Best Door Locks for Home Security | SafeWise

The Maxum is the next generation of lock security. Its solid, hardened steel casing and inserts make it drill-proof and impervious to attacks from crowbars and other common tools.

We especially liked that the unique lock style means unique keys, making them hard to duplicate. But keep in mind that if you need a duplicate key, or if you ever need to get the lock re-keyed, its uniqueness means you’ll have some hoops to jump through.

The Maxum lock is available in a variety of different finishes, and it comes with a high-security, box-style strike plate with two-inch, high tensile screws—not as long as the three-inch screws we prefer for a truly secure door, but better than the standard one-inch. Installation can be difficult, so you might want to have a locksmith on call just in case. You can order several Medeco locks for your home and have them keyed the same or differently.

Medeco locks are deadbolt only, so you’ll have to find a matching doorknob lock, but the deadbolts come in more than a dozen finishes, so you can find just the right match. Medeco is by far the priciest door lock on our list, but it’s top quality, and it comes with a two-year warranty.
