Trying to find a remote start that won't interfere with keypad on drivers door. With other cars I had remote start with if you used the factory remote it would set off alarm. Think of 200 series. I have a 09 lariat.

 

I have always used Viper aftermarket systems. No issues. And, yes I have keypads on my trucks,

They have quite a few choices. You'll have to do your research and find what you want the system to do/not do.
