2008-2011 Crown Vic Remote Keyless Enable/Disable

Post by ThatOneDude » Tue Jul 11, 2017 1:05 am

I have identified the bit to enable and disable the Remote Keyless Entry feature on 2008-2011 Crown Victorias (I have not tested on older vehicles). All of the 2008 to 2011 vehicles have the hardware to support RKE, but it has been disabled in some by the factory.

In DDM A0-08, the first two bytes can be represented in binary form as 0000 0000 0000 0000. With Remote Keyless Entry, the following change is made to the data 0000 0001 0000 0000.
(In this case, 0 is unchanged, 1 is changed)

This could be added to the human readable configuration page to make the process easier for other users who are trying to enable RKE on their vehicles.

Thanks for sharing, I am working on decoding the modules on the 08-11 cars myself, I hope to be able to share some of it soon. The DDM seems to have the most settings outside of the engine computer.

You are saying Keyless entry, do you mean turning on the wireless Fob or the door keypad?

Curious, all the as built data I have, various market Crown Victoria's, Grand Marquis's and Town Cars none of them have that particular bit turned on? 0000 0001 0000 0000

It may apply to 06 and 07 cars with a DDM, not all cars had them, there were changes for the 08 and up cars when they added tire pressure monitoring.

I don't have a keypad, so I can't test whether it is enabled unfortunately. But this did enable the remote keyless for me.

Disreguard my last post, must remember not to post late at night when having a migraine....

That does correspond with what I know of A0-08, was it you that shared when you enabled 0000 0000 1000 0000 that you got a flashing TPSM light? I have been wondering about the spare tire PID, there is a location to store a pressure for your spare and I know as it stands you only program 4 tires, not the 5th-spare.

Maybe it's for that or perhaps extra code for dually trucks with 6 tires?

Sounds like it's time for some experimentation...

I shared on CrownVic.net while I was still figuring it out. The bit that triggered my TPMS flashing was 0000 0000 0100 0000.

So if im reading this correctly,
A0-08 2815 d600 00BB
should be changed to
A0-08 2811 d600 00BB
to turn on RKE?

Im new to forscan and still learning

You have to convert your hex to binary to use the above change. We'll focus on just the first part since it's the important part.
0010 1000 0001 0101 = 2815
We need that to be changed to the following.
0010 1001 0001 0101 = 2915
That makes your final result 2915 D600 (leave last part for FS to calculate)
