The kit ships with everything needed to replace the ignition and door lock cylinders, and it’s designed to match original mounting and keying for a near plug-and-play swap. Basic hand tools are typically sufficient for do-it-yourself installation, though professional installation is available if you prefer.

• Installation usually requires removal of the steering column cover and door panels; no programming required

What should I expect in terms of fit, keying, and durability?

The cylinders are manufactured to match factory specifications for secure fit and consistent key operation. Keys are provided already matched to the cylinders, so you’ll have immediate, single-key access to ignition and doors.

• Single-key setup reduces the need for rekeying multiple locks
• Metal construction designed for vehicle-grade wear resistance
• Cross-referenced with multiple OEM numbers for confident compatibility

Are there any pre-purchase checks or limitations I should know about?

Confirm the part numbers and the vehicle model years against the compatibility list to ensure a match; some late-model variants or vehicles with aftermarket security systems may require additional steps. This product replaces mechanical lock cylinders and does not include electronic immobilizer programming.

• Not an electronic immobilizer module—no ECU programming is included
• Verify steering column and door hardware condition to avoid installation issues
• Compare your original part number(s) with listed replacement numbers before ordering
