Key benefits Quickly duplicate common fixed and learningcode remotes so you can a lost fob or add extra remotes for family and staff. Precise control: four independent buttons (4button key fob), each programmable to a single original remote button. compatibility for 433.92 MHz systems: designed to clone 99.99% of common fixed and learning code remote controls used for cars, gates, alarms, and home automation. Main features Frequency: 433.92 MHz fixedfrequency remote cloner. Buttons: Four separate buttons — program each button independently to control individual devices. Indicator: LED status indicator to guide clearing and learning operations. Performance: Supports cloning of both fixedcode and many learningcode remotes when the original meets the listed requirements. Compatibility and requirements This product is not a universal remote. To successfully clone an original remote you must meet all of the following: 1) The original remote must operate normally (able to transmit). 2) You must know and match the original remote's transmitter frequency (this cloner works at 433.92 MHz). 3) The coding chip/type used by the original remote must be identifiable and supported (see list below). 4) For remotes without marking on the chip, check the list of supported foreign nonstandard codes/brands and images to confirm compatibility. Common coding chips that can be copied 2260, 2262, PT2264, SMC5326, SC5262, HT12E, HT12D, HT600, HT680, HT6207, HT6010, HT6012, HT6014, SMC918, SM5028S, 527 series, 1527, 2240, and various foreign nonstandard codes (see product materials for detailed brand lists and images). How to copy (twostep process) Step 1 — Clear existing code on the remote: Press and hold the A and B buttons simultaneously. The indicator LED will blink briefly and then go out. Only after the LED goes out is the remote cleared and ready for learning. Step 2 — Learn from the original remote: After clearing, press the remote button you want to program once, then press the corresponding button on the original remote three times while the LED is blinking. The LED will indicate learning status; when it behaves as described in the instructions, the copy is complete. Notes and troubleshooting If the LED remains on continuously (transmitting state) instead of blinking during the clear step, release and repeat the simultaneous A+B press until the LED blinks and then goes out. Follow the twostep process exactly for reliable results. If the original remote's chip is not clear or the frequency differs from 433.92 MHz, cloning may not be possible. Practical use scenarios a lost garagedoor fob: clone an existing working garage remote so you have a spare for family members. Add a remote for shared use: program a second remote for a car alarm or home alarm system to give to a family member or valet. Integrate into home automation: duplicate remote control signals for shortrange wireless lamps or motorized skylights so multiple remotes control the same device. Technical summary Function: 433.92 MHz fixedfrequency remote cloner for copying fixed and learningcode remotes. Buttons: 4 programmable buttons (one function per button). Supported chips: See list above for commonly supported coding chips and foreign nonstandard codes. Success rate: Designed to copy 99.99% of common fixed and learning code remotes when compatibility conditions are met. Keep the original remote available and follow the clearandlearn steps for results.
