KESS3 Subscription Renewal

Alientech Kess3 Subscription Renewal

Renew for 6 or 12 months

Keep your Alientech KESS3 Master or Slave tool fully supported with an official subscription renewal. The KESS3 requires an active subscription to receive software updates, protocol releases, online services and technical support, all of which ensure your tuning workflow stays current, efficient and scalable for your business or workshop.  

Choose either a 6-month or 12-month renewal depending on your needs. Renewing proactively means uninterrupted access to new vehicle protocols and improvements as they’re released. Even if your subscription has lapsed, we can help you reactivate it. 

You can only purchase your subscription renewal from VIEZU if your Alientech KESS3 tool was purchased through us. Otherwise, renewals must be purchased directly from your tool’s Master. 

If your subscription is more than 60 days out of subscription you will need to purchase a KESS3 Subscription Realignment Fee in addition to your subscription renewal. 

Why Renew Your Subscription? 

• Latest protocol updates – stay ahead with support for new vehicles and features.  

• Technical support & tuning files – access professional help and ready-built tuning resources from the VIEZU team.  

• Online services remain active – including web services and tool management.  

• Flexible durations – choose what fits your schedule and workload.  

How it works:

Select your activation type (Master or Slave) and subscription length, then complete checkout to renew. With a valid subscription, your KESS3 keeps delivering full functionality – no features missed, no interruptions to tuning work. 

Advantage of a KESS3 Slave Tuning Tool 

One of the advantages of a slave tuning tool from VIEZU is that ready-to-use tuning files with backup and support are available without the need for technical file writing knowledge. Alientech KESS3 slave tuning files will be provided by a master tuning file provider – typically, VIEZU provides these files. The technical support team is ready to assist you. Tuning support from VIEZU will include ECU and TCM remapping and tuning files, training and support for your business. VIEZU tuning files are fast, reliable, and custom. 

We offer free training and support seven days a week. Find out more about VIEZU dealer support here: Become a Dealer 

Advantage of a KESS3 Master Tuning Tool 

Master tuning tools are usually for those who wish to purchase tuning and remapping files from several tuning file providers, as well as tuners who wish to write their own tuning files. 

There is no commitment if you do not want to be part of the VIEZU dealer network. If you have a tuning file provider, simply purchase your new KESS3 tuning tool from the VIEZU shop, add the protocols you want and let us know which master tuner you would like to use, and we’ll do the rest.
