Someone trying to drive away in your campervan and someone trying to take the kit inside face different obstacles. A useful security plan has to make both jobs harder.
Vehicle theft and break-ins need different layers, because the device that slows one type of attack may do little against another. A steering lock, door security, immobilisation and tracking each have separate jobs.
That is also the direction of current police-backed advice. Secured by Design’s campervan and motorhome guidance recommends combining physical and technical security rather than relying on one device.

Build security in layers
A steering wheel lock can make the van harder to drive away, but it does nothing to stop somebody breaking a window and taking a laptop.
A deadlock can make a side or rear door harder to force, but it will not stop the vehicle being moved.
A tracker may help locate a stolen campervan, but by that point the theft has already happened.
Put those different jobs together and security starts to make more sense:
- visible deterrent – make the van look awkward to steal;
- physical barrier – slow down access or prevent normal driving;
- electronic security – alarm or immobilise the vehicle;
- tracking – improve the chance of locating it if the other layers fail;
- good habits – lock everything, hide valuables and think about where the van is parked.
You do not need every security product on the market. You need a sensible combination that you will actually use.
Start with something visible
A good mechanical lock has an advantage that an alarm or hidden immobiliser does not: somebody can see it before they damage the van.
That does not mean a steering lock makes a campervan impossible to steal. Its value is partly that it adds time and hassle and makes the next vehicle look easier.
Full-cover steering locks
Full-cover locks enclose most of the steering wheel rather than just clamping onto one section of the rim.
They are difficult to miss when looking through the windscreen and cover much more of the wheel than a simple bar-type lock.
The disadvantage in a campervan is obvious: they are bulky. You need somewhere to put the thing while you are driving and camping.
That matters more than it sounds. A security device that lives underneath bedding because it is a nuisance to get out will eventually stop being used.
Bar-style steering locks
A bar lock takes less room and is usually quicker to put on and remove.
That practicality is one reason some experienced motorhome owners still prefer them even though a full-cover design gives more protection around the wheel. In a 2026 MotorhomeFun discussion, several owners favoured equipment that was easier to store and fit regularly rather than something bulkier that might get left behind.
If compact storage matters, the Milenco HS Yellow steering wheel lock is a current Amazon UK option. It is best thought of as a visible extra layer, not as a substitute for every other security measure. Check the dimensions and fit against your own steering wheel before buying.
Pedal locks can add another barrier
A pedal lock or pedal box prevents normal use of the pedals and is another way of making the van harder to drive away.
These are particularly relevant to campervans because there are vehicle-specific versions for common base vans such as the Fiat Ducato, Peugeot Boxer, Citroën Relay and Mercedes Sprinter.
The important word there is specific. Gearbox type, model year and right- or left-hand drive can affect whether a pedal lock fits properly.
They are less visible from outside than a steering wheel lock, but that can also work in your favour: somebody who has already got into the cab then discovers another physical barrier.
The main downside is convenience. Fitting a pedal lock means reaching down into the footwell, so choose something you can realistically see yourself using regularly.
For Ducato and Boxer-based vans, the Centinel Clutch Claw pedal lock is one current option. The Amazon listing specifies Fiat Ducato and Peugeot Boxer from 2014 onwards, but pedal layout, gearbox and model year still need checking against your own van before buying.
If you have swivel seats, use them
A campervan already contains one possible obstacle that many cars do not: the driver’s seat may swivel.
Turning the driver’s seat away from the controls can make the driving position awkward to use. Secured by Design includes this as a campervan security measure and suggests securing the rotated seat where the installation allows it.
That does not cost much and does not take up additional storage space.
Any additional lock or chain around the seat needs to avoid the seat-belt mounting, wiring and normal operation of the seat.
Protect the side and rear doors
Panel-van conversions normally have several large doors: two cab doors, a sliding side door and rear doors.
Factory central locking is convenient, but additional deadlocks or hook locks provide a separate mechanical layer rather than relying entirely on the original locking system.
This can be particularly useful on the sliding and rear doors, where there may also be expensive equipment immediately behind them.
Deadlock fitting is one job where paying a specialist can make sense. The lock has to suit the door and be positioned correctly, and drilling holes into a perfectly good campervan door is not a job you want to repeat because the first position was wrong.
Owners discussing recent panel-van security upgrades commonly combine door deadlocks with an alarm, steering lock and tracker rather than seeing the deadlock as the whole solution.
