Can't get "handset lock" to turn off.

I guess you mean the Keypad Lock/Unlock!

You can turn on the keypad lock of a handset.
In idle mode, press * button and then LOCK to turn on the keypad lock. "PRESS UNLOCK TO USE KEYS" is displayed on the LCD.
In keypad lock mode, press UNLOCK to turn off the keypad lock.

Turn off your device and press the volume down key.

You will then press and hold the power button until an Android interface appears.

Press the home button and choose DELETE ALL USER DATA.

It may take a few minutes, but your device will reboot and be unlocked

Which specific Uniden phone do you have? On the Uniden D1780, pressing the volume down button several times will turn off the ringer. With the phone in Standby, press the volume up button.
A different model, the D2180, has a Do Not Disturb button on the base. Press the button to allow the handsets to ring.

Other models toggle on and off the Silent mode by pressing and holding the # (pound key). I think it takes 3-5 seconds for the key to toggle the mode on or off.

Most manuals for the Uniden phones are available here: http://www.uniden.com/owners-manuals/cordless-phones/scat/cordlessphones_mnl . Use the drop-down menu to select DECT phones, if you have one of them. The manuals are listed in alphanumeric order. Ignore the suffix; the manuals are the same even when the phone was sold with more handsets.

I hope this helps.

Your remotes may need to have batteries replaced and re-programmed.

Hold down the asterisk key, not the hash key.
