In the handset press
*331734# and the menu button, yur handset will be deregistered.

Enjoy unlocking :-)

here are some tips from my manual for out of range problems
hope they help
• Only one handset can be used to make or answer a call anytime.
If another handset attempt to do so, the screen will display OTHER
HANDSET ON and then OR OUT OF RANGE. You might press PHONE
or SPEAKER again until no other handset is using the line. Use the call
transfer feature to transfer a call to another system handset
or use the speakerphone feature so multiple members of your
house can be on an active call at the same time.
• Move the cordless handset closer to the base. You might have moved
out of range.
• Ensure that the base is powered up.
• Place the cordless handset in base cradle for 1 minute to allow the
cordless handset and base to resynchronize channels.
• If the cordless handset is in its base and the charging light does not
come on, refer to the charge light is off in troubleshooting guide.
• Reset the base. Unplug the unit’s electrical power. Wait for 15 seconds
then plug it back in. Allow up to one minute for the cordless handset
and base to reset.
• Other electronic products can cause interference with your cordless
phone. Try installing your phone as far away from these types of elec
tronic devices as possible: wireless routers, radios, radio towers, page
towers, cell phones, intercoms, room monitors, televisions, personal
computers, kitchen appliances and cordless phones.

Try this method:

Press locator button on base unit for 3 seconds. Now push flash button on handset for 3 seconds.

This MAY reregister phone to base unit. It did not work for me, more tests at http://www.panasonic.com/consumer_electronics/telephones/ts_guide1.asp

If your base is a VT2651:
1) take phone off of the base's cradle.
2) enter **335782 on the keypad
3) phone beeps
4) remove all batteries from handsets.
5) reinstall battery in 1st handset, and enter the code number for the base unit (sticker on bottom of base). First handset will be set to phone 1
6) repeat step 5 for all other handsets.

If your base is a VT2656, there is no keypad on the base. I don't know the trick to reregister the handsets. I wish I did, since that is the problem I am having.

from the troubleshooting section of the manual

• Unplug the base unit’s electrical power and remove the battery from the handset. Wait for 15 seconds then plug in the battery place the handset in the base unit and plug in the power. Allow up to one minute for the cordless handset and base to synchronize

not a guarantee, something to try

One has to completely deregister all handset by pressing end and # keys together till complete de registration is shown on handset screen. if the de registration is not done as above stated method the hand set will not register will show connecting on hand set screen.

Unplug the battery. Hold down The * (star) and the #(hash) keys simultaneously. Re-connect the battery, phone will beep and screen will be blank. Press the voicemail (righthand silver key under the lcd screen). As above EEPROM/RAM message will appear. Place handset on base and your problem is solved.

Registration:
a. Press MENU-6 to enter the registration mode
b. Press and hold the base’s Registration (REG)
button for 2 seconds until 4 LEDs light up. (Located on the base where you plug in the phone jack)
c. Press handset key “1”, this completes the
registration process. When you register the
handset to BASE 10, the base will assign a
handset ID between 11 and 19. The assigned ID
will be displayed on the handset LCD, indicating
successful registration.
d. Repeat above steps for all additional handsets.
e. The first two handsets registered will be given ID
11 and 12, which gives them administrator
privileges.

to re-register the phone, hold down the "handset locator" button on the base untill he "charge" light flashes. then, on the phone, hold down the flash/call waiting button until the LCD screen says "handset registering." if after it registers it says "error!!!" then retry. that is what it says in the instructional booklet, but i have not done this successfully. mine keeps saying error.
