Smart locks are becoming more and more popular, and are due to their increased features. Those who like to pair or control a lock with smart devices will benefit from using a smart lock. Canadians who lose their keys or are often giving keys to pet sitters, house cleaners or their children will find that the ability to simply give out a PIN code is much easier. Changing your PIN in case you want to not let someone have access to your home is also much easier than changing the locks.
