Posting your garage door model would help, but there may be a button close to the LED on the garage door opener that you have to depress to allow the two to pair up. Assuming that this is the similiar to my garage door control mechanism, if you have the dip switches set correctly you need to depress the button mentioned above and then depress one of the buttons on the remote.
