I have a few Opel/vauxhall keys (Delphi, valeo and Siemens types) that I want to renew. I got the Xhorse vvdi prog programmer. Where do i get the renew files?
Free download GM renew files.
Different number key does not matter if its another number the file is the same.
OBDSTAR supports some of Opel key unlock as well.
I’ve renewed 5-6 Opel keys (Corsa D, Astra H, Zafira B..) with Obdstar x300 dp plus, surprisingly it works perfect.

There is no best tool for Opel key renewal. Try it with vvdi, mk3, abrites, keydiy kd, Barracuda. plenty of other tools supports this.
