How to buy the best smart lock

Not sure where to start when it comes to buying the best smart lock? Read our top tips for points to bear in mind when purchasing.

Can your smart lock be fitted retrospectively?

If you want to ensure minimal damage, or disruption, to your front door – perhaps you’re a renter – you may wish to opt for a smart lock that can be fitted retrospectively. These models will simply attach to your current deadbolt, giving it smart capabilities.

These options can tend to be a little more expensive, so it may be worth opting for a whole new lock system if you’re already thinking of replacing your front door, or your lock system.

Temporary access

If you’re looking for a smart lock because you want babysitters, cleaners, Airbnb guests and whoever else to be able to enter your home with ease, you may wish to opt for a smart lock that offers temporary key passes to visitors. Once your visitor has been and gone, you can prevent them from gaining access to your home again by simply cancelling their key.

Do you need a model that’s tamper proof?

If you’re concerned about security, a smart lock that alerts you when it’s being tampered with may be just what you need to put your mind at ease.
