Definition
Capturing a garage door remote's radio signal and replaying it later to open the door. It only works against old fixed-code openers, which transmit the identical signal on every press — the reason every major manufacturer switched to rolling code in the mid-1990s, where the signal changes with each press and a captured code is useless. If your opener predates rolling code, no accessory patches this; replacement is the fix, and it brings modern safety hardware along.
