If you keep tools in your van overnight, the factory locks are not enough. Modern trade vans are peeled, drilled and pried open in under a minute, and once your kit is gone you are off the road, out of pocket, and arguing with an insurer who wants to know why you did not fit an aftermarket lock. This guide ranks the best van deadlocks and slamlocks you can fit in the UK in 2026, explains the difference between the lock types, and tells you what actually stops a determined thief.
Quick Verdict
Best deadlock overall: Locks 4 Vans T-Series Deadlock — the standard fitters and fleets trust, tough to drill and pick.
Best slamlock for multi-drop: Locks 4 Vans T-Series Slamlock — locks itself every time the door shuts, so you never forget.
Best for peel attacks: Armaplate with an anti-peel plate — protects the OE lock area, not just the door edge.
Best DIY-fit: Van Guard Ultimate Van Deadlock — vehicle-specific bracketry, fit it yourself in an afternoon.
Best budget: Milenco High Security Van Deadlock — visible deterrent for less, ideal for a second van or occasional storage.
Deadlock vs Slamlock vs Hooklock — the difference that matters
Get the type right before you spend a penny, because they solve different problems.
A deadlock is a separate lock with its own key, completely independent of the van’s central locking. You lock it manually when you leave the van. It throws a solid bolt into a receiver, so even if a thief defeats the factory lock or the alarm, the door still will not open. It is the strongest option for overnight and driveway security.
A slamlock locks automatically the moment you shut the door — no key, no button. That makes it the go-to for multi-drop drivers, couriers and anyone in and out of the load area twenty times a day. The trade-off is that it is easy to lock your keys inside, so most fitters set them up keyed-alike with your deadlocks.
A hooklock (or hook bolt) is a variant that throws a hooked bolt rather than a straight one, gripping the door frame so it resists being sprung or jemmied apart. Many L4V and Armaplate kits use a hook bolt for exactly this reason.
Anti-peel plates and repair plates are not locks at all, but they belong in the same conversation. The most common attack on a modern van is ‘peeling’ — bending the door skin back around the OE lock to reach the mechanism. A steel plate over that area blocks the attack. Pair one with a deadlock and you have covered both the common and the brute-force routes in.

The picks in detail
Locks 4 Vans T-Series Deadlock — best deadlock overall
If you ask ten van security fitters what they put on their own vans, most will say Locks 4 Vans. The T-Series uses a dimple key with anti-pick, anti-drill cylinders and a hardened hook bolt that grips the frame rather than just sliding across it. It is the closest thing the trade has to a default choice, which also means keys and replacements are easy to source anywhere in the UK. Fit one to each rear and side load door and your kit is genuinely difficult to reach without an angle grinder and a lot of noise.
Locks 4 Vans T-Series Slamlock — best for multi-drop
Same cylinder quality as the deadlock, but it locks itself the instant the door slams. For a courier or delivery driver making dozens of stops, that removes the single biggest risk: a door left unlocked in a hurry. Set it up keyed-alike with your deadlocks so one key does everything, and keep a spare somewhere off the van, because locking your keys inside a slamlock is a rite of passage you only want to go through once.
Armaplate with anti-peel plate — best against peel attacks
Armaplate’s strength is that it tackles the attack thieves actually use on newer vans. The kit armours the vulnerable OE lock area with a steel plate and adds a hook deadlock, so peeling the door skin back gets a thief nowhere. It is available through specialists like Vanlocks.co.uk and can be self-fitted if you are handy, or professionally installed. If your van is a common target model (Transit Custom, Vivaro, Transporter), this is the sharpest value for the threat you face.
Van Guard Ultimate Van Deadlock — best DIY-fit
Van Guard designs vehicle-specific bracketry, so the deadlock lines up with existing mounting points and you are not drilling blind. With basic tools and an afternoon you can fit one yourself and save the labour cost. The bolt and cylinder are not quite to the pro-fit standard of L4V, but for a driveway-parked van it is a strong, sensible deterrent at a fair price.
Sussex Installations slamlock — best fitted service
Some jobs are worth paying to have done right. Sussex Installations fit L4V and other systems with a workmanship guarantee, which matters if your insurer wants proof of professional installation. You are paying a premium over a DIY kit, but you get correct alignment, a warranty and someone to call if anything sticks.
Milenco High Security Van Deadlock — best budget
For a second van, a rarely-loaded van, or simply a visible deterrent on a tight budget, Milenco’s deadlock does the job for less. It will not defeat a determined grinder attack any better than the pricier options, but the vast majority of tool theft is opportunist, and a bolt-throwing deadlock on the door is often enough to send them to an easier target down the road.
Buyer’s Guide: what to look for
Check your insurance first. Many trade tool policies now require an aftermarket deadlock or slamlock, and some insist it is professionally fitted with a receipt. Fitting the right lock can cut your premium; fitting nothing can void a claim entirely. Read your policy wording before you buy.
Look for Sold Secure or Thatcham recognition. Independently tested locks resist sustained drill and pick attacks. Anti-drill and anti-pick cylinders should be standard in 2026 — if a lock does not mention them, walk away.
Cover every door. A deadlock on the back doors is pointless if the side load door is still on the factory lock. Price up all the doors you actually open, and remember multi-door fitting usually works out cheaper per door because the labour is shared.
Keyed-alike is worth it. Running slamlocks and deadlocks on one key across the whole van saves fumbling through a bunch on a cold morning. Specify it at the point of order — retro-keying later costs more.
Add an anti-peel plate on common targets. If you drive a model thieves love, the door-skin peel is the attack you will actually face. A plate closes that door, literally.
DIY vs fitted. A capable tradesperson can fit a Van Guard or Armaplate kit at home and save on labour. If your insurer demands professional installation, or you are not confident drilling your own door, pay a specialist — it is cheaper than a claim.
Frequently Asked Questions
Do I need a deadlock or a slamlock?
If your van sits overnight on a driveway or the road, a deadlock gives the strongest overnight protection. If you are in and out all day on multi-drop, a slamlock stops you ever leaving a door unlocked. Many drivers run both, keyed alike.
Will fitting a deadlock lower my insurance?
Often, yes — and some tool insurance policies now require one. Check your policy; a professionally fitted, recognised lock can reduce your premium and, more importantly, keep your cover valid if you are hit.
Can I fit a van deadlock myself?
Vehicle-specific kits from Van Guard and Armaplate are designed for DIY fitting with basic tools. Slamlocks and pro-grade L4V systems are usually best professionally installed for correct alignment and to satisfy insurers.
How much does it cost to have van locks fitted?
As a rough guide, expect around £130 per door fitted in 2026, with multiple doors working out cheaper per door. DIY kits start lower but you carry the fitting risk yourself.
What is a peel attack and why does it matter?
Peeling is bending the door skin back around the factory lock to reach the mechanism — the most common attack on modern vans. An anti-peel or repair plate over that area blocks it, which is why a plate plus a deadlock is the strongest combination.
The bottom line
For most UK tradespeople parking a loaded van overnight, a Locks 4 Vans deadlock on every load door — with an anti-peel plate if you drive a common target — is the security setup worth paying for. Multi-drop drivers should add slamlocks, keyed alike, so a door is never left open. Whatever you choose, fit something: the factory locks are the one thing every thief already knows how to beat.
