I have the base unit, 3 charging units and 4 handsets. All 4 handsets currently have "Place handset on Main base to register" on the their LCDs. All handsets are fully charged after 20+ hours of charging. When I place the handsets on the base to register the phone I receive a "Registration failed" readout on the phones. I have tried registering the phones in excess of 20 times for each individual phone. The handsets and base all have matching number formats (I'm guessing these are model, manufacturing and serial numbers). There are no buttons that will work individually on the phones (although the keypad will light up). I have also tried pressing the "end" and "#" keys simulaneously with no result. The base will answer phone calls on the intercom. Any assistance to activate the phones would be greatly appreciated. Thank you.
From any of the other phones simply press the MENU button go down to SYSTEM RESET and hit SELECT. Then choose Deregister HS and choose the one that is giving you the problem. Once deregistered, place the phone on the base and it will now register.

I do not have a system reset option either on the base or the handset. I tried the eeeprom delete thing and that did not work. THere is no option to deregister the handset either

I had a very similar situation and I did solve it. You have to have at least one phone that is correctly registered. You press "menu", go to "system reset" (press "select" key), go to "Replacing base" (press "select" key), go to yes (press "select" key). Now all of your phones need to be reregistered, but that worked fine for each. Apparently it has to release all of the old registration data before it accepts new phones. As the other user (and I followed his advice first) said, good luck in solving your electronic problems.

I had same problem solved it using above instructions and after clearing EEPROM. Here's what I did;
Using one phone that is correctly registered.
1) Press "menu" --> "system reset", press "select" key
2) Choose "Replacing base", press "select" key
3) Choose"yes", press "select" key.
4) Placed HS ( the one that I used to replace base) on the base. It successfully registered in 10-15 seconds.
5) Placed HS that I had problems registering on the base. Bingo! It registered in 10-15 seconds.
6) Checked my other two HS and I did not need to register them.

I have contacted Uniden about solving this problem. They suggested I clear the eeprom on the handsets and reset the base. To clear the eeprom detach all of the batteries and reattach while holding the star and pound. You'll hear a beep. Press select and the unit will clear the eeprom. Now hit end and the unit will say "Welcome...something or other". Next unplug the base unit reattach while holding delete. Next hit delete twice...the base is reset. Apparently this is the last possible solution to marrying the handsets and base. This didn't work for me and the units have been declared dead. Good luck in solving your electronic problems.

If you are having trouble getting a message Registration Failed you may have to deregister an old handset no longer in use to make room on the system for the new handset

Usually answered in minutes!
my phone keeps saying sim registration failed i don't know why because it was working perfect before. but i think was playing around network settings.
The base unit is showing an error code E1. I can't find anywhere in the handbook what this stands for or what to do and of course it is a weekend and Tech Support is closed. I have unplugged it and waited an hour before plugging it back in. It still reads the same code.
i have 2 phones uniden2.4 with 3 phones for each base i accidently put one phone on the wrong base it now says phone number 4 it actualy went to the other base. how do i get it to reprogram to the base it belongs to?
I followed the "best solution" which worked for me. Although on my model phone the eeprom reset did not follow the routine as describe. The part that did work however, was unplugging the base unit, then holding delete and powering it back on again. It beeped. I hit del a couple of times and then put the phone back on. All good! :)
Cannot make or receive phone calls on either handset. Dials the number and then cuts out, I made a call about midday today and it worked ok.
handset #2 was disconnected over night, when I reconnected the next day, phone displayed "searching". and then displayed "handset out of range" how do I re-register onto the base?
I have misplaced the manual therefore do not have the pin required to register the handset to the base unit.Plz help.
All the other 3 handsets registered without incident the forth won't regester
I want to register a handset to the base of my uniden dect 6.0 cordeless phone
Uniden handset will not register two other phones work this one phone says registering and then shows registration failed
I put the handset on the base and the message says unavailable
Base unit does not turn on. Handsets say searching
THe base unit is unrepsonsive. The phone is fully charged and responds to key presses in the normal fashion.
charged headset and led is blue when headset is in charger. When taken out it flashes red then blue, alternating between red and blue
I have tried pushing reset button and no change
headset wont register and useless uniden instructions tell you nothing about trouble shooting
