An ESL (Electronic Steering Lock) or ESCL (Electronic Steering Column Lock) fault occurs when the steering lock module fails to unlock or communicate with the vehicle’s immobiliser system. This prevents the car from starting and often leaves the steering wheel in an immobile position.

Common symptoms include a locked steering wheel, no ignition lights, the key not being recognised, warning messages such as “Steering Lock Malfunction”, or the vehicle being completely unresponsive.

In many cases, the ESL can be repaired or refurbished rather than replaced. Where repair is not possible, we can replace the unit or fit a programmed ESL emulator, depending on the vehicle and fault type.

An ESL emulator is a specialist electronic module that replaces the faulty steering lock function. It allows the vehicle to start and operate normally without the physical steering lock, while remaining synchronised with the immobiliser system.

Yes. Our service is fully mobile. We can diagnose, repair, program or fit an ESL emulator at your home, workplace or roadside, without the need for recovery to a garage or dealership.

An ESL fault itself is not directly an MOT test item, but if the vehicle cannot start, steer correctly or displays immobiliser-related warning messages, it may be considered unroadworthy.

Most ESL repairs or emulator installations are completed within 1 to 2 hours, depending on the vehicle model and fault complexity.

In most cases, yes. The original key is required to correctly synchronise the ESL, EIS / EZS and immobiliser system. If keys are lost or faulty, we can advise on replacement and reprogramming options.
