Cheap Mercedes-Benz EQS Ignition Barrel

No — the EQS is a fully electric vehicle and has never had a traditional ignition barrel on any variant. Instead of a key-turned barrel, the EQS uses a push-button start system operated via a smart key or keycard, so there is no physical ignition barrel to source. If you are having starting or key recognition issues, the part you are most likely looking for is the start/stop button module, the steering column electronic module, or possibly the key itself — confirm with a breaker exactly which component is causing your fault.

Because the EQS has no ignition barrel, what is commonly called the 'ignition switch' on a conventional car is replaced here by the push-button start unit and its associated steering column electronics. Depending on your fault, you may need the start button assembly, the electronic steering lock module, or the EZS (electronic ignition switch) control unit — these are the functional equivalents on this platform. Describe your exact fault to your breaker and quote your registration so they can identify the correct module from a matching donor car.

The EQS (V297) launched in 2022 and received a facelift for the 2025 model year, so a 2022 and a 2024 car both sit within the pre-facelift generation — however, there is no ignition barrel on any EQS. If you are looking for a related electronic module such as the EZS unit or push-button start assembly, pre-facelift parts may well interchange within that window, but you should confirm against your exact registration with the breaker before purchasing, as software and hardware revisions can occur mid-cycle.

Because the EQS has no ignition barrel on any variant, trim and drivetrain do not affect this particular search. If you are sourcing a related electronic module such as the start button or EZS unit, the drivetrain layout (rear-wheel drive 450+ versus four-wheel-drive 580 4MATIC) could potentially affect certain steering column components, so always quote your full registration to the breaker to ensure the donor vehicle matches your car.

Neither the EQS nor the EQE has an ignition barrel — both are fully electric Mercedes models built on the same EVA2 platform and both use push-button start systems. That said, if you are looking for a related electronic module, there may be some parts commonality between the EQE and EQS given the shared platform, but this is something you must confirm with your breaker against both registrations rather than assume interchangeability.
