Successfully Enabled OEM Remote Start

[hrdfsique]

"Key Fob not detected." Then, "Push Button with Key Fob to Start."

The Docs say that the original Fobs should still work; they do not.

Anybody hit this issue?

Just swapped the old unit back in. No issues. Hmmm.

Hood ajar and tailgate ajar indicators work. That's cool.

Did a key program with Jscan and tested remote start with old hub. No go. Didn't think it work anyway.

Just went through attempting doing hub reset / replace using both alphaobd and jscan. Neither works. Have to be able to enter vehicle in Run mode to get code. Can't do it without programming keys to new hub.... Infinite loop of death.

Latest update:

As mentioned above, I programmed a key to the old RF hub just to test. It does start remotely only by installing the hood latch, using the old RF hub without antenna, and programming BCM for remote start. I can confirm that you do need to drive the truck... I read in OEM docs over 10 mph; I read in these threads over 30. I did go over 30.

So, what in the world is the new RF Hub with antenna for? App Start? I spent $300 for something I could have done with a $0.10 resistor and $40 key.

The only way to get that new hub to work is take it to service dept. Can someone explain to me the benefit of the antenna?

What are the options if any for a 2024 2500 that does not appear to have the hood latch connector.

What are the options if any for a 2024 2500 that does not appear to have the hood latch connector.

You'll have to check the BCM harness to see if there is a purple wire on pin 11 in the upper left plug (not sure if it's the same on 2500s, I have a 1500) - that is the hood latch sensor wire.

If you have it, you will just need:

• T-Tap or a traditional in-line splicer,
• 18GA wire,
• a crimp kit with an O style end that you can crimp to the 18GA

and then ground it to something.

Note: there is a good chance the anti-theft is expecting a 1k ohm resistance on the wire you ground, you can find those on amazon as well.

What this does is essentially tell your BCM that your hood is closed, even if it is open. Be very careful if someone or something is in the engine bay and your kid decides to start your truck. It could be deadly.

If you have push button start AND the hood latch connector (you’ll have a light on your dash if your hood is open if so), you already have factory remote start. You simply need to turn the function on via AlfaOBD AND have a new key fob programmed to your truck that has the remote start button.

Can we program the fobs ourselves? My 22 has this on it but when I try to pull the pin it's saying it's not supported on alfaobd

No, you can not use Alfaobd to program fobs. Have to use the dealer or a good locksmith. Or buy the real expensive programmer yourself

Use JScan instead if you want to pull the PIN and program fobs.

Does this hold true for 2500s? I would like to add remote start but I do not see any 2500s in this thread

Idk...Jimmy07 may know.

Would this be a better option than running a new hood latch and "re-wiring" the BCM harness?
