⚠️ Requires an already activated Kess3 Master Alientech device.
This product is a software extension, not a device.



Renewal of the KESS3 Master subscription for 12 months.
The KESS3 subscription provides access to new protocols published by Alientech, the virtual reading service, web services linked to protocol operation and technical support. It is unique and depends only on the device version, not on the vehicle types or communication modes activated.
The Alientech protocol catalogue is regularly updated as new control units enter the market. A device without an active subscription continues to work on already activated protocols but no longer receives new ones.
Renewed during the active period, the subscription switches to the early renewal rate (ref. KESS3MS102), which is more cost-effective. A reactivation option exists for devices whose subscription has already expired.
Pairs well with
Remote activation within 24/48 hours

⚠️ Requires an already activated Kess3 Master Alientech device.
This product is a software extension, not a device.

The price depends on when you renew, not on an additional option: the three plans provide access to the same services once active.
Early renewal
Your subscription is still active. If you renew before it expires: the new period starts on the scheduled expiry date, without losing a single day. This is the cheapest of the three options.
Renewal: this product
Your subscription has just expired, or you are renewing right after. The new 12-month period starts on the renewal date, slightly more expensive than anticipated, as the subscription was no longer active at the time of purchase.
Reactivation
Your subscription has been expired for a while: protocols already activated are still functioning, but the tool no longer receives new protocols, and access to online services and support is suspended. Reactivation restarts a 12-month period and restores these accesses.
The KESS3 subscription provides access to the activation of new protocols published by Alientech, virtual reading services, web services related to protocol operation, and technical support.
Already activated protocols remain functional after expiration, but the tool stops receiving new protocols and access to online services and technical support is suspended.
At or shortly after your subscription expires, before reactivation becomes necessary.
The activation of new Alientech protocols, the virtual reading service, web services related to the operation of the protocols, and technical support.
No, early renewal (€990.00 ex-VAT) remains cheaper as long as your subscription has not expired.
Yes, the same rules apply to a lower Slave rate, only the product reference changes.
