Vault doors are the cornerstone of banking security, protecting millions of dollars in assets and sensitive materials. Like any precision mechanical system, they require regular maintenance to ensure optimal performance, security, and compliance with banking regulations.

At Exum Services Inc., we've maintained vault doors for over 25 years, and we've learned that preventive maintenance is far more cost-effective than emergency repairs. This comprehensive guide outlines the essential maintenance procedures that will keep your vault door operating safely and efficiently for decades to come.

Daily Visual Inspections

Door Alignment Check

Ensure the vault door closes properly and aligns correctly with the frame. Look for any gaps or misalignment that could indicate hinge wear or structural issues.

Locking Mechanism Operation

Test the smooth operation of the locking wheel and verify that all locking bolts extend and retract fully. Listen for unusual sounds that might indicate mechanical problems.

Visual Damage Assessment

Inspect the door surface, frame, and surrounding area for any signs of attempted tampering, scratches, dents, or other physical damage that could compromise security.

Weekly Maintenance Procedures

Lubrication of Moving Parts

Apply appropriate lubricants to hinges, locking bolts, and the combination mechanism. Use only manufacturer-approved lubricants to prevent damage to precision components.

Combination Lock Testing

Test the combination lock multiple times to ensure consistent operation. Verify that the lock opens only with the correct combination and that there are no signs of wear in the dial mechanism.

Time Lock Verification

If equipped with a time lock, verify proper operation and ensure the time settings are accurate. Check battery levels and replace if necessary.

Monthly Professional Inspections

Comprehensive Security Assessment

Conduct a thorough security evaluation including testing of all locking mechanisms, alarm systems, and access controls. Document any irregularities or potential vulnerabilities.

Structural Integrity Check

Examine the vault door frame, mounting bolts, and surrounding structure for any signs of stress, corrosion, or deterioration that could affect security or operation.

Electronic Systems Testing

Test all electronic components including sensors, alarms, and monitoring systems. Verify proper communication with central security systems and backup power supplies.

Annual Professional Service

Complete Mechanism Overhaul

Professional disassembly, cleaning, and reassembly of the locking mechanism. Replace worn components and recalibrate all systems to manufacturer specifications.

Compliance Certification

Ensure the vault door meets all current banking regulations and security standards. Update certifications and documentation as required by regulatory bodies.

Review and update emergency access procedures, test emergency opening mechanisms, and ensure all staff are trained on proper protocols.
