need help with my 2003 anti theft problem.

Tackle

Are we supposed to guess what the problem is?

Are you trying to steal the truck?

Tackle, I was waiting for you to post.

But yes, you need help. What type. What is it doing, not doing, you want it to do. Key fob issue, key issue, ignition switch issue, computer issue, PATS question in general, want to bypass it, want to install an after market alarm, remote start, want to steal a truck with it...

Well cmon meow. Use some common sense. If he'd like help at least tell us the problem. I'm good but I'm not a mind reader.

my truck will only pass anti theft start up if the cab temperature is 85 degrees or higher. i have a ceramic heater in it all the time in case it wont start . plug it in for 20 minutes and away i go. Only use it for recreation so has not been a big deal but transmission just went on my wife's car.
tried a heat gun on keys, steering column and under dash but cant duplicate the 20 minutes of the heater.of course if its a hot sunny day there is no problem either. Anybody seen this before?

Are you positive it's the pats that is the issue? Can you describe what happens?

put either key in when cab temp is cold and theft light flashs . will turn over but not start. Sometimes if you leave key in on position and wait till light stops flashing than pull key out and put back in again it will pass pats and start. Its almost like something electrical or electronic has to heat up before it works properly. I have been living with this for 6 months now and have never seen PATS fail if cab temp is 85 degrees or higher
