5th gen nissan antitheft. it NOT an alarm at all. it will simply disable the fuel side of things via the computer.
if you swap the computer it's gone anyway.
as for the remotes - button cell is what I have seen in most of the ones I have worked on. the one I have here currently has a dead key. remote works but the transponder doesn't - result - car cranks but wont go.
jon,
he's asked me too. doesnt have the NATS codes though so he's out of luck. told him how to ATTEMPT to get them. if he's successful then the key should be able to be done locally.
if you get time I'll run a tool over yours to see if I can do it.
