Lexus keys — what you should know
Lexus shares Toyota's underlying key architecture with the smart key system across most of the range. The RX has consistently been one of the most stolen vehicles in Ontario, almost entirely through relay attacks on the proximity key. We supply and program Lexus smart keys and fit OBD port locks, which block the separate route of programming a fresh key through the diagnostic port.

Lexus keys — questions
Can you make a Lexus key if I have lost all of them?
For most Lexus models and years, yes, and at the vehicle rather than at a dealership. TOY48 high-security — we cut from code obtained through authorised channels or by decoding the lock directly, then program to the immobiliser on site. Toyota smart key architecture; proximity across effectively the whole range. We verify ownership before any of it, every time.
What kind of key does a Lexus use?
TOY48 high-security. Toyota smart key architecture; proximity across effectively the whole range. This matters because cutting alone is never enough on a modern vehicle — a key cut without programming works the lock and turns the ignition, and the engine cranks and does not start. Give us the year and model and we will tell you exactly which key your car takes before coming out.
How much is a Lexus key, and how long does it take?
Price follows the key type, not the badge — a transponder key is at the low end, a remote head key in the middle, a proximity smart key at the top because the blank itself is expensive. A spare with a working key present is usually thirty to sixty minutes on site. All-keys-lost takes longer, and several makes impose a manufacturer security wait of ten to sixty minutes during programming that nothing can shorten.
