Autel APB112 Smart Key Emulator

Autel APB112 Smart Key Emulator

The APB112 is a professional smart key emulator accessory for Autel's MaxiIM key programming platform. Its primary function is to collect data from the ignition coil, diagnose ignition coil problems, and decode the data stored in a vehicle's key chip — and then emulate that chip signal. In plain terms: when you need to program a new key and the original key is not physically present (All Keys Lost scenarios), the APB112 simulates the key transponder signal so the programming process can proceed. It is not a standalone tool — it must be used with the XP400 key programmer and a MaxiIM tablet.

Required Equipment

The APB112 requires all three of the following to function:

• Autel MaxiIM tablet (IM508, IM508S, IM608, IM608 Pro, or IM608 Pro II series)
• Autel XP400 or XP400 Pro key programmer
• APB112 Smart Key Emulator (this unit)

This is an accessory, not a complete system. If you do not already own an Autel MaxiIM tablet and XP400, you will need those as well. The APB112 adds capability to an existing MaxiIM setup.

What the APB112 Does

Data Collection and Ignition Coil Diagnostics

• Collects data transmitted from the vehicle's ignition coil
• Identifies ignition coil faults and communication problems
• Decodes vehicle key chip data for analysis and programming

Chip Emulation

• Supports 46 chip emulation — one of the most common transponder chip types found in domestic and import vehicles
• Supports Toyota 4D smart key emulation — covers chip types 94/D4 and 98
• Supports Toyota H smart key emulation — covers chip types 88/A8, A9, and 30

Smart Key Password Calculation

• Supports 46 Smart Key Password Calculation — calculates the key password needed for programming certain 46-chip vehicles

Data Collection

• Supports 46 and 4D data collection — captures transponder chip data for cloning and programming workflows

Practical Use Cases

The APB112 is primarily used by professional locksmiths and automotive security technicians in these scenarios:

• All Keys Lost (AKL) programming — when no working key exists, the APB112 emulates the key signal so the vehicle can enter programming mode
• Add Key procedures — when adding a spare key and the emulator is needed during the process
• Ignition coil diagnostics — when a vehicle is not reading a known-good key, the APB112 helps determine if the coil itself is the problem
• Key chip decoding — reading and capturing chip data from an existing key before programming a replacement

Important Notes for Buyers

• Autel IMMO and key programming products are intended for use by licensed locksmiths and NASTF-certified Vehicle Security Professionals
• The APB112 must be combined with an XP400/XP400 Pro and a MaxiIM tablet — it does not work standalone
• Compatible tablets include the IM508 series and IM608 series
• Covered by a 1-year limited warranty

If you are building out an Autel IMMO capability, the APB112 works alongside other MaxiIM accessories:

• Key Programming Adapter Kit ($345) — 12 IMMO adapters for BMW/Mini/Rolls-Royce and VW/Audi/Mercedes-Benz
• APB131 Adapter ($50) — adds VW MQB and Nissan RH850 dashboard key reading
