What the ASP Collection Offers

The ASP collection at Keyless City is your go-to source for automotive lock cylinders, ignition parts, tumbler packs, springs, and replacement hardware. Whether you're servicing Ford, GM, Toyota, Honda, or Chrysler, you'll find coded and uncoded cylinders for doors, trunks, ignitions, plus replacement tumblers and springs. Built for professionals, these ASP parts fit seamlessly into standard OEM systems - giving you reliable, precision replacement components without sacrificing compatibility or quality.

Coded and Uncoded Lock Cylinders

From classic rides to modern rigs, we carry both coded (pre-keyed) and uncoded cylinders so you can match existing keys or cut new ones. Highlights include the 1975–1991 Ford H51 Ignition Lock Cylinder (ASP-C-42-406), coded for vintage restoration, and the 2001–2019 Ford H75 Ignition Lock Cylinder (uncoded, ASP-C-42-197), ideal for fresh installs. Both offer OEM-grade fit for smooth operation and longevity.

Tumbler Packs and Springs

Need tumbler sets for rekeying or repair? We stock ASP tumblers like the Toyota X174 / TR40 / MIT1 Tumbler #2, #3, #4 (25 packs), perfect for Toyota and Lexus cylinder jobs. You'll also find Universal Brass Springs (P-31-100) and Universal Lock & Ignition Springs (P-00-100) to restore solid cylinder function.

Ignition Lock Cylinders Across Makes

From trucks to imports, ASP ignition cylinders cover a broad make/model range:

• 2004–2012 Chevy Colorado / B110 Cylinder (C-24-116)
• 2001-2019 Ford Ignition Lock Cylinder / Un-Coded / (C-42-197)
• 1995–2018 Ford 8-Cut H75 Cylinder (ASP-C-42-184)

• 1996–2001 Ford/Mercury/Mazda H75 Uncoded Cylinder (C-42-195) 
  
  

Each aftermarket cylinder, not a cheap parts-store substitute, meets professional standards with exact-fit tolerance for smoother locks and ignition systems.
