How to Remove a Cam Lock

As a ISO-certified cam lock manufacturer with 30+ years of expertise, Mingyi Hardware provides industry-approved removal techniques to ensure zero damage to panels or lock mechanisms.

Tools Required

Precision Screwdriver Set (Phillips/Flathead)

Needle-Nose Pliers (Mingyi recommends 6" anti-slip grip)

Lubricant (Silicone-based, compatible with ASTM D4950)

Lock Removal Kit (Optional for seized locks - View Our Professional Tools)

6-Step Removal Procedure

Step 1: Access the Lock Interior

For Cabinets: Open door/drawer to expose lock backside

For Enclosures: Remove adjacent panels if necessary

Safety Tip: Wear ANSI Z87.1 safety glasses against metal fragments

Step 2: Locate Retention Clip

Identify C-shaped clip on lock barrel (standard cam locks)

Mingyi Design Note: Our locks feature blue-coated clips for visibility

Step 3: Remove Retention Clip

Use needle-nose pliers to gently expand clip (0.5-1mm gap)

Technical Caution: Avoid over-bending beyond material yield point (Zamak 3: 220 MPa)

Step 4: Extract Lock Body

Push lock outward from rear while stabilizing front bezel

Stuck Lock Solution: Apply Mingyi MX-200 Penetrating Oil (3 drops, wait 2 mins)

Step 5: Disassemble Components

Unscrew face plate (typically 2-4 screws)

Separate cam from actuator shaft (note orientation marks)

Critical Documentation: Photograph assembly for reinstallation reference

Step 6: Clean & Inspect

Check for:

Worn spring (replace if stretched >15% original length)

Corroded cam plate (salt residue indicates need for 316SS upgrade)

Damaged key pins (Mingyi offers cylinder rebuild kits)

3 Complex Removal Scenarios

Case 1: Broken Key in Cylinder

Use Mingyi Key Extractor Tool (0.8mm hook)

Insert parallel to key blade, rotate 45° clockwise

Alternative: Order replacement cores with QR code tracking

Case 2: Stripped Screws

Technique:

Apply liquid nitrogen (-196°C) to contract metal

Use left-hand drill bit (5/64") at 200 RPM

Preventative Measure: Our TorqShield screws resist stripping

Case 3: Welded Cam Plate

Solution:

Cut along weld line with 0.6mm diamond saw blade

Polish surface to Ra 3.2μm smoothness

Upgrade Tip: Switch to Mingyi's quick-release cam system
