After a power failure my nexus 8 alarm remote pads would not reset basicaly my code would not work , got the maual and tried the factory code to reset 1234 still would not reset , finally as per manual removed connections from battery inside box and aux fuse , refitted and went through engineers prog 7890 , all okay. Codes on remote pads come up rr t5/t6/t7/t8 but still can't reset , any body out their got any hints

I just disconnected the main power and battery cables going to the Nexus box. I don't use the alarm anyways.

I know this is a bit late from when yours went off but I had the same problem last night, how did you resolve this problem?
