I'm about to replace my head unit and speakers in the car and that will require me to disconnect the 12v battery.

Am I going to have any issues with things not working or something needing reflashing when I connect the battery back again?

Also, same question with the key. One of my keys batteries is dead. Will it need to be reprogrammed once I replace the battery or am I good to go?

Thanks.

I’ve disconnected my battery and also changed my key battery and had no issues at all that’s why I answered no to your question….No secret

It's hard to convey humor across the Internet. I knew what you were saying. I was trying (unsuccessfully) to be funny.

I have a 2006 450 diesel, I'm in the USA, and my car had the digital readouts in MPH, after I replaced a bad battery, the computer switched back over to KM and I can't get the MPH back until I get the computer reprogrammed which I don't have anyone within 100 miles of me that can reprogram it. I have replaced the remote batteries without any issues.
