connect your upa with external power supply ? short the buttons so you dont need manually press, for accuracy.

I put a little low melt solder on the other side of the switch, and remove with desoldering wick.

Hi guys, good evening.
Im getting some info about Merc keys.

- I wonder if, is there any way to know which mcu the key has?? I mean knowing just for seeing which ones are motorolas mcu, and which ones are necs mcu.

- Are these motorolas dificult to open?? have to cut or break the two sides?? (never opened one before).

- These motorolas mcu, together with upa, can just read original working key and write into a virgin or used one ?? will it work?? If its an used one, will just overwrite existing previous data??

- How is the chronology on these?? I mean (just an example) motorolas are from 2001 till 2007, and necs are from 2007 till 2012, or how is it ???.

Thanks if someone can explain these points.
Thanks in advance.
Regards

All the big black "fish" keys are motorolas. Smaller black keys and Chrome keys are NEC. simple
