Europe is a patchwork of door types. Still, three building blocks appear in most markets: the euro-profile cylinder, the DIN-style mortise body and the multipoint lock. Knowing them helps you decide which smart locks are realistic.
The euro-profile cylinder
Euro-profile cylinders (DIN 18252 and EN 1303) are the key component in most European locks, and the key hole in the faceplate has the typical keyhole outline. Many smart locks replace only the cylinder and electronics, but the full lock body remains. The 68 mortise body in our photos has a euro-profile cylinder opening.
DIN-style mortise bodies
Interior and many apartment doors use mortise bodies defined by DIN 18251. A common designation is 55/72/8: a 55 mm backset, a 72 mm distance between the cylinder and the spindle, and an 8 mm spindle. Other backsets such as 35, 40, 45, 50 and 60 mm exist. Smart handles that fit these bodies must use the same spindle and spacing.
Multipoint locks on entrance doors
Many European entrance doors, especially uPVC, aluminium and composite doors, use multipoint locks with bolts at several points. They are a different mechanism from single mortise bodies, and we do not list multipoint systems. For these projects, ask whether a smart cylinder or a different product suits the door.
What from our range fits
| Door situation | Options in our range | What to confirm |
|---|---|---|
| Single-bolt mortise entrance door | Automatic locks on the 68 body (A60S, AC38S, B65S) with 6085, 6090 or 5072 rear-lock options | Backset, centre distance, faceplate, door thickness |
| Interior or apartment door | B7 with true mortise or bottom-insert body; T6S | Spindle size, backset, handing |
| Wooden interior door | B6 / B36 on the 5050 body | Mortise pocket size and backset |
The 5072 rear-lock option has a 72 mm centre distance, the same spacing as the 55/72/8 standard, but a 50 mm backset instead of 55 mm. Always compare drawings; do not assume a match from the label.
Features Europe tends to value
- Languages: supported versions offer up to 23 interface languages.
- Matter and Tuya: Matter versions are available for selected dual-screen models.
- Certificates: CE and RoHS certificates are available on request.
- Cylinder grade: ask for the test report if your market needs EN 1303 grading.
Practical steps
- Photograph the door edge and faceplate.
- Measure thickness, backset and cylinder spacing.
- Check whether the door is single-point or multipoint.
- Send everything to us for a fit check.

Frequently asked questions
What is 55/72/8 on a European lock?
It means a 55 mm backset, 72 mm cylinder-to-spindle distance and 8 mm spindle under DIN-style naming.
Do you offer smart locks for multipoint doors?
Multipoint systems are not listed in our range. Ask us for options for such doors.
Does the 5072 rear lock match the European 55/72 body?
The centre distance is the same, 72 mm, but the backset is 50 mm instead of 55 mm. Confirm with drawings.
