Question about Uniden TCX905 Cordless Expansion Handset
I originally bought this as a 3-phone pack, and added a 4th phone, and all was well. After a few years, 2 of the handsets went bad, and I ordered another set of phones to replace the bad ones. The new phones won't register with the old system, even though they are the identical system.
Do I have to completely replace my old system with the new one, and hope that the extra handset we bought originally is still working and will work with the new system? Any way to transfer all of my settings to a new system?
Ideally, I would love to just plug in two new phones to replace the bad ones, but I can't find a way to unregister them.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

SOURCE: Deregister lost or broken phones
Some tricks from a helpful Uniden rep:
holding down end+# keys at the same time on the phone for about 10 secs (you will hear a beep) will deregister the handset. If you have a dead handset and want to deregister it from the base, you have to reset the base. unplug the phoneline and power. hold down the "delete message" key, plug power back in. about 10 secs later, you will hear a long beep (theres a short beep upon powerup as well). At this point all handsets are deregistred and you will have to reregister them with the end+# trick. this way when #1 handset is dead, you can make a working one #1 and get the broken one fixed
BTW, this is a woot warranty, not uniden warranty. however the uniden rep gave me the number to the people who refurb (rox0rz!) these. I'll post an update when I finally get ahold of them (and the number if its actually helpful)

YOU might need to deregister the hand set first by holding down the red end (hang up key) and keep it down while holding the # key. If deregister wont work use base unavailable and yes, you are sure twice.

You need to reset the main base unit. Unplug the power from the back of the base. While the power is disconnected, press and hold the delete key while reconnecting the power. Wait for a long beep tone. When the display shows 88 or P, press play button one time. If you have a phone without an answering machine, disconnect the power from the back of the base, press and hold find hs button while reconnecting power.

On the base, open the menu and select Register Handset. The display should say Handset Registering.
On the handset you want to register, press and hold # until the handset display says Handset Registering (about 2 seconds).

In about 30 seconds, the handset display should say Registration Complete. Press Talk/fl ash and make sure you get a dial tone.
you don't hear a dial tone
the display says Registration Failed --
Making sure the handset is fully charged, then start over at step 1.

SOURCE: ADDING HANDSET SAYS OUT OF RANGE
A search of Uniden support only said to call 1-800-297-1023 with handset registration issues. The rep picked up quickly and walked me through the reset procedure. Here it is step-by-step:
1. Remove battery
2. Hold down the * and # buttons and reinsert battery. You should hear a long beep. If not retry. (This is a bit awkward but hold the handset upside down and it's workable)
3. Screen will be blank. Immediately press the right soft menu button.
4. Screen will report that EEPROM is clearing and then state EEPROM Clear Ok
5. Remove battery (yes again)
6. Reinsert battery (this time there's no need to hold down any buttons)
7. Handset will reboot with Welcome screen and then state that phone must be registered (this is the status a handset should be in from the factory)
8. Place handset on base and it will register as normal
