What the XP400PRO Does

The XP400PRO is a key and chip programmer that connects to a compatible Autel MaxiIM or MaxiSYS tablet (via USB) to extend the tablet's key programming capability. It is primarily used for:

• Key learning and programming — program new keys to vehicles, including all-keys-lost scenarios on supported makes and models
• IMMO (immobilizer) functions — read and write immobilizer data, reset IMMO systems after key replacement or ECU swap
• Transponder chip reading and writing — read existing chip data and write to replacement transponders
• Smart key and proximity key programming — covers modern key fob and push-button start systems on supported vehicles
• OBD and non-OBD key programming methods — accesses IMMO data via OBD when available, and via direct connection to the vehicle's IMMO system when OBD-level access is not sufficient

Why the XP400PRO vs. the Standard XP400

Autel offers multiple key programmer accessories — the XP400PRO is the advanced variant with broader chip support and additional IMMO functions compared to the base XP400. The PRO version handles a wider range of transponder chip types and supports more vehicle-specific IMMO procedures. For a shop that handles key programming regularly across multiple makes, the PRO version's broader coverage justifies the price difference over the standard model.

Compatible Tablets

The XP400PRO is designed to work with Autel's MaxiIM and MaxiSYS tablet platforms that include key programming software. Confirm compatibility with your specific tablet model — not all MaxiSYS tablets include the IMMO software suite required to use the XP400PRO. Call us to verify your tablet's compatibility before purchasing this accessory.

Who Should Buy This

• General repair shops that handle lost key and key programming jobs in-house rather than subbing them out to a dealer or locksmith
• Locksmiths adding automotive IMMO programming capability to their service offering
• Shops already running Autel MaxiIM or MaxiSYS who want to add or upgrade key programming capability without buying a separate dedicated key programmer

Practical Buying Notes
