A smart lock lets you open the door with a phone, code, fingerprint or remote control. This guide explains what to check before buying and how installation works.

1. Before Buying — Check Compatibility

A cylinder lock is required — smart locks only work with a euro cylinder (PZ cylinder). A door with a lever tumbler lock is not compatible.

• Measure the cylinder protrusion: how many mm the cylinder protrudes from the door surface (usually 5–10 mm)
• Check the PZ distance: the standard is 72 mm, some doors have 92 mm
• Check the backset: 35, 50 or 65 mm

2. Smart Lock Types

• Cylinder replacement — replaces the entire cylinder. Easiest to install, but does not work without power (requires batteries).
• Internal adapter — attaches over the cylinder from inside. Minimal change to external appearance.
• Full replacement lock — replaces the entire lock system. Most secure, but more expensive to install.

4. Important Safety Tips

• ✅ Always keep a mechanical backup key — batteries run out
• ✅ Use a strong PIN code (at least 6 digits)
• ✅ Update firmware regularly
• ⚠️ Do not use a smart lock outdoors without an additional protective cover — cold affects batteries
• ⚠️ Check that the smart lock is certified (CE + lock class)

5. Install Yourself or Call a Locksmith?

Cylinder replacement is DIY-friendly in most cases — 15–30 minutes, no special tools required. For a full lock replacement, we recommend calling a locksmith — incorrect installation can void the warranty.
