When IS owners call us
A useful example is a key turns or unlocks but the immobiliser does not authorise starting. That kind of symptom shapes what we test first.
The only key has gone
For a lost-only-key IS, we first confirm whether the fitted system supports a mobile all-keys-lost procedure.
IS will not accept the key
Before any new key is suggested for a IS, we check whether the fault sits in the key itself or in how the car is detecting it.
No spare yet
A IS spare is quicker and cheaper while the first key still works.
Why the IS model year matters
On the IS, the year and trim decide which programming route we use.Transponder remote keys on some earlier cars and smart keys on later generations. Coding tells the immobiliser to accept the new key. Remote locking and keyless entry are checked as separate steps, along with the emergency blade. Very new cars sometimes carry restrictions; we tell you upfront if yours does.
How we help IS owners
We keep this page focused on the IS; each linked service explains the wider process, choices and limitations in full.
IS keys are generation-specific
The Lexus IS is a sports saloon. The useful model-specific point is older and newer IS keys require different expectations.
A IS key has to match in three ways: the blade, the electronics and the car's own security records. Generations range from transponder remote keys on some earlier cars and smart keys on later generations.
