Ford GT Ignition Lock Cylinder Guide for 2005-2006 Models
Everything you need to know before replacing the ignition lock cylinder on your 2005-2006 Ford GT.
- Before replacing the ignition cylinder, always check the battery and frame ground connections first, as these are the most common cause of starting issues on a Ford GT.
- The 2005-2006 Ford GT likely does not use a chipped (PATS) key, so programming new keys is not required for an aftermarket cylinder.
- Replacement is a simple mechanical job that is feasible for most DIY-inclined owners and takes about an hour.
- A high-quality aftermarket brand like Standard Ignition is a reliable choice for this part.
Is Your Ignition Cylinder Failing?
On the 2005-2006 Ford GT, problems with starting are very common, but they are rarely caused by the ignition lock cylinder. Before suspecting this part, you must check for more frequent issues.
Check Battery and Grounds First
The Ford GT is known for having starting issues related to a weak battery or poor electrical grounds. Forum discussions among owners consistently point to these two areas as the primary cause of no-start or no-crank conditions. Symptoms like a completely dead car (no lights, no sounds) often trace back to a loose or corroded ground cable, not a faulty ignition cylinder. Always rule out battery and grounding problems before deciding to replace the lock cylinder.
However, the lock cylinder is a mechanical part that can wear out. Symptoms point specifically to the key and cylinder interaction:
- Key is hard to insert or remove: You feel resistance or a gritty sensation.
- Key sticks while turning: The key gets stuck in the ACC, ON, or START position.
- You have to jiggle the key: The car only starts if you wiggle the key in the cylinder.
- The key won't turn at all: The internal tumblers are worn or jammed, preventing rotation.
Choosing the Right Aftermarket Ignition Cylinder
Since OEM Ford parts for the GT can be difficult to find and expensive, the aftermarket is a practical source for a new ignition lock cylinder. The key difference between available brands is typically build quality and reputation.
Brand Tiers
- Standard Ignition (Standard Motor Products): This is a well-regarded aftermarket manufacturer known for producing parts that meet or exceed original specifications. They use quality materials like brass tumblers and die-cast zinc cores, ensuring reliable, long-term operation. For a vehicle like the Ford GT, choosing a reputable brand like Standard Ignition is a sound investment.
- Replacement: This is often a generic or store-brand option. While it can be more budget-friendly, the materials and manufacturing tolerances may not be as consistent as a premium brand. It can be a viable option, but for a specialty vehicle, the peace of mind from a known brand is often worth the small price difference.
A Note on Keys and Programming
The 2005-2006 Ford GT does not appear to use Ford's PATS (Passive Anti-Theft System) transponder chip in the key. This is a major advantage. It means you do not need to worry about expensive key programming at a dealership. The new keys that come with your aftermarket lock cylinder should work to start the car immediately after installation. You will, however, now have a separate key for the ignition and the doors.
Estimated Replacement Costs
The cost to replace the ignition lock cylinder is reasonable because it does not require programming and is relatively easy to access.
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket Part | $33 - $77 |
| Shop Labor | $90 - $150 |
| Total Estimated Cost | $123 - $227 |
Frequently Asked Questions (FAQ)
How do I know if my starting problem is the ignition cylinder or the battery?
If you turn the key and hear clicking, or the lights are dim and nothing happens, your problem is almost certainly the battery or a bad connection. If the battery is strong and all accessories work, but the key physically will not turn in the ignition, the problem is likely the lock cylinder.
Is replacing the ignition lock cylinder a difficult job?
No, for most Fords of this era, it is a relatively simple DIY task. The general procedure involves removing the steering column shrouds, turning the key to the 'ON' position, and using a small punch or screwdriver to depress a retaining pin that releases the cylinder. It can typically be done in under an hour.
Will I need to get the new keys programmed?
Based on available part information, the 2005-2006 Ford GT does not use a transponder key system. Therefore, no programming is necessary. The new keys should work right away.
Should I really use an aftermarket part on my Ford GT?
For a simple, mechanical part like the ignition lock cylinder, a high-quality aftermarket component from a brand like Standard Ignition is a perfectly acceptable and reliable choice. Given the age of the vehicle, OEM parts may be unavailable or prohibitively expensive, making aftermarket the most practical solution.
