Smart Locks Buying Guide

Smart locks have gone mainstream, and for good reason: no more lost keys, no hidden spare under the mat, and the ability to let people in remotely or with a code. But there is real variation in quality and fit, and a smart lock is only as good as the deadbolt it drives and the installation behind it. Here is what to weigh before buying.

Types of keyless entry

• Keypad locks — enter a code to unlock. Simple, reliable, no phone needed, and easy to change codes between users.
• Bluetooth locks — unlock from your phone when nearby; no internet required, but no remote access from away.
• Wi-Fi locks — full remote control and notifications from anywhere, at the cost of more battery use and a dependency on your network.
• Fingerprint (biometric) locks — unlock by touch; fast and keyless, though readers can be finicky in cold or wet conditions.
• Retrofit vs. full replacement — some smart locks keep your existing deadbolt and add a motor on the inside; others replace the whole lock.

What to check before you buy

Does it fit your door?

Check the door thickness, the backset, and whether your door is set up for a standard deadbolt. A retrofit model that keeps your existing exterior hardware can be the easiest upgrade; a full replacement gives you the most features.

Will it survive a Toronto winter?

This matters here. Look for a lock rated for outdoor temperature swings, and be realistic about fingerprint readers and touchscreens in freezing, icy conditions. A keypad with physical buttons or a key-backup option is often more dependable in deep winter.

Batteries and backup

Smart locks run on batteries. Check battery life, whether it warns you before dying, and what the backup is if power runs out — a physical key override or an emergency external power contact. You never want to be locked out because a battery quit.

Connectivity and app

Decide whether you actually need remote access. If you do, a Wi-Fi model (or a hub) is worth it; if you just want keyless convenience at the door, Bluetooth or a keypad is simpler and uses less power.

Great for rentals and Airbnbs

Keyless locks shine for landlords and short-term hosts: issue a unique code per guest or tenant, change it between stays, and never coordinate a key handover again. It removes lost-key headaches and the cost of rekeying between every occupant.

Why installation matters

A smart lock installed on a misaligned door will jam, fail to lock fully, or drain its battery fighting the bolt. The electronics are only half the job — the deadbolt has to throw smoothly and the door has to align. A locksmith makes sure the hardware fits your door, works reliably in our climate, and is set up correctly, then walks you through codes and users so it just works from day one.
