Car Keys Stolen? Rekey Your Car Before Thieves Come Back
Having your car keys stolen creates a very different security problem from simply losing a key. If someone deliberately takes your keys, they may know which vehicle they belong to, where the vehicle is parked or even where you live.
Replacing the missing key isn’t enough if the stolen key can still unlock or start the vehicle.
At Lockwise Locksmiths, we can rekey many vehicle locks and reprogram the vehicle’s key and immobiliser system onsite, so the stolen keys can no longer be used in the same way. In many cases, there is no need to organise a tow truck or take the vehicle to a dealership.
Our automotive locksmiths service Brisbane Southside, Logan, Browns Plains and surrounding areas from our Hillcrest workshop, providing vehicle security solutions after keys have been stolen.
What Should You Do If Your Car Keys Are Stolen?
If you believe your keys have been stolen rather than simply misplaced, treat it as a vehicle security issue.
Queensland Police advises that if car or house keys are stolen, owners should have locks replaced or keyless security reprogrammed immediately, specifically warning that offenders may return after the initial break-in. Queensland Police Service
That’s an important distinction.
Getting another key made solves the problem of you not having a key.
Rekeying and reprogramming the vehicle addresses the problem of someone else still having one.
Can a Car Be Rekeyed After the Keys Are Stolen?
Yes. Depending on the make, model and security system, an automotive locksmith can often change both the mechanical and electronic sides of the vehicle’s key system.
Modern car security generally needs to be considered in two parts.
The mechanical key operates components such as the driver’s door lock and, on some vehicles, the ignition. If the vehicle uses conventional mechanical locks, these can often be rekeyed so the stolen blade no longer operates them.
The electronic key, transponder or smart key communicates with the vehicle’s immobiliser or keyless-entry system. Depending on the vehicle, stolen keys can often be removed from the vehicle’s authorised key memory and replacement keys programmed.
For proper security after a theft, we assess both systems, rather than simply supplying another key.
Why Deleting a Stolen Car Key Isn’t Always Enough
This is something that’s easily overlooked.
If we remove a stolen transponder or smart key from the vehicle’s immobiliser system, that can prevent the old key from being used to start the engine.
But the stolen key may still contain a physical emergency key blade capable of mechanically unlocking the driver’s door.
The reverse can also apply. Changing the mechanical lock doesn’t necessarily remove an electronically authorised key from the immobiliser system.
That’s why a stolen-key job needs to be approached differently from an ordinary replacement or spare-key job.
We need to establish what the stolen key can still operate and secure the vehicle accordingly.
Can You Stop the Stolen Key From Starting the Car?
On many vehicles, yes.
Modern vehicles maintain authorised keys within their immobiliser, body-control or smart-key systems. Depending on the manufacturer and system, we can program the vehicle so that the remaining and replacement keys are authorised while the stolen key is no longer authorised to start the vehicle.
The exact process varies considerably between manufacturers.
Some vehicles allow individual keys to be deleted. Others require the complete key set to be relearned. Smart-key and proximity systems can require different procedures again.
This is why we ask for the vehicle make, model and year when you call. We can establish what security system the vehicle uses and what is required to secure it properly.
What About the Door Locks?
If the stolen key includes a mechanical blade, the physical locks need to be considered as well.
Where practical, we can rekey the vehicle’s mechanical locks so the original stolen key blade no longer operates them.
Depending on the vehicle, this can involve changing the lock combination rather than simply replacing every lock assembly.
The objective is straightforward:
The person holding the stolen key should no longer have the same access to your vehicle.
Exactly what needs changing depends on the vehicle’s lock, immobiliser and keyless-entry system.
Do I Need to Tow the Car to a Dealer?
In many cases, no.
This is one of the major advantages of using a properly equipped mobile automotive locksmith after your keys have been stolen.
Lockwise can carry out many car lock rekeying, replacement key and immobiliser programming jobs onsite. We bring the required key-cutting and programming equipment to the vehicle.
That can avoid organising a tow truck simply because you no longer have a secure set of keys.
