I moved into a new house and didn't have any issues with the garage door. About a week after I moved in, I bought a remote for the opener since the owner hadn't given me one. After programming the remote, we realized that my next door neighbor's remote worked my garage (but mine didn't work their's). I re-programmed my remote with a new frequency and fixed that issue, but now the garage opens on its own.
I've tried using the lock button on the wall but that doesn't help. The only thing that prevents it from opening is to unplug the opener entirely. I don't think it's an issue with the remote at this point because it opened while I was away from my house with the remote (luckily I made sure to lock the door from the garage to the house).
Is this likely an issue with the actual opener or the wiring? Is there anything I can do to check?

If it didn't open randomly before you changed the frequency (to avoid your neighbor) then you probably stumbled onto another frequency in use in your area, and that's why it continues to open unintentionally. You might want to record the frequency variations you have tried, then switch to another (most remotes support dozens of possible choices) until you find one that results in no unintended operation.
