99 navigator remote start w/ 555p

hey guys, i need some help with this install. i installed an autopage 850lcd remote start in  a 99 navigator, only problem is that the remote start won't go. alarm works fine and the engine cranks but no ignition. i was told by dei that the 555p would work for the pats bypass but i still can't get it to turn on. the led turns on , on the 555p telling me that it is emitting a code but still no ignition. it says that i need to program 2 keys into the 555p but the customer only has one, would that be why? just looking for some confirmation on this, and any advice you can offer. thanks in advance.mark brasil, alpine 9811, ppi 6600 6ch amp, planet audio comp. set(2), custom built slot portbox,3-4yr old audiobahn alum q 10",ppi 1000 watt amp, 04 scion xa
