double pulse remote start problem

Vehicle - 2008 Ford Fusion

Hello,

Just installed a DEI/AutoCommand 25622 stand alone OEM remote start. The activation input requires a single or double negative pulse to activate the start sequence. The Ford factory door locks apparently are set for a double pulse, which means everytime we lock the doors the car starts; real pain.

Is there anything I can do to resolve this issue? The remote starter is mostly useless at this point.

Thanks for the help.

My unit can only be programmed for one or two pulses, pretty basic DEI unit. I called DEI and the tech. said some newer cars are coming with a double pulse from the factory. I can confirm this this because the remote starter starts when I touch the activation wire to ground twice, or hit the lock button once in the car.  So I can eliminate there being an issue except this double pulse dilemma.

I also considered using a negative pulse from the trunk pop since I have that button on my factory remote, but I can't seem to get that to work for some reason. I am truly open to suggestions on this.

Relay wasn't needed, just used door lock motor negative for input.
