How does the kit restore vehicle security and starting reliability?

Worn cylinders cause difficulty turning the key, intermittent starting or doors that won’t lock. Installing new ignition and door lock cylinders returns a crisp key action and consistent electrical engagement for the starter circuit while the matched door cylinders restore uniform locking operation.

• Two door lock cylinders included for driver and passenger doors
• One ignition switch lock cylinder matched to the same key code
• Two keys provided to operate ignition and both door cylinders

What should I know about installation and compatibility before buying?

Installation typically requires basic hand tools and moderate mechanical skill. The kit is a mechanical replacement—verify your vehicle’s year, model and OEM part number against the supplied cross-references before purchase to ensure correct fitment.

• Compare OEM numbers (12300443, 16627130, 26005043, etc.) with your existing cylinders
• Standard installation: remove steering column covers and swap cylinders; door cylinders remove from inside door panel
• If unsure, consult a repair manual or professional installer for model-specific steps

Are the keys keyed alike and what does the kit include?

Yes—the ignition lock cylinder and both door cylinders are supplied keyed alike so one pair of included keys operates all three locks. The package contains the ignition cylinder, two door lock cylinders and two matching keys; no additional tumblers or programming is required.

• Package contents: 1 ignition switch lock cylinder, 2 door lock cylinders, 2 keys
• Keyed alike for immediate use after mechanical installation
• No electronic programming needed for these mechanical locks
