trying to get replacement USB transceiver for my wireless keyboard

Actually, quality businesses that make duplicates of the same sets do allow you to purchase a single duplicate lost earring.  James Avery is one such business. I do think that an expensive ($129 full retail) wireless keyboard with a rather long USB transceiver should have a replacement option.  Mine is "lost," the main reason being that I haul my laptop from college to XC meets to choral society to library to home, and I would disconnect that USB as it stuck out so much that I was afraid that my USB port would get bent from the joggles while in a laptop bag.  From above replies, that is exactly what happened to some. So the design flaws are 1)the thing is so long that reasonable people remove it to protect the "more expensive" laptops when in transit and 2) having designed it to be so long, no easy replacement process was designed for inevitable losses.  Seriously? Microsoft- either make the USB tranceivers small enough that people feel ok leaving it permanently attached to their laptops OR devise a replacement option.

I feel better after reading your posting. Our receiver also failed within 4 moths.  We got our MS combo around last Black Friday and it stopped working on March 8 this year. I actually like the combo and the keyboard and mouse are still in great condition.  However, after learning all the facts, I can only stare at them and wonder why I can't just get the receiver replaced so I can continue to be a MS fan.  MS should really put a warning sign on the box to alert consumers that the receiver is not replaceable so we can make informed decisions. 

I bought the Logitech version of the wireless desktop and it has worked flawlessly for well over a year. Plus, you CAN get a replacement "unifying" receiver and it will pair with up to 6 wireless devices. A better choice if you need to purchase again anyway.

i have a 2000 series keyboard and mouse, i tried calling, i wouldn't mind buying a usb transceiver, but they said that they can not help me, because i do not have a receipt (very hard to keep paper work for three years), so the warranty that we are sold , and us not needing to register the product, is a little false sense of security,  they said they are sorry, but i would have to buy a whole new set(keyboard and mouse), so there is no use of having serial numbers if they cant track the product with that(as other products can without paperwork for even small products like flash drives), this is very disappointing as i assumed that Microsoft would offer better service than the other cheaper brands on the market, but they offer no replacement parts, so they are the same as buying a cheap product and just dispose of after a year or two, so much for there three year warranty.

You are absolutely right, I can recall there was time I tried to search some of the MS products, I can’t able to find it since it required a serial number of the unit that I’m looking for. But in your case they didn’t consider the serial number instead  they’re more particular of having a receipt of purchase. It’s kinda frustrating transaction.

I believed Microsoft Company really trying to do some strategic way of developing their software and hardware environment.  In parallel to that they should have improve the customer service “after-sales service”, like provide a tracking system for the sold-out product from small item to big item. Somehow it gives to customer satisfaction and adhere customer to repeat purchase their cheaper products in future.
