    I guys , so I'm hoping the knowledgeable 200sx owners can help.
    I've got a 200sx turbo S14 95 plate on a M.
    She's overdue an MOT (like 7-10yrs overdue) and it's time to bring her back to life.
    One problem....I've lost the keys and remote fobs.
    I've had a key cut so I can get in and crank the vehicle(chip not in the key it's in the fob)but immobiliser light is on.(passenger side of top dashboard)
    I've sourced a second hand keyfob exactly the same as the old one.( 2 round button black fob with Nissan wrote on it)
    Is there a way to programme the fob?
    Regards Ashley

    Immobiliser stuff needs NATS I think, not many people have that system.

    You'd best find those old keys.

    Aye, removing NATS is as simple as wiggling a single chip inside the ECU until it comes loose and it falls out - easy peasy - although not sure which chip lol

    Ok so I’m still struggling with the immobiliser system.
    Surely there’s someone somewhere that can programme the system?
    If I open Ecu ( surely can’t be that easy to remove a security feature) then I’ll still have no central locking etc.

    It is as far as I'm aware.

    And you will have central locking, just not remote central locking, so you'll have to put the key in the door.

    Horsham do this, they re program nats out of the ecu, if you remove the chip off the board by breaking it off, the em light will stay permenantly on apparently