Habitation doors and windows
Coachbuilt motorhomes and some campervans have a separate habitation door. There are additional locks designed specifically for these doors, but furniture, blinds and flyscreens can limit where they can be fitted.
Acrylic habitation windows are another weak point. Secondary catches and locks can slow somebody down, but remember what you are attaching them to. The lock itself might be strong while the window around it is still plastic.
The realistic aim is to add enough delay and fuss that getting inside is neither quick nor discreet, rather than pretending the living area can be turned into a safe.
For a separate habitation door, the Fiamma Safe Door external security lock is one current motorhome and caravan option. Check that the mounting position suits the construction of your own door and surrounding wall before drilling anything.
When adding extra internal security for night-time use, keep an easy way out. You do not want to create a complicated obstacle course between the bed and the door if you ever need to leave the van quickly.
Alarm, immobiliser and tracker are three different things
These terms often get bundled together, but they solve different problems.
Alarm
An alarm tells you – and everybody nearby – that somebody is interfering with the van.
For a campervan, check what the alarm actually protects. A system that only monitors the original cab doors may leave the sliding door, rear doors, lockers or habitation door outside the protected area.
Immobiliser
An immobiliser is there to stop the vehicle being started or driven normally.
Modern base vehicles already have factory immobilisation, but owners of high-value campervans sometimes add a separate aftermarket system as another independent layer.
Tracker
Tracking is mainly a recovery layer rather than a physical barrier. It becomes useful if the van is taken despite the other precautions.
There is a useful real-world example on MotorhomeFun from 2024: a Knaus panel-van camper was stolen, but the owner had a tracker and recovered it the following morning. The ignition and trim had been damaged, but the vehicle itself was located.
That is a good illustration of what a tracker is for. It is the backup plan when prevention has failed.
For a self-installed recovery tracker, check compatibility with the van’s electrical system and any ongoing data or subscription requirements. If your insurer requires a particular approved tracker category, use whatever the policy actually specifies.
What does Thatcham approval mean?
If you start comparing alarms and trackers, you will quickly run into Thatcham categories.
Thatcham Research currently certifies several types of vehicle security equipment, including:
- Category 1 – combined electronic alarm and immobiliser;
- Category 2 – electronic immobiliser;
- Category 2-1 – electronic alarm;
- Category 4 – wheel locking devices;
- S5 – vehicle tracking systems;
- S7 – asset location systems.
Thatcham certification means the product has been assessed against defined security criteria. It does not automatically mean every insurer accepts every certified product.
That leads to one of the most useful rules in this whole article:
Check with your insurer before spending serious money on an alarm, immobiliser or tracker.
If your policy requires a particular class of tracker or security device, fit something that satisfies the actual policy rather than buying first and asking afterwards.
Our DIY campervan insurance guide is also worth reading if the van is self-built or heavily modified.
Keyless entry and Faraday storage
If the base vehicle has passive keyless entry and start, the key can be part of the security problem.
A signal-blocking Faraday pouch or box is a simple additional layer for keys that continuously communicate with the vehicle.
The Samfolk Faraday box and pouch set is one current Amazon UK option and includes a box plus two pouches.
Whatever Faraday product you use, test it rather than trusting the label. Put the key inside, close it properly and take it to the van. If the vehicle still detects the key normally, the signal is not being blocked effectively.
A Faraday box only tackles the keyless signal problem. It does not replace the steering lock, door security or the rest of the system.
OBD-port protection
Another security measure you may come across is an OBD lock or guard.
The diagnostic port is useful for servicing and fault finding, but on some vehicles it can also be part of the route used to attack the vehicle’s electronic security.
A physical guard makes access to that port more difficult.
This is very vehicle-specific, so check what is available for your exact base van and whether it interferes with normal servicing access before fitting one.
Security at home matters most
A campervan can spend weeks sitting in the same place outside the house, so your driveway or storage arrangement is part of its security.
Useful measures include:
- close and lock gates where you have them;
- use a security post or bollard where practical;
- park so the van cannot simply be driven straight out;
- use decent motion lighting;
- consider CCTV covering the parking area;
- keep the vehicle keys and spare keys away from doors and windows;
- remove documents and obvious valuables from the van;
- still fit the visible mechanical lock even though the van is at home.
Secured by Design also recommends restricting access with gates or a bollard and using CCTV where appropriate.
