02 Mazda B3000/Ford Ranger using Maxisys Elite. Trying to program new pats keys. I can access the PATS Functions screen through Service/Body/Security/Pats selections which brings me to Passive Anti-Theft System info screen. When I select OK button the next screen shows "Set the ignition switch to ON". When I hit the OK button it takes me to a screen that says "No Pats functions can be performed unless security access is granted" If I hit the OK button it returns me to the Security/Pats Functions screen.If I don't hit the OK button it never progresses further. I've tried waiting as much as a half hour doing it either way and it will never give Pats functions access. Am I missing a step or is there something else I should be looking for? I have made sure I have erased any fault codes (the only one remaining being P1000 and have also performed a KAM reset. Am using OS V03.50.00, Mazda V7.26 and Maxiflash-Pro FW 4.00 VCI SW version 5.16.00. Thanks in advance for any insight anyone can give.

  Hi and thanks for your reply witsend but I had already seen your post from previous search of my problem and had tried from both areas. I can access the PATS function menu from both areas and have tried both ways however once in it doesn't seem to progress any further indicating a bad tool  software parameter or link allowing for the functions or some other fault. I can see all data pids for the PATS system, it just seems Autel won't let me access to program them. After much more diagnosis on my own and research on these forums and the internet as a whole it seems this has been a very long and ongoing problem with the Autel software. Im almost positive at this point it is their software as it doesn't even have the requisite countdown timer for security access and they have the PATS functions in the body module folder which it is not in on this vehicle. Though I do like using the Autel line of equipment overall it begs me to question why I would be interested in buying their new dedicated tool for key programming when I can't trust the equipment I do have to do it when it says it's supposed to. If they can't get it right on previous tools they probably won't have it right on the new ones.
