Difficulty programming unit. First had issues getting the module to learn the keys but realized I had low voltage. Charged battery and went through all steps up to 25 (towards end of CAN programming). At the end of sequence I received the blue light and it went off, then waited about a minute or longer, but never received the red LED. I've been through all steps including 1-12 and starting at 17, 18 and 21 but without success, have reset and resent data, but usually only receive flashing red. How can I completely start over as the unit seems not to fully reset after master reset and only get flashing red after going through 1-12 again. What process where should I start? Thanks.
