how to bypass the security

The resistor replicates the magnetically operated switch that senses the rotation of the key tumbler. The resistance range that was acceptable was something along the lines of 1k-13k ohms. I used the 2.2k because it was easily accessible here in town. When you do the relearn withe the new resistor in there, it will use the new resistance value from then on out.

Does the wattage of the resistor make a difference?

Thanks for your help,

Great, thanks for the quick reply! My new to me '99 K3500 wouldn't start, flashing Security light a last Monday. Had to wait til Saturday to dig into but when I checked it out it started up and has been fine since. I'd like to do the bypass so I don't have to worry about it happening again.

Thanks again,
Steve

If the battery dies, does the relearn have to be done again even tho the resistors is in place?
