HINT:
If the new key ID code registration fails, code 2-1 will be output through the security light. Trying to re-register an already registered door control transmitter assembly will cause code 2-2 to be output when the door control transmitter assembly is inserted. If the number of registered key ID codes exceeds the maximum limit, code 2-3 will be output through the security indicator light (combination meter assembly). The output details are shown in the following illustration.
