FAQs — Transponder Key Programming in Toronto
What's the difference between a transponder key and a regular key?
A transponder key has an RFID chip in the head that communicates with your car's immobilizer. Without a programmed chip, the car won't start even if the blade cuts correctly. In Toronto, we serve all areas including Downtown Core, North York, Scarborough.
Can you program a key bought online?
Sometimes. Aftermarket key blanks vary in quality and compatibility. We prefer to supply and cut our own blanks to guarantee compatibility. In Toronto, we serve all areas including Downtown Core, North York, Scarborough.
What is all-keys-lost (AKL) programming?
AKL is required when no working keys exist. We erase all existing key data from the ECU and program a fresh set. It typically costs more due to additional steps. In Toronto, we serve all areas including Downtown Core, North York, Scarborough.
