Thread: Key Fob Issues

For a little over a year now, my key fobs have been malfunctioning. I've changed batteries, rotated fobs, but still have the issue of my lock and unlock buttons not working. My alarm and trunk work just fine. My auto start button works, but you have to lock the doors, then press that button, so the function is useless at the moment. What am I doing wrong? Do I need a new fob? Does it need to be reprogrammed? I just got a new car battery this week, and thought that might help, but still same results :/

Thank you! I'll have to try that when I get home. I have no fear of opening it up. A cell phone case opener works well to get in the grove to pop it open.

You're going to tempt me to open up my fob after I've had a few drinks lol

My car unlocks now! still can't lock the door, which is what I need so I can auto start it. I'll have to work on my other fob when I get home. Maybe try and switch the buttons... Work in progress!

For the record, this totally fixed my issue! Yay! I initially cleaned the keyboard contacts with some rubbing alcohol last week, but when I reopened it, they looked cloudy, so I used a regular eraser to buff them up, and they're shiny now. Combined with the foil glued to the fob buttons = results! Thank you!!

What did you use for glue? Mine will work with foil for a few days, and then the foil (or the conductive paint) falls out of place.

I used elmers glue, but it didn't keep the foil on the buttons. I ended up going on ebay, and now I have a key fob of a cool color.

I got my ebay key fob in Jan, and it's still going strong. It's a bright blue, and looks awesome compared to the black one I had. It was easy to gut the OEM one, and transfer.

I've resoldered the battery tabs back into place a few times now and they usually hold for about a year. I try to be careful to not hold an iron on any longer than I need to as it may melt other parts of the fob. I honestly can believe I soldered something back in place and it works - thing looks fragile.

Anyone else done this?
