Need a model number for what remote came with my GT2015DV

Turn on the TV and grab the remote. In most cases, you will need the original remote to unlock the TV if you aren't sure of the unlock code. If you don't have the original remote, you will need to purchase one.
Look at the screen. If you see a blank screen with a red key on the bottom of the screen, press 'Function' and 'Mute' at the same time. This should unlock the channel. This is an option for people who want the TV to stay locked but, want to be able to bypass the lock to watch a certain show or channel. All other channels will remain locked and the TV will fully lock when it is turned off.
Unlock all of the channels on the TV by entering the factory reset code. There are three main reset codes that TV manufacturers set. These are 0711, 6688 and 3308. Try each one until you find the one that works. This will reset the TV to original factory settings. When you do this, you will loose any information that you have stored in the TV, such as favorite channels, automatic timers and the clock. You will have to go through the full initial set up.
Call the technical support service number in your owner's manual if none of those codes work. A technician can help you troubleshoot the television because the problem may not be the locking control. When you call, make sure that you have the model number and serial number of the TV.

Take your television to a TV repair shop. In some cases, a professional who access to wiring diagrams for your television set may have to rewire certain components in order for the television to unlock. This is usually the case when the TV locks by itself while it is on.

Pull up previous posts by its left sidebar, or type in the brand name and model number to of your set, to its search box, and press 'Enter' or view it in Mosaic / Timeslide option.

Google the model number for remote (original only) or call Vizio for a replacement.

Omni TVs have a child lock that allows parents to prevent children from watching specific channels or television shows with certain ratings. To activate or deactivate the controls, you need the four digit pass code. If you forget the pass code or if the lock gets set accidentally, you can still unlock the TV.
• Use the original Omni remote control to turn on the TV. You need the original remote to bypass the child lock. A universal remote won't work.
Check the screen. If you see a blank screen with a red key on it, press the "Function" and "Mute" buttons at the same time. This unlocks only the channel that is on the TV. All the other channels will remain locked and the TV will lock again when it is turned off.

• Unlock all of the channels on the TV by entering "6688," which is the factory reset code. This code resets the TV to original factory settings. Once this is done, you will have to go through the initial setup.

• Call Omni technical support at (416) 260-0047. A technician can help you troubleshoot the television as the problem may not be the child lock. You'll need to know the model number and serial number of the TV.
•Take your television to a TV repair shop if you are still unable to unlock the TV. The problem may be with the wiring, so the repairman may have to rewire the TV

You need the original remote for this and Apex parts almost do not exist

Something is wrong..crbr799 your DVD-TV has a TV-DVD button on the right front to switch from TV to DVD play...OPEN button on left side ,place DVD in tray, close & press PLAY...
I something simulator that needs the remote control for the SPECIAL functions....by the way the ORIGINAL r\c is $135 to $155, a replacement ($35) will turn the TV\DVD on ( which you can do without the r\c) and NOT function with anything else.
P.S. they will try to sell you universal r\c that work with the CABLE boxes, the ones that you pay a monthly fee!!

Hello
Try the following to unlock your Jensen TV.

1. Turn on the TV using the remote control. In most cases, you will need the original Jensen remote to unlock the TV if you aren't sure of the unlock code. You can purchase an original replacement online if necessary.

2. Look at the screen. If you see a red key on the bottom of the screen, press "Function" and "Mute" on the remote at the same time. This will unlock the channel. Do this if you want to bypass the lock to watch a certain show or channel while leaving the TV locked. All other channels will remain locked and the TV will lock again when it is turned off.

3. Unlock all of the channels on the TV by entering 0711 or 3308. These are the Jensen factory reset codes that will reset the TV to the original factory settings. By doing this, you will loose any information that you have stored in the TV, such as channel labels and schedules. You will have to program the TV again by going through the entire initial set up.

4. Call the technical support service number in your owner's manual if neither of those codes work. A technician can help you troubleshoot the television as the problem may not be the parental lock feature. Have the model number and serial number of the TV available when you call.
5. Take your television to a TV repair shop if neither of the codes work and the TV locked by itself while it was turned on. In this case, the TV may need to be rewired.
OK.
