what is this lock

[Karosa]

okay.. so still very common in hungary is an old type of lock manufactured by elzett, If I'm correct there are 99 different pre-made keys for these (so if I'd need replacement keys for a lock I'd just go into a store that has em and say gimme four of the 18th key) at least I think so.. What's sure is that keys with the same number are alike and open the same locks.. my three questions are.. what are these locks actually called? and.. what's the best way to pick them? and with which tools? Couldn't find a lock to take pictures of yet, but anyway here's the key #18.

okay photobucket lost my album in a raid crash, and I don't think i'll be reuploading the pics, coz I got my questions anwsered, thanks ppl

those locks are lever locks with a single lever and a warded keyway, any instrument fitting the mask of the keyway will open the lock

Those locks are frequently used in Germany as well - as doors for rooms inside a flat or house. Locking yourself in with those locks usually means "Leave me alone for a while" as there is no security with those locks.

These are very basic warded locks, they open easily with a button hook, which is a wire with a backward C on the end, or with just 2 L shaped wires.

The german name is Buntbartschloss and I usually need only one L shaped wire to open them (thick wire). English name is warded lock I think.

wire does indeed work. My favoured method however is to use an original key, file it so flat metal tag, as thin as possible, with no detail left on it. Then just use that as a "key". Providing it fits INTO the keyway, and is long enough to move the bolt over, it will work.

I carry 3-4 variations which between them open every warded and 2 lever lock I have come across. Saves a lot of time and wire coat hangers!
