Driving with key out of Range

Post by Dar123 »

So I’ve been reading that the vehicles can be driven without the key being present in the vehicle. However my DS5 as soon as the key is out of range the car cuts out and you can’t move?


Does anyone know how far a vehicle can move without the key present as for me it’s only a few metres?

I don't know about the DS but my Renault Zoe automatically locks when the key's in my pocket and I walk away. If I get out of the car without switching it off the bleeper yells at me. :)

For the Hands Free Access part, the areas of detection are:

Definitions of a transmission zone "A":
Length: 3 metres
Width: 1,60 metres
Height: 1,60 metres

Definitions of a transmission zone "B":
Transmission beam: 1,60 metres
Height: 1,60 metres

For the Hands Free Starting, the fob must be in the detection zones shown below:

If the hands-free identifier is not detected by the cabin low frequency aerials, a message displays on the instrument panel matrix screen indicating the procedure to be followed for forcing the stopping of the engine.

In this case, a press of 3 seconds is required.

I can't see anything mentioned about automatically stopping the engine if the fob is missing. The reason I can see are safety concerns - if for example a passenger threw the fob out the window - you would not expect the engine to cut out on the motorway....

I read recently of a bloke started his bike in his garage, rode about twenty miles, stopped to fill up and couldn't start again. His fob was still in his garage.

It would have to be exceptionally cheap fuel to justify a forty mile round trip!

He stopped for petrol on his way elsewhere. Had to get his mate to bring him the key.

Ha! So it could have been worse if his next stop had been a hundred miles away.

I couldn’t say specifically for the DS5 but any other car i have tried this on the engine will stay running with the key out of range until you switch it off and as far as i was aware all cars with proximity keys should stay running without the key present. As said above this would be a safety issue, imagine the fob battery was weak, the car could then just conk out any time.

I would expect them to use RFID for starting/disabling the anti-theft thingy.
Daughter's Megane would start and run without problems although the fob wouldn't unlock the car due to a dud battery. Had to use the 'secret' manual key.
