Digital Door Lock Buying Guide: Avoid These 7 Common Mistakes

The purchase of a Digital Door Lock is not only about giving up old-fashioned keys anymore; it is about finding the proper combination of protection, convenience, and durability. As there are plenty of different lock models on sale, it is possible to get caught in superficial aspects and prices, while forgetting about what really counts.

It is not convenient to have a lock which does not fit your door, or does not provide any options for backup access, or works badly under severe conditions.

Here is the list of seven typical mistakes when purchasing a Smart Door Lock, and how to prevent them. 

1. Choosing a Lock with Only One Unlocking Method

Most customers buy smart door locks which is capable of offering either fingerprint or PIN, believing that one method would suffice. This is not the case since no single access method can be considered completely reliable. You might face difficulties opening your door if your fingers are wet, your fingerprints are old, you forgot your PIN code, or there are some problems with the sensor.

Thus, a good Digital Door Lock must have a variety of access methods including fingerprint, PIN code, RFID card, mobile application, Bluetooth technology, and even an emergency key. 

What to Look For- 

• Fingerprint access

• PIN code

• RFID card

• Mobile App

• Mechanical Key

• Temporary Guest Password

2. Buying a Lock Without Checking Emergency Backup Features

Smart features can be very interesting, but emergency features should also be a priority. A lot of people do not think about how they will manage if their batteries die or their electronic fails to work.

Before purchasing one, see if it has a back-up key, emergency power source using USB, and low battery warnings. This way, you can avoid being locked out.

However, not all fingerprint digital door lock will be compatible with all kinds of doors. The danger in purchasing without verifying whether there will be additional installation costs or even discovering after buying the product that the lock cannot even be installed on your door!

Always Check

• Door thickness

• Door material

4. Overlooking Battery Life and Power Management

Performance of the battery is directly related to the experience that you will have with the digital lock. There are some customers who will not look at the battery specification until they start receiving battery reminders regularly.

It is important for you to choose locks which have batteries that last longer and operate efficiently. 

Check Before Buying

• Average battery life

• Low battery alerts

• Emergency power support

• Battery replacement process

The intelligent lock is way more than the physical lock itself. The regular updates to the software, the user-friendly application for your phone and the customer service can be crucial for the overall user experience.

Think about manufacturers that offer regular software updates, reliable mobile applications, proper customer service, warranty and installation services. 

Things to Compare

• Mobile app features

• Software updates

• Warranty period

6. Forgetting to Consider Weather Resistance

Should you be installing an entrance that has exposure to sun, rain, moisture, or dust, then the need for weatherproofing will be crucial.

An outdoors-friendly lock will ensure that the components inside remain protected from the elements in India’s varied weather conditions.

• Independent homes

• Outdoor gates

• Semi-covered entrances

7. Overlooking Build Quality and Locking Strength

Smart technology alone doesn't make a lock secure. The physical construction is equally important.

Evaluate Before Buying

• Metal body construction

• Number of locking bolts

• Anti-tamper design
