Hello I have done the procedure on the small sheet included with the K8059 kit but there is no way to change the unique code of this kit. Is someone could help me please. The kit is associated with k8057 Kit.
thank you
Most likely you did not follow the order correctly
OR
You have soldered one or two coding jumpers at the solderside, right below the IC.
There should not be any jumpers closed if you intend to use the unit with the K8057 receiver.
ALSO:
Make sure that the K8057 receiver is completely erased before attempting to learn a new code, otherwise it is possible that it still responds to the default code (see manual for how-to instructions).
