By-the-way: In this case there are even more than 20 F's in the protected code, and besides also lines 70 and 90 contain code too.

Thanks for your reply Chris. I understand that without the EcuVonix software or some other kind of special softwaretool it can't be done. Taking in account that in a code with more than FFFFFFFFFFFFFFFFFFFF (20 x F hex) as a maximum number that already means at least 1.2089258196146E to the exponent of 24 of decimal possibilities. And because also other special characters could be used that even widens the number of possible wrong codes. Whithout any given method or algoritmic explanation the article only tells us that it is impossible to do this with just a Hex editor? It is just like hacking the Eeprom of a protected Lithium Battery without any expensive software tool. Also impossible (luckily they now sell Lithium-ion BMS charging boards without time and charging counting Eeproms, See for instance: https://nl.aliexpress.com/item/4A-5A-PCB-BMS-Protection-Board-For-4-Packs-4S-18650-Li-ion-lithium-Battery-Cell/32656147875.html?spm=a2g0z.search0104.3.9.6Rkkq5&ws_ab_test=searchweb0_0,searchweb201602_2_10152_10151_10065_10344_10068_10342_10343_10340_10341_10084_10083_10613_10304_10615_10307_10614_10301_10059_10314_10534_100031_10604_10103_10142,searchweb201603_25,ppcSwitch_5&algo_expid=8cb5460d-4e34-4c5f-a426-ef5d2e57380d-1&algo_pvid=8cb5460d-4e34-4c5f-a426-ef5d2e57380d&priceBeautifyAB=0 ).

Hi!
Thanks for supporting my article.
So, it is a different story.
You must program a new transponder ic.
I'm not sure but I think the so called ZedBull device can make a copy of your key.
But SBB can for sure.

I think, it is more worth to make the immo off in your car if it is an acceptable solution for you.
I think in immo off direction because if you need to buy a programming
device + trnasponder ic (several pcs.) that will be to expensive for only one car. Maybe if you go to a pro person would be a bit cheaper but the most cheap and 100% working solution will be the immo off.

I hope I helped you.
My best regards.

ChipQuik Alloy is a very good think and I like that product, but it is very hard in my area to get one...

Hi!
Thanks for supporting my article.
What type of alarm system is it in your Pontiac?
What model, year is that Pontiac?
Is that alarm system a OEM system in that vehicle or an aftermarket?

Just for info:
The immo system and the alarm system are not the same think.
In modern cars, that two systems are close the same but still not the same think.

My best regards.

Hi!

Here in my areal the insurance have nothing to do with this mod.
If you do something like this, you should agree the consequences with the law.

My best regards.

Hi!
Thanks for supporting my article.
I assume you have that Sagem from some type of the PSA family of car and the name of the ecu is actually Sagem S2000.
I also assume you wish also do the immo off.

In this case you could have the eeprom 25080 or 95080.

You have to read out the eeprom and follow my text but don's short out anything as I described.

Also follow the instruction from EcuVonix.

My best regards.
