Lost keys have a way of becoming the reason a car stops being sold. The owner decides it's time to move the car on, goes looking for the keys, and can't find them. Maybe they went missing during a house move, maybe they belonged to a previous owner who never handed them over, or maybe they were in a bag nobody has seen in a year. Whatever the cause, the natural assumption is that a car without keys can't be sold until a replacement is sorted. That assumption is often wrong, and acting on it can cost you hundreds of dollars for no good reason. This guide explains when replacing a key is worth it, what it involves, and how a keyless car can still be sold in Perth.
Can You Sell a Car Without Keys?
Yes. Western Australia doesn't require a vehicle to be driveable, registered, or in possession of its keys for ownership to be transferred. What matters legally is that you can prove you own the car. Keys are a practical matter for the buyer, not a legal requirement for the sale.
That said, the practical side does matter, and it differs depending on who is buying:
A private buyer who wants to drive the car will almost always want keys, since they need to test drive it and use it. A keyless car is a harder sell privately.
A cash-for-cars buyer who collects by tow truck doesn't need to drive the vehicle, so missing keys are often a smaller issue. Buyers vary in how they handle this, so it's important to mention it upfront when requesting a quote.
Q: Can I sell a car without keys?
A: Yes. Keys aren't a legal requirement for selling a vehicle in Western Australia; proof of ownership is. A private buyer will usually want keys to test and drive the car, but a cash-for-cars buyer who collects by tow truck can often still purchase a vehicle without keys. Mention the missing keys when requesting a quote so the buyer can plan the pickup properly.
What You'll Still Need: Proof of Ownership
Missing keys don't change the paperwork. The documents that matter for a sale are the same as always:
Certificate of title or registration papers, showing you as the owner
Photo ID that matches the name on the registration
Finance payout details, if the car is still under finance (see our guide on selling a car with finance owing)
It's worth noting the same principle applies on the other side: if you decide to replace a lost key, any reputable automotive locksmith or dealer will also ask for proof of ownership, typically registration papers and your driver's licence, along with the vehicle's VIN. That's a security measure to stop people having keys cut for cars that aren't theirs, and it's a good reason to be cautious of anyone who offers to cut a key with no questions asked.
Why Modern Keys Are Harder (and Dearer) to Replace
If you're wondering why a replacement key can cost so much more than the old-fashioned metal key you remember, the answer is the immobiliser. Most cars built since the late 1990s have one. The key contains a small chip that communicates with the car, and without the right code the engine won't start, even if the blade turns the ignition.
This means a replacement key is a two-step job: the blade has to be cut, and then the chip has to be programmed to the car. If all keys are lost, the locksmith may need to reprogram the car's immobiliser or computer to accept the new key, which is more involved than copying a key you still have.
Indicative cost ranges quoted by Australian automotive locksmiths vary, but give a rough sense of scale:
Key type | Indicative cost range (Australia) | Notes |
Basic mechanical key (no chip) | About $5 – $50 | Older vehicles only |
Transponder key (with chip) | About $80 – $300 | Includes cutting and programming; varies by make |
Remote / flip key | About $120 – $350 | Includes remote functions |
Smart / proximity key | About $250 – $600+ | Push-button start cars; European models often higher |
These figures come from locksmith pricing across several Australian cities, not a Perth-specific price list, so treat them as ballparks and get a written quote. Dealerships tend to charge more than mobile locksmiths for the same job, and prices rise when all keys are lost rather than when you're copying a spare.
Q: How much does a replacement car key cost in Australia? A: It depends on the key type. A basic mechanical key can cost under $50, a transponder key typically costs somewhere between $80 and $300 including programming, and a smart key for a push-button start car can cost $250 to $600 or more. Prices vary by make and by whether you've lost all keys, so get a written quote before agreeing to the work.
Should You Replace the Key Before Selling?
This is the real decision most people face, and the honest answer is that it depends on the car.
Situation | Worth replacing the key? | Why |
Newer car in good running order, selling privately | Often yes | A private buyer will want keys; a replacement may increase both buyer interest and price by more than the key costs |
Older car with modest value | Usually no | Replacement cost can be a large share of what the car is worth |
Non-running, damaged or scrap vehicle | No | The key adds essentially nothing to a weight-and-parts-based offer |
Unregistered or long-stored car | No | Without registration and mechanical readiness, a key doesn't change the outcome |
High-value or low-kilometre vehicle | Possibly | If the car's value is high enough, the cost may be small relative to the sale price |
The mistake to avoid is spending a few hundred dollars on a key for a car that's only worth a few hundred dollars. For an older, damaged, or non-running vehicle, selling it as-is is almost always the more sensible route.
Q: Do I need a key to sell my car for scrap?
