Mul-T-Lock’s 3‑in‑1 cylin­der allows instant mechan­i­cal lock cylin­der re-key­ing with­out need­ing spe­cial tools or ser­vices.

No dis­as­sem­bly or removal of the cylin­der is required. Insert and turn a colour-cod­ed key to per­ma­nent­ly change the cylin­der to a new com­bi­na­tion and nul­li­fy the pre­vi­ous key up to two times. This cylin­der allows you to change a lock com­bi­na­tion all on your own. Lost keys or cir­cum­stances requir­ing a user to change a lock com­bi­na­tion imme­di­ate­ly are quick­ly resolved by 3 in 1 cylin­der. 3 in 1 Cylin­der Ben­e­fits:

Why should you, as a consumer, choose PROTECTION PLUS and Mul-T-Lock Toronto

  • Over 40 years of expe­ri­ence, cut­ting-edge tech­nol­o­gy and 100’s patents on lock/key tech­nol­o­gy to keep you safe and free from unau­tho­rized dupli­ca­tion.
  • They patent­ed Key con­trol sys­tems. With strict fac­to­ry key con­trol reg­u­la­tions, Mul-T-Lock­’s Key Con­trol Sys­tems are engi­neered to pre­vent unau­tho­rized key dupli­ca­tion. Dupli­ca­tion of Mul-T-Lock keys is only pos­si­ble at autho­rized ser­vice cen­tres on Mul-T-Lock key cut­ting machines.
  • Tam­per resis­tance. Mul-T-Lock prod­ucts are designed to with­stand many forced entry attempts, from pick­ing, bump­ing or drilling. Mul-T-Lock­’s unique tele­scop­ic pin tum­bler mech­a­nism will defeat even the most expe­ri­enced lock pick­er. Ten and eight-pin cylin­der designs enhance the lev­el of secu­ri­ty by requir­ing a dual shear line match for the cylin­der to oper­ate. Plus, each cylin­der incor­po­rates hard­ened steel inserts in strate­gic areas to offer a high lev­el of drill resis­tance. Also, advanced pro­tec­tive ele­ments such as mush­room and split plug pins, inter­lock­ing tele­scop­ic pins and strict key con­trol pro­ce­dures elim­i­nate the threat of bump­ing.
  • Sin­gle key mul­ti­ple-use solu­tions. While Mul-T-Lock pro­duces many types of keys and locks for com­plex sit­u­a­tions, they also offer one key solu­tions to make your life eas­i­er. With one Mas­ter Key, open your fil­ing cab­i­net, serv­er room, tool shed and office door with one Key on your ring.
  • Ver­sa­til­i­ty. No job is too large or small for Mul-T-Lock. The vast prod­uct line extends to both for­eign and domes­tic locks, pad­locks, and cylin­ders. High-secu­ri­ty lock­ing solu­tions for Cana­di­an, Amer­i­can, Scan­di­na­vian, Japan­ese, and French lock­sets, which can be incor­po­rat­ed into a sin­gle key­ing sys­tem, are just part of Mul-T-Lock­’s impres­sive prod­uct port­fo­lio.
