for your keys. Plus with a smart lock, you can even lock the door remotely—especially when you’re late for work and think you might have forgotten to do so.

You will, of course, be spending so much more to replace your padlock with a new smart lock, but if you do decide that the extra cost is worth it, you will enjoy all the benefits of a smart lock:

Are you the type that spends minutes in front of your front door fiddling for your keys? 

1. Offer better convenience

With a digital lock or smart lock, say goodbye to neighbours staring at you while you awkwardly search for your keys to prove that you’re not an intruder. Just enter the passcode or use your fingerprint, and you’re in! Plus with a smart lock, you can even lock your security door remotely.

2. Offer remote access

A digital lock or smart lock is also perfect for those with friends that come around often or if you need to let a caregiver in for your elderly parents. No more stashing a spare key under the flowerpot or floor mat! Just simply give them the PIN number (which you can always change later) or with a smart lock, give them access remotely through the smart lock’s app. You can also allow users to enter your home with a PIN during specific times too, say Monday to Friday from 12 pm to 2 pm for instance if you would like to prevent any rude shocks.

3. Offer high security

The lack of a physical security lock does mean that there are fewer ways for someone to break into your home, especially if your smart lock doesn’t even have a keyway to pick. And with a smart lock, the ability to change the PIN anytime eliminates the need to change a complete set of locks and keys in the event you feel that security may be compromised with your current PIN.

With a digital lock or smart lock in place, you can set an alarm to go off if there is a potential break-in. With a smart lock, you will also receive a notification for unwanted entry into your home. Some digital locks or smart locks also come with a scramble code function to add more numbers before or after your PIN code, just in case you’re worried someone is looking above your shoulders as you type your password.

How long do digital locks last?

No matter how good your digital locks are, they won’t last forever. According to numerous sources, digital locks have a lifespan of 5 years or less. Some brands and varieties last longer, while others break down after using for a couple of years. If you want to extend the lifespan of your digital and smart lock, we’ve got some tips for you: 

  • Keep it clean as dust and grime will damage your lock.
  • Use only the right cleaning products. Don’t use petroleum-based or harsh chemicals to clean or it will deteriorate the condition of your digital lock. 
  • Don’t fiddle with the keypad or risk damaging the lock. 

What are the disadvantages of using smart locks?

One slight disadvantage of using a keypad lock for a door is that it runs on batteries. Using a Samsung smart lock as an example, Samsung says its electronic locks should last about 9 to 10 months when powered by good quality alkaline batteries. This can vary depending on how often you use the smart lock. You may also need to check your digital lock or smart lock for battery leakages every few months.

You might be worried if people could “hack” into your smart lock. Our advice is to always purchase your smart lock from reputable brands, such as Yale or Samsung. These brands outfit their smart locks with better password encryption standards to prevent possible hacking. 

When setting the password for your door locks, remember not to key in numbers that contain any personal information like birthday, anniversary dates, IC number or address. Don’t come up with a random pin code that none of your family members can remember either.

Here are some tips to set a secure smart lock password: 

  • Don’t choose a personal passcode like birth date or any number someone could guess after doing a little digging into your personal life. 
  • Keep it short and simple.
  • Combine meaningful numbers in random order. For example, if you have a family of four, combine the birthday month to create a strong password. To make it harder for intruders to guess, randomise it. 
  • Create a strong password with an acronym like “We Are Happy Family”, which would translate to WAHF or 9243 in numbers. 
  • Change the passcode to your smart lock every few months. 
  • Don’t leave any paper trails for people to find. Memorise the password instead.
