Recognizing the Signs

If you're experiencing this issue, you're not alone. Here's what's typically happening and how to address it.

What You Might Notice

Yes, you can replace a hard-to-turn ignition key cylinder yourself with average mechanical skills.

Understanding the Problem

Understanding why ignition keys become difficult to turn helps prevent future issues:

• Worn cylinder pins: After 15+ years, the internal pins wear down and don't align properly with your key
• Dirty or corroded contacts: Moisture and dirt can accumulate inside the cylinder
• Key wear: Daily use gradually wears down the key's teeth
• Steering wheel pressure: Parking with the wheel turned puts pressure on the ignition lock
• Temperature changes: Metal expansion and contraction can affect cylinder tolerances

What to Grab

• New ignition lock cylinder (specific to your chassis)
• Phillips and flathead screwdrivers
• Socket wrench set
• Wire strippers and electrical tape
• Multimeter
• Penetrating oil (like WD-40)
• Safety glasses
• Work gloves

Working Through It

1. Safety first: Park on level ground, engage parking brake, and disconnect the negative battery terminal to prevent electrical shorts
2. Remove steering column covers: Most 2007 Fleetwood RVs use Ford or Chevy chassis. Remove the upper and lower plastic covers around the steering column using Phillips screws
3. Locate the ignition cylinder: Find the ignition switch assembly behind the steering wheel. Note the wire harness connections and take photos for reference
4. Remove the old cylinder: Turn the key to the ACC position. Look for a small release pin or tab on the cylinder housing. Press this while pulling the cylinder out
5. Disconnect wiring: Carefully disconnect the wire harness from the back of the ignition switch. Label wires if necessary
6. Install the new cylinder: Ensure the new cylinder is coded to match your existing key, or transfer the tumbler configuration from the old cylinder. Insert the new cylinder with the key in the ACC position. It should click into place when properly seated
7. Reconnect wiring: Attach the wire harness to the new switch, ensuring all connections are secure
8. Test operation: Before reassembling, reconnect the battery and test all key positions (Off, ACC, On, Start)
9. Reassemble: Replace steering column covers and tighten all screws

Situations That Need a Professional

Consider professional help if you encounter:

• Anti-theft system complications: Modern RVs may have chip keys or immobilizers that require programming
• Steering column damage: If covers are cracked or components seem damaged
• Electrical issues: Multiple electrical problems or if your multimeter shows unexpected readings
• Key programming needs: If your RV has a transponder key system
• Airbag-equipped steering wheels: These require special handling procedures
