Abstract
An ID code is wirelessly sent to a device, such as a keyless-entry system or a keyless-starter system mounted on an automobile, from a portable transmitter. Electronic components including an electronic circuit board, a transponder and a battery are all contained in a resin case. The resin case is composed of a front case and a rear case, both firmly connected to each other. The case cannot be opened to take away the transponder contained therein without breaking the case. If the case is forcibly opened, a trace showing such a fact is unavoidably left on the case. The battery contained in the case, however, can be replaced or unloaded without breaking the case through an opening formed exclusively for the battery.