This is particularly useful when the vehicle is sitting at home after a burglary or when the keys have been stolen somewhere else and you don’t want to leave the vehicle unsecured.
My House and Car Keys Were Stolen Together – What Should I Do?
This deserves particular attention.
If a bag, handbag or set of keys containing both house and car keys has been stolen, especially with identification or information revealing your address, both your home and vehicle security should be reviewed.
Queensland Police specifically recommends replacing locks or reprogramming keyless security when keys are stolen because offenders may return. Queensland Police Service
Lockwise provides both automotive and residential locksmith services, which means we can assess the car keys as well as the security of your home’s locks.
If the keys were taken during a burglary, don’t assume that recovering the vehicle or simply getting another car key resolves the security risk.
Car Theft Is a Real Problem in Queensland
This isn’t a theoretical concern.
The Australian Bureau of Statistics recorded 17,214 victims of motor vehicle theft in Queensland during 2025. More than half of those vehicles—9,034, or 53%—were taken from residential land or an outbuilding. Australian Bureau of Statistics
Nationally, the ABS estimated that around 64,400 Australian households experienced motor vehicle theft during 2024–25. A residential location was the most common location reported for the most recent vehicle theft incident. Australian Bureau of Statistics
Those figures don’t mean every stolen vehicle involved stolen keys. They do demonstrate why maintaining control over who has a working key to your vehicle matters.
If you know a key has been deliberately stolen, you have an opportunity to secure the vehicle before that key can potentially be used again.
What If I Still Have a Spare Key?
Keep it.
Having a remaining working key can sometimes make the job easier, depending on the vehicle.
But having one good key doesn’t make the stolen one harmless.
We can assess whether the remaining key can be retained when the vehicle is reprogrammed and whether its mechanical blade needs to be changed as part of rekeying the locks.
The important point is to tell us exactly which keys were stolen and which keys you still have.
What If All My Car Keys Were Stolen?
That’s also something an automotive locksmith can often deal with.
An all-keys-lost situation generally requires us to attend the vehicle because a new key needs to be generated, cut and programmed to the car.
If the keys were stolen, however, there’s an additional security consideration: we aren’t simply trying to get the vehicle running again.
We need to consider how to prevent the stolen keys from continuing to operate the vehicle.
That can include programming replacement keys, removing old electronic keys from the authorised system and rekeying mechanical locks where appropriate.
Do You Need to Replace Every Lock on the Car?
Not necessarily.
Automotive locks are different from many residential locks. Depending on their construction and condition, existing vehicle lock cylinders can sometimes be reconfigured or rekeyed to a different mechanical key combination.
That can allow us to retain original lock components while changing the key that operates them.
There are exceptions, and some vehicles require replacement components or different procedures.
Our approach is to determine what actually needs changing rather than automatically replacing parts that can safely be retained.

FAQs
Can you rekey a car if the keys have been stolen?
Yes, many vehicles can have their mechanical locks rekeyed and their electronic key system reprogrammed after keys have been stolen. The exact procedure depends on the vehicle.
Can you disable a stolen car key?
On many vehicles, a stolen transponder, remote or smart key can be removed from or excluded from the vehicle’s authorised key system. This can prevent it from starting the vehicle, although the mechanical key blade also needs to be considered.
Will deleting the stolen key stop it unlocking the door?
Not necessarily. An electronic key can be disabled from starting a vehicle while its physical key blade may still operate a mechanical door lock. That’s why we assess both electronic programming and mechanical rekeying.
Do I need a tow truck if all my car keys were stolen?
Often, no. Lockwise can perform many all-keys-lost and stolen-key jobs onsite, including generating, cutting and programming replacement keys.
Should I rekey my car if my keys were stolen during a burglary?
It’s worth treating the vehicle as potentially compromised. Queensland Police advises having locks replaced or keyless security reprogrammed immediately when keys are stolen because offenders may return after an initial break-in. Queensland Police Service
Can you rekey my house and car after my keys are stolen?
Yes. Lockwise provides both automotive and residential locksmith services. This can be particularly useful when a stolen keyring contained both your house and vehicle keys.
