If you have locked keys in car, the fastest legitimate fix is a spare key from someone you trust or a call to your roadside assistance provider. If neither works, a licensed Sydney locksmith can open most cars for about $205 (range $115–$345), with ID checked first.
This guide covers what to do first, what to avoid, why it happens, what a locksmith does and how to stop it happening again.
Key points
- First step: check that nobody, including a child or pet, is inside the car, and call 000 straight away if anyone is at risk.
- Do not wedge, pry or hit the door or window; damage to seals and paint costs far more than a call-out.
- A legitimate locksmith asks for ID and proof the car is yours before opening it, and gives you their NSW licence number.
- A car lockout in Sydney typically costs about $205, within a range of $115–$345 (October 2026).
Locked keys in car: do this first
- Check who is inside the car: if a child or animal is locked in, especially on a warm day, call 000 immediately and do not wait for a tradesperson.
- Move to a safe, visible spot if you are on a busy road, and switch on your phone torch if it is dark.
- Walk around the car and check every door and the boot, since a passenger door or boot may have been left unlocked.
- Contact whoever holds a spare key, such as a partner, parent or housemate, and ask them to bring it.
- Call your roadside assistance provider or check whether your car insurance includes lockout help, as some memberships cover it at no extra cost.
- Call a licensed locksmith if none of those work, and ask for their licence number before they begin.
Locked keys in car: what not to do
- Do not smash a window, because replacing laminated or tempered glass costs far more than a locksmith and leaves the car exposed.
- Do not wedge or pry the door frame with screwdrivers or wedges, which bends the frame and tears weather seals.
- Do not use coat hangers, wires or tools from the internet, as they scratch paint, damage wiring and can set off the airbag or alarm.
- Do not leave a child or pet inside while you wait for help; vehicle interiors heat up quickly, so call 000 if anyone is at risk.
- Do not hire from ads with no business name, because unlicensed call-centre operators often quote low and then add charges on site.
- Do not hand over the car without ID checks: a real locksmith asks you to prove ownership before opening the car.
Why you end up with locked keys in car
| Cause | Sign | Fix | Who |
|---|---|---|---|
| Keys left on the seat or in the boot | Doors lock behind you as you step out | Use a spare key or a licensed locksmith | Spare holder or locksmith |
| Auto-lock closes doors | Car locks itself after you start moving or get out | Check the vehicle settings with your dealer | You or the dealer |
| Flat key fob battery | Fob does nothing when you press it | Replace the fob battery; see our key fob guide | You or a locksmith |
| Worn or heavily copied key | Key turns stiffly or the door lock sticks | Cut a fresh key from the original | Locksmith |
| Lost key, no spare | Key cannot be found anywhere | New key cut and programmed | Auto locksmith |
| Remote central locking fault | Fob works only some of the time | Diagnose and repair the locking system | Dealer or auto locksmith |
On older cars we often see worn door-lock cylinders, where years of daily use make the key and lock stop agreeing with each other.
What a licensed locksmith does to open your car
- Confirms the price and arrival time by phone, including any after-hours surcharge, before travelling.
- Checks your ID and proof that the car is yours, such as registration papers, before touching the vehicle.
- Assesses the car and lock type so the right non-destructive method is chosen.
- Opens the car without damage using professional tools, and avoids drilling or breaking glass.
- Tests the doors and keys once you are in, and checks that the central locking still works properly.
- Offers a spare key cut from the original, if you want one, then gives you an itemised tax invoice.

How to avoid locked keys in car next time
- Keep a spare in a key safe at home or with someone you trust; compare options in our key safes and lock boxes guide.
- Replace the fob battery early using our car key battery replacement guide, so a flat fob never leaves you stranded.
- Learn your fob and its functions with our key fob guide, including whether your car has a physical backup key.
- Get a duplicate cut now rather than after a loss, because copying an existing key is much cheaper than cutting and programming from scratch.
- Make a habit of checking for keys, phone and wallet before closing the door, especially when carrying shopping or children.
- Consider keyless solutions for home access; see our smart locks guide and types of door locks.
