Ford Five Hundred Ignition Lock Cylinders
Ford Five Hundred Ignition lock cylinders
Starting at $52.95, AutoBuffy stocks 7 ignition lock cylinders from Dorman, Motorcraft, and Standard Ignition to fit the Ford Five Hundred. The ignition lock cylinder is the mechanical tumbler your key turns to start the engine and supply power to accessories. When it wears out or fails, the key may not turn, get stuck, or the vehicle may not start at all.
Signs your Ford Five Hundred needs a new ignition lock cylinder
- Key will not turn in the ignition even when the steering wheel is not locked
- Key turns but the engine does not crank or receive any electrical signal
- Key gets stuck in the ignition and cannot be removed after shutting off the engine
- Ignition feels stiff, gritty, or requires excessive force to rotate through key positions
- Vehicle starts intermittently — sometimes normal, sometimes completely unresponsive
- Warning lights or accessories fail to activate when the key is turned to the 'ON' position
Which ignition lock cylinder should you buy for your Ford Five Hundred?
The main decision is whether you need a cylinder alone or a cylinder pre-cut and coded to your existing key. Some cylinders ship without a key wafer set and must be re-keyed by a locksmith, while others come ready to use. Also confirm whether your Ford Five Hundred uses a combined ignition lock and switch assembly or a separate cylinder.

Replacing an ignition lock cylinder on a Ford Five Hundred
Moderate⏱ 1–2 hoursSteering column trim removal tools or flathead screwdriversPin punch or small pick to press the cylinder release tabPhillips and Torx screwdriversTrim panel pry toolReplacement key (if using a pre-coded cylinder)
Replacing the ignition lock cylinder on the Ford Five Hundred requires removing the steering column shroud to expose the cylinder housing, then depressing a spring-loaded release tab while the key is held in a specific position — usually 'ACC' or 'RUN' — to slide the old cylinder out. The new cylinder slides in until it clicks, and the shroud is reinstalled. If the replacement cylinder needs re-keying, complete that step before final installation to confirm the key operates smoothly.
Frequently asked questions
How much does it cost to replace ignition lock cylinders on a Ford Five Hundred?
Parts start at $52.95 on AutoBuffy. Add shop labor — typically one to two hours at your local rate — plus locksmith or dealer fees if re-keying is required. Choosing a pre-coded cylinder can reduce total cost by eliminating the re-keying step entirely.
Can I replace the ignition lock cylinder on my Ford Five Hundred myself?
Most experienced DIYers can handle this job with basic hand tools and a steering wheel lock pin or release tool. The main challenge is accessing the release tab on the cylinder while the ignition is in a specific key position. A repair manual for the Ford Five Hundred is strongly recommended before starting.
Will a new ignition lock cylinder work with my existing key on the Ford Five Hundred?
Not automatically. A blank replacement cylinder must be re-keyed by a locksmith or dealer to match your current key cut. Pre-coded cylinders come with a new key but will not match your doors or trunk. Confirm which scenario fits your situation before purchasing.
What causes an ignition lock cylinder to fail on the Ford Five Hundred?
Normal wear on the internal key wafers is the most common cause, especially on high-mileage vehicles. Worn or damaged keys accelerate wafer wear. Attempted theft or forced entry can bend or break internal components. Dirt and debris entering the cylinder over time also degrades smooth rotation.
Is the ignition lock cylinder the same as the ignition switch on the Ford Five Hundred?
No. The lock cylinder is the mechanical tumbler the key physically enters and rotates. The ignition switch is the electrical component directly behind it that sends power to the starter and accessories. On some Ford Five Hundred designs they are one combined unit; on others they are separate serviceable parts.
How long do ignition lock cylinders last on the Ford Five Hundred?
Most cylinders last the lifetime of the vehicle under normal use, but many begin to show wear after years of daily operation or if a worn key has been used consistently. Rough handling, a heavy keychain, or a prior forced-entry attempt can significantly shorten service life.
