C63s Edition 1 Stolen - Key Less Owners Warning
I thought I would share the recent theft of my 2015 C63s Edition 1 Car with you and the warning of owning a key less car.
The car was stolen in the early hours of the 6th April from Woodford Green in London. I have CCTV and the thief's just walk up to the car, unlocks it and drives it away. I am not sure if they had a copy of the key since the car was in the Loughton dealership 2 weeks back. Or they are the radio codes for my particular car.
Another guy is seen standing in front of our house door, to prevent any interruption of the car being stolen.
It was taking in 60 seconds!!!
Here are the CCTV videos if anyone is interested
Luckily i was able to get an image of the suspect outside the house. Here is the Facebook link for it. Please share it if you live in the UK and especially London.

I urge anyone who has a key less car to buy an old fashion steering lock. They can be a deterrent for this type of crime.
I had a Mercedes tracker installed (tracker locate) and shortly after realising the car was stolen, I had come to the conclusion that it was the biggest waste of money ever. The tracking company 1st took 2 hours to send the signal to the car to turn on its tracking beacon (as they needed authorisation from the police) and when they did send the signal, there has been to date no response from the car!
If you have the Tracker Locate system on your car, please read up on how that system works and see if it fits your needs especially if the car is stolen. I know of other systems that are active as soon as the ignition has started.
I thought I would share my story. I am pretty gutted to have lost that car.
In US MBrace app can track your car once it leaves a prescribed area.
Jammers are effective - 600 USD and you can buy handheld jammer which covers all available commercial frequencies.https://www.jammer-store.com/titan-a...-solution.html To make the selling of a stolen car more expensive, I have security marks (windows + invisible markings)http://www.any.hu/en/solutions-2/ide...arking-system/. However nothing can prevent a determined thief - homejackings are rather common here in Europe. Thus better to have a good insurance policy.

Ive also got keyless go, so was really surprised by your article, I never thought people would of been able to get blanks of keys firstly without supplying a vin and then be able to clone your own key secondly !
Does anyone one know how people are doing this ??
But, in the OP's case, I don't think this is what they did. It looks like the guy who waited by the front door had a receiver and basically it increases the range of the key fob from inside the house. Thus, allowing the guy near the vehicle to unlock it and drive off.
There is videos on YouTube of how both these methods work. Easiest way is to park inside of garage if you have one at your home, or simply remove the keyless go start button. (Won't do much if they have their own button, but still worth a shot)




This is a known vulnerability in many of the new keyless entry vehicles, and none of the manufacturers have addressed this security vulnerability to my knowledge.
There are also China-sourced handheld devices that robbers can use by plugging into your OBD2 Port and disabling any factory/OEM ignition kill/immobilizer/alarm system, and start the engine. I saw this operate in real time on a show on the National Geographic Channel.
As for locator devices, the factory units aren't adequate, because anyone who's half decent and is looking to steal a high end car like a C63 will know what factory features it has, and how to disable it. The aforementioned show mentions how they have insiders they can call and actually remotely disable your factory immobilizer.
Best thing I can think of (short of parking indoors) is to have a tracker with geofencing, meaning anytime the vehicle is moved from the limited location you specify (whether it's driven, towed, or whatever), the tracker is activated and sends you an alarm.
OP, sorry for your loss...

What FDNewbie has said does make sense "They're hijacking the unlock frequency your keyfob uses to unlock/lock the car"
However I typically lock the car using the handfree locking, rather than pressing the lock button on the remote. My belief is that they had someone on the dealer network involved. The car was in the Loughton Garage a week before it was stolen. They disabled the command online GPS (or jammed it) and the tracker signal has still not reached the car. And the tracking company are advising that their tech is resilient to jamming devices.
When locking vehicle hit lock button 2 times till you here the horn chirp twice and flash a red light on fob twice .
Now the signal from your key fob is deactivated.
Do the same to your spare key fob.
Every time you go somewhere or home,must keep doing this so that they can not amplify your key fob signal to steal your car.

Go to dealer let them know about it

Lastly, you can remove the antenna on top of the roof and the entire MBrace system is rendered useless. I know when my buddy's M5 was stolen the shark fin (antenna) for BMW Assist on the roof of the car was completely ripped off. They noticed this when the car was recovered two weeks later totaled. BMW Assist could never establish connection with the car.
Sorry for the loss OP. Do keep us updated with any further info you get.

Your key doesn't need to be near the front door. If it is within range 50 feet or less~ the amplifier the thieves use will pick it up and extend the range. The article FDNewbie explains in great detail. Those trackers are pretty much useless. We have LoJack here in the states and they are easily defeated. You can pick up a frequency jammer for those with a simple search on Google. These can also be used to help locate the tracking module inside the car for it to be unplugged.

They don't tell you how easy the tracker devices are to overcome when they are being sold to you.
I have a call with Mercedes planned today, just waiting on a call back.

just do the same for your spare fob. also extends battery life on fob.
just to let you know every time you unlock your vehicle the fob [aka- using the fob manually] and car are in sink so the codes are constantly changing together.

I did a little research and it seems this is much more prevalent in EU than is the USA... but another way to protect yourself is by putting your key fob in a protective sleeve or bag.
Just do a Google search or Amazon search and there are plenty to choose from. Anywhere from $10 to $30 for a pouch.

Is there a way around it? Eg once the tracker "loses a signal" ie by the jammer, it immediately goes into alarm/notify mode?
I know some trackers have other options like ignition kill, fuel cutoff, oil cutoff, etc. Maybe if there's a way to have these in "kill" mode by default when armed, and manually disabled when disarmed? Just a thought...

Got a link for this? I thought one of the advantages of LoJack was it's a radio frequency, so you don't need a GPS signal at all (and thus isn't affected by GPS jammers)?
You're not talking about just a simple rubber keyfob protector, are you? I'm guessing you're referring to something that protects it from anyone trying to communicate with the keyfob? Never heard of this...
also you can jam radio frequencies just as easy.

This sucks. I thought trackers were the way to go...
Can't even protect the cars in a garage either, cuz the garage door frequency can be stolen as well...
