Keyless Security

[hangloose]

If I switched on the engine and left the vehicle unattended, anyone can drive it off right?

Does it mean Keyless is not a good security feature?

Please advise.

For keyless, once the vehicle senses that the key is not within the proximity of the vehicle, the engine will shutdown. If you leave the key in the car then I guess it doesn't matter if it's keyless or not, anyone can still drive the car away,

If I recall correctly, I think it's otherwise. If The key is outside the range. U can't shut off the engine. It will only shut down after there is totally no fuel.

Perhaps some seniors can confirm. Thanks

If I do not recall wrongly key not in range u still can drive for 20km before engine cut off. Need to double confirm with MB

Never really tried it before. Even if that's the case where you can drive the vehicle after it's been started and without the key fob in the car, it's exactly the same as someone without keyless leaving the engine on and leaving the vehicle. If you wanna be safe, I guess always shut the vehicle down when you're not around. As simple as that.

Lol... I tried before. It will warn and buzz repeatedly for about 10-15mins.

 

Then it won't give face and just shut down. (W221)

Once, when my w221 key fob battery low, "Key Not Detected" Red error appear while I'm driving. It will beep continuously while car still in motion until I stop at a traffic light. Then it cuts off engine straight away. Distance travelled between Error triggered and engine shutdown about 1 to 2 km cos I was turning out from expressway to a slip road traffic light.

I'm guessing for safety reasons, it won't just shutdown the car immediately when it's in motion.

Haha... mine was in motion when it decided to shutdown so don't think otherwise!

once i was driving my 2007 c200k to tampines with my mum and after which she drove it back to kallang with the car key still inside my pocket. then when she reach kallang she called me and gave me hell and had to drive back to tampines to collect the car key from me. no prompting or warning at all , but after i change ride to e250 coupe and w212 sedan whenever i leave the car with my keys it will prompt me saying something like car key not detected.

My dad sent me to air port. I forgot to pass him the keys. He drove back from Air port to Jurong. Safe and sound. W212.
