I live in a small community of 12 houses. Recently someone has purchased a new opener and it has the same code as our garage door opener. Like clock work our garage door opens between 4-6 in the morning just long enough to get a car out and then closes. We tried looking for the old school dial where you can change the code but to no avail. Can you please help. Thank-you, Phuong-Uyen Savage usavage2@yahoo.com
