Key-in-ignition lock reminder system

摘要

A key-in-ignition lock reminder system uses a key (20) having a transponder (22) with an identification code. An ignition lock (18) for receiving the key has an adjacent antenna (16). A door proximity switch (34) connected to the door generates a door open signal when the door is open. A control module (10) is connected to a door lock control (40), the door proximity switch (34) and a memory (12) storing at least one identification code. The control module (10) energises the antenna coil which energises the transponder (22). The transponder (22) then transmits an identification code which is received by the antenna (16). The control module (10) generates a control signal if the code from the transponder (22) is equivalent to an identification code stored in the memory (12) and the door proximity switch (34) indicates the door is open. An indicator (38) connected to the control module receives the control signal and generates an indication that the key is in the ignition lock.
