I have a 98 mustang with PATS II. I currently have three keys, one original Ford key, and two aftermarket keys from locksmiths. All of them have had a fair bit of abuse in the original Ford key doesn’t even have the loop to put on the key ring anymore. I bought three more original NOS Ford keys online and will have them cut in a locksmith this week. As of right now, there should only be four keys programmed to the car, the three in my possession and the one MIA original key that seems to be lost in the wind long before I bought the car. Assuming that no other keys have been programmed, I’ll have no issue programming these three new keys myself. However, if that’s not the case, I know that there is a max of eight keys allowed to be programmed. After I have reached eight, does it automatically start to erase the oldest keys in the system or will I have to pay a locksmith to reset the whole system? Thank you in advance.
