I posted the wrong model number. Under the front light cover, the Model is 13561.

I've folded the antenna wire in half but the garage opener still operates when the remote control is more than 200 feet away.

I then coiled the antenna wire but the opener still operates when the remote control is more than 200 feet away.

What do I need to do so the opener operates only when the remote is within 100 feet?

Can you remove the antenna wire from the opener, if so, will the
remote open the door inside 100 feet?
