You put the key in, it slides all the way home — and it won’t budge. Before you assume the worst, run through these causes in order. The first one fixes it more often than anything else.
1. The Steering-Wheel Lock Is Engaged
If the wheel was turned after the key came out, the column lock binds the ignition cylinder. Fix: turn the steering wheel gently left and right while turning the key at the same time. When the pressure releases, the key turns. This is the single most common cause and costs nothing.
2. The Key Is Worn
Every insertion wears the cuts down a little. After years of use the peaks and valleys no longer lift the pins to the right height. A telltale sign: the spare (used rarely) works, but the everyday key doesn’t. Fix: have a fresh key cut from the factory code rather than copying the worn key — copying a worn key copies the wear.
3. The Ignition Cylinder Is Worn or Jammed
If every key sticks, the wear is on the lock side. Wafers inside the cylinder deform, or debris jams the works. Forcing it can snap the key off inside — which turns a repair into an extraction as well. Fix: a locksmith can service or replace the cylinder at your location; see ignition repair.
4. It’s the Wrong Key
It happens more than anyone admits — same-brand keys look identical, and a household with two vehicles of the same make mixes them up. If the key slides in but won’t rotate at all, check the keychain.
What Not to Do
- Don’t force it — a snapped blade adds broken-key extraction to the bill.
- Don’t spray household lubricants into the cylinder; some attract grime and make it worse.
- Don’t start disassembling the steering column — airbag systems live there.
