You confuse me, the keygen you are talking about is the so called gk_mod based on JM KG 1.3, which generates an unlock code with experation date.
For example PID 1527 generates a a code valid till June 11, 2023.
And I cannot agree that you keep this KG for a single board, especially when its available through various sources (incl. me)

I don't know gk_mod. I also never use JM keygen. I am talking about generating of key generator knowledge.
Also, you need to know Date field and PID field is different field. Do not mix it.

There are 8 fields to compose a key.

This generator is called DeEn. DeEn had never been and will not be public.

Well if it is not and will not be public, and it seems you are not going to share it with members, why bring it up to this forum? Why post the information if only you will be able to access it?

Then I guess it's fine that I post the gk_mod.
The above program seems to be based on the Excel file which was delievered with the gk_mod to generate valid ID's for the week numbers.
Don't know why u need a key for Thailand, its free and proven working already without key.

Just to state it clear, the gk_mod generates only expiry dates for US traffic, no other country

You are wrong. Free traffic doesn't mean that don't need subscription code.

Ask those people who use GTMxx (not the one selling locally), will it work or not?
I do explain it here. [Only registered and activated users can see links. ]

rem...
The above program is not Excel base. It was written with MS Visual Basic. DeEn is a stand alone software.

Don't wanna argue with u, but several people already confirmed they receive Thai Traffic after updating the "TrafficProvider.xml" v2.70. This is only confirmed for GTM25/35 and Nuvi 1xxx and 37xx series.
Regarding the Excel file, sorry that I didn't state that clear.
There was an Exel file which calculated based on dates the week numbers, the result was the same, 4095 was the highest limit to generate a subscription key which expired in 2079 (which should be enough).
I can understand the motivations, but on the other side, I see programs and information on SM shared, which are from other communities.
My modifications to make a Thai version of GMXT would be an example, even I could not access the downloads necessary on SM

It is useful when the map content expires and you want to remind map user that a newer version should be used instead of expired. Jetmouse has intentionally set Expiry period to Never, which is no good for my plans. gk_mod seems to offer solution for this problem. Right? Thanks!

That would also be useful to generate keys for AD-Free NAVTEQ traffic. There used to be a MOD version for extending the expiration date for the old trial versions on TTN. The filename was "jmgkg13modTMCExp.exe". Unfortunately, you could only enter a code to control the expiration date (adds in week increments ) but the FID was hard coded to use 28992 regardless of which product was selected from the dropdown list.

Reverse Key Example of what it did:

---------------------------------------------
UNLOCK KEY : N954Y-5MA2T-EVQ5R-ZXVAH-PXVEY
---------------------------------------------
KEY IS VALID: YES

Unit ID : 1234567890
Family ID : 28992
Product ID : 0
Region ID : 0
Vendor ID : 1
Date expire : 26.06.2079 (week: 4095)
Product name: TMC:Total Traffic Network (USA) lifetime subscription
