Pakali pano mtundu wa loko pakhomo pamsika uli ndi mawu 67, 17 cross lock, crescent lock 8, magnetic lock 2, osatha kuweruza 6. Apolisi adayambitsa, zokhoma izi malinga ndi mphamvu zotsutsana ndi kuba zimagawidwa kukhala A, B, C atatu. Kalasi A imadziwika kuti ndi loko wakale, yalephera kuletsa akuba, kutsegulira nthawi mphindi imodzi kapena kuchepera. Ndipo B kalasi, C kalasi odana kuba loko loko ndi zovuta kuposa A kalasi odana kuba loko loko mu dongosolo, vuto lotsegula kudzera teknoloji imakulanso kwambiri.

Kalasi A loko: Chotsekera chachikale, kiyi ndi mawonekedwe osalala, alinso ndi mawonekedwe a crescent, kiyi ya concave groove. Mapangidwe amkati a lock core iyi ndi ophweka kwambiri, amangowonjezera kusintha kwa pini, pin groove ndi yochepa komanso yozama. Katetezedwe ka Chitetezo: Chotsekerachi chimatha kutsegulidwa mosavuta ndi mbedza yachitsulo kapena chitsulo. Apolisi anena kuti malokowo akwezedwe ndipo m’malo mwake akhazikitse ntchito yoletsa kuba.

Chotsekera cha Gulu B: mawonekedwe athyathyathya kapena a crescent, fungulo ndi lovuta kwambiri kuposa loko A level, nkhokwe yayikulu ndi imodzi kapena mbali ziwiri zokhala ndi mizere iwiri ya concave, cylindrical multi-point concave keyhole. Kusiyana kodziwikiratu ndi fungulo nkhope zambiri mzere wokhotakhota wosakhazikika mzere wolondera kalozera: pakali pano chitseko cha malo okhala kumene anamanga ndi B kalasi loko zambiri, koma panopa B kalasi loko sikokwanira olimba, kuteteza ake luso kuti tidziwe nthawi 5 Mphindi chabe kapena choncho, kuteteza zotsatira kutsegula nthawi theka la ola kapena kuposa. Chifukwa chake, apolisi akulangiza nzika kuti zikweze.

C loko: ndi pomwe ndi kukweza luso, pali ambiri apamwamba mlingo maloko chitetezo pa msika tsopano, lotchedwa wapamwamba B loko, ndiyeno ena apamwamba, amadziwika kuti C loko mu makampani.

Super B kalasi loko, C kalasi loko: mawonekedwe kiyi ndi lathyathyathya, nkhokwe makiyi ndi limodzi kapena awiri mbali ndi mizere iwiri ya concave ndi S mawonekedwe, kapena mkati ndi kunja kawiri njoka mphero groove groove, ndi ovuta kwambiri ndi otetezeka kwambiri loko pachimake. Zida zitha kutsegulidwa kwa mphindi zopitilira 270, makamaka zotsekera za C-level, zomwe sizingatsegulidwe konse ndiukadaulo.
