Abstract
A remote keyless entry vehicle receiver includes a memory that stores a security code for uniquely identifying a transmitter that is authorized entry into the vehicle. The memory also stores a broadcast code that identifies a broadcast message intended for general use by a group of vehicles, each being equipped with a similar receiver. A signal is received which includes at least a coded portion. The received coded portion is compared with each of the codes that are stored in memory. Vehicle entry is permitted when the received signal includes a coded portion that matches the stored security code. The driver is alerted and/or provided with a message when the received signal includes a coded portion that matches the stored broadcast code.
