Keyless Entry Module - 1991 300ZX Z32

The Z32 Nissan 300ZX utilizes a dedicated keyless entry control module typically located behind the glove compartment or integrated within the center console stack. For 1991 model years, the primary OEM reference is 28595-30P00, superseded by 28595-30P01, while 1992-1996 production transitioned to 28595-40P00 with revised mounting provisions and updated firmware. When sourcing from salvage yards, verify the three-pin antenna connector and main harness plug for green corrosion, as these modules commonly suffer from electrolytic capacitor leakage that damages the circuit board traces. Installation requires reprogramming remotes via the ignition-accessory sequence within specific time windows; early 1990-1991 modules utilize different communication protocols than later units and are not plug-and-play interchangeable. Twin-turbo VG30DETT and naturally aspirated VG30DE models share identical modules, though JDM variants may operate on incompatible frequencies. Always test signal reception range before final installation, as the integrated antenna amplifier frequently fails independently of the logic board, mimicking module failure.
