Common faults
- Steering will not unlock and the dash stays dead

- Audible click or whirr from the column, then nothing
- Intermittent no-start that worsens over weeks, often in cold weather
- Worn DC motor and stripped plastic worm gear inside the unit
Repairable?
// Bench verdict
Yes — this is the most common reason a W204-era Mercedes goes completely dead with the key in, and it is repairable: motor, gears and board renewed, then re-synchronised with the EZS and proven through repeated lock/unlock cycles under load. An emulator is fitted only where the original lock is genuinely beyond saving.
