                         Keys and I are not friends. 
For my 2004 Jazz I've put my spare key in a weather proof pouch that has a metal backing and located the pouch to the body of the Jazz by means of strong magnet (sourced from a broken microwave oven). 
The CR-Vs key is somewhat more sophisticated. 
The question is: Could the key's operations in any way be corrupted by magnetic fields?
