5704 issues with remote start f350 diesel

Hey Kreg, One question for you. when I bought the truck. I received a key with an S on it which apparently is 40 bit key Before installing this new system,like I told you before I picked up a new key from Ford. the key had an SA on it which is apparently a 80 bit key. Now both keys work fine. Both start truck fine. Do you think that this could be an issue with the pkall programming? ThanksDenKat

Or if anyone has a sure answer please let me know ThanksDenKat

The "SA" is thought of as an "80" bit key and will work as an "80" bit key, however it can be programmed as a "40" bit key to an older "40" bit system and will work correctly ( downward compatible ).  Not sure how the PKALL will respond to this situation, never came across it before.  I believe it will respond and program normally because the PKALL is "watching" the RX & TX wires.  Too bad you're not closer.  I'd love to try an iDatalink module on your truck.Soldering is fun!

Once again thanks a lot man. It was fine... Here is a blog I found to test for 40 bit or 80 bit Understanding the Difference Between a Ford 80 Bit & a 40 Bit Ford introduced an 80-bit encryption in late 2009 and this caused a lot of confusion as to which models it was available on. The main question is which models use the 80 and which use the old 40 bit? Contrary to popular belief, the SA marking on the key does NOT indicate a vehicle uses 80-bit encryption. In reality, the SA marking indicates that the key is 80-bit compatible, but the vehicle itself could still be using 40-bit encryption. What does it mean? It means that Ford did in fact release SA keys equipped with an 80-bit transponder, but the reality is that the same transponder can also be used in 40-bit vehicle, making it backward compatible with older vehicles. Consequently, if you see an SA key it is important that you do not automatically assume it is an 80-bit type. It all depends on the vehicle, not the key. How do I Differentiate Between the 40 & 80 Bit? To determine which encryption type you are dealing with, you must test pin 1 at the 4-pin IMMO connector on the key barrel for the following conditions to determine if it is 40 or 80-bit type. An 80-bit vehicle should provide the following values: § NO key in barrel: 0v § Key in barrel with IGN OFF: (+) 12v § Key in barrel with IGN ON: (+) 12v An 40-bit vehicle should provide the following values: § NO key in barrel: 0v § Key in barrel with IGN OFF: 0v §Key in barrel with IGN ON: (+) 12vDenKat

Secondly. Everything is fine. After listening to you and many other installers around the world. I'm putting another alarm system in there mostly likely the Omega Excalibur. The service at DEI or Viper or whoever sucks. They charge way to much for what you get. Other companies are offering more. Even computstar which I didn't like to much is better in my opinion. This is my opinion to anyone installing alarms. Viper does suck. sorry. Most of the alarm ideas and all originate from Omega I just found out. I'll keep you guys posted on my new car alarm installDenKat
