Key coding guide
Lost your car keys in Adelaide? What happens next
Losing every key to your car feels like a disaster. It is not. Here is what actually happens, step by step, with no panic and no run-around.

First, take a breath. Losing your car keys is common and it is fixable. You do not need a tow truck, and on most vehicles you do not have to get the car to a dealer to have a new key made. What you need is a clear head and the right information ready to go.
This guide walks through exactly what happens when every key is gone, so there are no surprises. It is written for Adelaide drivers, but the process is the same wherever you are.
The first move
The single most useful thing you can do is call or text with your make, model and year. That one detail decides almost everything about the job: what key your car uses, whether it can be programmed without the dealer, and how long it takes.
You do not need to explain the whole story on the first message. Model and year is enough to start. From there you get a straight answer on whether the car can be done and what to expect. If your vehicle is one of the newest high-security platforms that has to go to a dealer, you will be told that honestly rather than strung along.
What an all-keys-lost job involves
When you still have a working key, making another one is a copy job. It is quick because there is a key to program from. When every key is gone, there is nothing to copy, so it becomes what the trade calls an all-keys-lost job.
All-keys-lost means the immobiliser side is set up from scratch and a fresh key is programmed to the car. The immobiliser is the electronic gatekeeper that stops the engine starting unless it sees the right chip. Getting a brand new key recognised by it is more involved than copying an existing one, which is why it takes longer and costs more.
On a lot of mainstream vehicles this is routine work. What changes it is the make, model and year, which is exactly why that detail comes first. Coverage genuinely varies from one model and year to the next.
What to have ready
A few things keep the job moving and prove the car is actually yours. Have these ready before the work is booked:
- Registration or VIN. This lets your vehicle be checked so the right key and the right method are lined up.
- Photo ID. Ownership is confirmed before any key is programmed. It is a simple check, and it is what stops a stranger having a key made for a car that is not theirs.
- Your make, model and year. Send it ahead so the right key is ready when you are booked in.
That ownership check matters. It protects you. Anyone who offers to program a key with no proof of ownership is not doing you a favour, they are putting every car they touch at risk.
Why texting the details first saves time
Texting your make, model and year before anything else does two useful things. It lets coverage and the key type be checked in advance, so you get a real answer and a quote without back and forth. And it means that when you are booked in, the right key and the right plan are already sorted, so there is less waiting around for you.
A photo of the old key, if you happen to have a spare fob or the key from the logbook, can help too. It confirms the exact key type at a glance. For more detail on how a fresh key is coded to the car, see car key programming in Adelaide.
What it costs, honestly
There is no single price, because it depends on the vehicle and the type of key. A basic transponder key costs less than a smart or proximity fob. All-keys-lost costs more than a spare because there is more setup involved. Prices are not guessed over a guide like this, they are quoted against your actual vehicle before any work starts.
Here is the lesson worth taking from all of this: once you are back to a single working key, get a spare made straight away. A spare is the cheap, simple version of the job, and it means you never have to go through an all-keys-lost recovery again. That logic is worth a read on its own in why one spare now beats all-keys-lost.
