Used door lock mechanisms vary between vehicles - and whether you call it used, second hand or a replacement, matching the right one matters. These are the details breakers need to match the right part to your car - our request form asks them so you only hear from suppliers with the correct part:
Yes, generation matters significantly: the first-generation CLA (C117) ran from 2013 to 2019, with a facelift in 2016, while the second-generation CLA (C118) launched in 2019. Mechanisms from a C117 will not be a straight swap onto a C118 as the door architecture changed between generations. Always confirm the generation of the donor part with the breaker against your registration before buying.
Yes, side is critical – the OS (offside, driver's right) and NS (nearside, passenger's left) mechanisms are not interchangeable as they are handed to suit the door frame. When contacting a breaker, always specify whether you need the OS or NS unit along with which door position (front or rear) it came from.
For the front doors the fitment should be the same between the saloon (C117/C118) and the Shooting Brake (X117/X118), but rear door mechanisms may differ due to the different body and door shapes. Confirm the exact body style and door position of the donor vehicle with the breaker to make sure you get the right unit.
Trim level does not affect door lock mechanism fitment – the mechanism itself is the same across SE, Sport, and AMG Line variants within the same generation and body style. You may find cosmetic differences on surrounding trim pieces, but the lock mechanism is purely functional and unaffected by trim designation.
The first-generation CLA (C117) received its facelift in 2016, so depending on the build date your car could be either the pre-facelift or the updated model. Whether that facelift boundary affects lock mechanism compatibility is something you should confirm with the breaker against your exact registration, as internal door hardware can change at a refresh even when the body looks similar.
No – engine and transmission choice have no bearing on door lock mechanism fitment whatsoever. What matters is the generation (C117 or C118), the body style, the door position (front or rear), and the side (NS or OS), so focus on those details when speaking to a breaker.
