Hello ... I have a new 2010 Edge Limited which was manufactured 6/10. I want to install a remote start system. Upon talking to a local installer, and after him seeing that I have "HA" stamped on my ignition key, he informed me that my vehicle has the new 80 bit encryption and none of the current PATS bypass boxes will work with 80 bit encryption. To verify what he was saying I called the vendor's help line for the product he carries, which is Code Alert by Audiovox, and the tech said that the installer was correct. The remote start could be installed and would work, but I would have to use the "key in a box" solution which means leaving a key hidden in the car. He also said that all remote start systems, including Ford branded systems, have the same problem. Any key with "SA" or "HA" indicates the vehicle is using the new 80 bit encryption. The absence of those stampings indicates the older 40 bit encryption which is not a problem. He says that until the makers of the bypass boxes overcome the new encryption problems the key hidden in the car is the only option. Anyone else run into this issue and is hiding a key in the car the only solution?
