Ignition Switch Lock Cylinder Compatible with Ford E150 E250 E350

In this review the focus is on a replacement ignition switch and door lock cylinder kit intended for older Ford trucks and SUVs. The kit delivers a straightforward mechanical solution for owners needing a matched set of locks: one new ignition lock cylinder, two front door lock cylinders and two matching Ford OEM keys. The single biggest reason to buy is the complete lock set that directly replaces LC6177, DL5886 and 597638 numbers, making it a time-saving swap when restoring ignition and door security on compatible 1996-2008 models.

Key Features

• Compatibility: Covers a wide range of Ford models so buyers can replace ignition and door cylinders for multiple years without searching for separate parts.
• Complete kit: Includes one ignition cylinder, two front door cylinders and two matching OEM keys to provide a matched set that simplifies installation and key management.
• OEM match: Replaces LC6177, DL5886 and 597638 numbers which helps ensure fitment aligns with original equipment expectations for listed vehicles.
• Material quality: Constructed from premium materials and tested to meet or exceed OEM quality standards, which supports long-term mechanical reliability.
• Installation friendly: Users report the components are easy to install, reducing labor time for DIYers or technicians working on older Ford models.
• Support: The seller invites direct communication for pre- and post-sale questions, offering a clear channel for assistance.

Who It's For

This kit is aimed at owners and independent mechanics working on Ford Aerostar, Explorer, Explorer Sport Trac, E150, E250, E350, Ranger and Mercury Mountaineer models from the late 1990s through the 2000s who need a matched set of ignition and front door lock cylinders. It is especially useful when replacing worn or damaged lock cylinders and when a matched pair of keys is required to rekey multiple locks at once.

It is not suitable for vehicles that require a transponder (chip) key to start the engine unless the buyer plans to have the supplied key duplicated and the transponder programmed separately by a locksmith or dealer. Buyers who need a transponder-ready solution should look for a kit that explicitly includes a chip key.

Pros & Cons

Pros

• Complete matched set with ignition and two front door lock cylinders plus two keys removes the hassle of sourcing parts separately.
• Good fit and OEM-level matching for the specified Ford and Mercury models means fewer modifications during installation.
• Customers report easy installation and strong value for money compared with buying individual cylinders.

Cons

• Does not include a transponder chip key, so it will not start vehicles requiring a programmed chip without additional locksmith or dealer work.

Specifications

Our Verdict

This lock cylinder kit is a practical, cost-effective choice for anyone repairing or restoring ignition and front door locks on compatible Ford and Mercury vehicles. It provides a matched set that fits OEM specifications and is easy to install, but buyers must be aware that the keys are non-transponder and will require separate programming if their vehicle needs a chip. For mechanical replacements where transponder programming is not required, it delivers solid value.
