using ford keypad with dei alarm?

Hello,

I have the Viper 7901 installed in my 06 Ford F150.  It has the factory numeric keypad on the door to unlock the vehicle.  It still works to unlock, but obviously it triggers the door alarm when used while the system is armed.  I am wondering if there is a way to wire it up so that when the factory keypad is used while the alarm is on, it will disarm the alarm before unlocking the vehicle?  Thanks in advance!

So provided the keypad puts out either a ground or positive signal, i would simply tie that to one side of a relay, and either +/- to the other side, then use each side of a spare key fob switch for disarm on the other 2 legs?  Effectivly then the keypad would trigger the relay which would complete the disarm function.  Then I guess to arm it, I would use the other button on the remote and the other leg of the keypad switch.  That make sense..why didn't I think of that.  Not too bad, but I would probably have to take the door panel off to trace the wires unless someone knows if the keypad wires come out of the door before hitting the lock/unlock motors (doubtful).  Thanks.

You're on the right track, it might be an idea to get a DC/DC convertor to drop the vehicl's voltage down to 3v? that the remote uses. Top of my head, ign on and driver's door open or make sure GREEN door switch wire is going to ground, press valet button, releae siren chirp then press and hold pushing the arm button on the remote. That should do it.

I hope this helps.
