Mul-T-Lock services we offer
Our Mul-T-Lock services in Whittier CA include both lock change and rekey options depending on your security needs and the condition of your current hardware.
Mul-T-Lock lock change: Replacing standard locks or outdated hardware with Mul-T-Lock high-security systems. This is recommended when upgrading to a restricted key system or improving protection against forced entry.
Mul-T-Lock lock rekey: Adjusting the internal cylinder so old keys no longer work while maintaining the same hardware. This is ideal for properties that already use Mul-T-Lock systems but need updated access control.
Cylinder upgrades: Installing Mul-T-Lock cylinders into compatible locks to enhance security without replacing the entire mechanism.
Master key systems: Configuring multiple locks to operate under a controlled key hierarchy, often used in offices and multi-unit properties.
We also provide related services such as lock replacement, lock rekey, and deadbolt upgrades when integrating Mul-T-Lock solutions into your property.
Rekey vs lock change
Rekeying is often the best option when your existing Mul-T-Lock hardware is still in good condition and you simply need to change who has access. It allows you to maintain your high-security system while issuing new authorized keys.
Lock replacement is recommended when upgrading from standard locks to Mul-T-Lock systems or when existing hardware is worn or outdated. Many customers choose full replacement to take advantage of advanced features such as patented key control and enhanced resistance to forced entry.
