Here is the customer solution to Opel Insignia 2011 all key lost.
I am trying to make key for Opel Insignia 2011 with 7936 and FVDI via ODB but don’t know if i have to precode the transponder or have to make it with blank 7936. I tried with effi (173) writing the key into dump from BCM 24c16, but no success, effi don’t work and lock transponder.
It is the first time that i making on Insignia and it is not very clear the way how to make it.
For all who have trouble whith this car and do not have dealer key,you can make it to start with 7936,of course without remote,with the great assistance of a mhhauto member.
1.read bcm 24c16
2.prepare transponder whith effi 173 module(mine is not original and the file created with effi is empty,therefore you have to make it manually)transponder is ready to start the car,but you have one step more…
3.write the ID of transponder and number of keys in the correct place of dump
4.put the bcm in car
5.start the car
