So I recently had my engine lock up on me (2005 g35 coupe 6mt) i replaced it with a 2006 350z motor so once I finished the swap car only cranks no start I have a red security light on fans immediately kick on and I had no obd so l checked my fuses and relays everything looked good I then swapped in the old harness now I have obd connection I have two codes that won’t clear are u1000 and c1136 I tried programming a key using a scan tool but it won’t work not sure where to go from here
