😃 Tip 1) Does the car remote work?

Check to see if either the car remote or wall unit will activate the garage door opener first. As simple as it seems, in many cases that first panicked, “Oh my goodness it isn’t working!” is followed by the realization that the remote batteries are simply weak or dead. Incidentally, many remotes feature a blinking LED light that may actually flash to display a code which diagnoses operational problems. Consult your owner’s manual for more information.
