[loki954]

but I do not exchange ecu
the car came to me immobile after the customer connected unnamed diagnostics and managed to deactivate the keys and adaptation between the cluster and ecu
I don't know how it's possible
key is learned but engine ecu reports DTC P1570 and doesnt start only two seconds and shutdown

don't think that there is key stored in the IC, have to provide more info about the car and what you need (the entire story)...... we are guessing here !!!
