Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of Thanks.

Here we have a key FOB for a 2007 Audi A4.

To change the battery, flip it over, and put the screwdriver between the key ring and this plate. Simply pop up. Take the battery out of the cover.

Replace the old battery with a new one. The battery stays in there all by itself. We just have to line up the tabs, and snap it back into place. Then check the operation of your key.

Thanks for tuning in. We hope this video helped you out. Next time you need parts for your car, please visit Also check out our other helpful how-to and diagnosis videos.
