When I bought my 05 zenith a few months before Xmas it came with 2 keys, one that worked but was worn and one that was in bits in an envelope. I've replaced and re-cut the one that was worn and that is now in a new case but I don't like having just one key for a car that locks itself. I've ordered a new case for the broken keyfob and know a guy that will cut it for me but I would like to know how I can program it to the car. Currently it says "ignition error" because I've tried this circuit board in the new key and so I know it doesn't work. Any help would be much appreciated. The reason being is my wife is scared to drive the 407 because she thinks it's too long and I'd like to give her her own key to try and inspire confidence as she is disabled.
