Smart Locks
“With remote access and compatibility with your smartphone, smart locks are excellent for all entry points,” says Klimaszewski. “They allow you to monitor and control your locks from anywhere.”
Smart locks are a favorite of Airbnb hosts, because a guest can download the app that operates the lock and open and close the door from their mobile device for as long as the host gives permission. It’s a handy tool I’ve used several times.
The Wi-Fi device that operates the lock takes the place of a keyed lock set or keypad, but the lock itself is just a deadbolt or knob lock. It installs like a conventional lock. The only maintenance required? An occasional recharge or fresh battery.

Euro Profile Cylinder Locks
As the name suggests, this type of lock is more common in Europe — especially the United Kingdom — than North America. It’s best suited for patio and sliding glass doors, according to Klimaszewski.
The cylindrical lock set fits into a hole in the door. A key or handle spins a cam in the middle of the door that moves a bolt. In the case of sliding doors, a hook moves and latches onto another hook set inside the door jamb. Both sides of the cylinder may be keyed, or one side may have a handle that operates the lock from inside.

Padlocks
Padlocks aren’t elegant, but they work.
A typical padlock consists of a U-shaped shackle and keyed or combination lock body. When the lock opens, it frees one side of the shackle from the lock body, allowing the entire shackle to spin freely. You lock it by pushing the free end of the shackle into the lock body until it clicks.
Padlocks are removable and portable. But before use one, you must install a somewhat unsightly latch on the door and another on an adjacent jamb or post. You can make padlocks work on entry doors, but they’re better for gates, garage and utility room doors, where the unsightliness doesn’t matter.
