Key with a magnetic imaging process involves "Ferrous metal" which would be mobilized in presence of impulses. Chances are that your metal is non-ferrous, and conceivably titanium. But, cannot be absolutely certain as 20 yrs. Discuss with several radiologists and get your physician involved. A CAT scan could be used if this cannot be resolved.
