Their patented key systems prevent unauthorized duplication, and their cylinders feature advanced anti-pick, anti-bump, and anti-drill protection. For anyone serious about physical security, Mul-T-Lock is a top recommendation.
Mul-T-Lock’s modular lock designs make upgrades easy, and their solutions scale from individual doors to large master-key systems. Their hardware is ANSI Grade 1 certified and tested to withstand extreme wear and force. In Katy, we often install Mul-T-Lock in high-risk areas or properties needing restricted key duplication and enhanced access control.
While more expensive than standard locks, Mul-T-Lock offers long-term value in durability, key control, and resistance to common break-in techniques. If you're concerned about safety, these locks offer confidence and peace of mind.
Mul-T-Lock Rekey
Rekeying a Mul-T-Lock system requires specialized equipment and the correct authorization level for key duplication. If you're a property owner or manager who needs to change access due to lost keys or tenant turnover, our locksmiths can rekey Mul-T-Lock cylinders quickly and securely.
We handle rekeying for Interactive+, MT5+, and Classic platforms. Prices typically range from $75 to $110 depending on the lock type and if new keys are required. Each rekey includes testing, relabeling keyways, and ensuring compatibility with your existing system or master key plan.
Smart Locks
Mul-T-Lock's smart lock line includes the ENTR and SMARTair systems, combining strong mechanical security with digital access. These locks support remote management, app-based unlocking, RFID cards, PIN codes, and biometric access, depending on configuration.
Standard Mul-T-Lock smart locks replace your existing deadbolt with a fully motorized, encrypted lock connected via Bluetooth or Wi-Fi. Retrofit kits like ENTR can upgrade your mechanical lock to smart functionality without changing the keyway.
In Katy, we install Mul-T-Lock smart systems in homes, rental properties, and commercial offices requiring advanced access tracking and keyless control. We configure the system, handle app pairing, and walk you through daily use.
Do It Yourself VS Using Professional Locksmith
Mul-T-Lock installations are not recommended for DIY. The precision involved in aligning high-security cylinders and the need for key code authorization requires professional tools and training. Improper setup can damage the lock or void its security features.
