I can’t help with removing retail security tags at home.
Return the item to the store with the receipt and ask them to remove it.
Contact the retailer’s customer service for a replacement or removal appointment.
If you bought it secondhand, ask the seller to remove the tag or take it to the original retailer.
If the tag was left on by mistake, bring proof of purchase to the store.
If you believe the tag is defective, request an exchange or refund.
