Mul-T-Lock’s 3 in 1 cylinder

At PROTECTION PLUS®, we have pro­tect­ed our com­mer­cial cus­tomers for over 25 years, offer­ing the lat­est advance­ments in cus­tomized busi­ness secu­ri­ty sys­tems. We pride our­selves in find­ing afford­able solu­tions, so every busi­ness has options that keep com­mer­cial prop­er­ties, assets, and staff safe. The Mul-T-Lock’s 3‑in‑1 Cylin­der address­es the com­mon chal­lenge pre­sent­ed by lost or stolen busi­ness keys. Cost­ly lock replace­ment is no longer required with this all-in-one lock. With a three-key sys­tem you auto­mat­i­cal­ly change the lock con­fig­u­ra­tion using a new key when your mas­ter key is lost or stolen. What could be sim­pler than a key sys­tem you have com­plete con­trol over 24/7?

Why Consider the Mul-T-Lock’s 3‑in‑1 Cylinder?

The Mul-T-Lock’s 3‑in‑1 cylin­der allows instant mechan­i­cal lock cylin­der rekey­ing with­out spe­cial tools or ser­vices. The colour-cod­ed keys include the green key, the ini­tial mas­ter key you choose to hold or share with a trust­ed team mem­ber.

Should that key be lost or stolen, the yel­low key is insert­ed into the lock to rekey the cylin­der auto­mat­i­cal­ly. The final red key is used when the yel­low key is lost. If the third key is com­pro­mised, a PROTECTION PLUS® lock­smith will reset the cylin­der and pro­vide a new set of keys the same day. 3‑in‑1 Cylin­ders offer many ben­e­fits, includ­ing:

  • More Con­trol: You have com­plete con­trol over your lock sys­tem and can alter a cylin­der instant­ly whether the key is lost or you have made an unex­pect­ed staff change that calls for quick access changes.
  • DIY Rekey­ing: You make the changes your­self in sec­onds with­out wait­ing for a lock­smith in an emer­gency sit­u­a­tion.
  • Afford­able: There are no rekey­ing labour costs or expen­sive key replace­ments.
  • Val­ue: Autho­rized Mul-T-Lock deal­ers can eas­i­ly reset 3‑in‑1 key­ing once all keys are com­pro­mised.
  • Sim­plic­i­ty: It is the most user-friend­ly lock sys­tem avail­able, with a ful­ly mechan­i­cal func­tion that does not require com­plex soft­ware or expen­sive elec­tron­ics.

Our PROTECTION PLUS® lock­smiths are autho­rized Mul-T-Lock experts ready to install your new cylin­der as an afford­able, easy solu­tion to keep your busi­ness secure.

How Does the Mul-T-Lock’s 3‑in‑1 Cylinder Work?

Your Mul-T-Lock 3‑in‑1 Cylin­der requires no dis­as­sem­bly or removal of the cylin­der when a key is com­pro­mised. You insert and turn the next colour-cod­ed key to change the cylin­der to a new com­bi­na­tion. Once the next key is used, the pri­ma­ry key is nul­li­fied so that the per­son hold­ing the key can­not enter the premis­es.

The Mul-T-Lock cylin­der allows you to change the lock com­bi­na­tion any­time with­out need­ing a lock­smith. It uses a patent­ed tele­scop­ic pin tum­bler mech­a­nism with inter­nal and exter­nal pins that both need to align at the same time to work. This allows the lock­’s plugs to rotate and reach the right posi­tion to lock and unlock the door.

Regard­less of why your lock must be changed, you can do it imme­di­ate­ly. Once the final key is com­pro­mised, a quick call to our autho­rized, cer­ti­fied lock­smiths will have the main cylin­der replaced and a new set of keys in your hands the same day.
