How do I unlock smart lock, I have the remote, but I don't know the 4 digit access code

To open its child lock, you might have its original remote control. Try these methods. Locate the manual for your television. Though slightly embarrassing, accidentally turning on the child lock to a TV is a common problem. The section In the manual about how to set the child lock feature will also explain how to unlock it.
Try a few "universal methods" for unlocking the child lock. Some televisions have a universal code built in for disabling the child lock --no matter what your code is. A common code is "0000."
Unplug your television for a few minutes. The internal battery of the TV is what helps remember what your code. If the TV is unplugged for an extended period of time, it clears the internal memory, which in turn will reset your child lock code.

I called Philips Magnavox at 1 888 744 5477 and they told me the default ACCESS CODE number is 0711. It works on my TV though it didn't solve MY problem of the TV defaulting to Chanel 9 every time I turn it on. Drats. Hope this helps.

do you have a 3 digit code for RCA TV for the philips universal remote?

i am lookin for codes for a magnavox. i have a access 4 remote one in all.

Try 0711 as your default code, you may have to enter it twice...Let me know.

A model number for your Magnavox TV would be helpful because the Parental Control Reset procedure varies. There should be a sticker on the back of the TV showing the model number. If you have a newer LCD model, the unlock code is usually 0711. Ignore any "Incorrect" warning and enter 0711 again. Then set or clear the Parental Access Code.
