This brand has done a very good job of getting their name out there. Mul-T-Lock is easily recognizable as the company with the key that is morphing into a strong man. Many people trust the strength they perceive from the silhouette’s bicep flex. Their reputation proceeds them. The locks themselves are very secure. Often keys are integrated with an active element that takes a bit more knowledge and experience to pick. They are of course pickable, but they present a challenge. Good cores and solid construction will only get you so far. If you are purchasing a euro profile cylinder from this company, know that you should not install a thumbturn. With a thumbturn on this type of cylinder, the core can be easily bypassed. Even with all of that said, it is a great brand with a trusted reputation.
