Common Technology in Many DEI Aftermarket Alarm System Remotes

Many of DEI’s aftermarket alarm system remote transmitters used the same basic electronic technology. Consequently, many different parts are interchangeable. For example, DEI remotes with an FCC ID beginning with EZSDEI474, EZSDEI475, EZSDEI476, EZSDEI7141 and EZSOEMTX all can be replaced by a single 4-button remote, part A-474K.
