433MHz Universal Garage Door Remote Cloner - Copy Remote Controller For Gates, Shutters, Alarms (ABCD Buttons)

Lost a remote? Need a spare for your garage door, gate, or roller shutter? This little red gadget can clone most standard 433MHz fixed-code remotes. It's a 'learning' remote with four buttons (A, B, C, D), so you can copy up to four different original remotes onto it. The process is usually simple: hold the original and this remote together, press a button, and it copies the signal. It has a good range (50-100m) and runs on a common 12V battery (not included). Handy for creating backups without needing to buy expensive proprietary replacements. Just note, it generally won't work with newer rolling-code security systems.
