If a child or pet is locked inside, call Triple Zero (000) straight away. If not, move into shade first. Then find out who holds your nearest spare key. Finally, choose the quickest safe way in: roadside assistance, a locksmith, or someone handing your spare to a courier who brings it straight to your car.
Check who or what is inside the car first: children, pets and medicine
Before you think about keys, look through every window. What is inside the car decides how fast you need to move and who you call first.
If a child or an animal is locked in, call Triple Zero (000) now and tell the operator. Do this before you ring anyone about a spare key, a locksmith or roadside help. A key travelling across town takes time that a child or pet in a closed car may not have.
Cars heat up quickly. In testing reported by ABC News in 2015, Ambulance Victoria found that "on a 29 degrees Celsius day, the inside of a car would reach 44C within 10 minutes and 60C within 20 minutes." The testing is several years old, but the lesson still applies: even on a day that feels pleasant, the minutes count.
The same report noted that some triple-zero calls come from people who accidentally locked their keys in the car with their child. If that happens to you, calling for help is exactly the right move.
Medicine is the other thing to look for. Insulin, an asthma reliever, an adrenaline autoinjector or a child's antibiotics can easily sit in a bag on the back seat.
The Sydney Children's Hospitals Network warns: "Cars are not well insulated, and sunlight exposure will quickly heat the car temperature by up to 30 degrees higher than the outside temperature." So if someone will need that medicine soon, say so on every call you make, and once you are back in, ask a pharmacist whether it is still fine to use after sitting in the heat.
- A child or pet inside: call Triple Zero (000) now.
- Medicine someone needs soon: mention it when you call for help, and if the person who needs it becomes unwell, call Triple Zero (000).
- Bags, shopping or your phone: move into shade and start tracking down the spare.
How to track down your nearest working spare key in a few calls
The nearest working spare is the one that can reach your car soonest, which is not always the closest on a map. A spare at home with someone in is often quicker than one in a partner's bag at an office they cannot leave.
If your phone is locked in the car too, ask at a shop or service station counter to use their phone, or borrow one from someone nearby. Start with the numbers you know by heart.
Call in this order, and stop as soon as you reach someone who can help:
- Whoever is at home right now: a partner, housemate, adult child or visiting parent.
- A family member who carries a spare on their own key ring.
- A trusted neighbour or friend who holds a copy.
Ask each person four quick questions:
- Can you put your hands on the spare right now?
- Is it a key that starts the car, or one that only opens the doors?
- Can you leave, or are you tied up with a sleeping baby, work or no car of your own?
- Will you be there to meet someone at the door if the key is collected?
Their answers point to your next move. If they can drive the spare to you, that is usually simplest. If they have the key but cannot leave, someone else needs to carry it.
And if the only spare is inside a locked house with nobody home, a key delivery cannot happen. Go straight to roadside help or a locksmith instead.
The same applies on a road trip. If the spare is at home in Melbourne and you are locked out in a country town hours away, roadside help or a local locksmith is the realistic choice.
Choosing between roadside help, a locksmith and having your spare key brought to you
Each way back in suits a different situation. The right one depends on what you already have: roadside cover, a working spare, someone free to hand it over, or none of these.
| Option | Best when | Have ready |
|---|---|---|
| Roadside assistance | You hold roadside cover, nobody can reach your spare, or you are on a highway or far from home | Membership details, the car's registration and your exact location |
| A locksmith | There is no spare, the spare is lost, or the car needs a new key cut and programmed | Identification, registration details and the car's make, model and year |
| Your spare key brought to you | A working spare is in the same city, an adult can hand it over, and nobody vulnerable is inside | A sealed envelope, the exact spot where you are waiting and a phone number that answers |
Leave wire coat hangers and online tricks alone. On modern cars they can damage the door or its wiring, which may turn a lockout into a repair.
A locksmith or roadside service may ask for proof that the car is yours before opening it. If your licence and registration papers are in the glovebox, say so when you call and ask what else they will accept.
If the spare is coming by courier, let the person holding it make the booking, because they know the pickup address and can be at the door. Bookings for urgent personal deliveries such as keys and documents generally ask for a pickup address, a drop-off point and a contact at each end, so gather those before anyone books.
Not every lockout needs a dash. If you are safe at work and the car can stay in the staff car park until home time, a three-hour express delivery across town can bring the spare from home before you finish for the day.
How to hand over a spare key so it reaches your car quickly and safely
A spare key travelling across town needs two things: packaging that keeps it safe, and instructions that get it to the right car without a string of phone calls.
For the person at home:
- Press a button on the fob before sealing it. If the light flashes weakly or not at all, send another spare if there is one.
- Put the key in a small envelope, padded if it is a fob, and seal it with tape.
- Remove any tag showing your home address. Write only your first name and the drop-off point on the envelope.
- Hand the envelope to the driver at the door rather than leaving it in a letterbox or under a mat.
For you, waiting near the car, send the key holder every detail a stranger would need to find you:
- The name of the car park or street, the level and row, and the nearest entrance or landmark.
- The car's colour, body type and number plate.
- Where you will actually be waiting, such as just inside the supermarket entrance, so you are not standing by the car in the sun.
