Key won't turn or gets stuck in your Tempo? Here's what you need to know about replacing the ignition lock cylinder.
- Replacement is very simple if the key still turns; no special tools are needed besides a small pick or screwdriver.
- The 1984-1994 Tempo does NOT require key programming, making aftermarket replacement easy.
- Be aware of the separate, major recall on the electronic ignition SWITCH for 1988-1993 models, which can cause fires.
- Aftermarket brands like Dorman and Standard Ignition are the most practical and reliable choices for this repair.
Is Your Ford Tempo Ignition Lock Cylinder Failing?
If you own an 1984-1994 Ford Tempo, the ignition lock cylinder is a part that can wear out from years of use. The small metal pins and springs inside, called tumblers, can get worn, dirty, or stuck. When this happens, you'll notice clear symptoms that make starting your car difficult or impossible.
Common Failure Symptoms
- Key is Hard to Turn: You might feel like you're using the wrong key, even when you're not. It may require jiggling or extra force to get the key to turn from the 'OFF' position.
- Key Gets Stuck: The key might turn to start the car but then refuse to turn back to the 'OFF' position, preventing you from removing it.
- Key Won't Go In or Comes Out Too Easily: A worn cylinder might prevent the key from inserting smoothly. Conversely, extreme wear could allow you to remove the key while the car is still running.
- Loose or Wobbly Key: When inserted, the key feels sloppy and has a lot of play. This indicates significant internal wear.
Important Recall Information: Ignition SWITCH vs. Lock Cylinder
In 1996, Ford issued a massive recall for a defective ignition switch, not the lock cylinder, on millions of vehicles, including the 1988-1993 Ford Tempo. This separate electronic switch could overheat and cause a fire, even when the car was parked and turned off. While the lock cylinder you are replacing is mechanical, it's crucial to be aware if your vehicle falls under this recall for the related electronic part. The lock cylinder turns the switch; a faulty switch is a serious fire hazard.
Choosing the Right Aftermarket Ignition Lock Cylinder
For a vehicle as old as the 1984-1994 Tempo, Original Equipment (OEM) parts are likely discontinued. The good news is that aftermarket brands offer quality, affordable replacements that are readily available. Your two main choices are Dorman and Standard Ignition (Standard Motor Products).
- Dorman: A well-known brand that produces a wide range of direct-fit replacement parts. Their lock cylinders are designed to match the original's function and are a reliable choice for a daily driver.
- Standard Ignition (SMP): A long-standing company trusted by professional technicians. They often highlight the quality of their materials, such as brass tumblers and die-cast zinc cores, designed to meet or exceed OEM specifications.
Honest Assessment: For a simple, non-electronic part like this on a Ford Tempo, both Dorman and Standard Ignition are solid choices. The quality difference is minimal for this application. Your decision can confidently be based on price and availability.

Frequently Asked Questions (FAQ)
Do I need to program the new keys for my 1984-1994 Tempo?
No. The 1984-1994 Ford Tempo does not use a chipped key or a PATS (Passive Anti-Theft System). The replacement is purely mechanical. You will simply use the new keys that come with the new cylinder.
What's the difference between the ignition lock cylinder and the ignition switch?
The lock cylinder is the mechanical tumbler assembly you put your key in. The ignition switch is the electronic component behind it that the cylinder activates. They are two separate parts. Symptoms like the key not turning are the cylinder; symptoms like the car having no power when the key is turned could be the switch.
How do I replace the cylinder if my key is stuck and won't turn to the 'RUN' position?
The standard replacement requires turning the key to 'RUN' to depress a release pin. If you cannot turn the key, you will likely need to drill out the center of the lock cylinder to destroy the tumblers and force it to turn. This is a more involved process.
Is replacing the ignition lock cylinder a DIY job?
Yes, for most home mechanics this is a very easy job. As long as your key can still turn, it takes only a few minutes with a simple tool like a pick or small screwdriver. No special steering wheel pullers are required for just the cylinder.
