A security alarm device is replicated in a toy vehicle. The security device includes a remote control which also can control vehicle functions. The remote control may control alarm arm and disarm, alarm and vehicle sounds such as arm, disarm, alarm set off, engine revving, tire screeching, motor drive, and vehicle lights. The security alarm device includes an LED which indicates whether the alarm is armed or unarmed, and a motion sensor which sets the alarm off (e.g., emitting a siren sound) when the toy vehicle is moved in its armed state.
