I've got two keys for my 1990. One for the ignition (long key), one for the tank (short key). The seat lock mechanism is missing altogether, so I have a dangling wire there.

Which raises a couple of questions from me:

1) Are there supposed to be separate / different keys for the tank and ignition? It isn't just that they're cut differently and different lengths, the cross-section is even different so you can't interchange them.

2) Which one worked in the seat lock, and finally

3) If I buy a seat latch mechanism, will one of these keys work it or will I need a 3rd key? I don't know if this bit has tumblers or not.

This bike's a bit hapless; I don't know what the many PO's did to this thing.

on a bike 1 key should run everything.  someone has changed ignition or gas cap

what I did with my bike is have a spare key made, one side cut for ignition, other side for gas tank.  same key works both locks then.  you can remove the tumblers from the seat lock then either key would fit it.

I have one key that does it all.  Never knew there were more? lol

I have 1 key for all 3 locks, i think you will need to talk to a motorcycle shop to get a new set of tumblers for all 3 locks but i have never had to do that before so i am not 100% on that but one thing i do know is it will probably cost a few $$'s

good luck

mine had different seat, gas tank, and ignition keys

or just grab a seat lock with a third, different key?

Yup, one key should do all three locks!

Might cost a bit to change all of them out

OK, that's what I thought. I'll have to take a look at them and see what I can do.

Mine has differant ignition, gas, and i assume seat because i cant get it to budge with the gas key so i use the dangling wire like you.

It is not too difficult to take apart the gas cap and seat lock to rekey them to match the ignition. They all share the same tumble and both use less tumblers than the ignition.

my ignittion key doesnt even fit in my gas or seat lock though. its too wide and too tall.

Until reading this thread, I didn't know there are motorcycles requiring different keys for different locks on the same bike. Why would they ever do that?

They do not come from the factory that way. Parts have been changed.

Wear and funkyness can also affect things. I got new keys cut at the dealer since I had only one key and it was somewhat bent. The first one they made would not turn the ignition, but works the tank and seat OK. They were using a "by the numbers" cutter for the key, and guessed that the key might be worn, so they upped the numbers by one and got a key that works the ignition - but doesn't work the tank.

The original bent key works all three locks OK, but being bent, I worry about it snapping off and stranding me. I may take some time to fiddle with the new keys by comparing to the old key and see if I can make any improvement - but the shape certainly looks right - it just doesn't work right. For now, using two keys works better.

Wire wheel the edges of a new key to work better in a worn lock.  Good luck!

Yeah, I would need to post a pic of the keys so that you can see the differences. The keys are from completely different key blanks. So I can't just retumble the tank lock.

Looking at a cross-section: the ignition key a grooves on the sides, in addition to the offset. The tank key is simpler, and just has the offset. Both keys are cut on both sides, like every cycle key I've ever seen. I'm curious as to which is the original 1990 key. I assume the tank key's not.

I've no doubt that stuff's been changed on this bike; it's been resprayed and I really don't know the history on it. Runs well, though.
