I regularly google for self-help youtube videos. I just watched video #1 and it is the best instructional video that I have ever seen. I has everything you need to know and nothing extra. Granted, it's a pretty simple task, but the video made it so easy to follow along. I wish all videos were like this. Thanks.

You don't need to use a screw driver with this type of fob as the end of the metal key has a flat edge which is ideal for popping off the cover!

Will the key need to be programmed again for the car?

It should work without having to do anything special (other than replace the battery).

I don't think that the key fob has altered the horn setting, in my over 40 years in the car trade this is enabled and disabled through your car menu settings this should be fully explained in your vehicle handbook.

I've seen 2 diff. Y'Tubes on this. One shows the battery writing faces AWAY from you as you work inside the fob, and makes a point of doing that. This one shows the writing FACING you as you replace it. Written texts say to put the writing "facing up"... hmmm, is up the face of the fob when you are using it pressing the buttons? Facing up at you as you look at the insides? I know I'm splitting hairs, but I wonder if it makes a difference at all? I have a 2016 Kia Sportage, and when I opened the fob, I was seeing the BACK of the battery, the non-written side. The first Y"Tube I watched said this was correct, seeing the back of the battery, writing no longer visible once I put it in. In both cases, I was surprised because manufacturers like their name to be visible. I use that smooth surface to write on it the date of install with a sharpie, as I do with all of my batteries. But I am damned curious, 2 Y'Tubes, 2 different placements. My fob works now just fine, BTW.
