Are smart locks secure?
Yes, provided you choose brands with AES-128 or higher encryption and regular firmware updates. Nuki, Yale, and Tedee all publish their security protocols and undergo third-party audits. The real risk is not remote hacking — it is the physical security of your underlying cylinder. No smart lock improves a weak cylinder: if yours is vulnerable to lock-picking or bumping, replace the cylinder first before adding any smart device.
Do I need to replace my whole lock?
In most cases, no. The Nuki 4.0 Pro, Yale Linus L2, Tedee GO, and August Pro all retrofit over your existing lock — they only modify the interior thumb-turn side of the door. The only model in this guide that requires a full deadbolt replacement is the Philips Easykey 5000, which offers fingerprint access in return. Before buying, confirm your cylinder profile is compatible (European profile cylinders for the European models).
What happens if the battery dies?
All models have an emergency solution. Battery-powered models (Nuki, Yale, Tedee) give weeks of low-battery warnings via app and have enough reserve charge for several days. Your physical key always remains functional — a smart lock does not disable the cylinder. The Philips Easykey 5000 has a built-in rechargeable battery and a micro-USB emergency charging port on the exterior, so you can charge it without opening the door.
