Keri K Fobs
Recently, I have been playing with some keri K Fobs with indala encoding. Since no one has solved it yet, I will share some of my findings.
If anyone has a Keri access control system, let me know. Let's see which is the next byte for the serial number so we can properly predict it.

Re: Keri K Fobs
there appears to be a typo in 3260898 - 64116BE57, but then binary says 64115be57 and second hex says 64117be5f and third hex says 64115BE5F. 3 different hex?
i believe the binary to be correct at 64115be57

Re: Keri K Fobs
why doesn't the first column of hex (marked indala coding) match the second column of hex (unmarked)?

Re: Keri K Fobs
I was trying to guess the pattern. To see whether both matches when i do the decoding. Bad with numbers. Had some mistakes here and there.
