I need program a new code contro JR 323 - Jensen JER-422 Universal Remote Control

You need the sheet that came with the remote. If the manufacturer's codes do not work with your ??, then you need a more modern remote. The codes must ALREADY be in the remote to be used. The code is part of the REMOTE.
http://www.tvcodes.com/ may have the code for you.

I have a Jensen Universal Jer 323 remote. My TV brand is Sharp how do i program it and what code number do i use and also instruction for it.

In the JR-300 manual, only code listed for Sony TV is 0000.

Here's the link to the codes:

I'm not sure if your remote will operate the vizio TV. You can try a code search and see if that works because the vizio TV is not listed.
Here is the user's manual.

try this:

1. Press the device button, ex. TV and the power button for 3 seconds until the on/off button stays lit.

2. Once the on/off button is lit, press the on/off button until the unit turns off.

3. When the code is located, press the stop button at the bottom to save the code.

Thanks for the code to set the code you must hold down the tv button while pressing the code and the power button should light up after dailing the 4 digit code

You actually do not require the number to program this remote. If you hold down the component you are wanting to link it to eg. TV and press the power button for 3 seconds the on/off button will stay lit. Once the on/off button is lit, you then just press the on/off button until the unit turns off. You then press the stop button at the bottom. You should be able to turn your TV on now!
