Replacing Fuel Gas Cap and Ignition Switch

[Robin600]

Hello, I have a FZS600 Fazer Foxeye from 2002 (5RT1), but the ignition switch needs to be replaced because its worn and the key struggles to turn.
I want to be replace it as a set to be able to use the same key for both the gas cap as the ignition switch once replaced.

However here in the Netherlands I can't find any ignition switch + gas cap set for the 2002 model, but there is one available for the 2001 model.
Is there any difference in these two parts? The part# are different for both models, but they look very similar if not the same if you ask me.

Part# for FZS600 2001:
Ignition Switch: 4NA825010200
Fuel Gas Cap: 4HM246020100

Part# for FZS600 2002:
Ignition Switch: 5LV825011000
Fuel Gas Cap: 39P246020000

Thanks for any help

Both these locks and the problem with them being difficult to turn is a well known old issue.  What often works is a good clean out with something like WD40, flood them, then dry them out with brake cleaner, finally a good dose of dry grafite.  When you use each the trick is don't push too hard and turn slowly with a slight up and down motion to get a better feel.

Give that a try first, before you go the replacement route as that can be very costly and difficult, many pattern replacements either don't work, cause ignition faults or just fail in very short order.

Is it struggling to turn after the steering has been locked?
That issue has been on here before, and even my bike does it, but the very simple fix if that is the issue is to pull the handlebar to the left before turning the key, then it becomes very easy to turn. It's a very minimal turn with whatever is left, but it does free up the key against any resistance.
Works the same when putting the steering lock on too, just hold the handlebar as much as it will turn to the left before using the key to lock it.

Hi, thanks for the responses.

No, the ignition always struggles to turn, now even worse than before, before I needed to push it towards tank and with a some fiddling it would turn, now it just seems as if its a wrong key! It basically rarely works but only with a LOT of struggle and force, I've dosed it in with multi-spray but it didn't effect it, I've just tried graphite (from a pencil) and it doesn't seem to do much either, I haven't given brake cleaner a try yet, will do that and will also try with some graphite powder from the hardware store tomorrow.

This is a issue on the fuel tank cap too, not just the ignition barrel, it also works fine going from "ON" to "OFF", no issues there.

It's very possible you've left it too late or if the bike is new to you previous owners did nothing to correct the problem and the lock segments are worn beyond help. It is possible to rebuild the lock but it's not easy.
