2002 Tundra Factory Alarm Arm?

Did Remote Start and Keyless entry on customer's vehicle today, now customer is angry because he wants his FACTORY security to arm and disarm with his new keyless or he will have it all removed. DEI shows a factory alarm disarm (blue/black in driver's door harness) but no arm wire. Any suggestions??? John

i would guess the arm wire is there too. use the factory remote to see if it is arm with remote only or can you arm with the key in the door, if you can arm withe the key there has to be a wier some where in there. but i would call tech support to see if thay have any more info on this. let me know if i can help any morebring back the rotary phone so i dont have to press 1 to proceed in english
