Professional Mechanic Tips

Field notes from Marcus Vale, ASE-Certified Master Technician
Always keep a working spare key — it instantly tells you whether the problem is the key or the car's immobiliser.
On a Abarth 595 that will not start with a flashing key light, holding the fob directly against the start button often lets the immobiliser read a weak transponder.
