Ford cab keyless remote entry....

Thanks all... my primary issue is that there is no remote keyless entry module in the unit. I thought about aftermarket, however, after a call to Ford Motorhome Support, I decided against it. They said that if the aftermarket part and/or installation caused a failure in any of the vehicle systems (like the ECB), it would void the warranty.

Lord knows, I don't want to mess with my warranty!
