Keyless Locking?

[millie80r]

Hi - I have a new B-Class, obviously with a keyless fob.
Should the car lock automatically when I walk away from it with the fob?
Mine isn't doing this.

Thanks.

Things like this are covered in the hand book

Yes - and when you can't find the answer in the massive handbook, you turn to 'helpful' and 'friendly' forums like this. It's the modern way.
Are you sure 'moderator' is the right job for you?

Are you sure sarcasm is the right way to get help? The point is that there are so many variations of features on even the same model of MB. It may be that you have to enable locking through Comand, only the handbook will tell you. But in any event it's simple to press a button when you leave the car -no?

In some cars there is a button on the handle which locks the car. Usually covered with a rubber weather protector (and prone to failures).
Some cars you just touch the door handle sensor to lock.

As far as I know no MB does as you're describing for safety reasons.

As mentioned usually covered in the handbook.

For security reasons I'd recommend disabling it. Keyless go systems from all manufacturers are notoriously easy for thieves to have your car away.

I didn't start off with sarcasm, I asked a perfectly simple and civil question but I didn't get help then either.
The point is that I've had 3 other cars with keyless entry and they've all automatically locked as soon as you step about 3 metres away. It seems to be Mercedes that doesn't do it and therefore it seems like an omission to me.
And no, if you're used to just walking away with the key in your pocket pressing a button is something quite important that you have to remember and start doing.

Thanks. There are sensors on the door handles which are easy to touch - if you remember. I've had 3 previous keyless cars which all lock when you step 3 metres away and I find this very convenient.
It makes no difference to the security as the fob can be cloned anyway unless you put it in a secure case after you've locked up.
Thanks again.

Disabling keyless go is the best way to stop someone just using a single repeater to fool the car into thinking the key is present when it’s actually not. Repeaters are less than £50 for a good one these days which to an organised gang is nothing to get the cars they want (you’d be surprised how many average family cars that is too).
It’s a nice gimmick but in reality so so insecure

I love keyless systems because you never need to take the fob out of your pocket. I have had it with Ford, Honda and Mercedes cars, but none of them have a walk away and lock function....in fact I have never even heard of this.
You need to touch your finger against the pad on the door to lock it, or use the less convenient method of pressing the button on the fob.
If the vehicle is unlocked but a door is not opened within a set time period (usually around 10-30 seconds) then the vehicle will automatically lock itself again.

Some people have a multitude of keys on a keyring along with their fob for their keyless car and place the whole thing inside the vehicle while driving, which means they can get out of the car and leave the keys where they are....now this to me is just asking for trouble...but each to their own.
I have my fob on its own and simply keep this in my pocket at all times.

Thanks. I love them too.
Renault and others call their systems 'Proximity' keys.
Like you say, totally convenient because you can keep it in your pocket but these are even more so because you just close the doors and walk away and you hear it lock.
I'm the opposite to you because I thought all keyless systems did this which is why I asked the question. It seems like a backward step but I'm sure I'll get used to it.
At least I can check (and lock) by looking at the app on my phone.
Thanks again.

That is interesting to know...you learn something new every day.
I have never owned a Renault, and probably never will.
The only problem for me with the walk away and lock function would be my anxiety in wondering whether the car had actually locked if for whatever reason I hadnt heard it.
For that reason I am more than happy to touch my finger against the pad to see and hear it locking before walking away.

You would definitely hear it because it locks as soon as you're just 2-3 metres away, gives a wee 'peep' and the lights flash and the mirrors tip in at the same time too.
And if you're still unsure, you can resort to pressing the button on the fob.
Great system.

Nissan do proximity licking too (hardly surprising as it's an offshoot of Renault).
The only problem wit proximity licking 8s when you get out the vehicle with your key and you still have a passenger in the vehicle. Seen more than a few at petrol stations with the alarm going off as the driver has gone to pay.

The security issue is as mentioned above and can happen at any time. For example you go to a car park and as you walk away another person walks slightly behind or to the side or stops and asks the time. In his pocket/laptop bag he may have one end of a pair of keyless extenders, the other being in the hands of an accomplice standing next to your car. His box of tricks he has pucks up the signal from your key and relays it to his accomplices box of tricks which retransmits the signal. The car thinks you're nearby so unlocks, let's the accomplice in who then rapidly starts the engine. The person near you says thanks and walks off. By the time you're at the carpark exit your cars already out a different carpark and away.

Sound far fetched? It does happen.

Hi
Thanks for your response.
I agree with your first point and yes, that scenario has happened to me on a few occasions.
Your second point is also valid and I concede that it does happen but it's really not an everyday occurrence.
Being used to the convenience of the proximity key, if I had the choice, I would take it every time and I'm sure others would too once they had experienced it.
It's just progress which we all get used to, otherwise we would still long for a starting handle and choke.

Thanks again.

Steady on....I am old enough to have experienced a choke, but a starting handle is a whole previous generation* or more!

You could tell it's locked if the mirrors are folded. I havn't the courage to just hope that it locks automatically though, I would rather know it's locked by physically doing it myself. As you say you've only got to touch the outside of any door handle anyway, not too difficult surely

I've had 2 vehicles with starting handles....


If you look carefully at the top one you can see it mounted just above the grille.

I never tried it though. The thought of using a crank handle on a V8 didn't appeal.....

I used it on my 2.25 petrol 88” it’s not something you do without due care and attention…
