6 Pcs Shopping Cart Key Shopping Cart Coin Keychain Holder Key Ring Silvery Mini Aluminum Alloy Key Ring Shopping Trolley Tokens Small Quarter Holder Keychain for Grocery Shopping Cart

I bought these to use at my local supermarket with the chain locked shopping cart so I didn’t have to search for a quarter. Very disappointed when they arrived smaller than a quarter and won’t unlock the chain. Returning.

ive tried this key at 2 different locations and they do not work nor fit properly
