I have a Viper remote start in my truck, it was installed over a year ago, and has worked great.

Today I go outside to move truck using key, truck doesn't crank or do anything, I push button for remote start and truck starts right up.

Any ideas what might be bad, ignition switch?? I tried both keys and same problem.

This is on my 99 Ranger

 

There is probably a conflict between the PATS bypass module and the standard pickup for your ignition keys.

Locate and disconnect the PATS bypass module and try the key(s) again.

I'll give it a try. But why would after it has ben woring for over a year would it cause a conflict now?

 

Because it may have broken.....
