ABSTRACT:
A keyless access control system (10) controls access through an entranceway (e.g., a door 16) into a vehicle (12). A sealed security input module (14) of the system (10) is mounted on the vehicle (12) at a location to be accessible by an operator (18) located outside of the vehicle (12). The module (14) includes a keypad (22) manually actuatable by the operator (18) to enter a security code. The module (14) also includes a code-transmitting transmitter (26 and 28). A code-receiving receiver (38 and 40) is located in the vehicle. An induction power coupling (50) connects the security input module (14) and a vehicle power system (58). Preferably, a first half (48) of the induction coupling (50) is located in the module (14), and a second half (52) of the induction coupling is adjacent to the first half (48). During operation, power from the vehicle power system (58) is transferred to the module (14) via the induction coupling (50). The operator (18) manually inputs the security code to the module (14). The code-transmitting transmitter (26 and 28) of the module (14) transmits a RF signal (30) conveying the security code. The code-receiving receiver (38 and 40) receives the signal (30).
