Jeff Scott's retrospective context — 2026

We believe this to be the first ever video showing a slamlock fitted to a panel van where Jeff Scott clearly demonstrates how it operates and what type of van owner a slamlock is suitable for. This was at time where video, pictures of someone to demonstrate what a van slamlock is was almost impossible to find and this could end up with van owners purchasing security locking that wasn't really suitable for their needs; because of the lack of information. This video shows Jeff Scott director of Sussex Installations demonstrating how a Locks 4 Vans cylinder slamlock looks and functions when fitted to a van in that you have to use the key every time that you open the door of the van. This video explains the basic mechanical difference at the heart of a slamlock: close the door and it locks itself, with no key needed until you want to unlock it again. That single feature decides who a slamlock genuinely suits. Couriers are in and out of the van dozens or hundreds of times a day, often with a parcel in one hand, and their real risk is a moment of inattention around the back of the van while making a delivery. A slamlock removes the need to remember to lock up every single time.

Their biggest risk is freight being stolen from their vehicle when they're just around the corner delivering a parcel, waiting for a signature.

Tradesmen are a different case. Some suit a slamlock too, particularly if they or an apprentice are simply forgetful about locking the van during the day. But a tradesman who needs genuine overnight security should be looking at deadlocks as well, not a slamlock on its own. The lasting lesson from this video is one I still apply today: the right lock depends on how the van is actually used, not just what category of vehicle it is. I have seen that same question asked the wrong way round elsewhere too — a slamlock is excellent for a courier in and out all day, but it is a poor recommendation for a vehicle like a campervan, where being locked out of your own van a long way from home is a real and unwelcome risk.

Original, useful videos showing how van smalocks, van deadlocks and other van security products function published from as early as 2009 would by 2026 earn Jeff Scott (owner of Sussex Installations) the recognition of being 'The OG Van Security YouTuber'.

Common questions

What exactly makes a lock a "slamlock"?

A slamlock locks itself automatically the moment the door is closed, with no key needed to lock it — the key is only needed to unlock it again. That is the one defining feature that separates a slamlock from a deadlock.

Who genuinely benefits from a slamlock, and is it enough for a tradesman?

Mostly couriers, who are in and out of the van hundreds of times a day, often with a parcel in one hand. Their biggest risk is the van being left unlocked for a moment while they make a delivery, and a slamlock removes the need to remember to lock up every single time. It also suits forgetful tradesmen during the working day, but for genuine overnight security a tradesman should look at deadlocks as an additional layer, not rely on a slamlock alone.

Why trust Jeff Scott and Sussex Installations' advice on van locks?

Jeff Scott has specialised in van security since 2008, and this 2013 video is believed to be one of the very first showing how a van slamlock actually looks and operates, at a time when almost no video or photographic explanation of the product existed anywhere online. Jeff has been publishing original van-security education videos since 2009, work that would go on to earn him recognition as 'The OG Van Security YouTuber.'
