Gas cap removal without key

[1983lux]

Hey all,

I recently got an old GS1000E that had been sitting, but it only came with a key in the ignition. Seems like the fuel cap took a different key (like it does on my Tempter). Any tips on getting the old fuel cap off with no key? Seems like aftermarket caps are available as long as I can get this one off without damaging the tank.

Thanks for any help!

I have taken a few caps off that were locked and I did not have the key, When I do it, I always destroy the lock, but the tank does not get damaged. First I find a craftsman flat head screw driver that will get into the key slot fairly well, then I put a wrench on the handle and give it a hard twist. Basically, I just end up breaking the tumbler of the lock and unlocking the cap. Not elegant, but fast and effective.
And most of the Japanese motorcycles I have owned have used the same key for the cap as the ignition, but when previous owners change parts, this can easily change. I have had second hand bikes that have had a separate key for the ignition, gas cap, helmet lock and seat lock, but originally it should have been one key.

Is there a 3 digit code on the gas cap lock?

Yep, there should be a three digit code on the gas cap, ignition and seat lock.
In my case the ignition was replaced and has a different key.

It's a very simple wafer lock, so poke around Youtube for videos of picking, raking, or using "jigglers" to open wafer locks.

I'd say it's well worth trying to get it open without destroying the core. Once you get it open and take the core out, you can very likely get it to function with the key you have by rearranging, removing, or filing the wafers. You'll lose a little security, but it wasn't a very secure lock in the first place.

Or, just twist it open with a screwdriver if you're in a hurry and don't mind replacing it. It's not all that strong.

Turns out the ignition key for the gas cap, it was just rusty and sticky. A bit of cleaning and lube and it’s good to go.

Wow, and it only took two years.

You can also make a L shaped pick and just slide the lock tab at the bottom of the cylinder and remove the complete cylinder. Then use a scewdriver to turn the locks. I wrote about this many years ago. The tab usually slides towards the front of the bike. Its not [erfectly flat to the bottom of the bore so some giddling will take place. But once you have the retainer slid over a little upward pressure will slide it out
