KEYDIY KD900+ Bluetooth Remote Maker for iOS and Android

The KEYDIY KD900+ is a smartphone-based device designed to create and manage vehicle remotes. This product holds a national patent and was developed through the collaborative efforts of international and domestic engineering teams. Locksmiths can use a single blank remote to produce over 500 different car remote types, thanks to a real-time database that updates daily. This significantly reduces inventory requirements. The KD900+ is widely used in garages and key shops and has become an essential tool for professional locksmiths.

Key Features

• Creates Over 200 Types of Remotes—Using KEYDIY remote blanks, the KD900+ can generate fully functional remotes and remote head keys for customers. Compatible with Audi, BMW, Chrysler, Ford, GM, Honda, Hyundai, Kia, Mazda, Nissan, Subaru, Toyota, VW, and many others. It can also adjust remote frequencies as needed. Each generated code is unique and never repeated, ensuring security and allowing multiple remotes to be programmed for the same vehicle.
• Remote Frequency Testing—Test remote functionality and identify operating frequencies between 312 MHz and 868 MHz. Unlike most testers, it distinguishes between ASK (amplitude shift keying) and FSK (frequency shift keying) modulation modes.
• Copies Alarm Remotes or Garage Door Openers—With F-Series remote head keys, one remote can control both a vehicle and a garage door. It copies all fixed-code garage transmitters (300–500 MHz) and most anti-theft and rolling-code garage transmitters.
• Use Your Smartphone as Your Car Remote—COMING SOON! Use your Bluetooth-enabled smartphone to lock, unlock, activate panic mode, or open the trunk. Includes a proximity feature that automatically locks or unlocks the vehicle when entering or exiting Bluetooth range. Requires the separately sold KEYDIY Entry module (coming soon).
• Smart Matching Technology—Operate the customer’s original remote while the KD900+ detects the correct vehicle data, simplifying your workflow. While still under development, this feature is already usable on many vehicle models.
• Remote Simulation—Test remote functionality using the KD900+ before generating the actual remote.
• Reprogram & Reuse Remotes—Remotes generated for one vehicle can be reprogrammed for another without issue.
• Easy Online Updates—The manufacturer continuously adds support for new vehicles and improves functionality. Firmware, software, and transmitter data can be updated automatically via user-friendly desktop software.
