Building a solid home security system requires multiple products working in tandem, though not all upgrades need to fall into the high-tech category. For example, switching out your front door’s regular lock and installing an electronic deadbolt is an easy upgrade—and a relatively affordable one.

There are basic, under-$100 models that let you lock with the press of a button and unlock with a code, as well as more expensive, full-on smart locks that you can control remotely. Some models we recommend do both, with the option to connect to your phone if you want. To help you find the best electronic deadbolt for your security needs and budget, we’ve included advice on what to factor in as you begin your search.

Basic Deadbolts: There are electronic deadbolts that work with or without wireless access. Regardless of wireless connectivity, both styles are available with or without a physical key. A good first decision to make is whether you’re more comfortable knowing you can unlock the door the old-school way. The most basic electronic deadbolts have a keypad or touchscreen with multiple access codes for entry, and can require a key as well or not, depending on your preference.
