Compliance Parts LMC5 Module for C5 Corvette — Black steering column lock bypass, solid-state reliability

The Compliance Parts LMC5 is a compact, solid-state module that simulates a healthy steering column lock to prevent or repair C5 Corvette lock-related drive interruptions.

If your 1997–2004 C5 Corvette shows "Pull Key," "Wait 10 Seconds," or "Service Column Lock" messages, or if it experiences the 2 mph fuel cutoff, the fault often originates with the column lock system. Many C5s were affected by recall-related issues that left the physical lock disabled or vulnerable to electronic failure. The LMC5 installs in the passenger footwell, avoids permanent modifications, and works with existing recall devices—providing a non-mechanical, no-moving-parts solution intended to restore normal electrical signaling from the column lock circuit.

How does the LMC5 stop my Corvette from losing drive power at low speed?

The LMC5 emulates the expected electrical behavior of a properly operating column lock, removing the false "locked" or "service" states that can trigger safety cutoffs. Because it's a solid-state unit, there are no mechanical linkages to wear or bind.

• Recreates the correct lock/unlock signal to the car's electronics
• Prevents the 2 mph fuel cutoff caused by false lock signals
• Operates without moving parts for long-term stability
• Installs without altering recall repairs or factory wiring permanently

Will this work if my steering wheel is already stuck locked?

If the column is physically jammed, you should select a kit that includes the Unlocker. The Unlocker is designed to free stuck columns and is available bundled with the LMC5. Tech support can guide you through using the Unlocker if needed.

• LMC5 alone: for wheels that turn freely
• LMC5 + Unlocker: frees and protects stuck columns
• LMC5 + Unlocker + Tool Kit: includes 1/4" and 5/16" wrenches for convenience
• Expert phone support available for unlocking assistance

How difficult is installation, and will it void my recall repairs?

Installation is designed to be straightforward and non-destructive: the module mounts in the passenger footwell and ties into the column lock circuit without cutting or permanently altering factory components. It does not interfere with recall hardware or procedures.

• No permanent modifications to the column or wiring
• Mounts easily under the passenger-side dash area
• Works alongside existing recall-mounted devices
• Free US-based phone tech support to walk you through steps

What kinds of failures does the solid-state design address?

The LMC5 tackles the common electronic failure modes that cause the vehicle to believe the column is locked when it is not, as well as failures that cause intermittent lock signaling. Because there are no moving parts, it removes mechanical failure points that lead to disabling errors.

• Corrects intermittent or false lock signals to the ECU
• Reduces risk of repeat disabling events from column lock faults
• Prevents electronic behaviors that trigger limp-mode protections
• Durable solid-state construction minimizes future malfunction

Who this product is for: The LMC5 is aimed at C5 Corvette owners (1997–2004) who have experienced or want to prevent column lock-related drivability interruptions—especially those encountering "Pull Key," "Wait 10 Seconds," "Service Column Lock," or the 2 mph fuel cutoff. Choose the single module if your steering wheel turns freely; pick a combo with the Unlocker if the column is physically jammed; add the Tool Kit if you prefer to have the needed wrenches included. Technical phone support is provided from the U.S. to assist with diagnosis, unlocking and installation.
