Keyless entry - paranoid about theft

[salis]

Hi guys,

I bought a GLE 43 Coupe and I’m very paranoid about the keyless entry - I guess it’s very easy for someone to intercept the signal coming from the key fob and car can be easily stolen.

Is there a way to disable the keyless entry?

Are there any small RFID blocker cases that simple cover the key fob, rather that big Faraday cases?

Thanks in advance!

If it's the same as the c63 if you double click when locking the car it disables the keyless entry plus there are pouches on ebay to put the key in

Are they called Faraday cases ?

And the most stolen car in the UK is.....






The Ford Fiesta .

Could also be called "a piece of aluminium foil" wrapped around the fob or a small "metal box".

Do not forget the shield the spare key as well,just get into the habit of hitting the lock button on the fob twice and then you would need to press the button again to get entry to the car and so stop anybody trying to boost the key signal,also the latest MB cars keys go dormant after a while and so they cannot be boosted because they are not giving out a signal on the table in your house or the pocket of your coat.

There’s loads on Amazon which vary from fabric pouches to fancy tins/boxes. I bought a pack of two pouches for my last car, one for my in use key and the other for the spare. From memory I think it was around £9/10 for the pair. The only thing to watch for is the size, especially if you have other keys on a key ring, the ones I bought weren’t the biggest, and also test them every so often by taking them to your car and trying to unlock it. I remember people mentioned the fabric ones can fail over time especially if you carry it in a pocket, I guess the blocking lining can become damaged due to bending and flexing, I never carried mine around, but for home use and the piece of mind they are well worth the money.

If you double-click the locking button on the key, it disables the radio on the key thus keyless entry is disabled for that key. There is therefore no need to put it in a Faraday pouch too.

What is important is that the OP also double-clicks the locking button on the spare key too before putting it in a draw (or wherever) at home. That way, there will be no active keys near the car that can be used for a relay attack to open the car.

BTW, the key doesn't need to be anywhere near the car when it's double-clicked to disable its radio.

They keys actually go to sleep after a while when not moving, so relay theft isn't possible. I also keep my keys in a metal Roses tin.

I would highly recommend a Ghost II immobiliser, small change compared to the cost of the car.

faraday cases work, you can get faraday boxes, so in the house just chuck the keys in the box and close the lid.

Also get a steering lock!

Ghost immobilizer, steering lock (the after market one that sticks on the wheel?), gets complicated compared to using KG only. I've never even had any alarm in my cars (no MB OEM alarm). I'll let you know now that my next car has the MB OEM alarm (standard now for us, otherwise I would have skipped).

What is KG?

Thanks all for the replies, really helpful!

Keyless Go

Keyless Go

So you just double lock it I guess. I will do that too

It won't stop someone intercepting the frequency , but it will stop them from using keyless go. If they want your car bad enough , they'll get it .

Probably worth clarifying that only applies to the latest keys so people should check what their key does... All the info is in the manual, which can easily be searched using the mercedes guides app on phone

The level of anxiety depends on whether your car is not garaged or habitually spends its time in motorways service stations or dodgy car parks in dodgy areas. Even if garaged it's best to apply a steering lock & store the key in an indoor Faraday pouch. At service stations having fitted the steering lock, lock the car & place key in small Faraday pouch whilst still close to the car & before walking away. Ditto dodgy parking areas but ideally avoid them. In the past I have run an old banger for supermarket shopping & short journey errands & a short work commute. Probably not good for my ego or to impress friends, neighbours or work colleagues but then I couldn't care a toss what others think. I guess if I did live in a rough area I would spend my money on moving away.

Ghost is the best thing in my opinion. Nobody can steal your car unless they lift it onto a tow truck. You can now get a fob for your ghost as well rather than entering a code each time and the fob works only when you are in your car. All approved dealers charge the around same price so don't use anybody who seems really cheap.

Some dealers may fit a second hand unit slightly cheaper. Check out their website for approved dealerships

Seems it is connected to the interior CAN, sniffs messages and lets them pass if deactivated. An average joe would not know what is going on but an average thief would know where the CAN distributors are and fix the wiring to original. Not much more security than in the past when an alarm relay cuts the starter solenoid drive.

Please convince me, there must be more than I figured out.
