I inherited a 2002 Tracker Pro Team 165 with a Mercury 25hp. My deceased uncle had misplaced the key(s) several years ago. The ignition has a code of 241 on it. My local locksmith said that code was associated with approx 80 different keys and said I should just install a new ignition / key to resolve the issue. I have two questions: is there anywhere I can get just a replacement key? If I replace the ignition switch, how do I know which one to purchase ?(tons of them on Amazon and eBay) Thanks in advance for any help.
