03 impala gmdlbp keyless won't work

I have a 2003 Impala base model, and today installed a Crimestopper CS-201x alarm/rs and a Bypasskit GMDL-BP.  I don't need any of the alarm features, so I left out a number of those hookups.  All went well, and everything works except for the keyless entry.  It will not lock or unlock my doors.  The car has factory keyless, so I know that isn't the problem.  I know that the signal is being sent to the bypass, as I can see the LED light when it is supposed to be locking or unlocking the doors.

I have tried Platform Type 1, 2, 3, and 4.  On all types, the car will remote start.  On all types, the keyless will not work.  I have set the bypass options to both Driver Priority and to Unlock all, but no difference.

On the RS, there are 2 plugs that can be used to send the lock/unlock; the blue 4-conductor plug that is designed for external Crimestopper databus doorlock adapters, or the white 3-conductor plug that sends the + or - pulses in normal usage.  I have tried connecting to both of these (not at the same time), and they both cause the bypass to act the same.  It receives the signal from the RS, and the LED lights, but the doors do not respond.

Does anyone know why this is, and has anyone installed one of these on a 2003 Impala base before?

Thanks.

Wow.  Mine DO NOT have that.  On the List of models and years that this will work for, it lists the '03 Impala LS, but then under the Step #1, Vehicle Platform Type Selection mode, it doesn't even list the Impala.  I just went with the same as the Alero, etc. at 2.  All right, I guess I will dish out the $40.00 for the GM-SL2.  Crimestopper's website says this will work.  Are they right?

NowYaKnow, thanks for the quick reply.

GMDL-BP will not do the locks 

I am not an installer, just shadetree stuff here, and I am not finding the ADS-DL anywhere online.  Does anyone have any information on where I could find it?

Thanks.

Dave,

Thanks for the input on the resistor. 

I have seen on this forum where that is the way to do the doorlocks "manually".  I want to do them through the Databus, so I am going to go with the GM-SL2.  I can't find the ADS-DL listed for sale anywhere online, or I may consider it.  I can get the GM-SL2 for $40.00 shipped, so that makes the most sense to me.
