APPERFiT Door & Ignition Lock Cylinder Kit for 2001–2007 Chevy/GMC (2 Door + 1 Ignition) OEM-fit, Includes 2 Keys

APPERFiT door lock cylinders plus an ignition switch cylinder with matching keys provide a direct-fit replacement for worn or broken locks on many 2001–2007 GM trucks and SUVs.

If the factory door locks or ignition cylinder on your Chevrolet, GMC, Cadillac or Hummer are sticking, tumblers are worn, or keys snap, this kit gives you a complete replacement set that restores secure access and reliable starting. The parts are manufactured to match OEM dimensions and function so installation is straightforward for a technician or experienced DIYer. The package includes two exterior door lock cylinders, one ignition switch lock cylinder and two cut keys, and comes with a one-year warranty for added confidence.

What vehicles and years will these lock cylinders fit?

This kit is engineered for classic GM platforms from the early 2000s. It fits a broad range of trucks and SUVs that share the same lock cylinder specifications, including pickups and full-size passenger vehicles.

• Chevrolet Silverado 1500/2500/3500 Classic (2001–2007)
• Chevrolet Avalanche (2002–2006), Suburban and Tahoe (2001–2006)
• GMC Sierra 1500/2500/3500 Classic (2001–2007), Yukon (2001–2006)
• Cadillac Escalade (2002–2006) and Hummer H2 (2003–2007)

How closely do these parts match the original equipment?

APPERFiT lock cylinders are produced to align with factory dimensions and specifications so they operate like the originals. That means the cylinder housings, key profiles and actuator interfaces are designed for plug-and-play replacement without extensive modification.

• Designed as direct-replacement for OEM part numbers: 15298924, 88937321, 706592, and others
• Correct fit for front driver and passenger exterior door handles plus steering column ignition location
• Sold as a kit: two door cylinders, one ignition cylinder, and two keys for immediate use

What should I expect during installation and usage?

Installation typically follows the same removal and swap steps as the original components; many owners replace the cylinders without replacing the entire handle or column assembly. The new cylinders should turn smoothly and accept the supplied keys without binding once properly seated.

• Common tools needed: basic hand tools and possibly a trim removal tool
• Installation locations: front left driver and right passenger door handles; steering column ignition
• Ships new, ready to install, and backed by a one-year warranty

Will these replacement locks improve security and reliability?

Replacing worn or damaged cylinders restores the mechanical security and reduces the chance of key breakage or ignition failure. While they aren't an electronic anti-theft upgrade, fresh mechanical cylinders reduce jams and misalignment that can lead to lockouts or ignition problems.

• New tumblers reduce key slip and sticking
• Properly fitted cylinders lower the risk of accidental key damage
• Kit includes two identical keys for driver convenience

Who this is for: This APPERFiT kit is aimed at owners of early-2000s GM trucks and SUVs who need a reliable mechanical replacement for worn exterior door locks and a failing ignition cylinder. It's suitable for DIY mechanics comfortable with basic disassembly, professional installers who require OEM-compatible parts, and fleet managers maintaining multiple vehicles from the specified model years. If you need direct-fit components, two keys included, and a one-year warranty, this kit covers those needs without replacing larger assemblies.
