Secure Your Property with Professional Rekey Services

If you’ve recently moved, lost a key, or had a security breach, rekeying your locks is a smart, cost-effective way to maintain control over who has access to your property. At St. Louis Lock & Key, we offer fast, reliable rekey services for residential, commercial, and automotive customers throughout the St. Louis, MO area. Rekeying allows you to change the key that operates your lock without replacing the entire hardware—saving time and money while improving peace of mind.

What is Rekeying?

Rekeying is the process of adjusting the internal components of a lock so it works with a new key. This disables the old keys while maintaining the original lock hardware. It's a perfect solution when you want to increase security without investing in completely new locks.

When Should You Rekey Your Locks?

• After moving into a new home or apartment
• After ending a lease or evicting a tenant
• If you’ve lost your keys or suspect they were stolen
• Following employee turnover at your business
• To create a master key system for improved access control
• After a break-in or attempted intrusion
