Why won't the key turn in my Suzuki Esteem's ignition?

Short answer: Most often the steering lock is under pressure, so turn the wheel firmly side to side while gently turning the key. In very cold weather, the grease inside the lock can thicken; warming the key area with a hair dryer and using the spare key are the next steps. If it keeps happening, the lock cylinder or ignition switch may be wearing out.

Symptom: You put the key in and it won't turn at all, even while wiggling the wheel. It tends to happen on cold mornings or when parked on a slope.

What to check first

1. Turn the steering wheel firmly both ways while gently turning the key. The steering lock pin can bind against the cylinder.
2. If you're parked on a hill, have someone push the car slightly to take pressure off the transmission and lock.
3. Try the spare key. A worn key may no longer line up the pins inside the lock.
4. In deep cold, warm the column area with a hair dryer for a few minutes. Avoid open flame.
5. Lubricate the lock with white lithium grease through a small straw, as one member recommended. Graphite is meant for dry locks.

Likely causes

1. Steering lock binding. The most common cause and free to fix by turning the wheel.
2. Grease inside the lock thickened by cold. A Minnesota owner hit this on a frigid morning.
3. Worn key or lock cylinder. The spare key test tells you which.
4. Worn ignition switch. Replacing it means removing the plastic covers around the steering column.

What it usually costs

No owner posted a price. A locksmith or shop can quote a lock cylinder or ignition switch replacement, which can need new keys cut to match.

Is it safe to keep driving?

If the key won't turn, the car simply won't start, so there's no driving risk. Never force the key with tools; a broken key in the lock turns a free fix into a repair. Verify with a mechanic.

DIY or shop?

DIY for the wheel, spare key, warming and lube steps. Replacing the ignition switch is possible at home; one owner had to work out how to remove the steering column covers without cracking the plastic in 20°F weather, so warm them first.

What owners report

• In URGENT...I need help with a stuck ignition on Car Talk, a 2000 Esteem owner in Minnesota couldn't turn the key at all one morning, even while wiggling the wheel. Members suggested turning the wheel firmly while trying the key, trying the spare, warming the lock with a hair dryer because cold can thicken the grease inside, having someone push the car if parked on a hill, and using white lithium grease rather than graphite.
• In Replacing 1999 Suzuki Esteem Ignition Switch on Car Talk, a 1999 Esteem owner replacing the ignition switch asked how to get the plastic cover off the steering column without breaking it in 20°F weather, and later said they figured it out.

Quick tip

Nine times out of ten this is the steering lock, not a broken part. Firm wheel pressure and a gentle key usually does it. Save the switch replacement for when it keeps coming back.

Safety / mechanic note

Never force a stuck key with pliers; a snapped key means a locksmith visit. Verify with a mechanic.
