Transponder & Chip Key Programming — Perth’s Southern Suburbs
A key that's cut but won't start your car just needs programming
Modern car keys have a small chip inside that has to be matched to your vehicle’s immobiliser before the engine will start. A key can be cut perfectly and still leave you stranded if that chip was never paired — a new aftermarket key, a secondhand key that came with the car, or a chip key that’s stopped being recognised.
We carry mobile programming equipment for most makes and models, so we can pair your key to your car on-site — no tow truck, no dealership appointment.
When You Need Key Programming
Common reasons people need a key programmed
Bought a key online or aftermarket
The key’s cut to fit, but it still needs to be paired to your car’s immobiliser before it’ll start the engine.
Secondhand car with an unpaired key
A key came with the car but was never programmed to it — common with private sales and inherited vehicles.
Chip key not being recognised
Intermittent or constant ‘key not detected’ warnings, even though the key turns and the car looks fine.
Fob battery replaced, now won’t start
Some vehicles need the key re-synced to the immobiliser after a battery swap, not just a new battery.
Adding an extra key for the household
Programming an additional key for a partner, teenager, or second driver without duplicating through the dealer.
Dealer quote too high
Dealership programming can run into hundreds of dollars and a multi-day wait — we do it mobile, same day.
What’s Involved
Matching your key's chip to your car
We connect to your vehicle’s onboard diagnostics port and use professional programming equipment to register your key’s transponder chip to the immobiliser — the system that stops the engine starting without a recognised key.
Most makes and models can be programmed on-site in one visit. We’ll confirm your car’s make, model and year before we arrive so we bring the right equipment and can give you an accurate price up front.

Common Questions
Key programming FAQs
Most keys made since the late 1990s have a small chip embedded in the plastic head that communicates with your car’s immobiliser. The engine won’t start unless the car recognises that chip — cutting the metal blade alone isn’t enough.
In most cases, yes. We’ll need your car’s make, model and year to confirm compatibility and bring the right equipment before we head out.
It depends on the vehicle — some cars need at least one working key present to add another, others allow programming via the OBD port without one. We’ll confirm this when you call with your car’s details.
Most vehicles support multiple programmed keys (commonly up to 4–8 depending on make and model) — useful for households with more than one driver.
Sometimes. A few makes need the key re-synced to the immobiliser after certain battery replacements. Call us with your make and model and we’ll talk through it.
Most jobs take 20–40 minutes on-site, depending on the make and model.
