I've recently noticed that the ignition switch on my 2006 lx150 has gotten loose. When I put in the key and turn the ignition on, it will turn off if it gets wiggled. Twice tonight it turned off the engine while I was riding. It's also possible to wiggle it by hand when I first turn it on and the lights and ignition cut out. Is it a major PITA to repalce the switch? I'm assuming I can remove my cylinder and put it in the new switch. Where does the immobilizer live? Do i need to worry about it if I replace the switch?
