I am able to RESET System3 without any problems, but when I try to then DEL + System3, nothing happens (no beep). If I then simply press System3 while in SYSTEM teach mode, I see it run through the POWER ON factory presets (so I know the preset factory code is still in use).

I have tried to RESET System3 several times, and then DELETE System3 with no luck.

I have already programmed System1 and System2 without any issue. Not sure why I'm having this problem now (in the past, I was able to reset and delete and then program all 3 of these hard keys).

Thanks,
Travis
