Our Smart Lock Buying Guide

Have you ever lost your keys or just fumbled around trying to unlock your door? A smart lock is an excellent way to unlock your door using an app on your phone or a button on a keypad. It provides people with more flexibility and convenience when it comes to locking and unlocking the door.

There are several different types of smart locks on the market. A common style of smart lock uses Bluetooth connectivity to automatically unlock the door when you are in proximity. You can also unlock a Bluetooth smart lock using your phone or a key fob. If you also want to increase security, consider using a biometric smart lock. It uses your fingerprint to allow entry. You can easily program the lock to read multiple people’s fingerprints.

RFID smart locks use a card or key fob to unlock the door. They typically lock automatically, so it’s important to have your key fob on you at all times. A keypad smart lock uses a pin number to unlock the door. You can program in different codes for different people and change codes as needed. A WiFi smart lock uses an internet connection to function. You can lock or unlock the door using your phone, usually from anywhere else in the world.

DWYM Fun Fact

If you have a security system or are considering getting a security system, ensure that your smart lock can integrate with it. When all of your home security software and hardware works together, you can have more control and visibility, and can more effectively monitor who is entering and exiting your home. Plus, having just one application to check as opposed to multiple offers more convenience. Several smart lock systems can work with legacy and new security systems.

The Smart Lock Tips and Advice

  • One of the most important features to look for when you’re considering a smart lock is access logs. These can track who enters the home if you give people specific keys. It can also track the date and time when the door was locked and unlocked.
  • Having the ability to lock and unlock your home remotely is a handy feature to have. It can be used to let your kids in when they come home from school or to allow maintenance or cleaning people access when you’re unavailable.
  • If you want to scare away burglars or unauthorized visitors, consider getting a smart lock with a tamper alarm. It notifies you when someone is trying to break into your home by interfering with the lock.
  • While changing your lock, you may also want to consider looking at the integrity of your door. A weak door may not provide any security regardless of how safe your lock is. Consider installing a heavy-duty door or additionally securing the hinges.
