What to look for when buying a Smart Lock?

There are a few things to think about while looking for a Smart Lock.

  • Type of Lock: There are two types of smart locks such as deadbolt and lever-style. The former is intended to replace your existing deadbolt, whereas the latter combines the lock and the door-opening lever into one unit.
  • Design: Your smart lock should match the rest of your house. The majority of locks come in several types and finishes, including brass, silver, and bronze.
  • Security: Smart locks come with one or more entry options; it's up to you to choose which one you like.
  • Keys: Some smart locks have a classic keyhole, just like a regular lock. Some can even be re-keyed to make the transition easier.
  • Keypads: The most popular form of access; most smart locks allow you to create and manage dozens, if not hundreds, of key codes.
  • Virtual keys: This feature allows you to send a virtual code to others who can then unlock your door using the smart lock app on their phone. You have control over how long these codes are live.
  • Fingerprint Reader: Some smart locks now incorporate fingerprint readers, so you don't have to remember a code or your keys to gain access; simply put your finger against the reader to gain access.
  • Connectivity: Smart lock must be connected to your home network to be controlled and monitored remotely.
  • Setup: Some smart locks replace your existing deadbolt, while others sit on top of your current deadbolt, allowing you to maintain your keys.

One of the first things you should consider is the cost of replacing your existing lock. After all, a smart lock is significantly more expensive than a normal lock. There are a few smart locks in the $100 range, but you'll have to spend more if you want a lock that you can control from anywhere that with features like voice commands and push alerts.

In general, Door locks and deadbolts provide varying levels of security and convenience to users. The cost of Smart Lock depends on the brand, model, and features. Here is the comparison of some best Smart Locks. You can select the best smart lock as you wish.
