Made in Germany for MARANTEC. At Marantec, security is at the forefront of all our developments. This is why our remote technology works with encryption, which is the same as is used in online banking. In addition, it also uses a rolling code algorithm, which means that it transmits a different code to the opener every time the opening button is pressed, which makes it near impossible for the code to be copied or decoded. This technology is known only to our engineers, and we produce all of our remote products ourselves in our own factories. This all adds up to one of the most secure and comfortable door openers in the world.
