How does the kit replace factory parts and which part numbers match?

The kit is intended as a mechanical replacement for common factory ignition and door lock cylinder assemblies. It matches common OEM profiles and replaces several frequently used part numbers.

• Replaces ignition and door lock cylinders such as LC6177, DL5885 and 597638 where applicable.
• Includes 1 ignition lock cylinder and 2 chrome-style door lock cylinders for a single-key operation.
• Provides 2 matching OEM-style keys plus 2 oval blanks for cutting or spare use.

Will these keys start my engine, and what about transponder-equipped cars?

The keys supplied are OEM-style mechanical keys intended to operate the lock cylinders mechanically. If your vehicle requires a transponder chip to enable the ignition, the supplied keys will not electronically start the engine.

• For non-transponder vehicles: the kit provides immediate, turn-ready keys after installation.
• If your vehicle uses a transponder key: have one of the supplied keys duplicated as a chip key and programmed by a locksmith or dealer.
• Check your current key for a visible chip head or consult your owner's manual if unsure.

What should I expect from materials, quality, and support?

Goopool builds this kit from durable materials and tests it against common OEM performance benchmarks. The cylinders are metal alloy components with chrome trim on the door locks and keys cut to matching patterns.

• Constructed from premium-quality materials designed for daily use.
• Tested and certified to meet or exceed standard OEM quality expectations.
• Customer support available for replacement if the product has manufacturing issues.

Who is this kit right for? This Goopool lock cylinder kit is ideal for owners of compatible late-'90s to mid-2000s Ford and Lincoln trucks/SUVs who need a direct mechanical replacement for worn, broken, or missing ignition and door lock cylinders. It works well for DIY installers comfortable with basic steering column or door lock disassembly, and for professional mechanics performing a straightforward hardware swap. If your vehicle depends on a factory-programmed transponder, plan to have one of the supplied keys cut and programmed by a locksmith or dealer before relying on it to start the engine.
