Key Takeaways
  • Fitment is critical; parts are different for 1957-59, 1960-65, and 1966-69 models.
  • Replacement is a simple DIY task that usually takes less than 30 minutes with the old key.
  • The new cylinder comes with a new set of keys, which will not match your door locks.
  • This part is mechanical; if you have electrical issues (like no power at all), check the ignition switch and battery first.
The ignition lock cylinder is the mechanical tumbler assembly where you insert and turn your key. Its job is to verify the correct key is being used and then activate the ignition switch, which is a separate electronic part. When you turn the key, the cylinder rotates and moves a rod that tells the ignition switch to send power to start the vehicle and run its accessories. It also serves as a basic security device, preventing the vehicle from being started without the proper key.

Is Your Ignition Lock Cylinder Failing?

For a classic truck like the 1957-1969 Ford Ranchero, the ignition lock cylinder can wear out from decades of use. The small metal tumblers inside get worn, causing a loose or sloppy feel. You might also find the key is difficult to insert, gets stuck, or won't turn at all. If your dashboard lights and radio turn on but the engine won't crank, the problem could be the lock cylinder failing to fully engage the ignition switch.

Critical Fitment Information for 1957-1969 Ranchero

Warning: The 1957-1969 Ford Ranchero was built on several different platforms. There is NO single ignition lock cylinder that fits all years. You must verify the part is correct for your specific year.

  • 1957-1959: Based on the full-size Ford platform.
  • 1960-1965: Based on the compact Falcon platform.
  • 1966-1969: Based on the larger Fairlane/Torino platform.

Always use a fitment checker to ensure you are buying the correct part for your exact year and model.

Choosing an Aftermarket Ignition Lock Cylinder

For a vehicle of this age, New Old Stock (NOS) Ford parts are extremely rare and expensive. Aftermarket parts are the most practical and affordable solution. The two most common brands you will find are Dorman and Standard Ignition (Standard Motor Products).

  • Standard Ignition (SMP): Often considered a top-tier aftermarket brand, Standard parts are known for quality construction with components like brass tumblers and die-cast zinc cores that meet or exceed original specifications. Forum users often recommend them for reliability.
  • Dorman: Dorman is a well-known brand that produces a huge range of replacement parts. Their ignition lock cylinders are a reliable and cost-effective direct replacement that matches the function of the original part.

Pro Tip: For a simple, mechanical part like this on a classic vehicle, both Dorman and Standard Ignition offer dependable quality. The new cylinder will come with a new set of keys.

Replacement Cost

Replacing the ignition lock cylinder is an affordable repair. The parts are inexpensive, and if you have a shop do the work, labor should be minimal.

Part SourceEstimated Cost
New Aftermarket$16.60 - $26.90
New OEM (NOS)$75 - $200+ (if found)
Used OEM$20 - $50 (not recommended due to age)
Shop Labor$60 - $150

Frequently Asked Questions (FAQ)

Is the ignition lock cylinder the same as the ignition switch?

No. The lock cylinder is the mechanical part your key goes into. The ignition switch is the electronic component that the cylinder activates. If you can turn the key but nothing happens (no lights, no radio), the problem may be your ignition switch, not the lock cylinder.

Is this a difficult part to replace myself?

No, this is a very DIY-friendly job for most 1960s Fords. The process typically involves turning the key to the 'Accessory' position, inserting a paperclip or small punch into a release hole on the face of the cylinder, and then pulling the cylinder straight out. The entire job usually takes less than 30 minutes.

Do I need my old key to replace the cylinder?

Yes, having the old key makes the job much easier because you need to turn the cylinder to the 'Accessory' position to press the release pin. If you don't have the key, the cylinder will likely need to be drilled out by a locksmith.

Will my original door keys still work?

No. The new ignition lock cylinder will come with a new, unique set of keys. Your old keys will continue to work for the doors, but you will now have a separate key for the ignition.

Are there any recalls for the ignition on my Ranchero?

No. Searches on the National Highway Traffic Safety Administration (NHTSA) database show no open recalls for the ignition lock cylinder on 1957-1969 Ford Rancheros. Major Ford ignition-related recalls occurred for much newer models (1988 and later).
