If you only put the one key on it then demand a refund as the product (keyring) was not fit for purpose. Or ask for a replacement if you prefer.She still has the online store, I bought a couple of things from there a while back and they’re not the best quality, I got the Debbie tee which is almost completely see through and the Darlene keychain which has fallen apart. She does say on the site now not to put more than one key with the keychain but I only had my car key on there and it still fell apart. Disappointing but not surprising I guess
It is not being unreasonable to do so.
