John Greenslade Posted February 13, 2003 Share Posted February 13, 2003 On all my new cars there is a FM (i believe) I believe signal that prevents the car being started without the key. Does anyone sell this aftermarket that could be installed on a 70 240 Z. Quote Link to comment Share on other sites More sharing options...
TomoHawk Posted May 8, 2003 Share Posted May 8, 2003 I bet Radio Shack has a thingamabob you could use, but the transmitter would be a bit bulky, like a pack of cigarettes. Otherwise, you might check your local rice store or security shop to see what they have that would fit on your keychain. Otherwise, I think they way it works is that there is a tiny transmitter/receiver in the steering column that sends out a signal that bounces off a small chip on the key that causes it to emit it's own signal (like a tuning fork?) if the computer accepts the received signal, it allows the engine to start.
