Q I have a keyless 2009 Ford Fiesta. My fob allows me to open the doors, but sometimes when my foot is on the clutch to start the car, it says: ‘Key not detected’. I have to get out of the car, lock and unlock the doors, and try again before it will start. I’m worried that one day it might not start. Mick Peters
A The message ‘key not detected’ is usually displayed when the key-fob code is not recognised. In such cases, the fob will need to be reprogrammed. However, as yours only intermittently displays this message, I suspect that the problem is simply a low battery. Hopefully, replacing the CR2032 battery will fix the problem. Whatever the case, there is an emergency start procedure for the vehicle if the passive key is not recognised. This is to use the transceiver, which is placed in the steering lock. By pressing the passive key gently against the steering column in the position where the ignition lock would be on a regular Fiesta (this will be a blank flat panel), then operating the clutch and start button, the system will recognise the key and allow the vehicle to start.
