If it was like $5 I may have bought it for you. Sorry!

I guess it could be welded back

Obtain:

• A micro drill bit. Cheap off AliExpress. A bit more elsewhere.
• A trip to ACE hardware (or hobby craft shop). Get:
  • A thin metal dowel, as thick as the medium thick micro-drill bit. You don't need more than 1-2". Or you can get a couple of thin, stainless steel nails and hack off the ends to size. For this, you'll need good shears or a little saw. Extra credit for using a Dremel.
  • A good, metal-friendly glue or a dual-mix epoxy. I'd ask for advice.

Setup:

• Drill a tiny hole at the center of each side of the loop. Maybe 1/8" or 2-3mm. Standard drill. Protip: the micro-drill bits also fit a Dremel.
• Drill a slightly deeper hole on the body side (assuming it's solid).
• Dry run: test cut a length of metal dowel, enough to join loop and body. Cut to length until both loop and body meet and are flush. The hole shouldn't be too tight. Enough space for glue that comes later.
• The dowel adds structure and distributes stress pressure. Reason they use rebars in cement structures.

Assembly:

• Drizzle a drop of glue into each hole and a little on the dowel. A little more onto surfaces where the broken parts connect.
• Assemble body, dowels stuck into drilled holes on both sides, and loop.
• Wipe excess glue.
• Wrap some tape vertically to hold it tight. Doesn't matter what kind. It's just there to hold things into place.
• Leave overnight to set.
• Grab a beverage and stress-scream into a couch cushion. You are master of the physical universe.

Post-coitus:

• Unwrap tape, admire handiwork, then put back on keychain.
• Tell EVERYONE.
• Post back here with pictures. You've earned it.

Since this is on a keychain, it will be constantly getting pulled. Just gluing it in, or even welding may apply sudden strains and have it snap off at the compromised joints.

This way, it will outlive you and your grandchildren.

Hey looks like it is copper substrate, it could be soldered together!

A clamp and some E600 epoxy will make that good as new. Don't give up hope yet, OP.

I totally get it.

I would find a jeweler or metal worker and get it fixed. It might be expensive but apparently it would be worth it to you.

Edit:

Story time- I had a multitool my dad purchased for me before he died. I lost it one day and I was totally bummed. I mean I cried for like a whole day. Over a tool. Anyway I saw one on eBay once by random chance and bought it. When it arrived, it felt like the old one and I realized the object itself wasn’t special, it was what I memories and feelings it reminded me of when I held it. The new one did the same thing, at least close enough. So if repairing is not an option, replacing it might fill the hole.

I found one for you.

Drill, tap, machine screws with loc-tite?

Act like a proper car guy and slap some JB Weld on the bastard

Bummer, perhaps it can be repaired? By the way, be very careful about sharing photos of keys, it is often quite easy to produce a duplicate key from a photo.

I'd braze it but I'm a fucking barbarian.

I totally get it. If I like something and use it or have it around a long time I bond with it. Does not matter if it was expensive or cheap but if it was cheap/free I tend to love it more however if it was expensive I tend to be madder at the loss.

epoxy time!

You can reattach that with resin. It looks like thats what its made out of and its coated in somethibg metallic.

Absolutely don't just expoxy it, follow fubarx's tutorial below. Expoxy won't bind sheared metal to metal strong enough to stand up to pocket/keychain abuse. You don't have to go as fancy, but you need non brittle metal to re-connect those shear lines or it'll fall apart the first time you look at it funny.

That's a long time to own a thing. A lot of love goes into it.

Almost twenty years ago, I bought a wallet designed to look like an NES controller. I bought it for $15 from GameStop. Astoundingly, it lasted ... I think seventeen years. It was still usable but disintegrating pretty fast.

I had that wallet approximately half my life and got lots and lots of compliments on it. It was sentimental. I was sad to see it go - so much so that when I replaced it I bought a wallet display (something I didn't know existed before) and have it on my mantle to this day.

I think this is the most feels I've seen in this club.

I mean...can you kintsugi it?

Forza Motorsport 3 specifically hits a sweet spot for me so I totally feel your pain.

I still have the lock box they included in the collector ‘s edition of GTA 4, they don’t make promo swag like they used to.

New Achievement: Unlocked!

clearly a bad omen for Xbox :)

Think of it this way: if you put some effort into repairing it, it will have even more personal meaning than it did before.

The simplest thing you could do is just drill a hole on one end to pass a keyring through. That metal looks soft enough that any basic drill bit rated for mild steel should be able to punch through it in about a minute. File off the rough bits where the tab broke off, now it's custom.

Objects don't carry their own meaning. They have meaning because we give it to them.

I would just be so glad I noticed it happen and it didn’t randomly fall off when I didn’t notice and might be lost

If the epoxy method doesn't work out, perhaps try turning this event into an activity.

Learn some basic CAD, redesign the swag, but this time with something not Forza, but related to who you are now, and have it machined at PCBWay or similar.

At least you didn't actually lose that other piece

It’s understandable. I got a small plain desk lamp for free several years ago. Cracked the base two years ago and duct taped it as one does. A couple of days ago the light started cutting off and I thought I was going to have to replace it, but it turns out the LED lightbulb was the problem. I was mildly relieved I wasn’t going to get a new lamp.

This is from the Limited Collector's Edition of Forza 3, right?
I actually have this one, unused, lying around somewhere in the box at my parents home.

If you are not too far, I could probably ask them to mail it to you.

If it's that sentimental, put it in a frame, not back with your keys, otherwise it'll eventually break again.

Ive still got the book from Collector Edition that keyring came from! It's awesome.

I feel your pain. I've had some skate shoe keychains on my keys for 22+ years now. My keys just wouldn't feel the same without my DVS nylon straps attached.

Do what the other guy said using the micro drill bit, but use a segment of high gauge wire instead of the dowel. Also, solder it, don't glue it. Bore a little extra space for the solder.
