Is there a trick to open a GL500 or 650 fuel cap without the key, like there is on a CX500 Deluxe?
I just picked up a parts bike with a decent looking tank, but no key. I suppose I could have a key made from the code on the luggage rail and hope they're the same.

Look at some youtube clips on picking locks. It's not difficult with the simple ones.

Use your right angle pick to rotate the slot while you manipulate the 4{?} pins.

I've even seen pin rattlers made from electric toothbrushes.

A key that fits in the lock can sometimes do the job if you slide the key in and out rapidly while attempting to rotate the lock. Generally you want a key with a large 'tooth' on the end.

R locksmith like Kat Key in St Paul could pick & make key or give us the lock code you find or I can bring over my loose collection to try..

I also pick a couple locks myself after watching a locksmith do it in 2 minutes and then watching a YoutTube video.

GL650. Just an engine, fuel tank, and half a bent rolling chassis. I'll strip it for spares and scrap the frame. In my mind, that's not another bike.

I found another key yesterday. It's a duplicate, so no code. Just realized I can check the 500C tank it's sitting in.
I should probably try my collection of Honda keys in this GL tank and hope for the long shot.

I did some YouTube research last night and found some stock to make tools. (I knew I was saving those wiper blade stiffeners for something.)

I'd like to reuse the cap. That calls for finesse.

Thanks for the advice, guys. I was able to pick the lock after making the appropriate tools.
Paul, do you still have panniers you're trying to get open. I could make an attempt to pick those.
Now, does anyone know how to extract the cylinder from the fuel cap? I found wafers on eBay that might match what Honda used, so I might be able to rekey it.

IIRC there was a post within the last couple of weeks where the poster opened the cap by grinding off the edge of the chrome cover so that it could be removed to access the inner workings including the cylinder.

All this talk bout lockpicking and those youtubes on shimming padlocks just reminds of the old saying....."locks are to keep honest people out........" The cap lock would be pretty easy to do...you could even use a silca blank and make a "skeleton key" for less than $2...
Just noticed its already done.....👍

I saw that thread, but I'm hoping for a less destructive approach.
I managed to get a helmet lock off, so I have a code: 216 (or maybe 218. I'll need to take a closer look.)
Anyone local have key #216?

That's on my way to work. I might stop in there this week.
I already got the cap off, so no boom!
The tank is very rusty inside. But I don't see any blistering near the seams, so it might clean up OK.
