I think its not a button, its a switch, look around player and you might see it. look for the symbol that signifies lock and unlock.

Python 476p

May depend how it was programmed. My Python 476P was setup with Lock and Unlock pressed to get it to remote start. Then, get in the vehicle, put the key in the "on" position and press lock / unlock to get it to end the remote start cycle. Then Drive off ...

I got a second remote, followed some directions via YouTube to program. Key in the on position, then hit the valet button once, then press and hold. One chirp, hit lock on remote. Let go of valet button . Press, then press and hold, two chirps. Hit unlock. Continue for 3 (aux) and 4 (panic). End result was Lock would also unlock. Unlock did nothing. And Aux started the remote start sequence.

Having bought a vehicle used, then no manual made this a bit difficult. I will continue to test alternate programming to try to match the original remote so accidentally firing up the rig doesn't happen. My suspicion is I have to maybe do Lock, Aux, Lock/Unlock, panic instead. Good luck.

I accidentally unplugged my iriver e100 from my computer when it was doing a firmware update. now it stays frozen on the main screen!! Plz help!! D:

on the side of the mp3 player above the lock switch is a very small reset button. it can be pressed using a paper clip, a safety pin, the post of an earring, mechanical pencil led, or something else of similar width and length. press and hold this button until the screen goes blank. it may turn back on itself, or you may need to manually turn it on. it should be fine now.

My mp3 player has locked up and the "HOLD on" Message is on the screen nonstop. No matter what button I press it won't go away.

There is Hold switch on the right side of the player. It locks out the keypad to prevent accidental pressing of buttons when you are enjoying music. Its like the mobile phone keypad lock.
Turn it off by sliding the switch. .

Sprint htc touch pro 2 - will locking prevent accidental dialing or does it have something to do w/the backlight,,,every couple min. phone lights up and then the buttons are too easily accessed leading to...

locking your phone will help stop accidental dialling. if you don't lock your phone all you have to do is touch the screen and your ready to press buttons if you lock it then you have to unlock before you can press them, so in turn to acccidently call somebody it would have to unlock itself in your pocket.

My son's digital mp3 boombox is locked. How do we unlock it so we can play the music?

After much frustration, I've figured it out something that works.
Turn the mp3 player off, remove the battery cover, take out the batteries, put them back in, screw the battery cover back on, turn the mp3 player on, press the green play button. You should then see the "welcome" screen.
The boombox has continued to lock up frequently - almost everytime my son plays with the stinkin' thing - but at least I know how to unlock it now.
Good luck :)

My controls are locked

If you accidentally pressed "Heated Dry" for 3 seconds and it locked your controls, just press the same button for 3 seconds and it will unlock.

Proline locking issues

The Proline manual (comes on a CD with the player) says:

6.3.7 Key lock
This function sets a time delay from when key lock function is started or the player is switched on, after which the player will automatically stop responding to the control buttons. Pressing any button will then display the message ‘Locked’. Key lock is useful, for example if you put the player in your pocket and don’t want any buttons to be pressed accidentally. The time delay is to let you start playing the music and so on. You can choose a delay of ten or thirty seconds, one, three or ten minutes, or you can disable key lock completely. •
Press and hold the V+ button for a couple of seconds to temporarily unlock the keys.

Ilo mp3 player

On the top of the 1GB one, there's a switch to turn it from "locked" to "unlocked". This is to keep from accidentally hitting a button while listening to it.

My player won't turn on!!!

The m25 will not power on if LOCK/UNLOCK is in the locked position. If you press the POWER button, a padlock will appear on the LCD to remind you that the unit is locked. Confirm that the LOCK/UNLOCK switch is not in the locked position and press POWER to turn it on. If nothing happens after pressing the POWER button, the battery is probably discharged.
