Push-Button Ignition Switch for Intelligent Key 🔑

This OE-grade start/stop button assembly restores reliable push-start operation on your Nissan sports coupe. It communicates with the immobilizer and body control module to power ACC, ON, and START modes, giving you factory feel and crisp response every time 🚗.

Why this part is needed

Worn contacts, tired microswitches, or a failing LED ring can cause delayed starts, multiple-press starts, or a dead button. Replacing the unit brings back secure ignition, smooth mode cycling, and proper key recognition—no more guesswork at the button ✅.

How it works

With the fob in range, low‑frequency antennas wake the transponder; the fob replies via RF. After validation, pressing the switch sends a LIN/CAN request to the BCM/ECM. Brake/clutch inputs are checked, the starter relay energizes, and the ring LED shows status. Internally, a sealed tactile switch and PCB manage clean signals for long life ⚙️.

What happens if it’s broken

Symptoms include no crank with key recognized, stuck in ACC/ON, random beeps, KEY warning light, intermittent starts, or a drain from a stuck LED. DTCs like B26xx may appear. Replace the unit to restore normal operation; coding is usually not required.

Install & fitment notes

Direct plug‑and‑play. Disconnect the battery, pop the bezel, swap the module, and seat the connector fully. Test with both fobs.
