I just picked up a 09 RT Monday, I discovered this morning when I grabbed 1 and went out to start:

it unlocks and locks the doors, it does not recognize that fob when you go to start. it says does recognize fob on the screen below speedo.

the remote start works, all functions work but cant start car once seated???

as long as I have you here why does the 12 volt (cigarette liter) accessory door/cover have a key pictured on it?

is there a ignitions switch for the key to go in? I cant find one.

I hope I am in the correct area here for this question.

Thanks!

I moved your question to the Electrial Questions and Problems. It may be better suited there.

The accessory plug with the key logo means the ignition has to be in the run position, or the engine running, to provide power to the plug. There should be a fuse in the trunk fusebox that can be moved to make the plug hot all the time.

FOBIK questions and operations

I just picked up a 09 RT Monday, I discovered this morning when I grabbed 1 and went out to start:

it unlocks and locks the doors, it does not recognize that fob when you go to start. it says does recognize fob on the screen below speedo.

the remote start works, all functions work but cant start car once seated???

OK UB,

Most of your questions can be answered by the owners manual, and it may
take you sometime to familiarize yourself with the wealth of info there.

To cut to the chase, you can look at this link below off of the Top Challenger Tips'n Tricks info site.

Keyless Entry System Exposed

Now, the FOBIK that has the issue, can be simply a weak or dead battery.

A common issue. But, you can simply REMOVE the START button by a
slight pressure (like using a small flat tip screwdriver) or the valet key at
six o'clock and the button (cover) will pop out exposing a slotted hole.
This plastic cover, is simply that, a plastic hole cover.

You insert the FOBIK's small flat end into the open hole and use it just like a key.

The WIN module (Ignition switch) will power the FOBIK even if the battery
is totally dead. It should work fine there. If not, you have an issue with
the FOBIK itself, and it won't be due to battery power. If the FOBIK does
start the vehicle, then immediately change the battery out (CR2032) and
instructions on how to do this is on the link above and in your owners manual.

The power port on the dash is technically not a cigarette lighter but a
source of "switched" 12VDC power. It will remain powered for about 2
hours after the ignition is turned off. The main 12VDC POWER port is inside
the front bottom of the center console. This remains powered at all times.

Keep in mind that your FOBIK (transponder) operates on -3- different frequencies
for operations of remote start, lock/unlock and starting the engine/ignition sequence.

Again, Welcome to ForumZ.

From my experience, removing the battery from the fob and then putting it back in helps often. If you have a volt meter, test the battery. It should read 3 volts or higher for optimum performance.

I would replace the fob batteries before doing anything. Don't bother to test them, even if they test good, they may be too low to reliably operate the keyless go function.

Does the dash display say "fob not detected" or "Damaged fob"?

well the new battery didn't fix it.
I haven't had much time between working washing and driving this car.

like I said everything on the fob works, doors, truck, auto start, and it will start the car as a key. once in the car it displays:

fob not detected (when you push the start button)

I'll do some more reading and program it.

Thanks for the wealth of information!

Then it could be several things-
It was working at one time and failed.
It was a replacement fob and didn't have the keyless go function in it and could not be programmed. I bought one like this.
It was the correct replacement fob and was not programmed correctly.
It was the correct replacement fob and was the third fob and could not be programmed for the keyless go function. (I was told and read that you could have several fobs programmed to the vehicle but only the first 2 could be programmed for keyless go, in other words only 2 working keyless go fobs at a time - I'm not 100% sure on this.)

the key was bad.

I took it back a couple weeks ago so the could re-program it, during the programming proses the computer said the key was bad so they ordered me a new one and gave it to me for free!

Glad to see it was resolved. Keep a spare battery with you. You never know when you will need it.

Good idea.
There is a dollar store or drug store every square mile here in Michigan if I need one.
It's a common battery.
