Tesla Keyfob Fix
by brian @ 18:29:46 - [perma-link]

I went on a trip this weekend, and was minorly inconvenienced by my Tesla key fob not working. I changed the battery before I left because it wasn’t reliably unlocking the car. At the first charging stop, the key fob was no longer detected. I went the whole weekend having to use the phone app to unlock and enable remote start every time.

Today i checked the new battery, and it was dead. I also noticed some corrosion in the battery area. I took the keyfob apart and cleaned all of the pieces with vinegar and a toothbrush. All of the blue flaky corrosion is gone. After letting the parts dry for a while, I put it back together, and it is working great!
