Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
Sounds like you have a key or key reader issue.
Quite common with VZ.
I would get a scan done on the vehicle, Supercheap Auto can do this for you for $14.
It will have codes in the BCM and PCM.
When you get the scan done, can you give me the codes?
I hope my advice has been of assistance to you.
