How do I reprogram a garage door remote after changing the battery in Dubai?

Usually you replace the battery, then pair the remote again by pressing the learn button on the opener and pressing the remote button within the time shown in the manual. Many remotes keep their memory, so a fresh battery is all that is needed. If the remote still fails, test it at close range to rule out weak signal, and check whether the opener has lost its memory after a power cut. Rolling-code systems from brands such as Somfy, Nice, LiftMaster, Sommer and BFT each have their own pairing steps. If you cannot find the model, send us a photo of the label and we can advise on the next step.
