B&D Auto-Lock

B&D Auto-Lock is a keyless, automatic locking bolt designed to add an extra layer of physical security to B&D sectional garage doors. It automatically locks your door every time you close it, so your door isn’t just shut — it’s locked shut.

What Auto-Lock does

• Locks shut automatically, every time you close your garage door using your normal remote operation.
• Uses a heavy-duty locking bolt that engages after the door closes.
• Is wireless (no additional wiring required) and designed to fit discreetly within the door system.
• Operates using your remote control, and can also be used with smartphone control (optional, when used with compatible smart control).

Why “shut” isn’t the same as “locked”

Many garage doors can be closed (“shut”) without being mechanically locked.

Auto-Lock adds a physical locking point. B&D explains that:

• A “shut” door typically requires around 30–50 kg of lifting force to open.
• With Auto-Lock engaged, the lifting force required can increase up to 450 kg at the lock point (based on a door using an engaged automatic opener).

This is the core security benefit: a locked door is significantly harder to force open than a shut door.

Compatibility and installation

Auto-Lock is intended for genuine B&D sectional garage doors and is installed by B&D Accredited dealers.

• Can be installed on a new garage door or an existing B&D sectional door.
• Works when paired with a compatible automatic opener, allowing it to lock and unlock as part of normal door operation.
• Auto-Lock may be included with some B&D configurations (availability can vary by product/package), so confirm inclusions with your dealer at time of purchase.

How Auto-Lock works

When closing

1. Close your garage door as normal using your remote.
2. Once the door is closed, Auto-Lock engages by sliding a locking bolt through the door’s rail/guide track.
3. The door is now locked shut.

When opening

1. Press the open button on your remote.
2. The bolt automatically slides out of the rail/guard track.
3. The door lifts as normal.

Lock status indicators (LEDs)

Auto-Lock includes red and green LED indicators to show lock status.

The status normally displays for 10 seconds after a lock movement or button press.

---

Manual lock operation (power outage or emergency)

Auto-Lock includes an emergency lock/unlock button on the front of the unit.

To disengage Auto-Lock in an emergency

1. Press the emergency lock/unlock button on the front of the Auto-Lock.
2. This disengages the locking bolt from the guide track.
3. You can then disengage the opener (use your opener’s standard manual release procedure) and open the door.

Important: The emergency lock/unlock button is intended only for power outage or emergency, and is not to be used as the primary means of locking the door under normal circumstances.

Caring for your Auto-Lock

Preventative servicing of your garage door, opener, and Auto-Lock is important.

• If Auto-Lock is in a very dirty/dusty environment, vacuum residue from the lock and bolt before continuing use.
• Do not use water, benzene, or alcohol when cleaning the product, as these fluids can cause malfunction.

Ongoing care helps the system function within factory specifications, reduces the risk of failure and repair costs over time, and helps you maintain warranty coverage.
