Lloyd,
Do you have the 2 diodes to permit using a hand key in addition to
paddles (auto-detect)?
If so, try removing the diodes to see if it works - Turn off auto-detect.
Do you have a microphone connected? If so, remove it on the possibility
that there may be a mic problem with the PTT switch.
If no diodes, put a 1/8 inch stereo plug in the key jack and short
across the tip and sleeve contacts and then across the sleeve and ring.
See if either the dots or the dashes become extended. If not
investigate the external cable(s) to the paddles.
If you have trouble with just the stereo plug, the next suspect is the
key jack - although they seldom fail (I have only 2 in all the K2s I
have serviced), that is the least expensive possible fault.
Eliminating the above as a problem, the only thing left is the firmware.

This is the weirdest thing ever.
So my wonderful K2, #4442, was pressed into service once again, a few
months ago, after some needed TLC from Alan Wilcox.
All was fine. In fact, it was all wonderful!
So I just built a new antenna; got it up yesterday, it's a 40M full-wave
Delta Loop. Hoping for some DX.
Early last evening, I got some plugs on the end of the feedline, and
connected both antlers to the rig. After comparing received sigs, I decided
to call CQ, and compare RBN results. But someone replied, and I began a
QSO.
That's when this trouble began. I was unable to send intelligible code;
extra dits were being inserted. I tried changing menu settings, fiddled
with the key. I finally had to just bag the QSO and go QRT.
This never happened before. Whether operating, or in test mode, the keying
is intermittently whacky. It will sometimes send a couple or five extra
dits. In HAND mode, it will extend dahs, randomly.
