If you want to sell key fobs, there’s a market for both working and non-working units. Many online platforms and local businesses buy them for refurbishment, parts, or resale. To get the best price, clean your fob, check its compatibility, and provide accurate details when listing it. Some buyers offer instant quotes based on the fob’s model and condition. Shipping is usually simple, with some companies providing prepaid labels. Whether you’re an individual with spare fobs or a locksmith with excess inventory, selling them is an easy way to earn extra income.
