I'm trying to code a new remote key's immobiliser chip into my car's ECU. I'm following the instructions in the handbook. It's not working.
Do I just keep trying, until I get the timings exactly right?
Or, is the new chip the wrong type? My existing blue coded key has a carbon ID4D chip. The new key has an AB suffix and a glass chip, which should be an ID4C chip.
Do I need to get an AC or AD key with a glass ID4D chip?
However, I have seen an AA key, which should have an ID4C chip, and an AC key, which should have an ID4D chip, in use on the same car.