If a removable post suits the driveway, the Maypole heavy-duty removable security post is one current example. It is designed to be concreted into stable ground and removed when vehicle access is needed. Check for buried services before choosing the position.
If you have the choice, think about how the van would physically have to leave the property. Adding one awkward manoeuvre can be another small layer.
Security when you are travelling
Once you are away from home, theft from inside the van becomes just as relevant as theft of the whole vehicle.
Before walking away:
- lock the cab, side and rear doors;
- close windows and rooflights;
- fit the steering or pedal lock;
- keep phones, cameras, laptops and wallets out of sight;
- do not hide the spare vehicle key somewhere inside the campervan;
- keep important vehicle documents somewhere sensible;
- choose busy, well-lit parking when you have a choice.
It is easy to think, “I’m only going into the shop for ten minutes.” Unfortunately, that is exactly when a quick visible deterrent earns its keep.
Bikes and equipment on the outside count too
A campervan may be secure while two expensive e-bikes are sitting on the back.
Bike racks, roof boxes and rear storage boxes therefore need their own security. Use a proper lock through a solid part of the bike or equipment rather than relying only on a rack’s small built-in lock.
If bikes are particularly valuable, consider how visible they are when the van is parked overnight and whether they can be brought inside or covered.
For a higher-value bike or e-bike, the Burg-Wächter 1m Sold Secure Gold chain and lock kit is one current option. A good lock still needs to go through a solid part of the bike and, where possible, around something more substantial than a lightweight rack fitting.
Don’t advertise what is inside
Many break-ins are about the contents rather than the vehicle itself.
A laptop on the table, camera bag on a seat or expensive tool case visible through a window gives somebody a reason to get in.
Keep valuable items out of sight and think about where important things live inside the conversion. A securely fixed hidden compartment can be more useful than another flimsy cupboard catch.
Our campervan storage ideas article has more ideas for using awkward spaces inside a conversion.
It is also worth photographing expensive equipment and recording serial numbers. If something is stolen, identification is much easier when you have those details already.
What I would spend money on first
You can turn campervan security into an expensive hobby very quickly.
For most DIY panel-van conversions, a sensible order is:
- A visible mechanical lock – something you can fit quickly and will genuinely use.
- Use the van’s existing security properly – working central locking, alarm and immobiliser where fitted.
- Improve vulnerable doors – vehicle-specific deadlocks or hook locks where justified.
- Add tracking for a valuable van – especially when the insurer requires it or the van is stored away from home.
- Deal with keyless entry if you have it – tested Faraday storage is cheap compared with the rest of the van.
- Improve home parking – gates, lighting, bollards or CCTV where they suit the property.
After that, pedal locks, OBD protection, wheel clamps and further door or window security can be added according to the van and where it spends its time.
This order will not suit everybody. A classic VW, a new £80,000 coachbuilt and a self-build Boxer parked behind locked gates do not have the same risks.
Choose security you will genuinely use
This point came up repeatedly when reading owner discussions.
A large full-cover steering lock may offer excellent visible protection, but if you find it so awkward that it stays under the bed, a smaller device fitted every time may be more useful in the real world.
The same applies to wheel clamps, pedal locks and removable security posts.
Before buying something, ask two questions:
- where will I store it while travelling?
- will I actually fit it every time I leave the van?
Campervan security has to work around campervan life.
Campervan security checklist
Before leaving the van:
- ☐ Cab, side and rear doors locked
- ☐ Windows and rooflights closed
- ☐ Steering or pedal lock fitted
- ☐ Alarm armed where fitted
- ☐ Tracker active and subscription current where required
- ☐ Valuables out of sight
- ☐ Spare vehicle key not left in the van
- ☐ Bikes and outside equipment locked properly
- ☐ Keyless keys stored in a tested signal-blocking pouch or box where relevant
At home:
- ☐ Gates or security post used
- ☐ Van parked in the least convenient direction for removal
- ☐ Keys kept away from doors and windows
- ☐ Lighting/CCTV working where fitted
- ☐ Vehicle documents removed from the van
Final thought
No security measure makes a campervan impossible to steal.
The aim is to make yours slower, noisier and more awkward to attack, while having another layer ready if the previous one is defeated.
A visible lock discourages the first attempt. Better door security slows entry. An immobiliser makes driving away harder. A tracker gives you a chance of finding the van if all of that still fails.
The final layer is routine: use the equipment every time.
Choose a combination that suits your van, your parking arrangements and the way you actually travel.
