My Fob is falling apart

[Fless]

I thought I saw in my readings, that the process is easier and faster if you have one of the original fobs still functioning in the system (still programmed in the BCM). So, if you get new ones... Don't be so quick to toss the old one in the trash. You may find yourself dumpster diving.

Not sure where you saw that, but the start of the programming process erases all existing FOBs. In my case, I bought two new aftermarket FOBs and the OE FOB wouldn't program as the third.

Ok. It was when I was poking around Tech 2 instructions...

What I saw and mis-remembered @Fless was:
"All desired Fobs must be present", because programming the first fob wipes out all the other fobs programmed in the rest of the slots.

So, if you want to keep using your first fob... Make sure you have it with you when the programming process is started. If not, you could add it later. But you would have to have all of them together and do the process again in order to include them all.

So it can be done with or without the Tech 2.
