How do i know if its my remote key that wont unlock the immobilization.
Is there a way to test key before replacing back com and fob..i have an obd 11 scan tool just comes up with errors. I have done pin 5 and 6 to test and fixed 2 problems on car.. still the immobilized won't stop flashing.. I can start the car although f I leave ignition on for 2 hours. Car runs fine.. any other suggestions before i change more parts

If it's a V6 they use ALDL, not OBDII so your scan tool won't work.

What errors are you getting? Have you replaced the key already? First place I'd look is the metal ring around the ignition barrel. You may need to pry it it up slightly to make sure it's making good contact with the metal dot to the side of the blade on the key.

I've changed that also made the contacts better. Have two remote keys checked battery voltage and both are close to full charge. Changed steering lock as well..looked at all fuses and solenoids i changed them from another car that has no issues

12 is all clear. Do the doors lock and unlock remotely with the keys? Does it crank or just do nothing when you turn the key?

Did you change anything around the time this started happening? Memcal, ECU etc...

does remote work to unlock doors, did it work prior to this fault
if it does work, press unlock immediately before attempting to start
unlikely to be bcm, they are pretty reliable
more likely to be remote
where in melb are you as quite a few around here have tech 2

Doors won't lock or unlock via remote..it stopped opening doors about a few weeks prior to this happening..
engine light started coming on after 30minutes into a drive everyday car ran fine though..
battery died on the occasion when it stopped starting after my drive to work.
car cranks to almost starting but won't because of the immobilizer .thermo fan will come on after cranking but not starting though

Does central locking work? Leaning far towards the key.
