Aqara Smart Gate Lock U500: Gate Fit Checks

The Aqara Smart Gate Lock U500 is a gate-specific product with an integrated mechanism. Its preparation is different from a conventional single-cylinder deadbolt, so start with the exact product record and do not apply deadbolt measurements from another Aqara lock.

Illustrative mechanism comparison only: the exact U500 Gate model has its own preparation and installation requirements; the deadbolt example is not a substitute fit check.

Compare the gate and cutouts

The U500 record identifies model DL-D18D and describes a dual-hook integrated mechanism with a through-lock cylinder. Its published preparation calls for two 12 mm holes and one 50 mm hole, a door thickness of 22–28 mm, a 40–45 mm backset, and a 3–7 mm gap. The door and frame are expected to be flush in the documented setup.

Measure the existing gate at the locations required by Aqara’s current guide. Check the mechanism, hole positions and sizes, thickness, backset, gap, and frame relationship together. A value that matches while the cutout layout or integrated latch differs is not a confirmed fit. Do not enlarge or alter a gate based on these summary measurements alone; use the exact installation template and qualified help where needed.

Schematic only, not a drilling template: confirm exact cutout locations and sizes, dimensions, frame alignment, and installation conditions against Aqara’s current instructions for the exact model.

Confirm operation and smart-home requirements

Verify that the gate’s movement and frame leave enough room for the installed lock and supplied components. The record describes Matter support that requires a compatible Matter controller and Thread border router. Those are setup requirements after the gate preparation is verified; they do not prove that the integrated mechanism fits the gate.

The product record is specific to the U500. It does not establish compatibility for Aqara U500 Rim or Glass variants, or for other smart gate locks. If the gate differs from the published conditions or the installation guide does not answer a necessary question, treat compatibility as unknown and confirm with Aqara before purchase.
