Keyless+Entry

toc The **Keyless Entry** system was introduced to the 300ZX in 1994. The Factory Service Manual refers to it as the 'Multi-Remote Control System'. The antenna is built into the hatch glass (upper-left) except on the convertible models, where it is in the windshield (lower-left). The remote control unit is located behind the radio. It featured a standard wireless remote key fob, with buttons for the following functions:
 * Lock Doors
 * Unlock Doors
 * Unlatch Hatch
 * Panic

An extract from the 1994 FSM which covers the keyless entry system can be found here:

=Programming= From the FSM:

ID Code Entry Procedure
To enter the ID code, follow this procedure.

Setting Mode
Three steps must be followed to establish the "setting mode".
 * 1) Open the trunk.
 * 2) Close and lock all doors.
 * 3) Insert and remove the key from the ignition more than six times within 10 seconds.
 * • At this time, the original ID codes are eliminated.**

ID Code Entry

 * 1) Unlock and lock the driver's door inside lock lever once.
 * 2) Push lock button on the new remote controller once (for example, if door is locked using the remote controller during this ID code entry enable state, a new ID code can be entered).
 * **At this time, the new ID code is entered.**
 * If you need to enter additional remote controllers (including the original) repeat the steps for ID code entry above for each additional controller.
 * This ID code entry enable state and setting mode remain until any one of the doors is opened.


 * Note**
 * **• If the same ID code that existing in the memory is input, the entry is canceled, and no ID code will be entered.**
 * **• Entry of maximum four ID codes is allowed and any attempt to enter more will be ignored.**
 * **• Any ID codes entered after termination of the "setting" mode will not be accepted. Additionally remote control signals will be inhibited when an ID code has not been entered during the "setting" mode.**
