Returns for Repair or Replacement
TheKeyKey.com provides a 30-day repair or replacement warranty. Please obtain an RMA number and follow the return instructions included with your number.
All defective, dead on arrival (DOA) items will be inspected and tested by our RMA department. If the item is tested to be in working condition, the RMA will be rejected and the item will be returned to you.
Some items are non-refundable and can only be exchanged for the exact same item. These items are described as "not refundable" on the product detail page.
Defective parts returned for replacement by TheKeyKey must be received within 30 days of the original invoice date. Items received by TheKeyKey after the initial 30-day period are no longer eligible for refund and will be forwarded to the original manufacturer for repair or replacement only, the choice of which will be at the discretion of the manufacturer. For repair or replacement inquiries after 30 days, please contact the manufacturer directly.
For product replacement or refund requests, please return the entire item package including all accessories. Package contents will be verified for completeness before a replacement / refund is issued.
Note that any physical damage will automatically void the product warranty and we will return any products that exhibit physical damage back to you. For example, we cannot accept CPU returns if the item is cracked, chipped, burnt, has bent pins or if the item has sustained any other type of physical damage. We highly recommend carefully reading the manufacturer's instructions before installing your product.
Please make sure that your item is actually defective and that you have ruled out other incompatibility possibilities before returning the product. When we receive the returned item, we must test it thoroughly to verify that it is actually defective because our suppliers (usually the manufacturer) will not accept returns or exchanges for working items. If we determine that the returned item is in working condition, we will ship it back to you.
