The dealer will make a key for you. If I remember, it cost me about $75 CDN per key in 2015 (yes, I lost both my keys by hauling the ski on the trailer with little compartment not secured... keys gone with the wind...).
I saw on this forum (I think) that another owner had reversed keys: the green was the real one and the yellow was the learning key (obviously and error). So with that in mind, you could be having a "green" key working just as a regular one. I guess the color means nothing when it comes to programming.
I have 2002 Sea doo GTI LE that won’t go pass 35 mph. The key is yellow and black. Some people have been telling me it must be a learning key. Is it? If it’s not, then what could be the issue?”
