- ANSI/BHMA Grade 1 certified for top-tier performance

If you're serious about security, Mul-T-Lock offers industry-leading protection, especially when installed and maintained by professionals like Lock Change Austin.
Mul-T-Lock Rekey
Rekeying a Mul-T-Lock system is significantly more secure and controlled than standard rekeying. Only authorized locksmiths with proper equipment and credentials can rekey or duplicate Mul-T-Lock keys.
Whether you're taking over a new commercial lease, recovering from a lost key, or managing multiple users, our mobile locksmiths carry genuine Mul-T-Lock parts and cylinders to rekey your system on-site — with full documentation and new keys issued under registered codes.
Estimated cost: $45–$75 per lock. Includes security verification, disassembly, re-pinning with authorized parts, and key issuance. Restricted key duplication is offered with proper ID.
Smart Locks
Mul-T-Lock integrates mechanical excellence with smart functionality using the ENTR™ and CLIQ® systems. These locks bring keyless entry, programmable access, and real-time monitoring to one of the strongest physical platforms on the market.
Standard Smart Locks: Mul-T-Lock’s ENTR™ and CLIQ® allow mobile access via smartphone, fingerprint, or PIN, and are designed to replace existing cylinders without drilling.
Retrofit Smart Locks: ENTR™ systems allow you to keep your Mul-T-Lock hardware while upgrading the cylinder with a smart, motorized solution — ideal for apartments, offices, or medical facilities.
Smart Mul-T-Lock solutions give you full control over who enters, when, and how — all without compromising the brand’s legendary physical security.
Do It Yourself VS Using Professional Locksmith
DIY installation of Mul-T-Lock products is strongly discouraged. These high-security locks are complex, require precision installation, and often come with legal and technical restrictions on access and service.
DIY Pros: Limited, mostly cost savings — but typically voids warranties and leads to service calls.
DIY Cons: Improper installation may weaken security. Restricted key systems require locksmith access to rekey, duplicate, or reset credentials.
Professional Pros: Certified service, authorized key registration, clean installation, and full warranty on work and parts.
Professional Cons: Higher upfront cost — but ensures long-term integrity and legal key control.
