Original description

This is a video demonstration of the security products that we fitted to a Mercedes Sprinter 2016 van. We fitted an alarm system that operates from the Mercedes remote control with sensors in the cab and a load (cargo) area PIR detector. In addition to this we fitted alarm switches to the top of the side load door for early detection of the door being folded (peel and steal attack).

We also fitted physical security deadlocks, OBD Port protection, an ECU shield and a Catalytic Converter protection Catloc device and also a set of rear parking sensors.

Note: Whilst we take great care in selecting products and techniques that we believe are effective to increase your van's security, we can never guarantee that any van is safe from a break in, please see our website for full terms and conditions.

Historical context: This video records the advice, products and attack methods relevant when it was published. Current recommendations may have changed as vehicles, products and criminal methods evolved.

Common questions

Why was the alarm door switch fitted especially high on this Sprinter's side load door?

Jeff notes this particular Sprinter doesn't have an extra catch on that door, so having the switch positioned high and triggering early was extra important to catch a folding attack before serious damage was done.

How does someone actually steal a Mercedes Sprinter by accessing the ECU, and how is it protected here?

Because Sprinter keys are all physically identical and only the electronics differ, a thief can bring their own pre-paired ECU, plug it straight into the wiring loom under the bonnet and drive away as if it were their own van, so Jeff fitted a heavy-duty shield over the ECU bolted down with shear bolts, since the ECU itself sits behind only a plastic wheel-arch trim.

What alarm upgrade was fitted to work with the Sprinter's own remote control?

An alarm system upgraded to arm and disarm from the manufacturer's original remote, with ultrasonic sensors added in the cab, a PIR detector in the load area, and an ultra-bright flashing blue LED on the dashboard to show the alarm is active.

0:00 -hi I'm Jeff Scott from sussex
0:02 -installations I show what we've been
0:03 -doing in the workshop today we've been
0:05 -doing a security mission on this
0:06 -Mercedes Sprinter so to start with we
0:09 -fitted extra locks on the doors these
0:10 -are our T-Series faction approved
0:12 -Deadlocks so if someone gets past the
0:14 -manufacturer's lock in the door open
0:16 -just opens a couple of millimet and the
0:18 -deadlock has the door
0:20 -secure we fitted one of these on each of
0:23 -the doors this is six side load door and
0:26 -it's the twin rear barn doors at the
0:28 -back this is actually a internationally
0:31 -one from the Netherlands so the side
0:33 -side load doors on the other side extra
0:35 -lock this is the driver's door same
0:37 -thing extra lock on there so if the
0:39 -manufacturer's locking gets breached it
0:42 -just goes a couple of millimeters and
0:43 -the deadlock has it secure what we've
0:45 -also done to this is we fited an alarm
0:47 -system this alarm system is upgraded to
0:50 -work from the manufacturer's original
0:52 -remote control so if I press the lock
0:53 -button it locks the alarm turns on and
0:57 -there's also an ultra bright flashing
1:00 -blue LED on the dashboard just to let
1:02 -everyone else know that the alarm's on
1:04 -WE fitted the ultrasonic sensors in the
1:06 -cab which go up on the top of the
1:08 -pillars and it obviously has the
1:10 -switches already on the doors so each
1:12 -door has a switch but we've done a
1:14 -little bit more than just that
1:17 -so the load area of this and if you just
1:20 -come around with me here so this side
1:23 -load door so to start with obviously
1:25 -we're worried at the moment about
1:26 -folding of side load doors so we fitted
1:28 -an extra switch right up the top in the
1:31 -corner here on the side load door so
1:34 -that switch I don't know if you can see
1:35 -that there would just protect if anyone
1:37 -starts to pull on the top of this door
1:39 -to try and fold the door over the switch
1:42 -is going to go nice and early and set
1:43 -the alarm off so given an early warning
1:46 -that the that hopefully they don't
1:48 -progress and damage the door by pulling
1:50 -it down that the alarm goes off early
1:52 -enough to stop them should they actually
1:54 -get past um the door by folding it or
1:57 -should they be able to climb inside the
2:00 -the van by cutting a hole through the
2:01 -roof or cutting a hole through the side
2:02 -of the van we've put a p detector in it
2:04 -too so this PR detector will detect
2:08 -movement in the rear of this van any
2:11 -movement in the rear of this van will
2:12 -set off this P detector which will
2:15 -trigger the alarm system which we fill
2:17 -in so we secured the locks on the doors
2:19 -secured the doors with extra Deadlocks
2:21 -we've put the alarm system that works
2:23 -from the factory remote control we put
2:25 -the extra sensor in on the load area the
2:29 -p we put the door switch up high on this
2:32 -side lad door of this Sprinter because
2:33 -this is the not the highest one it
2:35 -doesn't actually have an extra catch on
2:36 -here so extra important to have that
2:39 -that on this Sprinter next thing to show
2:42 -you is actually underneath the Bonnet so
2:44 -if I just crack the Bonnet there's a
2:46 -couple of extra vulnerabilities here
2:49 -with this van one of
2:51 -them is the ECU so I think the Sprinter
2:56 -problems of people stealing the van
2:58 -aren't necessarily the same as other
3:00 -makes and models where where they code
3:03 -new keys to the van but what they can do
3:06 -it seems is to bring their own ECU with
3:08 -them because the key is just like a a
3:10 -generic key they're all the same
3:11 -physically it means that any key will
3:13 -actually fit the dashboard so it's just
3:15 -the electronics that change so if they
3:17 -was to come along a thief with their own
3:19 -ECU that's already paired up to their
3:21 -own set of keys then what they could do
3:23 -with that is they could actually just
3:25 -plug it straight in to the to the wiring
3:27 -loom here and drive away as if it's
3:30 -their own van so what we've done we've h
3:32 -a big heavy duty Shield there I don't
3:34 -know if you can see that Shield over the
3:36 -ECU but there's a real big heavy duty
3:38 -shield and that's bolted on with Shear
3:40 -bolts because access to this ECU is
3:43 -quite easy there's um there's actually
3:45 -just a plastic trim on the wheel Arch
3:47 -here and then of course by opening up
3:49 -the Bonnet they'd be able to get through
3:50 -it anyway another thing which seems to
3:53 -be a real big expensive pain is if there
3:56 -was to get in and steal the cataly
3:58 -converter so you probably can't see it
4:00 -very well in the dark here but we fitted
4:02 -a a cat lock to this vehicle to keep the
4:04 -catalic converter safe from FF which
4:08 -would be a big expensive inconvenience
4:10 -should that get stolen um another thing
4:13 -that we did while we was at it was
4:14 -actually not a security product but a
4:15 -convenience product we we fitted parking
4:17 -sensors to this to this van as well so
4:20 -there's extra sensors on the the bumper
4:22 -very strange configuration this one with
4:24 -a step to the right so we've had to
4:27 -adapt with that and put a sensor on the
4:29 -step twoo
4:30 -so it's been a hard day's work but me
4:33 -and the the the guys the team we've been
4:35 -on it today we've got this van secure we
4:37 -got the convenience of Those sensors we
4:39 -got the cap lit converter secure um if
4:42 -you'd like products for your Sprinter or
4:44 -any other vehicle get in touch via the
4:46 -website it's
