Where Boss remote instructions are kept now

The Door Hero is not connected with Boss. The steps here come from Boss's own coding sheets, and from Steel-Line sheets for openers that also carry the Boss name.

The Australian Business Register lists the ABN of Boss Garage Door Operators Australia Pty Limited as cancelled from 23 April 2018. The Boss sheets used on this page are hosted on Steel-Line Automation's website.

Each sheet is written for one opener, so read the model off your unit first. If yours is not named here, check the manual for your model. How remote coding works on any make is in how to program a garage door remote.

BOL4 opener

  1. Press RADIO SET for about 1 to 2 seconds

    The Boss sheet for the BOL4 says the light globe flashes twice.

  2. Hold the remote button for 1 to 2 seconds

    When the opener accepts the remote, the light globe flashes twice again.

BOL6 opener

  1. Press the yellow RADIO SET button once

    Hold it for about 1 to 2 seconds, until the opener beeps.

  2. Press the remote button

    Keep it down for about 1 to 2 seconds, until a second beep says the opener has it.

BRD9 roller door opener

Boss's BRD9 sheet uses beeps as the signal, much like the BOL6. Press RADIO SET once for about 1 to 2 seconds so the opener beeps, then hold the remote button for about 1 to 2 seconds until it beeps again.

Steel-Line's HT4/WB13 sheet describes a Boss RD9 roller door opener with a SET button and an OK LED. On that unit, a press and release of SET gives two flashes and a 30 second window, and the remote button then brings one flash and two beeps. Neither sheet says whether the RD9 and BRD9 are the same unit, so go by the buttons and lights in front of you.

BRD1A roller door opener

  1. Take off the black cover

    The Boss sheet for the BRD1A starts by removing the black cover of the control console.

  2. Hold the code button

    Keep holding until the red LED lights.

  3. Press the remote button for 2 seconds

    The LED goes off.

  4. Release it for 2 seconds

    Let the remote button go for 2 seconds. The sheet says coding is finished when the flashing LED stops.

The BHT4 hand transmitter

Boss's BHT4 instructions split by opener type. On a roller door operator, remove the face plate, then press and release the small learning button under the large aqua button so the yellow LED comes on. Press the handset button once: the green LED blinks twice if the code is accepted. A second press of the learning button turns the yellow LED off.

Overhead, panel lift and tilt operators work differently. Push their Radio Set button with a pointed object and the courtesy light comes on for 30 seconds; within that time, press the remote button until the light flashes twice. The sheet says these operators hold up to 20 transmitters, wireless keypads included.

Clearing every remote from a Boss opener

The BHT4 sheet is the Boss document here that says how to wipe the memory. For a roller door operator, turn the power off, then hold the learning button while you turn it back on; all 3 LEDs flash twice. On an overhead operator, a 5 second hold of Radio Set clears every remote and the courtesy light gives 7 flashes.

For the BOL4, BOL6, BRD9 and BRD1A, check the manual for your model. After any clear, code back each remote and keypad you still use.

OL4 and OL6 openers with the Boss name

Steel-Line's HT3 coding sheet says its OL4 and OL6 openers may also be branded Boss, and its HT4 product page says the same of a two button keyring remote for those openers. The coding and clearing steps for them are in the Steel-Line remote guide, along with the RD9.

Boss remote batteries

The Boss handset battery sheet shows an A23 12V alkaline battery. Check that the one in your remote matches before buying a spare, and keep spares where children can't reach them.

If a remote with a fresh battery still does nothing, code it again with the steps for your opener.

Covers, power and a door in view

Two Boss sheets ask you to take a cover or face plate off the opener, and one has you switch the power off and on. Do only what the sheet for your model shows. If a cover won't come away easily, or getting at a button would mean touching wiring, stop there: wiring belongs to a licensed electrician and the opener to a door specialist. Test every remote with the doorway clear and the whole door in sight.

What to tell the door specialist

  • That the opener is a Boss, and the model on the unit (BOL4, BRD1A and so on)
  • Whether it drives a roller door or a panel lift, tilt or other overhead door
  • What the LEDs, light globe or beeps did when you tried
  • How many remotes and keypads you want working
  • Which battery the remote takes

What you can do, and what to leave

You can

  • Code a remote with the sheet for your opener
  • Clear the memory where a Boss sheet shows how
  • Fit a new battery before deciding a remote has failed

Leave to a door specialist

  • A cover that won't come off without force
  • A remote the opener keeps refusing, even with its own sheet followed
  • Any fault in the door itself, from springs to cables

What we would do

Photograph the opener's model label, and the buttons under its cover, the day a remote is working again. With the Boss sheets kept on another company's website, a clear picture is the quickest way for you, or a door specialist, to match the right steps next time.

Questions people ask

How do I program a Boss garage door remote?

Start with the model on the opener. On a BOL4 or BOL6 you press RADIO SET for 1 to 2 seconds, then the remote button for about as long, and a flash or a beep confirms it. Roller door openers such as the BRD1A use other buttons, so follow the section for your model.

Where can I find a Boss opener manual?

The Boss coding sheets used here are hosted on Steel-Line Automation's website. Steel-Line's own HT3 and HT4 sheets cover the OL4, OL6 and RD9.

How many remotes can a Boss opener hold?

The BHT4 instructions give up to 20 transmitters, keypads included, on overhead operators. The other Boss sheets used here give no figure, so check the manual for your model.
