Standard Motor Products Door Lock Kits: A Century of OE-Quality Engineering
Standard Motor Products (SMP) has been a trusted name in the automotive aftermarket since 1919, and that century-plus of experience shows in every component they produce — including their lineup of Door Lock Kits. When a door lock cylinder wears out, corrodes, or is damaged in an impact, SMP's door lock kits offer a precision-engineered path back to factory-level security and operation.
Built to OE Specifications — Inside and Out
What sets Standard Motor Products apart in the door lock kit category is their commitment to genuine OE-grade materials. Professional quality construction using solid brass tumblers, chrome plated brass keys, die-cast zinc lock cores and multiple, randomly assigned key codes ensures superior operation. These are not generic blanket-fit parts — each kit is engineered with the tolerances and materials that match the original factory hardware, which matters when it comes to long-term durability and smooth key operation.
Standard® Power Door Lock components are manufactured using the highest-quality components to meet federal safety requirements, and are 100% tested and validated for long-term performance and durability. That 100% testing commitment means every kit that leaves the factory has been validated — a reassurance that matters whether you're a professional technician or a dedicated DIYer.
Wide Vehicle Coverage for Import and Domestic Applications
SMP's door lock kit lineup spans a broad range of applications. Standard® provides unmatched coverage for all import and domestic vehicle applications equipped with gas, hybrid, and electric powertrains. Whether you're restoring a classic Ford Bronco, maintaining a Chevrolet Silverado, or servicing a late-model import, the DL-series product line — which includes part numbers like the DL-1, DL-116L, and DL-224 — is designed to deliver seamless fitment and reliable operation across a wide range of makes, models, and years.
Designed for DIYers and Professional Technicians Alike
Each product is designed and manufactured to OE specifications to ensure they fit like the original and meet Federal Motor Vehicle Safety Standards for door ejection safety, so technicians can install them with confidence. Kits typically include both driver and passenger side lock cylinders, matching keys, and all necessary hardware — making them a complete, hassle-free replacement solution. The kits are designed for easy installation, making them suitable for both DIYers and professionals, though some mechanical knowledge may be beneficial.
