I have had this happen on a 3500 and I had to replace the keypad assy. But, you may want to try to restore factory settings just to see if it resets. Disconnect the battery pack and hold down any number key for 10 seconds (this bleeds off any charge that may be in the capacitors). Reconnect the battery and within 3 seconds, press and hold the "A" key. After hearing 6 beeps, release the "A" key and wait for 5 seconds for the lock to re-lock (listen for 1 beep and red LED).
If successful, this will reset factory settings, which means the master code is now 1 2 3 4 5. If you need a programming manual, go to At the top of the home page click on "support". Scroll to the bottom of the support page and click on Technical Library. Scroll down that page and find "trilogy DL programming manuals" and under that click on "download DL2700 enhanced instructions". I hope this is some help!

Pegasus handle without lock has locked

before you put it together are you able to turn the nob with the return spring in it? I may be that you have the shaft going in the wrong side. Turn it and try it without putting it in the door. One way it will do as you are saying and when you turn the shaft 180o it should work.
