Volkswagen Jetta Door Lock Mechanism Replacement Parts

The Mk5 Jetta ran from 2005 to 2010 and the Mk6 from 2011 to 2018, and these are distinct generations with different door structures, so mechanisms from one generation will not reliably cross to the other. Stick to sourcing from the same generation as your car, and always confirm with the breaker using your registration to be certain.

Yes, generation matters significantly — a Mk5 (2005–2010) mechanism is not the same as a Mk6 (2011–2018) unit, so you need to match the generation of the donor car to yours. Within the same generation there can also be mid-cycle updates, so confirm with the breaker against your registration before buying.

Trim level does not affect the door lock mechanism itself — the fitment is determined by the generation and which door the part came from, not the spec level. You may find cosmetic differences in surrounding trim pieces, but the lock mechanism is interchangeable across trims within the same generation and door position.

You'll need to tell them the generation or year of your Jetta, and crucially which door the mechanism is from — NS (nearside, passenger side) or OS (offside, driver side), and whether it's a front or rear door. Providing your registration number is the safest way to ensure the breaker can match the correct part to your vehicle.

No — front and rear door lock mechanisms are different parts and are not interchangeable, as the door geometry and latch positions differ. Always specify front or rear, as well as NS or OS, when requesting a quote from a breaker.

This spans the Mk5-to-Mk6 generation boundary (Mk5 ended 2010, Mk6 began 2011), and parts across that boundary are very unlikely to be compatible due to the change in door design. We'd strongly recommend confirming with the breaker against both registrations before purchasing, rather than assuming they will interchange.
