How Lexus immobilizers work
Lexus follows Toyota's transponder generations but adopted smart keys earlier and more widely. RX, ES, IS, GX and NX are mostly proximity-key vehicles from the late 2000s onward, registered to the smart-key system rather than a simple transponder.
No locksmith can honestly promise every Lexus model and year. Whether a key can be made for yours — and where — depends on the year and system. Call (312) 478-6125 with the year, model and VIN and ask before anyone is dispatched. Mr Locksmith is an independent locksmith and is not affiliated with Lexus.
Common Lexus key types
- Smart key (proximity)
- Transponder key
- Smart card key (select models)
All keys lost on a Lexus
Lexus smart-key all-keys-lost involves registering a new key to the smart-key system and cutting its emergency blade to the door lock. It generally takes longer than a bladed-key vehicle.
Worth knowing
Lexus smart keys hide an emergency blade inside. If the fob battery dies in the cold and the car won't unlock, slide the blade out — the driver's door has a key cylinder, sometimes behind a small cap on the handle.
Before you call about a Lexus key
- The year, model and trim of your Lexus
- The VIN — visible through the windshield on the driver's side, or on the registration
- Whether any working key or fob still exists
- Where the vehicle is: driveway, street, parking garage level or commuter lot
When the technician arrives, expect to be asked for photo ID and proof of ownership — the registration, the title, or a lease or financing agreement in your name.
Car keys by make

Common questions
My Lexus key fob battery died — how do I start the car?
Press the brake and touch the Lexus-emblem side of the smart key to the start button; the car reads it even with a dead battery. Lexus smart card keys on some models have their own backup procedure in the manual.
What does adding a spare Lexus key involve?
Lexus smart keys are added with diagnostic equipment, and some models enforce a security waiting period during registration. A spare added while a working key exists is a simpler job than originating one after all keys are lost.
