Infiniti Repair Questions? Ask a Mechanic for Answers ASAP
to have no power at all then it must be a poor connection on the high power side
I'd check over the state of the high power (25A+) fuses in the underhood fusebox check for cracks and corroded sockets and then do the same for the ECU and ignition relays
ideally use a voltmeter to try and confirm if you have 12V going to these fuses with the ignition on
and yes there's a chip inside the key that is picked up by the antenna inside the column to disable the security
but from your description I don't think its a security issue
do you still need help?
