I NEED A REPLACEMENT TRANSMITTER FOR THE LIFTMASTER GARAGE DOOR OPENER INSTALLED IN THE GARAGE OF OUR HOME HERE IN ST. GEORGE UTAH. ACCORING TO THE MANUAL THAT I FOUND ON TOP OF THE OPENER AFTER WE MOVED IN THE OPENER IS A MODEL 3265-267 1/2 HP WITH A PURPLE LEARN BUTTON. WILL YOUR MODEL C-SP-315_B TRNSMITTER WORK WITH THIS OPENER?
THANK YOU,
BRIAN GAARDER
