    Nats not responding

    I ve done a search and found nothing to help me with my particular problem.
    All three fobs work, led's light up ect.but the car still does nt respond to any, not even the master.
    Yesterday it was working as normal even though it has done the above a few times before it wont work at all now.

    Sounds like a s14a to me as AFAIK S14's don't have master keys and the nats box is the important bit. IIRC the S14 one is as you say tho, its in the NATS book you get with the car

    According to the NATS II book, to resync the fob for the s14a
    you need to:

    1) Press the red and blue button of the keyfob together until the keyfob LED stops flashing.

    2) Release the buttons.

    3) The keyfob LED should stay ON.

    4) Press the red button for 1 second.

    The fob should work again

    I think if the batteries are okay and the re-sync of the keyfobs doesn't solve the problem then it is likely you have a fault with your NATS control unit. It sounds as though it's not picking up the signal from the fobs.

    Make sure the vehicle battery voltage is OK. Try connecting a battery charger to it, and then trying.
    Best of luck. Ian.

    I've done all of the above, and I've got one of the keyfobs to work. But the Master and the other one still don't work.

    Any ideas?

    You do realise that the master unit will only disarm the alarm or allow you to add another fob to the system? I.E. you should be able to unlock the car with the master fob, but not lock it again.

    this post should also help a lot of people who have purchased another new/used control box and need to know what to do for the initial setup

    I know this might seem comon sense but i kept tryin to do this in the house, reprogrammin the fob with the master but it would never work when i went to the car so last night i tried resetting the fob while in the car and it worked first time. do you actually have to be at the car to do this??? so in essence the fob is resettin the control unit in the car??

    Pete, you actually train the car to recognised the new fob. The master lets you put the car into the correct mode for this to happen (so in other words you need to be in range for it to work).

    Dazdavies, is your car a S14a or S14 (there are two types of alarm system, NATS I & II). I only know about the NATSII. If you don't have a master then you will need to get a new NATS control box and fobs.
