I am not sure now, but the transponder in the key looks like a small glass vial with piece of metal inside.
And there is no internal battery in ECU keeping the codes live. They are stored in ROM. But it is possible to lose the immobilizer/key connection, it happened to me last Christmas when the car was standing for 6 weeks and battery went flat. I had immobilizer error after and keys had to be re-coded to be recognized again.
But I donít think that it would be caused by removed battery, I had car with no battery for a year and it didnít happen, however low voltage of a connected dying battery made it loose immobilizer codes. So I think dead battery is worse that no battery at all.
