I have been having a problem with my garage door remote needing to be pressed four or five times before the door will open for a few days. I just replaced the battery a week or two ago and it was working great and the range was much improved. This is a Genie with Intellicode. The answers I find online are always replace the battery or reprogram the remote with the opener. The remote eventually works so it shouldn't need reprogramming.
Do the switches on the remotes wear out or anything like that? The remote and opened are about eleven years old.
