Vauxhall & Opel Astra K Steering Lock Replacement and Emulator Service

If your Vauxhall or Opel Astra K fails to start even though the key appears to work, the issue could be caused by a faulty Electronic Steering Lock (ESL or ELV). This is a common problem across many Astra K models, resulting in a locked steering column and a complete no-start condition.

At Mr. Ignition, we supply and program new steering lock units and emulators, offering a fast and reliable solution to restore your vehicle’s ignition and steering functionality.

Common Symptoms of a Faulty Steering Lock

• Engine does not start even though the dashboard powers up

• Steering wheel remains locked despite using the correct key

• “Steering fault” or “Immobiliser active” warning displayed

• Clicking noise from the steering column or no sound at all

• Vehicle intermittently fails to recognise the key

These symptoms are clear signs of an electronic steering column lock failure. Even with a valid and working key, the vehicle will not start until the steering lock is replaced or bypassed.

Compatible Models

This service covers the following vehicles:

• Vauxhall Astra K

• Opel Astra K

• Other compatible Opel/Vauxhall models using the same steering lock system

Compatible Part Numbers

We can supply and program steering lock units and emulators for systems with the following or equivalent part numbers:

If your vehicle’s steering lock matches one of these part numbers, our replacement or emulator service is fully compatible.

Common Fault Codes

A failed steering lock on Vauxhall and Opel models often triggers one or more of these diagnostic trouble codes (DTCs):

• B1026 – Steering Column Lock Fault
  The ECU cannot communicate with the steering lock module.

• B1027 – Steering Lock Control Module Malfunction
  The steering lock has failed to unlock or report its position.

• U3000 – Control Module Internal Error
  Indicates a hardware or circuit failure within the steering lock unit.

• B3055 – No Communication with Steering Lock ECU
  The body control module (BCM) has lost signal to the lock system.

These codes typically cause the ignition to remain inactive or the steering to stay locked, preventing the engine from starting.
