Secondary security and authentication for trainable transceiver

A transmitter device for activating a remote system, comprising:

• a processing circuit;
• a transmitter coupled to the processing circuit;
• a battery powering the processing circuit and the transmitter;
• and
• a plurality of buttons coupled to the processing circuit;
• wherein the processing circuit is configured to allow a transmission from the transmitter to the remote system in response to a determination that a user has entered a correct multi-button code at the plurality of buttons.

A trainable transceiver unit for mounting in a vehicle, the trainable transceiver unit comprising:

• a transmitter configured to transmit a remote control signal for controlling operation of a remote electronic system;
• a user input interface configured to receive a request for transmission of the remote control signal;
• a security module configured to receive a security input signal, compare the security input signal to a stored valid security code, and transmit a security control signal to a processing circuit based on the comparison;
• and
• the processing circuit configured to prevent operation of the transmitter unless the security control signal indicates operation of the transmitter is authorized.
