IKey & Chip Buying Guide: How to Pick the Perfect One for Your Vehicle
Choosing the right key or chip for your vehicle can be confusing, especially with so many options on the market. Some car owners need a fully functional smart key, while others are looking for a chip that can be installed directly on an existing key. In this guide, we’ll help you understand whether an iKey or an AT100 chip is suitable for your car model, so you can make an informed decision and avoid costly mistakes. By the end, you’ll know exactly what type of key or chip fits your vehicle’s system and your needs.
How to Choose the Right iKey for Your Vehicle
Autel universal keys primarily refer to the Autel IKEY series. As universal programmable smart keys, the Autel IKEY can be programmed to replace the smart keys for over 700 vehicles, including those from BMW, Hyundai, Nissan, Chrysler, Ford, Honda, and General Motors. The Autel iKey is a versatile, multi-brand programmable key designed for locksmiths and multi-brand automotive technicians. It supports a wide range of chip types and remote frequencies, and can be generated and programmed using Autel tools such as the KM100. With a relatively low price, typically between $10 and $40, the iKey is ideal for key duplication, replacing lost keys, or serving as a universal replacement solution.
Before Choosing the Right iKey, Confirm the Following:
-
Car Model and VIN
Verify the exact vehicle model, year, and VIN to ensure compatibility. -
Transponder Chip Type
Identify the chip type using KM100 or other supported diagnostic tools. -
Original Factory Key Information
Check the FCC ID or OEM information printed inside the original key shell. -
Remote Frequency
Confirm the correct key frequency required for your vehicle.
Next, open the iKey file and use the search function to match the vehicle’s brand and model year. Carefully compare the FCC ID listed in the file and confirm that the key frequency matches the vehicle’s requirements. Once all the information is aligned, select the iKey version that is fully compatible with the vehicle.

Ensure you know the exact vehicle details to match the AT100 chip correctly. -
Key Frequency
Confirm the required frequency for your mechanical key to ensure compatibility.
Verifying these details first, ensure that the mechanical key’s frequency matches the AT100 chip’s supported frequency for proper operation. It will help prevent compatibility issues and ensure a successful key replacement or duplication.
Next, open the AT100 compatibility file and use the search function to locate your vehicle’s make, model year, and key frequency to determine whether the AT100 chip is suitable.
