From the invention of locks and keys, we have trusted key door locks for the security of our family and work premises. The only issue arises is when we end up losing the key than the only option is to either break the lock or get a Keysmith to make a new key. Many of us have to make spare keys as the adults come home in the evening from work while the kids come in the afternoon.

Do you often forget your keys in the car or at times in the office and end up standing in front of the door waiting for another family member to come and open the door? Do you want a lock without keys? If you have answered yes to either of the above questions, then the New Security guard is ideal for you.

Gone are the days of having to remember where the keys are or having to make spare ones because the smart electronic door lock has arrived making life much easy and secure.  While buying a door lock there are many things one has to consider.

Unlike the key door locks in which you use to look for style and strength, with the keyless door lock it’s different.Here is the ideal guide that is going to help you in buying the lock that fits your requirement, style and other features to look.

Type of Lock: Touch Screen / Sensor or Keypad

Keyless door locks come in two types: keypad and touchscreen. With the keypad one, you get a push-button keypad with numeric digits 0-9 along with a lock and unlock button. The keypad comes in a variation of locks in which each key can have its push button or a group of digits might share a push button.smartlock-touch-sensor

The touchscreen opens with the identification of your fingerprint as like a Bio-metric fingerprint reader. This type is useful to blinds too which gives people with impaired vision a feeling of self-ability.  In case of the fingerprint malfunctions, we can use the backup codes to open it which might happen sometimes.

Master Code/ Passage Code

Keyless door locks open by entering codes that you have saved. There are two codes that the lock accepts 1) master code 2) passage codes. The master code allows you to set up all passage codes and the passage code is for users, giving you full protection against any unwanted intrusion.

Customizable User Codes best for Guests

In case you have installed the lock in your home then each family member will have the master code, but, let’s say everyone has their own entry time and they can set a custom code for them. This helps for precise control for offices to time limit different level of staff entry. If a relative is visiting for a while, you can give them a customized code as well that works for a certain time and become invalid after certain days.

The keypad is ideal for night entries as it has an electronic lit panel that allows you to quickly enter your code without having to use any torch lights.

Auto-Lock for Door Locks

With a traditional key lock any intruder can easily open the door without keys, but, the keyless door lock is different in terms of security. Traditional locks, you have to be careful to lock your door when you go outside. Smart locks, you don’t need to worry to lock your door, the door will automatically lock within three seconds once you come outside.

Smart Lock Battery & Lifespan

Being an electronic device, the Smartlock needs a power supply to work and they use standard 4 AA or 4 AAA batteries to work.The battery can last more than one year with moderate use with 15-20 entries per day.

As the keyless door lock runs on batteries, the lifespan varies by the number of times the lock wakes up per day. Most of these Number Locks are offering 12 to 20 months of battery life with moderate use like 10 entries per day. The Smart Lock can warn you with a beeper installed that lets you know when the battery is low and provides ample time for you to change the batteries.

Smart Lock Fits Both Left/Right side

For new homes, it does not matter. You can purchase door locks according to your need. But, in case you are planning to replace your old doors key locks with new keyless door locks, better you purchase door locks that fit both left/right sides.

Smart Lock Remote Connection to Wi-Fi

If you have a Wi-Fi connection, then you can also connect your door lock with your Wi-Fi connection and with a Wi-Fi remote you can access your door lock remotely anywhere from the world. I would say a Smart Lock and an IP Camera both synced with your Smart Phone can convert your home into a Smart Home.

Smartphone Connectivity with Smart Lock

Nowadays Smartphones are in everyone’s hands and if your door lock is connected to your Smartphone, what better can one ask for. You can check the battery status, a number of times the lock use per day, door lock / unlock status etc. For Smartphone connectivity you require using built-in Bluetooth in your door lock to pair with your Smartphone. To operate the lock with your Smartphone, you will have to be in the range of Bluetooth connection.

A Protecting Sliding Cover

Smart Lock Activity Notification

With the traditional lock you can never know when someone enters the home but, with the keyless lock, this is going to change as you can get notifications on who enters or leaves home while you are away. For this, you receive emails or push-notifications every time the lock is opened or locked. This feature is ideal for parents who want to know when their child is home and when they are not if you already assigned a custom code for each of them. Yes, this feature comes with a remote access fee, but, it’s worth the pay, after all, it’s about knowing the whereabouts of your kids.

Technology has always been found ways of making our lives easier at the same times secure, and the keyless door lock is no different. It is not just the modern trend but, secure and safe for your family. It may cost more than the traditional lock but, no pay is much over the security of your loved ones.
