Product Description
This looks like my keypad, but how do I know if it's the right one?
1. Frequency: Check the back of your remote or keypad to make sure the frequency is 390mhz (megahertz).
2. Dip Switches: Open the battery compartment on your old garage door remote or keypad and look to see how many dip switches (tiny switches in a row) it has. If your old remote has 9 or 12 dip switches, then it's a match for this keypad. If you don't have your old garage door remote, you can also look to see how many dip switches are on the back of your garage door opener (the overhead unit in your garage). The number of dip switches on the back of the opener is the same as on the remote or keypad.
