Keyfob amnesia
First I'm sorry if this is a dupe , but I searched and couldn't find answer . I replaced the battery in my keyfob , relearned the fob , and it keeps losing the memory after less than an hour . Any help would be appreciated and as always thanks in advance .

My fiance's 99 has the same problem.....I am looking at just buying a new fob, I think this is probably the problem......but I am anxious to hear from anybody else that may have/had this problem and what their solution was....

First thing to do is see if you have any DTC codes in the DIC. Here is the procedure.
This is the absolute best C5 Code web site!!!

Once you write all of the codes down, clear them and when the FOB fails again, check the codes again. Post those codes.
A battery low on charge or one that is going bad can cause the BCM to loose the FOB sequence code and it will stop working until you re-sync. Can you do the RE SYNC procedure and get it to work for a chort period of time??

The second is, someone posted on repairing the fob, so i went back and was able to repair my old one. There is a rectangular component at the top of the PC board that had popped loose from the solder connection. After touching it up, it worked fine again.
