Transponder key programming in Vancouver
When the key turns but the car will not start.
Your new key turns, but the engine will not start. It is missing its second half: the chip has to be registered to your immobilizer. We cut and program chip keys at the vehicle.
What the chip in your transponder key actually does.
If your car key dates from the late 1990s or later, a small transponder chip probably sits in its plastic head. No battery, no buttons, one job: proving to the car that this key belongs.
When you turn the key, an antenna ring around the ignition briefly energizes the chip and reads its code. The immobilizer compares that code with the list of keys it has been taught.
A match lets the engine start. No match, and the engine will not start, or cranks and dies, usually with a key or security light flashing on the dash.
That is why a plain copy can turn your ignition and still leave the engine dead. The blade is only the mechanical half of the key.
Push-to-start smart keys do the same job by radio, with a backup chip the car can read when the fob battery dies. Their remote buttons are a separate system: see key fob programming.
Clone the chip key, or teach the immobilizer a new one?
Cloning copies the code from your working key onto a new chip. The car is never put into programming mode. It treats the copy as the key it already knows.
Registering, or teaching, adds a brand-new key to the immobilizer's list through the diagnostic port or an onboard sequence. The car then knows one more key, with its own identity.
A clone is often quicker and less expensive, but you need a working key and a copyable chip. Many newer encrypted systems cannot be cloned.
A registered key can be deleted on its own later. A clone cannot, because the car sees it and the original as one key. If you ever lose a key, that difference counts.
With every key gone, there is nothing to copy. The car must learn a new key, and lost ones can usually be deleted. That stops them starting the engine. The door locks stay the same.
Transponder chip generations, from fixed code to encrypted.
Your car's year and make usually reveal the chip. The chip decides whether your key can be cloned, how it is programmed and what it costs.
Fixed-code chips in older transponder keys
The first generation sends the same code every time you turn the key. These are the simplest chips to copy and program, and a working key can usually be cloned on the same visit.
Crypto chips with rolling challenge codes
The car sends a challenge. The chip answers with a calculated response that changes each time. Copying one takes more equipment, and some can only be cloned after reading data from the car.
Encrypted transponder chips with dealer-level security
Newer systems use stronger encryption. On some makes, no key is added until the manufacturer releases a security code against proof of ownership. If yours is dealer-only, you hear it when you call.
Aftermarket transponder chips that emulate the original
Where an original chip is scarce, an aftermarket chip can often be set up to behave like it. Where the original is the better choice, we say so.
Transponder key prices start with the chip and end with what is already on your ring.
The $75 mobile service call is never the whole bill. Chip key work is quoted per vehicle, on top of it.
See starting pricesThe chip generation and how long the immobilizer takes to accept it
Fixed-code chips are the simplest. Some encrypted systems make the programmer wait out a security timer, set by the car, before it accepts a new key. That wait is part of the job.
Whether the transponder key also needs cutting
A turn-key blade is cut to the key code or decoded from a lock. Laser-cut blades take more machine work than edge-cut ones. Push-to-start keys usually need only a hidden emergency blade cut.
A cloned blank or a fresh key registered in the immobilizer
A clone skips the car's programming procedure, so it is usually the less expensive route. A registered key takes longer to set up.
A programmed key already on the ring changes the job
One working key makes a spare much simpler. On some vehicles, the onboard way to add a key only works with two working keys present. With none left, it becomes a car key replacement job.
Transponder keys cut and registered the licensed way. No ECU swaps, no bypass modules.
Your new key is registered through the OBD port with our diagnostic equipment, or by the onboard sequence your make supports. We confirm which method your car needs when you call.
A bypass module defeats the theft protection the immobilizer exists for. A swapped engine computer brings another car's key data with it. We do neither: your own immobilizer learns your new key.
Registering a key hands over the car, so ownership comes first. Have registration or insurance papers in your name, photo ID that matches them, and the VIN.
Before you take the keys, we check that each one we programmed starts the engine and clears the security light.
Our shop at 929 Drake Street opens soon; every job is mobile until then. No dealer tow: the car stays put, from a Downtown parkade to a Burnaby driveway, anywhere in the Lower Mainland.
What people want to know about chip keys and immobilizers.
Why does my newly cut chip key turn but not start the car?
The blade fits, but the chip is unregistered, or the copy has no chip. The immobilizer reads an unknown key and blocks the start. If the chip suits your car, it can often be programmed.
Can a transponder key be cloned without the car present?
Often, with a working key and a copyable chip type, since the code is read from your key. Some crypto chips also need data from the car, and registering a new key always does.
Is an immobilizer key the same as a transponder key?
In practice, yes. The transponder is the chip in the key, and the immobilizer is the system in the car that reads it. "Chip key" means the same thing.
Can you program a transponder for a car with a swapped engine computer?
Sometimes. A second-hand engine computer may still hold its old car's key data, so it rejects your keys. Some can be matched to your keys. Others need the dealer. Mention it when you call.
Does a transponder chip wear out or lose its code?
Rarely. The chip has no battery to die. Failures usually trace to a cracked key head that lets the chip fall out, or to the antenna ring around the ignition. We test both.
