Tallanpick video shows 11-pin AGA cylinder picked and disassembled

An 11-pin AGA cylinder is the kind of lock that changes the conversation before the gutting even begins. Tallan Pick’s video did not stop at opening the SERTECSA-marked cylinder, it went on to disassembly, which is where the real lesson for locksport lives.

The title alone signaled a tougher piece of hardware than the starter locks many pickers cut their teeth on. In pin-tumbler terms, that matters because movable pins are what hold the plug from turning until the correct key lifts them to the shear line. With 11 pins in play, every tolerance stacks on top of the last one, and the difference between a clean open and a frustrating bind can come down to tiny variations in spring pressure, pin length, and core behavior.

That is why the teardown is more valuable than the open itself. Once a cylinder is gutted, the structure becomes visible: the pin stack layout, the spring behavior, the driver and key pin lengths, and any features the maker used to complicate the action of the plug and actuator. The video’s picked-and-disassembled framing suggests exactly that kind of inspection, not just proof of skill but a look at why the lock fought in the first place.

The companion upload appeared on Tallan Pick’s YouTube channel, which describes itself as a sport-lockpicking channel and says it shows examples of sporting lock picking, tips, and tricks. That fits the wider LockLab archive, where Spanish-language picks often arrive with English subtitles and a teardown format that travels well across the international scene. In a hobby that thrives on shared footage, translated captions and community archives matter as much as the locks themselves.

The hardware lineage is part of the appeal, too. TESA, short for Talleres Escoriaza SA, was founded in 1941 in Spain and is now part of ASSA ABLOY. That places the cylinder in a familiar European manufacturer family, but the 11-pin layout still marks it as serious practice for anyone used to smaller pin counts. Lockwiki describes pin-tumbler locks as one of the most widely used lock designs in the world, and defines a cylinder as the part that holds the plug, actuator, and locking components, which is exactly why a gutted example teaches so much.

The clip’s real value is that it turns a successful open into a mechanical readout. An 11-pin AGA cylinder is already a demanding test; once it is picked and stripped down, the challenge stops being whether it opened and becomes a clearer question of how it was built to resist.
