I'm not sure this is where this goes or another forum would be more appropriate. We just ordered a new Ford Interceptor utility for a battalion chief rig. It was supposed to come with keyless entry, however, it came in incorrectly. Long story short the dealer stated they could send the whole car back and order a new one with keyless entry but it would take another 8-10 weeks for it to come in. They said it is not as simple as programming the new BCM for keyless, and the dealer does not want to put in aftermarket keyless because they say it will interfere with the BCM. I have installed tons of keyless entry and remote start systems over the years and never had an issue with it interfering with the BCM. We do not have time to wait another 8-10 weeks for another car so we have accepted this one. I guess the question is has anyone installed an aftermarket keyless system on a PIU? If you have what system did you use? Have you experienced any problems?
