Ford Explorer Ignition Lock Cylinder Guide for 1991-1995 Models
Having trouble with a stuck key or an Explorer that won't start? Your ignition lock cylinder is a likely suspect.
- Failure is common on the 1991-1995 Explorer due to age; symptoms usually involve the key sticking or not turning.
- Replacement is simple for a DIYer; it requires turning the key to 'ON' and depressing a retaining pin under the steering column shroud.
- Most aftermarket kits from brands like Dorman and Standard can be re-keyed to match your original keys, avoiding the need for a separate ignition key.
- This is a mechanical part; if you have electrical issues but the key turns smoothly, the problem may be the separate electronic ignition switch instead.
Common Symptoms of a Failing Ignition Lock Cylinder
On a first-generation Ford Explorer, the ignition lock cylinder is a frequent point of failure due to simple wear and tear. When it starts to go bad, you'll notice very specific problems related to your key. Ignoring these signs can leave you stranded.
Key Failure Symptoms
- Key Won't Turn: This is the most common failure. You insert the key, but it refuses to turn to the 'run' or 'start' position. This can be caused by worn tumblers inside the cylinder or a worn-out key. Sometimes, wiggling the steering wheel can help if the steering lock is bound.
- Key is Hard to Insert or Remove: You might feel resistance, or have to jiggle the key to get it in or out of the ignition. This indicates the tumblers are not aligning properly.
- Key Gets Stuck: The key may turn, but then get stuck in one position, such as 'accessory' or 'run', making it impossible to turn off the vehicle or remove the key.
- No Start or Intermittent Power: While often a sign of a bad ignition switch, a worn lock cylinder can fail to properly engage the switch, leading to a no-start condition or flickering accessory lights.
Choosing the Right Aftermarket Ignition Lock Cylinder
For a 1991-1995 Explorer, new OEM Motorcraft parts are scarce. The aftermarket offers several reliable options that meet or exceed original quality. Most replacement kits for this vehicle come with new tumblers and springs, allowing you to re-key the new cylinder to match your original keys, so you don't have to carry separate keys for the door and ignition.
Brand Quality Tiers
- Standard Motor Products (Standard Ignition): Often considered a top-tier aftermarket brand, Standard parts are trusted by professional technicians for their precise fit and durability, closely matching OE standards. They use quality materials like brass tumblers for smooth, long-lasting operation.
- Dorman: A well-known and cost-effective brand, Dorman is a popular choice for DIY repairs. Their kits are typically comprehensive and may include design improvements over the original part. They are a solid, budget-friendly option.
- Replacement: This is often a private-label brand that offers a functional, no-frills part at the lowest price point. It's a viable choice for those on a tight budget who need to get their Explorer back on the road.
Pro Tip: Re-keying Your New Cylinder
Most aftermarket cylinders for this Explorer are designed to be re-keyed. The process involves disassembling the new cylinder, inserting your original key, and placing the new color-coded or numbered tumblers into the slots. The goal is for all tumblers to sit flush when the key is inserted. It's a straightforward process, and instructions are usually included.

Frequently Asked Questions (FAQ)
Can I reuse my original keys with a new cylinder?
Yes. Most aftermarket kits for the 1991-1995 Explorer are designed to be re-keyed using the included tumblers. This allows you to continue using your original keys for both the ignition and doors.
What's the difference between the ignition lock cylinder and the ignition switch?
The lock cylinder is the mechanical part your key goes into. The ignition switch is the electronic component behind it that sends power to the vehicle's systems. The cylinder turns the switch. They are separate parts on this vehicle.
My key is stuck and won't turn. How can I remove the old cylinder?
The cylinder must be in the 'ON' or 'RUN' position to be removed. First, try turning the steering wheel back and forth while gently trying to turn the key to release pressure on the steering lock. If that fails, a small spray of a dry lubricant like graphite can help. As a last resort, the cylinder may need to be drilled out by a mechanic or locksmith to be removed.
Are there any recalls for the ignition lock cylinder on my Explorer?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database did not show any recalls or technical service bulletins (TSBs) specifically for the ignition lock cylinder on 1991-1995 Ford Explorers. Failures are typically due to age and normal wear.
