The Keydiy ZB66 smart remote is a 3-button universal smart key designed as a direct replacement for original Peugeot, Citroën, and DS keys. Its primary selling point is its identical design and build quality to factory keys. The key feels robust, the buttons provide the same tactile feedback and audible click, and it is built to withstand daily use.
This makes it an ideal solution for:
- Total key replacement for lost keys.
- Creating duplicate keys.
- Replacing damaged or broken customer keys.

ZB66 Main features:

- Compatibility with Peugeot / Citroën / DS / Opel / Toyota
- Supported technologies: ID46, ID49, ID4A, IM2A, IM3A
- Unlimited key reprogramming
- Solution designed for automotive key professionals
The most significant innovation of the ZB66 is its extreme flexibility. Traditionally, professionals needed to stock multiple key references (blanks) to cover different vehicle protocols. The ZB66 consolidates this into a single, programmable reference.
How does it work? The key is purchased “blank.” Using KEYDIY tools like the KDX2, KD-X4, or KD-Max, a specific file is generated and loaded onto the key. This process allows the ZB66 to be configured into various transponder types, including:
ID46 (Proximity / Hands-free)
ID4A / ID49
PCF / PC (iM2A type)
NCF (iM3A type)
This means one key blank can be transformed to suit a wide range of vehicles, such as a 2022 Peugeot 308 or a 2018 Peugeot 208, drastically simplifying inventory management.
A major cost-saving feature is the key’s unlimited reprogrammability. Unlike some OEM-style keys that are “locked” to a vehicle once programmed, the ZB66 can be reprogrammed without penalty.
If a programming attempt fails, the key is not wasted.
If a key was previously programmed to one vehicle, it can be erased and reprogrammed to another.
This eliminates the risk of losing money on faulty programming attempts and enhances the key’s long-term value.
While generation requires a KEYDIY device, the programming phase is not locked into the KEYDIY ecosystem. Once the key is generated with the correct file, it can be programmed to the vehicle using popular industry tools like the Autel MaxiIM IM508/608, Xtool, OBDSTAR G3, Zed Full etc. This is a crucial advantage for workshops already invested in other diagnostic and programming equipment. Once the key is generated, programming is not limited to the KEYDIY ecosystem. The ZB66 therefore integrates seamlessly into a workshop already equipped with OBDSTAR or ZED tools.
Simple Preparation Process
Preparing the key is straightforward:
- Remove the emergency blade by pressing the side button.
- Use a flat tool to gently pry open the case to access the battery compartment.
- Insert a standard CR2032 battery.
- Close the case and reinsert the blade.



The key is then ready for file generation, a process shown to take less than two minutes using the KEYDIY software.
Conclusion: The Ideal Solution for Professionals
The KEYDIY ZB66 presents itself as a super-polyvalent, cost-effective solution tailored for automotive professionals—from independent locksmiths and garages to multi-service centers and diagnostic specialists. By reducing inventory needs, eliminating the risk of wasted keys, and maintaining compatibility with popular programming tools, it streamlines operations and improves profitability.
This key represents a shift towards smarter, more adaptable tools in the automotive aftermarket, proving that sometimes, having one master key is better than stocking five.