- A number that will answer, even if it is a borrowed phone or the shop's landline.
When minutes matter, ask for a direct, dedicated delivery with no other stops. In plain words, one driver collects the key and goes straight to you, without picking up or dropping off anything else on the way.
Here is a worked example of how it can come together. You have locked the keys in at a shopping centre car park in Brisbane's south on a warm afternoon. Your partner is at home across town with a toddler who has just gone down for a nap, so driving over is not an option.
Your partner seals the spare in an envelope, books a direct delivery and meets the independent driver who accepts the job at the front door. They text you the driver's details, and you wait inside the centre beside the entrance closest to the car.
When the driver arrives, open the envelope and try the key straight away. If it opens the door but will not start the engine, you can call roadside help on the spot rather than losing more time.
Waiting safely in Australian heat while your key is on its way
A summer lockout is a heat problem as much as a key problem. The Bureau of Meteorology recorded summer 2024 to 2025 as Australia's second-warmest on record since national observations began in 1910, 1.89 °C above the 1961 to 1990 average. So plan where you will wait as carefully as how the key will reach you.
The best places to wait, in order of preference:
- Inside an air-conditioned shop, library, café or service station with a view of the car park.
- A shaded bench or covered walkway close to the car.
Drink water while you wait, even if you do not feel thirsty, and keep any children with you in the shade and drinking too. If you or anyone with you feels faint, confused or unwell in the heat, call Triple Zero (000).
If your phone is with you, lower the screen brightness and close apps you do not need so the battery lasts until the key arrives. If it is locked in the car, agree a callback number with the key holder before you hang up.
Check the parking signs while you still can. If a timed bay runs out or a clearway starts before the key is likely to arrive, tell whoever is helping, because roadside help may then be the quicker choice.
Evening lockouts bring a different concern. After dark, wait somewhere lit and staffed, like a service station counter or a shopping centre information desk, and tell the driver that is where you will be.
A household spare key plan to set up before summer
A lockout plan takes a single evening to set up, and spring is the time to do it. The Bureau of Meteorology's annual climate statement for 2025 describes Australia's fourth-warmest year since national records began in 1910, so it pays to be ready before summer.
- Two spares, two places. Keep one at home and one with a trusted person who is usually home on weekdays, such as a retired parent or a neighbour who works from home. If your car has only one spare, consider having another cut and programmed.
- Test every spare. Check that each one both opens and starts the car. A plain cut key may turn the lock but not the engine.
- Refresh the fob battery. Replace the battery in a spare fob if the buttons respond slowly, and stick a note on the fob's storage spot with the date you changed it.
- Write down the essentials. Keep the key holders' numbers and your registration details on a card in your wallet and another in a bag you carry, so a locked car does not take them all with it.
- Agree who books. Decide now that whoever holds the spare arranges the pickup, so nobody works it out on the day.
- Give children something else to hold. The Queensland Family and Child Commission notes that a frequent lock-in happens when a parent hands the car keys to a child, who then locks the car by accident while the parent is outside. A toy or a drink bottle keeps little hands just as busy.
Two more habits help. Keep the keys in your hand until the door is shut, and on long road trips pack the spare in a different bag carried by another adult, so it travels with you instead of staying home.
Lockouts do not keep office hours, so agree how an evening or weekend handover would work and read how after-hours courier deliveries run once the working day ends.
Getting your spare key to your car with Zoom2u
When your spare key is safe at home and someone can hand it over, you can book a key courier through Zoom2u for same-day metro delivery. The independent driver who accepts the job collects the key from the door and brings it to your car.
If you want one trip with no other stops, choose the VIP Courier option: the independent driver who accepts the job collects the key and brings it straight to you. That suits the Brisbane car park example above, or a Melbourne commuter whose partner is home with the spare but cannot leave the house.
Evening and weekend lockouts can be booked as after-hours deliveries with live GPS tracking. That means you can follow the driver on a map from inside the shop and step out of the shade only when they are close.
Zoom2u is a marketplace that connects you with independent drivers, who choose which jobs to accept, so arrival times depend on traffic, distance and when a driver takes the job. Keep waiting somewhere cool, and keep the person at home ready at the door, until the key is in your hand.
Frequently asked questions
Will a spare key without a chip start my car?
Not always. A plain cut key or an unprogrammed copy may open the door but not start the engine, so check that your spare both unlocks and starts the car well before you ever need it, and replace the battery in a spare fob if the buttons respond slowly.
What can I do if my phone is locked in the car with my keys?
Ask a nearby shop or service station counter if you can use their phone, or borrow one from someone close by. Call the person who holds your spare key first, because they can arrange roadside help, a locksmith or a courier from their end while you wait in shade.
Will a locksmith or roadside service ask for proof the car is mine?
They may ask for identification or registration details before opening the car. If your wallet is locked inside, ask whoever is sending the spare key to include a copy of your licence or registration papers, or keep your registration details saved somewhere you can reach without the car.
Can someone else send my spare key if I am not at home?
Yes, as long as an adult with access to the spare can be there to hand it over. A partner, housemate or trusted neighbour can seal the key in an envelope, meet the driver at the door and share the exact spot where you are waiting, such as the car park level and nearest entrance.