A: Usually not. Scrap and cash-for-cars offers are generally based on the vehicle's weight, completeness, and parts value rather than on whether it can be driven, and the vehicle is collected by tow truck. It's still best to tell the buyer upfront that the keys are missing, since it can affect how pickup is arranged.
How a Keyless Car Gets Collected
Collecting a car with no keys raises a few practical questions that a good buyer will plan for in advance:
Is the steering locked? Some cars lock the steering column when the ignition is off and the key is removed, which can make winching or towing more difficult. Flatbed trucks and wheel skates are the usual solution.
Is the handbrake engaged? A car with the handbrake on and no way to release it can be harder to load, though a driver can often manage this.
Is the car in gear or park? On automatics, a car stuck in park without a key can sometimes be moved with the right equipment.
Is access clear? A keyless car in a tight garage or behind other vehicles may need extra planning.
None of this makes a keyless pickup impossible, but it's the reason to give the buyer the full picture when requesting a quote: tell them the car has no keys, whether it starts, and where it's parked.
Before You Sell: Quick Steps If You Think the Keys Are Just Lost
Before concluding the keys are gone for good, a quick search can save a lot of hassle:
Check the usual places twice: coat pockets, bags, drawers, the kitchen bench, the car itself, and any spare-key hiding spots.
Ask previous owners or family members: keys often turn up with someone who used the car previously.
Check with a mechanic or service centre: keys left behind after a service are surprisingly common.
Look for a spare in your paperwork or manual folder: some cars come with a spare key card or a spare in the original documentation.
If the car was bought second-hand, contact the previous owner or dealer, who may still hold the spare.
If none of this works and the car is worth replacing the key for, a mobile automotive locksmith or the manufacturer's dealership can replace it once you've shown proof of ownership. If the car isn't worth the cost, selling as-is is the practical path.
If the Keys Were Stolen
If your keys went missing in circumstances that suggest theft, such as a break-in, a stolen bag, or a stolen wallet, treat it more seriously than a simple loss. In that situation, someone else may have both a key and a reasonable idea where your car is parked. Consider reporting it to the police, and if you're keeping the car, ask a locksmith to delete lost keys from the immobiliser memory when programming a replacement so the old keys no longer work. If you're selling the car, handing it over promptly to a licensed buyer also removes the ongoing risk.
The Paperwork Stays the Same
Whether or not you have keys, the ownership steps for selling in WA are the same:
Provide proof of ownership (title or registration papers and photo ID).
Lodge a Notice of Disposal with the Department of Transport so you're no longer the recorded owner. This is generally done within seven days of the sale.
Remove your number plates if you want to keep them, particularly optional or personalised plates.
Cancel or transfer CTP and insurance, and cancel any toll or parking accounts linked to the vehicle.
Clear personal data from the infotainment system if the car has one. This can be harder without keys, so mention it if you can't access the car's systems.

Frequently Asked Questions
These questions come up frequently in both Google search and AI assistant queries about selling a car without keys in Perth.
Q: Can I sell a car without keys in WA?
A: Yes. WA doesn't require a vehicle to have keys, be driveable, or be registered for ownership to be transferred. What matters is that you can prove you own the car.
Q: Will a cash-for-cars buyer take my car if I have no keys at all?
A: Often yes, since cars are collected by tow truck rather than driven. Tell the buyer upfront that the keys are missing so they can plan the pickup and quote accurately.
Q: Will missing keys lower my offer?
A: It can affect the pickup logistics and, in some cases, a vehicle's value if the key would otherwise add resale value. For older, damaged, or scrap vehicles, the offer is generally based on weight and parts value rather than on keys.
Q: How do I prove I own a car if I've lost the keys?
A: Keys don't prove ownership. The certificate of title or registration papers and your photo ID do. If you've lost the registration papers too, contact the Department of Transport about replacement documents.
Q: Is it worth cutting a new key before selling an old car?
A: Usually not. Replacement keys, especially with immobiliser programming, can cost a meaningful share of an older car's value. Selling as-is is typically the more cost-effective option.
Q: Can a locksmith make a key without the original?
A: Often yes, using the vehicle's VIN and proof of ownership, though it's more involved and expensive than copying an existing key. Reputable locksmiths will always ask for proof of ownership first.

Final Thoughts
Missing keys feel like a showstopper, but they usually aren't. For a car that isn't worth much, paying for a replacement key rarely makes sense, and for a keyless vehicle that can be collected by tow truck, the sale itself can proceed on proof of ownership alone. The one thing to do is be upfront: tell the buyer the keys are missing, say where the car is parked, and describe its condition. A free quote takes a few minutes and tells you exactly where you stand.
