OK sorry guess I was thinking you had 2 handsets.
My suggestion is go to the Uniden website and maybe see what they have there.
Maybe do a search on the Uniden site for that Automatic Digital Security Code thing, seems it would be easy to fix, just a matter of how....
In the meantime I'll do some searching and see if I can help and find a fix

SOURCE: Phone won't hang up
I solved this exactly problem by doing this:
1) unplug base station from phone line
2) unplug base station from power cube
3) open each phone and disconnect battery (do not replace phone in charger; just let it sit)
4) wait 30 minutes (per instructions from Uniden)
5) reconnect batteries in phone sets
6) reconnect power cube to base station
7) reconnect base station to phone line
8) test: make a call. Hang up. Wait one minute. Pick up line and see if you get a dial tone.
(Basically you're "rebooting" the system. You don't know where the fault lies, so you power down every component to make sure you get it. The '30 minutes' is longer than I'm used to, but after being on hold with Uniden tech support for 20 minutes and finally getting through, the instructions from them were very clear: AT LEAST 30 minutes. OK! I did it - and it worked!)

This happened because there are too many phones sharing the same line with no power amplifiers.
Your phone line is self powered by a small current generated by the phone company (that's why old, wired phones don't need a separate power connection to ring or make calls, it's enough to just plug them in). Each phone you connect to the same line acts as a resistor and drains some of this current. Eventually not enough power is left to carry the signal.
The phone company technician can fix this by installing power amplifiers.
In any case, I would test this theory by unhooking all other phones and checking the cordless ones on their own.
If they work fine, call back the phone company and ask for a "real" repair person..
