HELP!! AC and Radio not working. Car will not start!!

So I have a 2010 Gen Coupe 3.8 with push start automatic transmission. Mirabeau blue. H vin.

I have replaced:
ECU
BCM
PDM
Smart key
Key Control Module
Fuse box
Main relay
Main relay box
Push button

I lost power to all accessories.
The ac and radio do not turn on.
The push button blinks red 5 times even after I swapped the parts.
I checked the memory fuse and it is good.

I took the car to an automotive electrician and he said all of the grounds were good. He even replaced one ignition relay which didn't change the outcome.

Does anyone have a solution to this?

I was thinking maybe it's the radio??? I am not sure. Please help. I don't ever ask for help but here I am. Any knowledge of the problem would help.

Ummm, unless all the computers match the key, the car isn't going to start.

Maybe you shouldn't work on the car until you read a service manual

I took it to Hyundai and they told me they won't look at it unless I buy a brand new key module and fob through them. After install and everything it would be like 1400 and I'm not paying that.

Find another dealer who wants to actually help a customer.

You might also contact a locksmith that specializes in autos. Sometimes they can do the programming.

I've already looked into a lock Smith here and they couldn't do anything. And the ones I call tell me to take it to Hyundai because no one wants to deal with it.

I don't blame the dealer in this case. I wouldn't what to be liable for fixing something that someone else replaced a bunch of parts on either, especially when dealing with all the car's computers.

You can get the Hyundai GDS software and hardware with files off ebay for ~$240. It can do all the investigation for you that the dealer can.

AKGC if you aren't gonna contribute positively then don't reply at all. Not everyone can afford the rediculous bills hyundai wants to charge for.

If anything my comments were neutral.
Most people would try to diagnose a problem and research procedures before throwing money at it, instead of making assumptions and changing parts, willy nilly.

AC won't work - reason, engine spinning is what runs the AC pump

Radio - the immobilizer won't let the car go into accessory mode, because none of the security checks, match.

I would put in the original computers and pull OBD codes to see what's really causing the issue, if you can even get the car to go into accessory mode.

You say you replaced the smart key? Did you get it reprogrammed?

Have you checked the fob's battery? Then inserted it into the slot? Then held down the start button for a few seconds, 5?
Have you tried inserting the key into the slot?
Have you checked the brake switch?

The blinking light is a fob communication problem. So something to do with the ignition lock.
