TrioVing Twin bumpable (ASSA-ABLOY)?

[oystlars]

I see there are earlier posts regarding TrioVing and wether these locks need slimmer picks than ie. US. The answer to that; House-locks (non-system 6-pin tumbler) - NO, System-locks (7-pin) - YES.

Now I was wondering of the TrioVing Twin series, are they prone to bumping?

I believe it can be done. But of course; the problem would be to get hold of blanks. But I guess one could use non-master keys and the Dremel tool..

I would guess yes, as it appears to be ASSA-ABLOY simply distributing their ASSA Twin product under a local name. There is a video of somebody bumping an ASSA Twin cylinder online.

As for getting the blanks however....

This twin system is closer to the schlage primus and ikon systems than the ASSA twin system. As far as bumping the lock goes, if it is like the primus then it can be done but attention must be payed when preparing the blanks as the sidebar must be in the precise correct position to open. I find that when bumping these locks that after striking the blanks that if I move the key slightly in and out with my fingers it is enough to release the sidebar if the key happened to go to deep while bumping.

This is just about to get too detailed for the open forums though !

Thing is, in sweden and norway, the sidebars are very often totally different (not like in other countries when an entire region can have the same sidebar). Almost every lock has its own unique sidebar, which makes the ASSA TWIN almost impossible to bump in sweden, and thus probably in Norway too.

My suggestion: Get/look at a lot of different keys and check out their sidebars. If a majority of them have different sidebars, forget it. The blanks are not THAT hard to get (ok, they indeed are hard to get, but there are some locksmiths that don't care about selling/cutting blanks, look around a bit and eventually, you'll find one).
However, if many sidebars are equal, go for it.

Youll find that most locks are the same for an area, this is because the locla smith doesnt want to carry all the differant sidebar keys so only installs/sells one type, buy a lock and get the keys and you will find that in most cases its the same sidebar as all the others in your area, toool has a data base of all the differant sidebars and which area theve come from but i dont think youll get to see it unfortunatley.

I think that when a locksmith supplies a lock such as the assa twin, lockwood twin or primus style systems, they will be suplied with the side code to use as a constant, which means that they will only supply the one side code.

To me, the whole question of whether you can bump a sidebar lock like this is bogus. When you hear about what people are actually doing - they are cheating! If you don't know the sidebar code - you are basically finished. If you do know the sidebar code you can then go looking for the right "blank" key and prepare it for bumping.

The whole point is: if you know the sidebar code and can get or make a blank to that code, the rest of the exercise is picking or bumping a standard 6 pin lock, though probably still a hard job since ASSA uses anti-pick top pins.
