I know this topic has been beat to death, but after searching the forum and google I haven't found out the answer to my particular problem. When I purchased my 2004 XLR it came with only one fob, the # 2. After around a month of searching I finally found a used one on ebay with the correct GM # 10337464 for 2004. Its also a #2, but from what I've read you can program multiple #2's or 1's. Today I tried the programing method to erase all earlier fobs and program the 2 that I have. I believe it was method # 3 that requires you to go through 3 ten minute cycles which clear all known remotes and then allow you to program the new ones in # 1 and # 2 positions. Once I was done cycling through and the message came up "ready to program fob 1" I inserted the new (used) fob into the fob compartment in the glove box. At this point nothing happened. The message stayed displayed and after 3 minutes turned off. I then realized that I missed a step and didn't have a fob in the glove box during the 3 ten minute cycles, so I tried it again and still no luck. Same thing happened. I've tried this entire process about 6 times using slightly different methods, including twice doing it exactly per the manual and I can't for the life of me get this new fob to work. I then read something interesting, and a bit unsettling in Chiltons manual, here it is:
"When a remote control door lock receiver (RCDLR) is replaced the original key fobs became obsolete, the key fobs can only be programmed to the original RCDLR. Key fobs and the RCDLR can only be transferred to another vehicle as a complete set. Additional new key fobs programmed to a RCDLR cannot be reprogrammed to another RCDLR or another vehicle."
So my understanding is that we cannot program used key fobs that have been programed to another vehicle... Can anyone confirm this, or is there another way to reprogram used remotes? I know I've read multiple posts on here and other forums with people that have purchased fobs over the last few years on ebay and such and were able to get them to work. They did not specify whether they were used, but I could only imagine they must have been, being new fobs are not available for 04. Has anyone successfully reprogramed a used remote, or am I the first to try this? Thank you for taking the time to respond!
One last thing to note, both batteries were replaced prior to programing.
