Key Fob
I recently had to replaced FOB #1. Now the memory system seems to have gone nuts. The FOB was setup according to the owners manual, FOB 2 is still recognized yet nothing works as before no matter how I set things up. Any ideas?

If you didn't reprogram #2 when you programmed the new #1, then you didn't do the program procedure correctly.
First, you are aware there is a "short" programming procedure to add another FOB, which in most cases would be #3, which means the new one won't work with the driver memory settings. Only #1 and #2 can work the memory settings.
So, if you just want to "add" FOB #3 (or #4, the max is 4) then you use the short procedure.
To make a new #1 (or #2) FOB, with access to the memory settings, then you have to use the "long" programming procedure, which is lengthy. Doing the "long" procedure means you erase all existing FOB's from memory and start over. The first FOB you program will be #1, the second will be #2 for memory settings purposes.
The procedures in the manual seem to work only sometimes. Here is a verified and tested procedure, long and short, that will work if you follow exactly.

OR you could go to the dealer and have them do it, probably for a fee. Good luck.

With all due respect, I've never heard of this. Perhaps you can correct me, but you have to have a #1 in order to be able to use a #2. In other words, you can't use a #1 for #1 and then use another #1 for #2. It has go to #1 and then program #2. For #3 you use another #1 and for #4 you use another #2.

With C5 and C6 the fob number is determined by the order in which it is programmed, not the fob number. You can program two 1's as 1 and 2, etc. That's why you have to follow the procedure exactly if you want the proper memory reactions.

The number stamped on the FOB case has no meaning other than something to look at to determine which one you have, to know which memory settings it will utilize.Disclaimer: That's been my understanding all these C6 years. I'm sure Talon90 or someone else more knowledgeable than me, would have corrected me by now if I was wrong. :o

However, if he used the short instructions that just add a fob, the car would have programmed the new fob as #3, regardless of the number engraved on the back of the fob. That fob would have no memory capability at all.
Bottom line: if a new fob is programmed with either set of instructions in the owner's manual, the number engraved on the back of the fob means nothing. Any new fob # can be programmed as any fob # if the right procedure is used.
We really need to know how the new fob was programmed.
If the dealer or someone else programmed the fob with the electronic device used to program fobs, then that's a different story.

All fobs are electrically the same. The number stamped on the outside is only so you know which is which. The number corresponds to the order that the fobs were programmed at the factory. By using the long procedure, the fobs can be programmed in any order...in other words you could take four #1 fobs and make them 1,2,3 and 4. Or you could take a number 2 fob and make it number one, etc.etc. The fob can be marked with a marker or label so they can be distinguished from eachother. The fob that is put in the glovebox slot FIRST, will become the #1 fob....no matter what is stamped on it...the second one in the slot will become #2...etc (using the long procedure)
