05 cobalt alarm when remote starting

I just finished in stalling a Viper 5501 remote start with a XK01 interface module in my wife's 05 Cobalt with factory alarm. My problem is this, when remote start is activated everything comes on for a second then the car begins to crank and the alarm goes off for a second. The car starts and everything works as it should, its just the alarm gets activated for a second......any ideas? Thanks in advance for your help, I appreciate it!

well i hope someone replies i installed a ultrastart3280 today and my online diagrams are not very accurate and i have a similar problem when locked with factory key fob the car wont start it's a 06 cobalt and the by pass is an expresskit dlpk i couldn't get it to run unles you remote start before security light goes to blink mode and i know its' got something todo with the immobillizer i need some help too pleasewiringfool eieioztztzt

I dont think the DLPK does immobilizer bypass on your car, I know it says it does in the description,but you need another piece to do RF transponder overide......I think its the 556U. you have to loop an antenna over your ignition cylinder and run it to the module....or you may be able to just run the antenna loop to the DLPK. check www.bypassskits.com, select the DLPK, click Vehicles and Functions, and it will tell you what firmware is needed for your car and which operations it will cover.

heres the scoop on this problem today i called for help and got some extra info reprogramed with accy. for 1 sec. on ign. 1sec than apply brakes put in rev turn to start position for 1 sec. not to sure that this was correct but i did locate one connector just alittle cook eyed and i had the module tied agasnt the steel sub structure i feel that the steel caused some problem with the rfi and works great now thanks for the input hope i  can help someone with there problems in the future these are just machines and we are the brainswiringfool eieioztztzt

guess what didn't get it tech support also didn't think it does the transponder but i mentioned the web states it does they told me possible corupt data output well i took module out after located no accy output voltage and dont have another its friday the thirteenth guess i should have known' on another vehicle it had to test my brain but i record voltages and other special things of new vehicles for record guess what i found on new 09 ford problem. darn i'm not perfect cold solder joint on tx data wire found by discrepency of the voltage record or i would have never been able to decipher the problem loked like faulty module but what comes in must go out kinda funny ain't it sounds like the toilet ha hawiringfool eieioztztzt
