L4V slamlock with its high-security key

Locks 4 Vans · Van Locks & Security

L4V Slamlock

Locks the door automatically the moment it closes, so it's never left open by mistake.

Locks when the door shutsThatcham-accredited T-seriesOnly that door opens

A slamlock locks the door automatically as soon as it's shut, with nothing for the driver to remember. After that it only opens with its high-security key. That makes it ideal for tradespeople going in and out for tools, and for couriers and multi-drop drivers. And because each slamlock opens only its own door, you're not unlocking the whole van every time you grab something from the back.

What the L4V Slamlock Does

Automatic locking

The door locks itself the moment it's shut, so it can't be left unlocked by accident.

Key-only opening

Once locked, the door opens only with the slamlock's high-security key.

Opens one door, not the van

Unlike central locking, which can unlock every door, a slamlock opens only the door you choose.

Built for busy days

Ideal for trades, couriers, parcel and multi-drop work, where the van is opened many times a day.

Thatcham-accredited cylinder

Uses the L4V T-series lock, which is Thatcham accredited in both slamlock and deadlock versions.

Keyed alike

It can be keyed alike with other L4V locks, so one key covers the whole van.

How It Protects You

Shut the door

The slamlock latches and locks automatically.

Walk away

There's no key to turn and nothing to forget.

Open with the key

Only the high-security key opens that door, and only that door.

L4V Slamlock Questions

The door locks as soon as it's closed, so always keep the slamlock key with you. That's the trade-off for never leaving the van open by accident.

Your fob still operates the van's own locks, but a door fitted with a slamlock also needs the slamlock key to open.

Anyone in and out of the van all day: trades, couriers, parcel and multi-drop drivers.

Around an hour per lock on most vans. We'll confirm when you book.
