Zanovo I?m not sure why you are still having trouble.
If you can get the SEC LED to stay solid then the virgin file is fine and the problem lies elsewhere.
So let?s start with the ECU in AUTO REG MODE...
Make sure you read the following carefully. The amount of flashes on the SEC LED in AUTO RED MODE when you insert a key tells us lots.
Once you have the SECUITY LED lit solid from the virgin file does the SEC LED blink once after each key is inserted?
Security LED SOLID >>>> Insert first key >>>> SEC LED flash once >>>> SEC LED SOLID >>>> Insert key 2 >>>> SEC LED flash once >>>> SEC LED solid >>>> Insert key 3 >>>> SEC LED flash once >>>> SEC LED SOLID >>>> SEC LED flashing (finished programming)
If you only want to program 1 or 2 keys you must press the brake pedal 5 times in 15 seconds after the last key.
If you don?t see the SEC LED blink at all after any key is inserted when in AUTO REG MODE then the "Key In ignition switch may be broken". The ignition housing has a switch to tell when a key is inserted (key does not have to be turned only inserted!) It?s very rare for this switch to fail but i have seen it once.
If the SEC LED stays solid after the 3rd key is removed or the brake pedal has been pressed 5 times then the vehicle is still in AUTO REGISTRATION MODE. The SEC LED will flash continuously after programming is complete.
Also
Are your keys definitely 4C?
If that doesn?t work error code B2796 means a fault with either of the following
* Keys (transponder chip)
* Transponder key amplifier
* Wiring Harness
* Engine ECU
