Will VVDI Key Tool Plus do Renault Clio IV or Clio V

Will Xhorse vvdi key tool plus program Renault Clio V (i.e 2020 Clio 5) or Clio IV key? add key and all keys lost?

This is a frequently asked question.

No, Xhorse only does Renault Clio till year 2012. So it cannot do Clio 4/Clio 5 at present.

Xhorse released a groundbreaking update in 2024.  Xhorse VVDI Key Tool Max Pro received this update too.

The update is very good and tested working by many users.

We did 2014 Renault Master today with Xhorse Key Tool Plus. all keys lost. 30 second job. Easy.

One of our customers have completed the card smart key programming of Renault Talisman 2019 and Megane IV 2018 using new software patch and everything OK. It does not read the EEPROM. Seems safe and takes only about 3 minutes to make a dealer key and about 2 minutes to program keys in.

It does do some Renaults, but it does not support Clio V, Clio IV, Master 3, Duster PH3 etc.

Waiting for feature updates.
