TECH-TIPS # 29 – 2008 CHALLENGER / KEYLESS GO BUTTON OPERATION AND POSSIBLE
BATTERY DISCHARGE
DISCUSSION:
If equipped, the Challenger is shipped with a Keyless GO Button in the vehicle’s glove box. This feature, if
the customer chooses to have it installed, will allow the driver to operate the ignition switch without the need
to physically install the FOBIK into the ignition switch. The GO Button is packaged in a plastic bag with an
instruction card. The instruction card explains how to operate the GO Button once it has been installed to the
ignition switch. The instruction card should be reviewed with the customer during vehicle delivery and then
placed into the owner’s manual for future reference. With the GO Button installed into the ignition switch and
the FOBIK in the vehicle interior, the GO Button (like the FOBIK it substitutes) will allow one or more of the
following ignition switch modes. With the brake pedal not depressed (foot off brake pedal) the following
ignition switch modes can occur: accessory, run, and off. With the brake pedal depressed the following
ignition switch modes can occur: start-run, and off.
NOTE: INFORM THE CUSTOMER THE BATTERY IS DISCHARGING WHENEVER THE KEYLESS
GO BUTTON FEATURE IS IN EITHER THE “ACCESSORY” OR THE “RUN” MODE. THE
“ACCESSORY” OR “RUN” MODE WILL REMAIN ACTIVE UNTIL THE “OFF” MODE IS
SELECTED OR UNTIL THE VEHICLE ENGINE IS STARTED. IF THE DEALER OR VEHICLE
OWNER FAILS TO ACTIVATE THE “OFF” MODE, AND EXITS / LEAVES THE VEHICLE
WITH THE FOBIK, THEN THE “ACCESSORY” OR “RUN” MODE WILL STILL BE ACTIVE
AND MAY COMPLETELY DISCHARGE THE VEHICLE BATTERY.

TO INSTALL THE KEYLESS GO BUTTON FOLLOW THESE STEPS:
1. Remove the GO Button package from the vehicle glove box.
2. Position the lettering on the GO Button so that it is horizontal and readable. The GO Button has the
words “ENGINE START / STOP” on the face of the button.
3. Gently insert the GO Button into the ignition switch receptacle by pressing on the center of the button.
4. If the button slips in easily, then it has been installed correctly.
5. Press firmly on the center of the GO Button to seat the button into the ignition switch receptacle. The
Keyless GO Button can be removed at any time. Remove the GO Button if the use of the FOBIK is
desired to operate the ignition switch (instead of the GO Button).

TO REMOVE THE KEYLESS GO BUTTON FOLLOW THESE STEPS

1. The GO Button may be removed using the valet key from the FOBIK as a thin tool.

2. Insert the metal part of the valet key under the chrome bezel at the 6 o’clock position.

3. Gently pry the GO Button from the ignition switch.

THE KEYLESS GO BUTTON (ENGINE START / STOP) FUNCTIONS

With the driver’s foot OFF of the brake pedal, transmission selector in the PARK position and the FOBIK

must be in the passenger compartment of the vehicle:

1. Press the ENGINE START / STOP button once to activate the ACCESSORY mode which will allow

operation of the radio, wipers, and windows.
2. Press the ENGINE START / STOP button a second time to activate the RUN mode which will allow the
operation of the heating / air conditioning (HVAC) controls, and the instrument cluster.

3. Press the ENGINE START / STOP button a third time to activate the OFF mode

With the driver’s foot ON the brake pedal (brake pedal depressed), transmission selector in the PARK (or

NEUTRAL) position, and the FOBIK must be in the passenger compartment of the vehicle:

1. Press the ENGINE START / STOP button once to activate the START-RUN mode. The engine will start.
2. Press the ENGINE START /STOP button a second time to activate the OFF mode. The engine will stop.

NORMAL STARTING

To start the engine, the transmission must be in PARK or NEUTRAL, and the FOBIK must be in the

passenger compartment of the vehicle. Press and hold the brake pedal while pressing the ENGINE START /

STOP button once. The system (TIP START feature) takes over and attempts to start the vehicle engine. If

the vehicle engine fails to start, the starter will disengage automatically after ten (10) seconds. If you wish to
stop the cranking of the engine prior to the engine starting (within ten seconds) then press the ENGINE

START / STOP button again.

Quick question: If you took the button out of the challenger and placed it in a Charger/300 with the FOBIK ignition, would this work the same?

no idea. never tried it. i would think that the WIN (wireless ignition node), the part that the FOBIK slides into would be different, if only in programming.

give it a try and let us know.

**ZeGuru** · 09-14-2008, 10:16 PM

I'll have to swing by the dealership and test it out. I've just been curious to know if it would work.

**SRT-ED** · 09-14-2008, 11:53 PM

Keyless go is the best feature ever... I have it in my wife'w E-class. There have been plenty of times where I have got upto the door of the maggie and pulled on it and its still locked...

**mebe** · 10-17-2008, 08:45 PM

i tried it its a no go.. Do they have to be programmed??
I do only have a 08 touring now so i dont know if that is an issue, but i do have the fobik key.. When i put it in and push the button it the car dinges and the little security light comes on notheing else though.

Any ideas?

**mebe** · 10-22-2008, 01:49 PM

Anybody else have any info on this at all?? fnky??

**ZMagnum** · 10-22-2008, 03:09 PM

It won't work in an 08 not equiped with keyless-go. I spoke with a Mercedes mechanic about it a while ago.

**mebe** · 10-22-2008, 05:28 PM

thank you sir!!

**BAKBRNR** · 10-24-2008, 01:45 PM

This would make a nice mod for the 08s if they could be converted. I wonder what it would take to make it work?

**rxnick81** · 02-21-2009, 04:06 PM

Had my 09 srt8 challenger at the dealer today for the 2nd time. The dash msg center keeps saying the key is damaged and the car will not auto start. Apparently, there is a known issue with the key fobs. Don't let your dealer make you wait around the service area for 2 hours only to find out they need to new keys and rematch them to the car, like I did!

Can this be put into an '08 300 or Charger...?

YES, it can be done for 2008-2009 300C/300CSRT's

It involves purchasing a new WIN module, new Chrysler key fobs (4-button or the 5-button with remote start), a Passive Entry Module, start button, and a couple of Chrysler low frequency antennas. A little wiring is involved. One antenna is installed under the rear seat with a pair of wires running to the dash behind the glove box. At that location the second antenna is installed and wired to the Passive module. The Passive module needs to be wired to the CaN Bus (+ and -), and also to power and ground. To make it all work, a dealer has to do some programming for the new Fobik's, and Passive module. You might be looking at $500-$600 in parts alone...

Thanks to RESUME SPEED for the above information.
