Another key fob question

[Jake D]

Sorry to post another key fob question, but after about an hour of searching through and reading, I still didnt see the problem I'm having.

Key worked fine about a year ago. It gradually started intermittently not working so I would have to manually open the doors. Since then, I replaced the battery. Didnt seem to make much/if any difference.

Now when I press the key, the red light doesnt flash rapidly like it used to, it flashes once every two seconds. Has this ever happened to anyone? Did I just happen to buy a weak battery that is almost dead already or is this some kind of other problem?

Thanks

Changed the battery again, and still have the same problem. after looking at the key closer, it looks like there is a decent amount of corrosion under the plastic battery holder. Not sure if unsoldering the battery holder, cleaning it and putting it back together would help/work, but ill probably give it a try since it looks like its worthless as of right now

Subscribing in case an answer develops. I learned something new reading this thread. I have one working and one non-working remote and I didn't realize they flashed differently. The working one flashes in a pattern really fast while the non-working remote blinks at a slow steady interval. Seems to be just like the OP.

I revived an old thread a few days ago where somebody said they had a method for reviving communication between the car and and a non-working remote but it didn't work for me or the others who replied.

I don't have any problem with my key fobs, but I have had my car for 4 years and I am sure the battery is geeting low.

Can I open up the fob and replace the battery (CR2032??) without losing any programming code and having to reprogram everything? Thanks.

I've replaced my battery, cr2032, without problem.
Dale K: seems your key fob has a couple of issues. If you can resolve the difference in flash frequency, you might want to try the fix I posted again. It did work for me, albeit some time ago. Both of my fobs flash normally.
