Questions and answers

Is the X100 PAD3 worth it over the X100 PAD2?
The PAD3 adds an 8-inch HD screen, bi-directional control, ECU coding and the KC501 key programmer. If you do VW/Audi MQB or FCA CAS work, the hardware jump is the main reason to pay more.
Does it program keys for all brands?
No. Its immobilizer coverage is strongest on VW/Audi MQB and Chrysler/Dodge/FCA CAS1 through CAS4. Check the vehicle against XTOOL's coverage list before buying for another brand.
What is the KC501 and is it included?
The KC501 is XTOOL's key programmer, and it comes in the box with the PAD3. It handles key chip reading and writing for supported vehicles.
Which FCA vehicles does it cover?
FCA support starts with 2018 and newer vehicles. Older Chrysler and Dodge models fall outside the listed coverage.
Is $849 a good price?
That is the best new price across the three stores listing it new as of November 5, 2026. Compare against the recent range before buying, since pro tools like this move in price with bundles and promotions.
