can a key be traced as being used last to start the engine
time and key?

Answer......yes.

If its an RFID key the rolling code changes each times its used. The ECU can be interegated and the time period between code changes can be extracted with specialist equipement, assuming of course the ECU and its internal battery is servicable. Of course on an older model such as the Corsa in question it doesnt give the exact time in a GMT style format but with some careful calculations you can get it to within an hour or so on a particular date.

>Instead of putting up smart-alec comments about totally unrelated cars, it you'd had a look in one of the other sections you'd have seen that the OP asked the same question - but mentioned specifically that it was for a Corsa 'B'. Now, those stopped being made in 2000, when (I believe) even BMW were not using that sort of tech on their cars, unless in the 7 series. So to compare the 1993-2000 Corsa to the 1-series (introduced in 2004) is more than a little bit disingenuous.

Except that in one of the at least four other threads started on the same topic, the OP says it is a 2013 model. Was there ever an urban myth about the Corsa B?
