Guys, we have a slight language barrier here as his location is Austria, as in they speak German, Slovenian, and Armenian. His syntax seems more towards the Slavic languages like Slovenian or Armenian as opposed to Deutsch.
We probably should give him direct links to items as he may not be able to get them in Austria.
Here is a scan tool that can do everything, and is in German.

German, got it and explains things.

Security only check.

Clean the key’s resistor “pellet” which is the silver line in the black insert near the end of the key with a clean pencil eraser or fine steel wool(both sides).

Clean the VATS “reader” which is the two contacts just inside the ignition key hole. Use a bit of isopropyl alcohol on a Q-tip and clean just inside key hole to remove any dirt that might be on the contact(s) preventing a connection to the resistor pellet. Inspect the Q-tip, and if dirty, repeat until clean.


Fail Enable: This mode is to help keep the motorist with the right key from being stranded. If a failure happens to the PassKey system AFTER a valid start, this mode is initiated. It allows the vehicle to be restarted, even with a failure present. The security light will remain illuminated to let you know a failure is present. However, this also means that the car can be started w/o a key, and is vulnerable to potential thieves. If battery power is lost while in fail enable mode, this mode will be lost and the next attempted start w/ the system malfunctioning will cause tamper mode.

As mentioned, if the security system is in "fail enable" mode and you ever loose battery power, or simply disconnect the battery, the engine will not start on the next attempt, unless the problem is corrected. If that happens, it may be time to bypass the key reader. The link below will explain how to do that.

update:

because the last time i was boring, i dismantle the covering under the dashbord and remove the glove department to check the lines of the pass key. i have discover nothing........................but ................the bypass is directly connected on the pass key module, the resistor is the same like the key. i have checked all lines and now the security light works like it should be.
apparently it was a loose connection, from the bypass.
