Used BMW i4 Door Lock Mechanism

Yes, the BMW i4 is a fully electric four-door gran coupé and has conventional door lock mechanisms on all four doors, just like any other car — the electric drivetrain makes no difference to the door hardware. You'll need to specify which door you need the mechanism for when contacting a breaker.

The BMW i4 launched in late 2021 and is currently in its first generation, so a 2022, 2023, or 2024 i4 are all the same generation with no confirmed mid-cycle structural door changes. That said, whether a specific used mechanism interchanges across those years is worth confirming with the breaker against your registration, as minor running changes can occur without public announcement.

Trim level does not affect the door lock mechanism — the fitment is determined by the door position and side, not whether the car is an eDrive35, eDrive40, or M50. You may find minor cosmetic differences in surrounding trim pieces, but the lock mechanism itself is the same across trims, so don't rule out a part purely on that basis.

Yes, side is critical — the nearside (NS, passenger/left) and offside (OS, driver/right) mechanisms are mirror images of each other and are not interchangeable. Always tell the breaker which side you need, and double-check this against your own car before ordering.

Yes, front and rear door lock mechanisms are different parts and will not interchange, so you must specify whether you need a front or rear unit as well as the side (NS or OS). The BMW i4 is a four-door body in all variants, so breakers should be familiar with all four door positions.

Because the i4 is a single generation so far (launched late 2021), year-to-year variation within that generation is low, but you should still ask the breaker to check the part against your vehicle's registration to rule out any running changes. Confirming the door position (front or rear, NS or OS) is the more important step to get right before purchasing.
