Short answer

Stop forcing the key and move yourself away from traffic or other immediate danger. Try a spare key if one is safely available; otherwise, contact a roadside-assistance provider or qualified automotive locksmith.

Do not do these things

Do not keep twisting, bending, or repeatedly inserting a damaged key.
Do not use glue to reconnect a broken key in or near the lock or ignition.
Do not push a broken key fragment farther into the cylinder.
Do not insert screwdrivers, knives, wire, or other improvised tools.
Do not pry the door or try to break a window for a routine lockout.
Do not spray lubricant, penetrating oil, or cleaner into the lock or ignition unless the owner’s manual or a qualified professional says it is suitable.
Do not agree to drilling, a sharply increased price, or extra work without a clear explanation and updated total.
Do not remain close to moving traffic while trying to solve the key problem.

What to do now

Check your immediate safety. Move away from moving traffic when it is safe, and do not stand between the vehicle and passing vehicles. Call 911 if you are in immediate danger.
If a child or other person is locked inside and may be in danger from heat, cold, illness, or another urgent threat, call 911 immediately and follow the dispatcher’s instructions.
Inspect the key without inserting it again. Look for bending, cracks, missing metal, heavy wear, or a loose blade. Stop using it if it appears damaged.
If part of the key has broken off inside the door lock or ignition, leave the fragment in place and contact an automotive locksmith. Tell them exactly where the fragment is lodged.
Try a spare key if one is available and can be retrieved safely. If the spare works normally, stop using the damaged key.
If the key appears undamaged, confirm that it is the correct vehicle key. You may try another manufacturer-provided door or trunk lock if one is safely accessible, but stop if the key catches or requires force.
If an undamaged key enters a turn-key ignition but will not rotate, set the parking brake and, for an automatic vehicle, confirm the selector is fully in Park. Check the owner’s manual for the vehicle’s steering-lock procedure.
On many turn-key vehicles, pressure on the steering lock can prevent the key from turning. Apply only light turning pressure to the undamaged key while moving the steering wheel slightly left and right. Stop if the key bends, catches, or still will not turn.
Contact roadside assistance through your insurer, automaker, motor club, warranty, or other service plan. Explain whether the vehicle is locked, the key is visibly damaged, a fragment is inside a cylinder, or the ignition will not turn.
When contacting a locksmith, ask for an automotive locksmith and request the estimated total before dispatch. Confirm the business name, likely service, travel or after-hours charges, and whether extraction, replacement, or electronic programming may cost extra.
When the technician arrives, confirm that the company name matches the company you contacted. Where your state requires locksmith licensing, ask to see the applicable identification or license.
Have the vehicle identification number, year, make, model, photo identification, and proof that you own or are authorized to use the vehicle available. Tell the provider if the registration or other proof is locked inside.
Arrange towing or dealer service if the ignition appears damaged, the locksmith cannot safely restore access, or the vehicle requires key programming or another repair that cannot be completed where it is parked.

What can wait

You do not need to decide now whether to replace every key, change the vehicle’s locks, repair cosmetic damage, make an insurance claim, or choose a permanent repair provider. Focus first on personal safety, lawful access, and getting the vehicle secured or transported.

Important reassurance

Stopping before the key snaps or the cylinder is damaged can keep the problem smaller. Automotive locksmiths, roadside providers, repair facilities, and dealerships regularly handle broken keys, lockouts, key extraction, and ignition problems.

Scope note

This guide covers immediate safety, access, and service steps only. Key cutting, electronic programming, lock or ignition repair, insurance decisions, and suspected theft may require an automotive locksmith, repair facility, dealership, insurer, or law-enforcement agency.

Important note

This is general information, not legal, insurance, mechanical, security, or other professional advice. Vehicle systems, roadside coverage, locksmith licensing, and emergency procedures vary, so follow the vehicle owner’s manual and instructions from qualified local professionals.
