been working on a engine swap from a 1999 4.0 ranger into a 1999 ranger that had a 3.0 i have swaped so fare the whole trans due to the 3.0 trans not having a output speed sensor for the 4.0 harness have everything hooked up but pats disabled me with a b2139 code mismach error so i desided it could be the bcm or lock cyclinder and key so i swaped them from the donor and now i get a code b1601 incorrect key. any one else run into this ???? and if so whats a fix or is there a way to reprograme the key
