Renault car keys, coding & electronics

About Renault

Renault gave us the Clio, the Megane and the hot-hatch-loving RS badge, plus the Zoe and the brilliant new electric 5. They also gave us the key card, a lovely idea that has caused more 'card not detected' moments than any other key on the planet, and the odd steering lock with stage fright.

AutoECU sorts Renault key cards and keys, steering lock and UCH faults, ECU repairs, coding and diagnostics on cars and Kangoo, Trafic and Master vans.
