2004 grand prix gtp

I have a Viper 5501 installed in my 04 Grand Prix GTP. I am using a XK09 module to do the door locks/trunk pop and PK3 bypass. Door locks, trunk pop, light flashes work. Remote starting works when I put the key in the ignition, but it won't start without the key in the ignition. When I try to start without the key, the doors unlock, lock as soon as ignition activates then the car displays "Starting disabled due to theft system" and the doors lock. The only setup instructions listed were to connect D2D wire first, then 20 Pin wire harness. Then connect keyless data wires to ground until the light came on XK09. I did that, light came on the XK09 but still no PK3 bypass action going on. Are there any other programming steps? Am I missing something? Thanks in advance all!

Might have some bad news for you.  The DEI XK09 flashed with the 9.DLGM5X firmware is a "Doorlock"module only.  It does not handle the PK3 transponder bypass.Soldering is fun!

Programming a new transponder key to the G.P.'s PK3 system is real easy.  You can get a un-cut transponder key for $10, program it ( using a R/S ) and place it in a 556UW ($15 ).

Ahh yea...Now that I re-read Xpresskit's site..."OEM Remote Start Activation". Thanks! I'll order a 556UW and a key.

OK, I lied. XK09 only unlocks drivers door, but not the other doors. Like its stuck in 2nd unlock or something. Ideas on that?

Rookie question here: Is it possible to daisy chain the XK09 and the 556UW or do I need to do the 556UW ONLY and hardwire the rest?

Personally, I use iDatalink bypass modules.   For that vehicle, they offer a "combo" module that will handle the

PassKey3 transponder bypass thru data, the locks, alarm, trunk release and supply some alarm status signals.Makes life easy.   Also, I always connect the units in the W2W mode.

I have never used an XK09 for your application, so I can say why it is not controlling the doors properly.  Did you

make the connection to the Keyless Data wire ( BLACK/ White wire at BCM, C1 connector, pin 37 )?

As for multiple modules on the Viper 5501, in W2W mode you can use the Dark Blue (-) Status Output and the

Blue/White (-) 2nd Status Output as GWR for module control.

I did make the keyless data connection. This car hasn't had the factory remote for a long time. Could it be that there is a setting in the car's computer to only unlock the drivers door via the remote? I'll check out that bypass module, combos are good as I don't know where I would put another module. Thanks!

Think that car has "progressive unlock".  Have you tried two unlocks in a row ( within a second of each other )?

As for the iDatalink bypass module, look for an ADS DLSL GM1.  It's a Solo series and should come with the correct firmware pre-loaded.

Soldering is fun!

Yea, I tried to hit unlock twice, just re-unlocks the drivers door.
