How It Works

This ignition lock cylinder is built for vehicles that use onboard programming, allowing the replacement keys to be programmed without a dealership visit in many cases. It is a practical solution for GM trucks, SUVs, and vans such as the Chevrolet Silverado, GMC Sierra, and Cadillac Escalade when the original lock cylinder is worn, sticking, or no longer turning smoothly. This part cross-references 15794826 and LC65454 for the same application.

Common Problems It Can Solve

• Key will not turn or binds in the ignition
• Worn lock cylinder causing inconsistent ignition operation
• Lost or damaged transponder key replacement needs
• Need for a replacement ignition lock cylinder after wear or theft-related damage
• Reduced convenience from dealership-only programming requirements

Installation Notes

Verify vehicle fitment by year, make, model, and onboard programming requirement before installation. Programming steps vary by application, so follow the vehicle-specific procedure after the lock cylinder is installed. Mounting hardware and wiring harness are not included.

Quality Assurance

Dorman OE FIX components are engineered as direct replacement solutions for common factory service issues. Part number 924-796 uses metal construction and includes programmable keys to simplify the replacement process on supported GM applications.
