A mechanical key and lock cylinder with mechanical bittings include an electronic access control feature, with minimal modification and without affecting or interfering with the mechanical function of the key and cylinder. A small, low-profile memory cell is embedded in a recess or later hole through the key, with one cell terminal grounded to the key and the other having a contact extension. When the key is inserted into the keyway of the cylinder plug, the ground connection is made with the cylinder and the memory cell contact extension engages a spring-loaded contact of a connector unit which extends from the cylinder plug. An insulated wire carries the conductive path out of the lock cylinder. The key remains of very low profile, and the cylinder plug is modified only by a small longitudinal bore from front to rear. Existing mechanical locks and cylinders can easily be retrofitted with the electronic access control feature. In another embodiment the key has its contacts on one or both sides of the key blade rather than at the shoulder of the key head. The memory cell device in or on the key head can include a microprocessor, battery and read/write memory.

We claim: 1. An electronic key comprising: a housing; a key blank having a portion for insertion into a keyway of an electronic lock assembly, the key blank being attachable to the housing; a memory cell positioned within the housing for supplying data relating to the electronic lock assembly intended to be operated by the electronic key; and a data pin positioned to extend through an aperture formed in the housing and being electrically connected to the memory cell for transmitting data supplied thereby, wherein the key blank has an opening to accommodate the memory cell in association therewith. 2. The electronic key according to claim 1, wherein the housing has a front surface from which the-data pin protrudes in its extended position, for touching and operating an electronic lock as the key is moved toward the lock with the front surface facing the electronic lock, and the data pin is movable between its extended position to a position flush with the front surface of the housing upon insertion into the electronic lock. 3. The electronic key according to claim 1, wherein the data pin includes a stop portion to limit the outward extent of its movement relative to the housing. 4. The electronic key according to claim 1, wherein the data pin is biased by a spring member toward an outwardly extended position, and wherein the spring member limits the inward movement of the data pin with respect to the housing. 5. The electronic key according to claim 1, wherein the data pin is biased by a spring member toward an outwardly extended position, and further comprising a data contact member in electrical connection with the memory cell when mounted in conjunction with the housing, with the spring member being formed in association with the data contact member and electrically connecting the data pin to the memory cell. 6. The electronic key according to claim 1, wherein the data pin is biased by a spring member toward an outwardly extended position, and wherein the spring member is engaged to the data pin, and limits the extent of travel of the data pin from its extended position. 7. The electronic key according to claim 1, wherein the key blank includes an outwardly extending portion adapted to operate a standard lock mechanism. 8. The electronic key according to claim 7, further comprising a data contact member positioned within the housing and having a portion thereof contacting the memory cell, the data contact being an electrical connection with the data pin for transmitting data through the data pin. 9. The electronic key according to claim 1, wherein the data pin is biased by a spring member toward an outwardly extended position, and wherein the spring member electrically connects the data pin to the memory cell throughout movement of the data pin from a fully extended position to a fully retracted position. 10. The electronic key according to claim 1, wherein the data pin is biased by a spring member toward an outwardly extended position, and further comprising a data contact to electrically couple data from the memory cell through the spring member and data pin, the data contact having a contact portion which is spring loaded to maintain contact with the memory cell upon assembly in the housing. 11. The electronic key according to claim 1, wherein the housing includes first and second portions which are assembled together to enclose a portion of the key blank and a portion of the data pin therein. 12. The electronic key according to claim 11, wherein the first and second portions of the housing include structures to position the key blank, memory cell and data pin in proper positions when assembled together. 13. The electronic key according to claim 1, wherein the housing includes a reinforcing member having an aperture formed there through into which the data pin is sizably positioned, to engage the data pin over a portion of its length and facilitate proper movement of the data pin relative to the housing. 14. An electronic key comprising: a housing; a key blank having a portion for insertion into a keyway of an electronic lock assembly, the key blank being attachable to the housing; a memory cell positioned within the housing for supplying data relating to the electronic lock assembly intended to be operated by the electronic key; and a data pin positioned to extend through an aperture formed in the housing and being electrically connected to the memory cell for transmitting data supplied thereby, wherein the memory cell is biased into electrical connection with a data contact member which in turn is electrically connected to the data pin. 15. The electronic key according to claim 14, wherein a spring member is positioned within the housing to bias the memory cell. 16. An electronic key comprising: a housing; a key blank having a portion for insertion into a keyway of an electronic lock assembly, the key blank being attachable to the housing; a memory cell positioned within the housing for supplying data relating to the electronic lock assembly intended to be operated by the electronic key; and a data pin positioned to extend through an aperture formed in the housing and being electrically connected to the memory cell for transmitting data supplied thereby, wherein the key blank has an opening for mounting the memory cell therein by interference fit. 17. An electronic key comprising: a housing; a key blank having a portion for insertion into a keyway of an electronic lock assembly, the key blank being attachable to the housing; a memory cell positioned within the housing for supplying data relating to the electronic lock assembly intended to be operated by the electronic key; a data pin positioned to extend through an aperture formed in the housing and being electrically connected to the memory cell for transmitting data supplied thereby; and a spring member positioned in the housing to bias the data pin to an outwardly extended position, wherein the biasing of the data pin to an outwardly extended position maintains contact of the data pin with a data contact pin associated with the electronic lock assembly from its fully extended position to a fully retracted position.
