Compare Hyundai I20 immobiliser fault repair quotes from specialist garages

The i20 is a practical, efficient and stylish small car, making it a popular choice for urban commuters. There is a more exciting side to this model, too, because it is used as the basis for Hyundai's rally car, competing in the World Rally Championships (WRC).

At the 2023 WhatCar? Awards, the Hyundai i20 N was crowned 'Hot Hatch of the Year' - a highly sought-after title - earning praise for its "brilliant body control and grip". Two years before, it was also named 'Car of the Year' at Top Gear's annual awards. The most recent generation of the i20 is exceptionally reliable; in earlier models from 2009-15, watch for signs of clutch wear and blocked DPFs in diesel engines.

An immobiliser is a security device that prevents a vehicle from starting without the correct key fob. It usually disables two of the following: the fuel system, ignition or starter motor.

If you're having trouble unlocking or starting your car, you can't turn the car key, or the alarm is going off, you may need to call a car immobiliser specialist. However, check the battery in your key fob first, especially if you can't lock/unlock your car, as this is the most common cause of immobiliser issues.

Other potential causes include damaged wiring, faulty actuators or sensors, damaged receiver rings, and a faulty ECU, all of which require a car immobiliser fault repair.

Fortunately, car locksmiths usually offer mobile immobiliser repair, so you don't need to go to a garage, and they can add or remove keys from the immobiliser system if there is a problem with the coding.
