Compare Fiat Grande Punto immobiliser fault repair quotes from specialist garages

Fiat is known for its small-sized vehicles, like the iconic Fiat 500 and the Fiat Panda, famously one of ex-Top Gear presenter James May's favourite cars. Take a look at our list of top ten cars like the Fiat 500 here.

However, the brand has also branched out from its small-car origins, and in 2023, a Fiat E-Scudo all-electric van set a world record for the longest distance travelled by a van on a single charge, covering just over 311 miles.

Despite the earliest Fiat 500 being released all the way back in 1957, the latest iterations are still making waves, winning 'Best Small Car' at the 2022 Autocar Awards, with its electric counterpart, the 500e, winning 'Best Electric Small Car' at the 2023 WhatCar? Electric Car Awards.

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.
