1960-1968 Mercury Montclair Ignition Lock Cylinder Replacement Guide
If your key is stuck, hard to turn, or won't start your Montclair, this guide is for you.
- If you have a working key, replacement is a very easy 10-minute job using a paperclip.
- Failure to replace a failing cylinder will eventually leave you stranded.
- Aftermarket cylinders come with new keys; your original door keys will not work in the new ignition.
- Both Standard Ignition and Dorman are reliable, widely available aftermarket brands for this part.
Is Your Ignition Lock Cylinder Failing?
After decades of starting your car, the small metal parts inside the ignition lock cylinder on a classic 1960-1968 Mercury Montclair will naturally wear out. This isn't a sign of a major problem with the car itself, but a simple mechanical failure of a part that's seen a lot of use. Symptoms often start small and get worse, and ignoring them can eventually leave you stranded.
Common Symptoms of a Bad Lock Cylinder
- Key Won't Turn: This is the most common sign. The key might feel completely stuck in the 'Off' or 'Accessory' position and refuse to budge.
- Difficulty Inserting or Removing Key: You might feel a gritty sensation or have to jiggle the key to get it in and out of the cylinder. This indicates worn or misaligned internal pins.
- Car Won't Start: The cylinder can become so worn that it no longer properly engages the ignition switch behind it. 🎬 Watch how to remove the ignition cylinder and switch together. You'll turn the key, but nothing happens—no cranking, no sound.
- Key Feels Loose or Sticks: If the key feels sloppy in the ignition or gets stuck in certain positions (like 'On' or 'Start'), the cylinder's internal components are likely failing.
Lock Cylinder vs. Ignition Switch
It's important to know the difference. The lock cylinder is the mechanical part your key goes into. The ignition switch is the electrical part behind it that the cylinder controls. If your accessories (radio, lights) work but the car won't crank, or if you have no power at all, the problem might be the switch, not the cylinder.
Choosing the Right Aftermarket Ignition Cylinder
For a classic vehicle like the Montclair, new original equipment (OEM) Ford parts are essentially unavailable. The market consists of reliable aftermarket brands that produce direct-fit replacements. For a simple, mechanical part like this, aftermarket quality is excellent for daily use.
Brand Tiers for Your Montclair:
- Standard Ignition (SMP): Often considered a premium aftermarket brand, Standard Motor Products has a long reputation for making high-quality parts that meet or exceed original specifications. Technicians often trust them for their precise fit and durability.
- Dorman: Dorman is a well-known and reliable aftermarket supplier that provides cost-effective replacement parts. They are a solid choice for this repair and are widely available. Forum users often report good experiences with Dorman for classic vehicles.
Both Standard Ignition and Dorman are excellent choices for this part. The functional difference between them for your Montclair is minimal. The best choice is often the one that is most readily available to you.

Frequently Asked Questions
Is this a difficult repair to do myself?
No, this is a very easy DIY job for most owners. If you have a working key, the cylinder can be removed in minutes. You simply turn the key to the 'Accessory' position, insert a paperclip or small wire into the pinhole on the face of the cylinder to depress a retaining pin, and then pull the cylinder straight out.
🎬 Video guide on removing the lock cylinder using a key.Will my original keys work with the new cylinder?
No. A new aftermarket ignition lock cylinder will come with a new, unique set of keys. You will then have one key for the ignition and your original key for the doors and trunk.
What if I lost my key? Can I still replace it?
Yes, but the process is more difficult. Without the key to turn the cylinder to the 'Accessory' position, you cannot easily depress the retaining pin. The most common method is to carefully drill out the center of the lock cylinder to destroy the pins, allowing you to turn and remove it. This requires caution to avoid damaging the surrounding ignition switch housing.
🎬 See how to change an ignition cylinder with or without keys.Should I try lubricating my old cylinder first?
You can try spraying a small amount of dry graphite lubricant into the keyhole. This can sometimes provide a temporary fix if the issue is minor sticking. However, if the internal pins are already heavily worn or broken, lubrication will not solve the problem, and replacement is the only reliable solution.
