If you changed the batteries but your wireless garage keypad still will not work then I think I have a solution for you.  My friend had a wireless garage remote keypad that would not work and they thought it was just low batteries.  I put new AAA batteries in it but it still didn’t work.  Follow along to learn how to fix wireless garage keypad not working…

Step 3: Check the remote’s battery contacts for corrosion.

Look at the place where the ends of the battery come into contact with the remote and look for signs of corrosion.  In the picture below, the top right one still has dark corrosion on it but I had already started scraping off the lower right terminal:

The battery contacts should be shiny and silver but as you can see from this close-up, there is corrosion on there:

Step 4: Sand/scrape the corrosion off the battery contacts.

I used a utility knife to carefully scrape the corrosion off the contacts:

You also could use a piece of fine sandpaper (220 grit or higher).  When you are done the contacts should be shiny:

Step 5: Reinstall the batteries.

The polarity of the batteries is printed on the circuit board:

Step 6: Test the remote.

Before you put the cover back on go ahead and test the remote.  If you have an Overhead Door brand remote it will remember the code you have programmed into it.  Once I cleaned the contacts this remote worked the first time:

The remote works!!

Step 7: Reinstall the remote battery cover.

The Overhead Door remote that I was working on must be slid on from the very bottom.  I didn’t get a picture of it but here’s a diagram of how to do it:
