How precise is the fit and do I need special tools to install?

APPERFiT lock cylinders are manufactured to match OEM form and function, so installation is straightforward for anyone familiar with basic door and steering column work. No vehicle-specific programming is required because these are non-transponder mechanical cylinders.

• Exact-match dimensions for drop-in replacement in factory housings
• Keyed-alike set avoids swapping multiple keys
• Standard hand tools (screwdrivers, pliers) are typically sufficient
• Instructions or online guides from APPERFiT can assist first-time installers

What’s included and what condition are the parts in?
