Before you commit to which smart lock you add to your home, it's useful to look at the different options.
There are two main types of security device - deadbolt locks and multipoint locks. As you may be able to see from our list, the former is more popular and widely available, but both have their pros and cons. Both terms have been carried over from the traditional door lock world but apply in much the same way here.
Deadbolt locks are the simplest of the two, with a bolt that is controlled by your smart lock system and that secures the door from the inside. Meanwhile, multi-point (or 'lever') locks include more than one bolt and offer a little more security. You will usually find these on more modern doors or those with a handle that must be pulled up before the door can be locked.
Generally speaking, deadbolts are easier to swap out for a smart alternative and also offer you more choices.
