I have a XL750 as well and tried to reset the code by unplugging the blue wire in front, holding down the code button for 3 sec.....then when i input the 4 diget new code (A, B, C...etc) i get a "error" message. I plug the blue wire back up and input the new code and it doesnt work. I still get an error mssg. What can i do?
