Segway i180 button keys

[[email protected]]

None of my keys have 6 zeros.

And the entire "functional" code for the Segway is 32 hex digits - of which 16 are the key code, as you said.

[MagiMike]

Here is the key code for an "old" key to a seg, I no longer own.
50 78 10 0C 16 9F 16 5F 21 20 15 45 A3 19 00 B0
As you can see- there is no six 0"s sequence.

Your questions are all good and have helped us expand the knowledge base.
Keep up the good work.

Hi,
I got some of the keys I have ordered for specific chassis I have.
I did not check them on the device I had ordered it for, since it is not in working state currently.

But I did take these 3 keys and could reprogram them to different chassis.
First I did exact copy easily.
Then I tried to take the black key - and produce from it the RED one, I took from the SW the ROM number, which did not work for me.

Then I realized that I just need to open the IBF file and take the 16x 2 hex bits to new file, and change specific fields in order to change speed, this did work for me!

So I don't understand the part with CHECKSUM, do I need it?
It worked just find with this tool:

http://www.segwayoc.com/key/key.php

when entering the IBF from the start of my file of the black key


Also Segway company reproduced my keys by chassis number (which is 12 decimal digits) - I am sure that they don't have a database of the digits and key code - meaning there is some Math way to convert the 12 decimal digits to key code, I am pretty sure about this,
Did any one here - try to figure this out? or found something ?


Thanks,
R

That software computes the correct CRC to work with the bytes that you changed. It's my understanding that if you just changed the bytes that control the speed, turn, etc. and did not change the CRC code, then the Segway would not accept the key. I've never tried that, but please feel free to do so (without using the software you just quoted) and let us know the results.

Why are you sure of that? Is there some reason that they should not (or could not)?

As I have understood from other forms, if using the default where:
CRC order (1 to 64) = 16
CRC polynomial (hex) = 8005
Initial CRC value (hex) =0
Final XOR value (hex) = FFFF

I believe the last 2 values determine no CRC ?
So just need to change the speed values at the correct windows (and this is done by the SW)

About 12 digits - this is related to some encryption - that could be easy (or not) for example multiply the number by fixed value (can be many other things)
I think (may be just firing in air to wrong direction) - that this is done by some calculator they made for it

Long ago, from people I believe, I heard they did have a database with the key codes for each machine at the factory.

That may have changed, but at the time the factory was producing 180s, and I was friendly with the chief technical officer of Segway, I was told the database existed.

We never did have an in-depth or detailed conversation about it however, nor about how the database was populated.

I am not sure what you mean. The CRC must change if you make the speed setting or the turn setting or the golf setting different. Yes, the CRC calculation software does that - but you cannot simply change one of the values without also changing the CRC.

I believe you are not correct about that.

But I am quite willing to learn something new, and I have two XTs and know the key codes for them. Just figure out the method of getting the key code from the serial number, let me know, and I'll test your method.

If you have two machines and know their serial numbers and key codes, can't you extrapolate the formula to convert one to the other?

I always thought there was more to it than that. The serial number of a machine is in large part a date and sequence number, yet the key code comes from the chip set on the main boards. Since the boards are manufactured before the segways are assembled, I can guess that the serial numbers are created and assigned after the key code already exists. So for this reason, I do not presume you are correct as to them being related.

But if you are, and you have serial numbers and key codes for several machines, it looks like you are in for some code breaking....

I have two machines, and I cannot see/compute/guess/divine any relationship between the serial numbers and the key codes.

But it's curious1 who asserts that there "must be" some formula.

I just offered to confirm it when he provides it.

You are quite right. I saw curious1 quoted statements in your posting, and inappropriately used your post to hit the quote key from instead of his...

I was addressing Curious1.

Sorry for the blunder.

And my statements that I do not feel the key code and the serial number to be extrapolated from the same point remains. I think the key code exists for a board/key combination long before the serial number exists.
