HELP: T300 KEY PROGRAMMER

[strikeforce2]

Please I need help on modifying the obd2 cable and pinout for T300 to read pincode from immo box on the bench and program a new key.I saw this video on youtube.
Actually a customer lost his key and I wanted to make a new one but the immo box is mcu and I had a nasty experience resoldering it back after sucessfully reading the dump using xprog which was also verified as a good dump but the vehicle could not start apparently due to poor resoldering ( I do not have quality stuff for that only china made which made the situation worse ). infact I lost moneyon that job and from then on I had to take similar job to a loclsmith who barely left me with little profit from the job.

Most of the cars around here are old with tempered electrical wiring and therefore diagnostic port is not communicating. the only way is through the dump and I am not good with mcu so I am trying to use this guy's method. I believed he modified one of the cables for T300 and btw he read the pincode with the T300 before manually inputting it. I had a golf mk3 immo with 3D33J mcu 2 days ago and the locksmith programmed the key successfully without unsoldering the mcu chip and the car was 100 km away, I only gave him the immo box, but he squeezed me dry without making any profit on the job. that is what make me went searching and apparently came across this guy's video. I requested info from the guy, he hasn't responded yet.

my friend if want be in this job you must have contact with chips and mcus for sure. some mcu like 3d33j from vw immobox can be read incircuit with wires, some can't. be ready to thousands of dollars of investment in tools and a lot of risk. simply, this is a job.
