This is a common problem on the Renault megane car , and a problem that is more often than not incorrectly diagnosed by national roadside recovery firms .
Roadside recovery firms often diagnose this as a faulty key card as it wont turn over and start , This is incorrect , this normally points to 1 of 2 common faults ;
1) Steering lock fault ( a new steering lock unit is required )
2) Body control Module ( a new BCM Unit is needed )
This is never a fault with your key card .
when the key card is at fault , the dash on the vehicle will say card not detected when inserted .
