This remote has been discontinued, and it is replaced by DOM505 which is made by Dominator in the same format and does the same job. However we would recommend you to purchase a new conversion kit MK701 (with one remote) or MK702 ( two remotes) as this new conversion kit (also a more valuable option) will allow you to program up to 30 remotes just in case your current receiver is out of memory capacity. You only need to hook three wires of the receiver which will work straight away. We will program everything before dispatch. Your existing DOM501 will still work.
This one has been upgraded to DOM505.
