ASSA ABLOY SMARTair Knob Cylinder - Update-on-Card, HID iCLASS, IP55 - SNCW43X030E10MI
The ASSA ABLOY SMARTair Knob Cylinder in the Update-on-Card tier (SNCW43X030E10MI) is an electronic knob cylinder that replaces the mechanical cylinder in an existing door, converting it to HID iCLASS RFID credential access with no wiring through the door.
In Update-on-Card operation, access rights ride on the user credential and refresh as cards pass online update points or wall updaters, so permissions stay current across a site without every door being wired or networked. Credentials are written with the SMARTair USB encoder and managed through the TS1000 software.
This model carries an IP55 environmental rating and is battery powered. Openow smartphone access is not included on this cylinder - it can be added with the SMARTair BLE module, or choose the Update-on-Card + Openow model with mobile access included.
Usually ships in 30-35 business days. This cylinder is a special-order item.

Full Specifications
Cylinder Profiles
The SMARTair electronic knob cylinder is offered in several profiles so it can replace the existing mechanical cylinder in most door types. Confirm the profile your door uses before ordering:
- Din Double cylinder - credential operation both sides.
- Din Double thumbturn cylinder - credential outside, thumbturn inside.
- Din Half cylinder - single-sided.
- Din Oval e-cylinder.
- Australian Din Oval e-cylinder - for Australian-profile hardware.
The cylinder suits all common door types and is engineered for greater attack resistance while remaining lightweight and robust.
Frequently Asked Questions
Access rights are written to the user credential and refresh as cards pass online update points or wall updaters. The doors themselves stay unwired - the card carries the update to the cylinder, which keeps permissions current without networking every opening.
Yes - this cylinder can take the SMARTair BLE module to enable Openow, or you can choose the UOC + Openow model with mobile access included from day one.
This cylinder reads HID iCLASS credentials, so it suits sites already standardised on iCLASS. The reader technology must match the credential platform in use - if your site runs MIFARE or another technology, talk to us before ordering. Our access methods chapter explains the credential technologies.
The cylinder is made in Din Double, Din Double thumbturn, Din Half, Din Oval and Australian Din Oval profiles - confirm which profile your door hardware uses before ordering (see Cylinder Profiles above). The door type guide helps you check your door.
This model is rated IP55. Note the rating varies across the range - Standalone and Wireless Online cylinders are IP56, while the Update-on-Card tiers are IP55 - so check the comparison table if you are ordering several tiers.
Additional Information
Standalone and Wireless Online models are IP56; the Update-on-Card tiers are IP55. Check the IP Rating column in the model comparison table before specifying a mixed-tier site.
Because the electronics live in the cylinder, the existing lock body can often stay in place and nothing is drilled or cabled through the door. Lost credentials are cancelled digitally rather than rekeying. Browse the full range of cylinders and barrels for smart locks.
Physical credentials are written with the SMARTair USB encoder and doors are commissioned with the portable programmer under the TS1000 software.
SMARTair is a managed access control platform, and cylinder profile, door condition and commissioning all affect the result. See our advice and installation page, or read about site surveys and installation on the Gold Coast.
This cylinder usually ships in 30-35 business days. Order early for time-critical projects, and confirm the profile and tier before ordering.

Deeper questions and answers for the SMARTair knob cylinder range. For platform-wide questions see the Smart Lock FAQ chapter and the Smart Lock Buyers Guide.
Choosing a SMARTair Management Tier
It depends on how often access rights change and how quickly changes must reach the door. Standalone is programmed at each cylinder and suits small, simple sites. Update-on-Card carries rights on the credential, refreshed at update points - strong control without networking every door. Wireless Online adds live, real-time updates and monitoring through communication hubs. Openow adds smartphone keys to the UOC and Wireless tiers. This page is the Update-on-Card cylinder; the model comparison table on the main description links every tier in the family.
They solve different problems. Wireless Online is system architecture - the cylinder talks to the management software in real time through wireless hubs. Openow is a credential - the smartphone acts as a secure digital key over Bluetooth Low Energy. A SMARTair product can support one, both or neither depending on the model: Wireless Online is the infrastructure, Openow is the way a user opens the door.
Yes. This Update-on-Card cylinder can take the SMARTair BLE module to enable Openow, or you can specify the UOC + Openow model with mobile access included from day one.
Credentials and Smartphone Access
They are different RFID credential technologies used in commercial access control. MIFARE is widely used across many access systems; HID iCLASS is common in enterprise and institutional systems built around HID credentials. The reader must match the credential platform already on site - this cylinder reads HID iCLASS, so if your building runs on another technology, talk to us before ordering.
Physical iCLASS credentials are written with the SMARTair USB encoder and managed through the TS1000 software. A lost card is cancelled digitally - no locksmith visit, no rekeying, and the cylinder stops accepting that credential.
Fitting and Installation
The one your existing hardware uses. The range covers Din Double (credential both sides), Din Double thumbturn (credential outside, thumbturn inside), Din Half (single-sided), Din Oval and Australian Din Oval profiles. If you are not sure which profile your door has, send us a photo of the door edge and the existing cylinder before ordering.
No. The electronics and battery live in the cylinder itself, so the door is not cabled and the existing lock body can often stay in place. That is the core retrofit advantage of the format - see the door type guide for checking your door.
A locksmith or access control installer familiar with SMARTair. Cylinder profile, door condition and commissioning against the management system all affect the result - see our advice and installation page or read about site surveys on the Gold Coast. The installation and troubleshooting chapter covers common issues.
Managing the System
The TS1000 management software (with a web manager option) is the platform hub - it manages users, credentials, schedules and doors across every SMARTair device type, from this knob cylinder to i-max escutcheons, wall readers and i-gate padlocks.
Yes. Openings and credential activity are available through the SMARTair software platform, which is one of the main reasons sites step up from mechanical keys - you can see who opened what, and when.
Cancel it in the software and issue a replacement - the lost card stops working and there is no rekeying. How fast the cancellation reaches the door depends on the tier: immediately on Wireless Online, at the next update point on Update-on-Card, and at the cylinder on Standalone.
