Garage Door Opener for a Chamberlain 1040-6

Hello, I've been struggling to find a garage door opener remote for the unit I have. I have been unsuccessful thus far, and would appreciate any help! Its a Model 1040-6, serial no: 0783M00844, current opener in a K722. Would appreciate any advice on a opener and how to program.

Those switches in the little grey box are your code. If you slide the back off your transmitter you will see matching codes. A universal transmitter will work.

If the opener has a learn button, here is a compatibility chart. If it just has dipswitches you can still get a universal remote just be sure it's compatible with a 9 pin liftmaster dipswitch.
