I used the Vag Tacho 2.5 program to program a new key for my 2002 Jetta. I am writing this in hopes that it will help others to get keys programmed without going to the stealership.
I am going to go over what I did to program my new key, If you follow these instructions, it is at your own discretion and I am in no way responsible for any negative consequences.
1. I ordered a spare key blank some time ago and it had been sitting in a drawer for a while. This is a key with an immobilizer chip, but no FOB.
2. I also bought a vag-tacho cable that came with the vagtacho program, it also had been sitting for several months.
3. I first needed to get the key cut. I tried 3 different VW dealers and ones key-cutter had been broke a while and the other 2 did not have a key cutter. They only ordered keys using the VIN that came precut. Inquiring I got info that a Valet key would be around $65 and a flip-key with new FOB would be around $165 plus programming ($ didn't ask).
To get the key cut I had to go to the AUDI dealership where I was there for a total of 15 minutes. The trace cut the blank from my only key for a total w/tax of $8.74.
4. After installing the program on my laptop, I plugged it the tacho cable and went to the car, Plug in the OBD-II plus into the connector, the green light on the cable will be lit. Start the Vag-Tacho program, after it is up an running, using your old key turn the ignition to on, but do not start the car.
5. On the program go to top, click on select ECU and put the check mark next to 'VDO New'
Now select the button labelled 'Connect Selected ECU'. I first got a message telling me 'Selected ECU Not Found! Try again or Select other ECU!' Going with the first option I tried again by clicking on 'Connect Selected ECU'. I had to do this 3 times before it finally connected and gave me an OK message.
6. After Connecting 'OK', There are more options that become available on the bottom buttons. I first selected 'Read PIN'. replied okay reading, my four digit PIN was revealed and I commited it to memory.
7. I then was ready to proceed with the programming of the NEW Freshly cut key. To begin make sure that the ignition is on with the OLD ALREADY WORKING KEY. Click on 'Program New Key'. A box will pop up with '0000' displayed where your four digit PIN gotten from step 6. I entered the PIN and did not change any other options. Erase all keys WAS NOT selected. The Channel defaulted to 21 so I did not change it.
8. Click on program new key, the program does its magic, my immobilizer idiot light was now flashing. The program then tells you to turn off the ignition, insert the NEW TO BE PROGRAMMED KEY, turn the key back to on, but do not attempt to start the car, Wait 5 Seconds. After 5 Seconds, my immobilizer light was off and I now have 2 keys that will start my car.
*****I originally started with the NEW KEY in the Ignition, I turned the key off and back on to program it. This ends up disabling the original key. I now had to used the NEW KEY and follow the correct directions to reprogram my old key, It worked flawlessly, without a hitch first time. **************
Hopefully this will help someone who like me was searching for this info and you will not have to do as I did and put pieces and parts from different locations.
Good Luck!!
