09 civic and 05 mazda 3 no start w/key

Boy, now that you mention that I doubled checked the wiring diagram for the civic. The first one said keysense n/a but the other said there is one. I'll try that. Same for the mazda. The group consensus is that the pink from the bypass should not be needed though?

Yes.

Agreed. Very few vehicles actually require the pink wire connected. I would guess that it either wasn't sensing the tach or that the ring may not be positioned quite right around the cylinder. Disconnect the pink, check your tach programming and bypass ring around the ignition. If I remember correctly, the Honda's can be picky about the ring positioning and it must be tight (use a small zip tie to tighten the loop around the cylinder). Or possibly look into a data type bypass. They can be more reliable.Kenny

save yourself the hassle and purchase a idatalink ads-al-ca or dortin honda sl3, key override all, evo can or evo all. you will have reliable bypass solutions and never have to worry about the immobilizer. data bypasses are more reliable than key in a box.Ted
