I got a little ht that is giving me fits. I tried to turn it on the other day and it would not turn on. Took battery out put it in another vx5r I have turned right on put external power to it still no luck. Put it aside and a couple days later I put battery back in turned right on turned off and on 5 or 6 times no problems. Now the key pad does not work it does not show it as being locked but I can't use key board to try to unlock if it is locked. It won't let me reset it so I am stumped

any input would be great.
