What is Launch X-PROG 3?

Launch X-PROG 3 is an advanced immobilizer & key programmer, by working together with X-431 series diagnostic scanners (X-431 V, X-431 V+, X-431 PAD V, X-431 PAD VII, etc), it can read/write keys to the vehicle, it can perform immobilizer identification, Remote control matching, Key chip reading & matching, immobilizer password reading and immobilizer component replacement etc.

Look at this images for X-PROG 3 supported brands, supported systems, compatible X431 diagnostic scanners and functions (i.e BMW CAS module clone, BMW 8HP clear ISN, Audi transmission clone, MED17 ECU clone and more…)

Good to know:
– X-PROG 3 in gray color: available online eshop like;
– X-PROG 3 in red color: available in offline dealership.

Today, we will test one of its core functions ” Audi A5 TCU Clone with Launch X431 PAD V and X431 X-prog3″.

Operate in normal method:
Get security code
Get used transmission security code
Make replacement step
TCM programming
Coding, basic setting…

Why clone?
After replacing the used transmission, perform a TCU CLONE may help you skip all security, programming and coding steps. It will effectively improve work efficiency and save working time.

X-PROG 3 Key Immobilizer & X-431 scanner Pad V will help you to quickly complete the entire operation process with ease.
