Merlin Garage Door remote programming

Here at Finakeys locksmiths Belfast, we sometimes get asked about Garage door remote controls. Below is a video of a Merlin Garage door remote being programmed into the system.

Remember the Merlin remote uses a rolling code frequency so cloning the remote is unlikely to work. If you do buy an aftermarket remote, please ensure it is a rolling code as fixed code remotes will not operate with the Merlin system.
