Mul-T-Lock Lubricant for Post 2010 Cylinders, 5oz

5oz Mechanical & electro-mechanical cylinder & lock lubricant spray. The cylinder lubricant spray is a lubricant which is safe to use on both mechanical and electro-mechanical cylinders. It contains Teflon as a major ingredient which ensures the key tumbler lasts for a very long time.

This professional-grade lubricant is designed to meet the rigorous maintenance requirements of Mul-T-Lock cylinders manufactured after 2010. Featuring a Teflon-infused formula, it creates a long-lasting protective barrier that reduces friction and prevents internal components from sticking or jamming. Whether for residential deadbolts or complex commercial master key systems, regular application keeps your security hardware functioning like new.

Key Features

  • Post-2010 Specialized Formula: Engineered specifically for modern CLIQ® (plugs marked with "O") and mechanical cylinders.

  • Teflon™ Enhanced Durability: Contains Teflon as a primary ingredient to significantly extend the lifespan of the key tumbler mechanism.

  • Dual System Compatibility: Safe and effective for use on both mechanical and electro-mechanical (CLIQ®) cylinders without damaging sensitive electronic components.

  • Weather Resistance: Provides consistent performance in demanding environments, protecting against rust, corrosion, and moisture.

  • Precise Application: Equipped with an easy-to-use spray nozzle and applicator straw for targeted lubrication of narrow keyways.

Functions & Benefits

  • Reduces Wear and Tear: Minimizes friction between the telescopic pins and the key, preventing premature mechanical failure.

  • Cleans and Protects: Penetrates to eliminate dirt, dust, and grime while leaving behind a protective sealing film.

  • Seamless Operation: Eliminates key sticking and difficulty in turning, ensuring a seamless user experience every time.

  • Preventive Maintenance: Helps maintain warranty compliance; Mul-T-Lock recommends lubricating exterior cylinders at least four times per year for optimal performance.

Mul-T-Lock MULLST-LUBE-MU – Frequently Asked Questions

1) Is this Mul-T-Lock lubricant safe on CLIQ electronic cylinders?
Yes. The Mul-T-Lock 5 oz cylinder lubricant spray is formulated for both mechanical and electro-mechanical CLIQ cylinders, so it won't harm the electronic components inside a CLIQ plug. If you're running a mix of mechanical and CLIQ cylinders on a site, one can covers both.
2) How do I know if my Mul-T-Lock cylinders are the post-2010 type this lubricant is meant for?
Mul-T-Lock's post-2010 cylinders are the ones this spray is built for, and on the CLIQ side they're identified by an "O" mark on the plug. Post-2010 mechanical cylinders are covered too. If you're maintaining older pre-2010 Mul-T-Lock stock, this is not the formula matched to them.
3) Can I get this lubricant into a narrow Mul-T-Lock keyway without pulling the cylinder?
The can ships with a spray nozzle and an applicator straw, so you can shoot it straight down a narrow keyway on a mounted cylinder. No need to pull the lock or disassemble anything for routine service.
4) How often should exterior Mul-T-Lock cylinders be lubricated?
Mul-T-Lock's own recommendation is at least four times a year on exterior cylinders. For a property manager or MRO buyer that's a quarterly line on the PM schedule; one 5 oz can services a lot of openings per round, so it's a reasonable per-building stock item.
5) Why use a Teflon cylinder spray instead of a general purpose penetrating oil on a high security lock?
This Mul-T-Lock spray uses Teflon as a primary ingredient, which leaves a dry protective film rather than a wet oil that collects dust and grime in the keyway. It cleans out dirt as it penetrates and cuts friction between the key and the telescopic pins in a Mul-T-Lock plug, which is exactly where a gummy oil causes sticking on these cylinders.
6) Will this fix a Mul-T-Lock key that sticks or turns hard?
A key that binds or turns stiff in a Mul-T-Lock plug is usually friction and contamination in the pin stack, and that's what this spray addresses: it flushes dirt out of the keyway and lubricates the telescopic pins so the key stops catching. It won't fix a mechanical fault such as a bent key, a damaged plug or a misaligned strike.
7) Will this hold up on exterior door cylinders exposed to weather?
Yes. The spray leaves a sealing film that protects against rust, corrosion and moisture, which is why the four-times-a-year service interval is specified for exterior cylinders in particular. Gate, perimeter and storefront cylinders are the ones that benefit most.
8) What part number do I order for the Mul-T-Lock 5oz cylinder lubricant?
Mul-T-Lock part number 51100 is the 5 oz (142g) aerosol cylinder and lock lubricant. There's a single configuration, so there is nothing else to specify when ordering.
