A memory (,) of a transmitter (,) of a transceiver (,) for a vehicle has four writing error check areas in which &ldquo;Low&rdquo; is written at the beginning of a writing process and &ldquo;Hi&rdquo; is written at the end of the writing process. As a result, when the writing error check area is read in a data reading process, it is possible to confirm whether writing has been finished correctly. Further, there are provided four rolling code data storing areas in the memory (,). The area which is written into is changed each time a rolling code is incremented. When transmission data is read, if data within a writing error check area is &ldquo;Low&rdquo;, data is read from the previous rolling code area, and on the basis of the read data, transmission data is generated.
