FREQUENTLY ASKED QUESTIONS

FAQ

How much does ADAS calibration cost for a 2021 Lexus IS?

ADAS calibration pricing for a 2021 Lexus IS depends on which of its 3 documented systems need work after a repair. This vehicle is documented with Pre-Collision System (PCS) with Pedestrian/Cyclist/Motorcyclist Detection, Lane Keep Assist / Lane Departure Warning (LKA/LDW), and Blind Spot Monitor / RCTA. We provide a fixed quote after confirming the operations performed - send the VIN, the repair scope (windshield R&R, bumper work, alignment, collision), and any DTCs so the quote response can include a real number.

Can you reset the airbag light on a 2021 Lexus IS?

Yes. The 2021 Lexus IS uses a factory SRS control module that we support. We read and clear stored crash data, then restore the module to factory status so the airbag warning light goes out and the system returns to full operation. Reference part number on this vehicle: 89170 76100. Mobile diagnosis and programming are the active service path. Mail-in bench intake is temporarily unavailable. Send the part number and a description of what triggered the light, and we will provide a quote and scheduling window.

What is needed after replacing the windshield on a 2021 Lexus IS?

After windshield replacement on a 2021 Lexus IS, Pre-Collision System (PCS) with Pedestrian/Cyclist/Motorcyclist Detection and Lane Keep Assist / Lane Departure Warning (LKA/LDW) rely on the forward-facing camera and require recalibration before the systems return to operation. We perform the calibration on-site in the DFW Metroplex with OE target fixtures. Mail-in intake is temporarily unavailable.

How long does a 2021 Lexus IS module service take?

Most 2021 Lexus IS onsite jobs are typically scheduled within 24-48 hours once vehicle readiness, access, and route timing are confirmed. This vehicle has roughly 11 programmable modules documented in our database (3 ECU, 2 BCM, 1 TCU, 1 ABS, plus IPC/SAS/gateway/accessory). Mobile module work and ADAS calibration are scheduled in the DFW service area after quote review. Mail-in module intake is temporarily unavailable.

Do you cover the 2021 Lexus IS on-site, or is this mail-in only?

We run a mobile unit across the DFW Metroplex for on-vehicle work (ADAS calibration, key programming, IMMO pairing, post-repair recoding, and supported module work). Mail-in module intake is temporarily unavailable. Quote the work and we will confirm the active service path for the 2021 Lexus IS. Do not ship a module unless support confirms next steps.

What kind of warranty do you offer on 2021 Lexus IS programming?

Every programming, cloning, and calibration job on the 2021 Lexus IS is backed by a workmanship warranty covering the scope of work we performed: 1-year unlimited on all flashes, clones, and ADAS calibrations. If a module we programmed or a calibration we performed fails to function as expected, return it and we restore it at no charge. The warranty covers our work; it does not cover unrelated mechanical or electrical failure of the module itself.

Can you program a 2021 Lexus IS with no working keys (all-keys-lost)?

Yes - all-keys-lost is supported on the 2021 Lexus IS. Immobilizer generation on this platform: G4 (DST-AES). Adding a key (with a working key already in hand) is also supported - typically faster and less expensive than an all-keys-lost reset. Submit the VIN and we will confirm the procedure and quote before scheduling.

Which modules on a 2021 Lexus IS can you actually service?

We program, clone, repair, or replace the full programmable-module stack on a 2021 Lexus IS. For this vehicle our database documents:

3 engine control (ECU/PCM)
1 transmission control (TCU/TCM)
2 body control (BCM and related)
1 ABS / brake control (EBCM)
1 immobilizer / security
1 key & fob
1 instrument cluster (IPC)
1 steering angle sensor (SAS)
3 ADAS module

Infotainment on this platform: Lexus Enform. Send the VIN and the operations performed and we will confirm support and pricing.
