Valet 561/562 Lights Flash, No Lock or Unlock or Start

first post here , used the site for tips dozens of times over the years on audio , but alarms I am clueless on.    I have a viper 5706v I pulled from my 2012 pilot when I got rid of it. I bought a 05 trailblazer ext to use for work , i went to the local shop i used , he said $200 just to install the viper , i don't have the cash to waste right now and im ok with the valet brand remote start but now its December and it stopped working.   typical luck      the lights flash when i hit lock / unlock , but nothing happens , same with remote start.   i don't know where to start looking but i hate a 20* car at 530 am !        sitting in the car i hear no relay clicking when i try the lock , possible fuse somewhere ? any help is extremely helpful

also if I start the car and hit the remote start button while engine is on it will work normal so I can take my key out and run into a store , so i am guessing the tach is wired / programmed corrrectly and what ever bypass i have , otherwise it wouldnt run while in teh store???

Have you contacted the dealer about fixing it?My ex once told me I have a perfect face for radio.

I don't know where it was installed , its an 05 that I bought used a year ago   , also I made a typo , I DO hear the relay click while sitting in the car

look under the dash, and see if the toggle switch is "off" or broken.

there is no toggle switch that I can see , it was working one day then stopped the next.   I will look more later today , in "off" I assume you mean it would be in a valet mode ?   if so wouldn't the door still lock if I press the remote ?
