Hello my name is ***** ***** thank you for your question.

When you are programming keys you need to turn the Hazard lights on to wake up the BCM. Other wise, you have 3 wires to the OBD2 connector that supply power. Which I believe only 2 will supply power when the ignition is off. When the key is ON, then 3 will have power.

Does he have a volt meter or test light to check the obd2 port for power?

turn on hazards still no power

He's making the key, so we can put acc mode now

Do you have a Intelligent key type of ignition?

Customer: replied 7 months ago.
we just hoping putting car ignition in acc mode will provide power to obd-II port
Customer: replied 7 months ago.
Then he can program chip and fob, if we get power
Expert:  Jay replied 7 months ago.

You have to program the mechanical key first before you do the remotes.

Does the OBD-II have power without being in acc mode?
Expert:  Jay replied 7 months ago.

No, you won't have all the power you need at the OBD2 port if the ignition is not on. You need to put the hazards on, and perform steering lock release so the ignition can be turned on to program the keys. Then once the keys are programmed, then you can program remotes.

How do I perform steering wheel lock release?
Expert:  Jay replied 7 months ago.

With the proper scanner.

Customer: replied 7 months ago.
Ok, should he have that?
Expert:  Jay replied 7 months ago.

I don't know who he is? Is he a mobile tech? Mobile Locksmith?

Expert:  Jay replied 7 months ago.

Also make sure the battery is fully charged. That can also affect the turning of the key in the ignition.

he's a license/bonded automotive locksmith...I am paying the company a lot money
Expert:  Jay replied 7 months ago.

Well, I would have him double check all fuses first. Also make sure there is two power sources at the OBD2 port with the key off.
