    Good day

    I wonder if anyone can help me?
    I am trying to make an auto immobilizer. I have a uhf key chain type
    transmitter and a matching receiver. My problem is the receiver
    doesn't give me a latch or constant switched +12v only a momentary
    +12v, I assume for a siren chirp. Can you provide me with a circuit to
    take the momentary +12v and use it to latch a relay with which I will
    immobilize the vehicle, until I re energize the receiver and then it
    will unlatch. I have tried using 2 x 12v relays but cant figure out
    how to wire them up to give me a latch.

    My e-mail address to reply to me at is:



    Thank you and regards.
