"Can I replace ignition cylinder myself on 2007 Fleetwood RV?"

Read full question

After replacing my 2007 Fleetwood's ignition cylinder yesterday something still doesn't seem right — the key is still extremely hard to turn. I'm pretty sure it's the ignition cylinder that's worn out.

Is this something I can tackle as a DIY project? I have moderate mechanical skills but haven't worked on steering column components before. What's involved in replacing the ignition switch cylinder on this model?

Quick Answer

A hard-to-turn ignition key in your 2007 Fleetwood is typically caused by a worn ignition cylinder or key. This is a moderately challenging DIY repair that requires disconnecting the battery, removing the steering column covers, and replacing the ignition switch cylinder.

Recognizing the Signs

First thing to check: your ignition cylinder's internal springs and tumblers. Nine times out of ten, that's exactly where your sticky key problem is hiding. 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

Safety first: Park on level ground, engage parking brake, and disconnect the negative battery terminal to prevent electrical shorts
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
Locate the ignition cylinder: Find the ignition switch assembly behind the steering wheel. Note the wire harness connections and take photos for reference
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
Disconnect wiring: Carefully disconnect the wire harness from the back of the ignition switch. Label wires if necessary
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
Reconnect wiring: Attach the wire harness to the new switch, ensuring all connections are secure
Test operation: Before reassembling, reconnect the battery and test all key positions (Off, ACC, On, Start)
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
