I am new to this forum. Have Jetta TDI 2002. Frequent short distance driving 1.5 mile one way. Lost battery power in a cold morning and the Immobilizer light flashing since than. Charged the battery up and left the key with the ignition ON for more than an hour /three times/. Immo Ligh still flashing. Later took the flip key plastic apart /only one remote key/ and found broken greenish small glass pieces inside. Later discovered it was the transponder chip shell broken. I am DIY person, so I ordered an uncut key with integrated new transponder chip and need to know how to retrieve the SKC and program the transponder. Third owner of the car and this was the only key I have. Please help!
