How To Unlock a ViewSonic Projector Using Remote or Control Panel?


Nobody wants to accidentally change their projector settings while watching their favorite movie at home. Even more so when they’re leading a presentation at work or school. Locking the Viewsonic projector can prevent you (and other external influences) from unconsciously altering your settings. 

This article will go through each step of locking and unlocking the Viewsonic projector using the remote or control panel.

How to Lock Viewsonic Projector

Locking the Viewsonic projector is a pretty straightforward process. Yet, we’ll still walk you through each step to ensure everything goes well. 

Note: The process will vary depending on the model that you get. Consult your user manual to find out exactly how the process might work for you.

Using the control panel

Every projector has a control panel typically positioned on top of the unit. On the Viewsonic projector, the control panel will be in the lower-right corner and will look something like this:

To lock the panel keys, press the ▶ button for three seconds. A confirmation message will appear on your screen. Select “Yes” from the options to save your changes. 

Here’s another way you can go about the process: 

  • Press “menu” on your control panel and go to “System” then “Panel Key Lock”.
  • Use the up/down arrow keys to activate the feature. 
  • After the last step, a confirmation will appear – press “Yes” then “Enter” to save your changes.

You can do the same thing using the Viewsonic remote.

Using the remote controller

Depending on the model type you own, the buttons on your projector remote will vary. Usually, it will have the following keys and features:

The primary way to lock the control panel is through the native keys. However, there is another way you can lock the panel keys without standing up from where you’re sitting. 

That’s right – you can use your remote controller. 

On your remote, you’ll find a button with a 🔒 symbol. Press this button for three seconds, and the same confirmation message will appear on your screen: 

“Are you sure you want to lock panel keys?”

Select “Yes” to save your changes. 

And there you have it! Your panel keys are safe and secure from unwanted changes. 

Note: While it’s impossible for you to change the settings using your control panel accidentally, you can still unintentionally alter things using your remote controller. 

It’s best to keep your remote controller out of reach while watching a movie or doing your presentation. For instance, you could put it on a shelf, away from reach. 

How to Unlock Viewsonic Projector

When you lock the Viewsonic projector, it will remain that way — until you unlock it using the control panel or your remote controller. 

Even if you turn it off and then on again, the panel keys will remain locked. So, other people who use the projector after you might find it difficult to use the device. 

To prevent this, you should unlock the projector before turning it off. 

And here’s how you do that: 

Using the control panel

To release the panel key lock on your projector, you need to do the same thing you did when you locked it. 

Press the ▶ button for three seconds and release. The message that pops up will say, “The panel keys are unlocked”. 

After that appears, you’re free to turn off your projector using the remote or projector power button.

Using the remote controller

Meanwhile, if you’re trying to release the panel key lock using your remote, these are the steps to follow: 

Press the 🔒 button on your remote for three seconds, then release. The same message (“The panel keys are unlocked”) will appear on your screen. 

Do the same thing to turn off your projector: Use the remote or the power button on the projector.
