VIN / Build Split
VIN pos 4-8 identifies model/engine/restraint. Jeep WMI: 1C4 (Jeep). Position 4-5 = model. Position 10 = model year code.
Use vehicle lookup when you know the year, make, and model. Use quote when the car is in front of you and the symptom matters more than the catalog page.

ADAS calibration pricing for a 2021 Jeep Grand-Cherokee depends on which of its 7 documented systems need work after a repair. This vehicle is documented with Forward Camera (Monocular), Forward Radar (77GHz), Blind Spot Monitor Sensor - Left (BSM), Blind Spot Monitor Sensor - Right (BSM), and BDC (Body Domain Controller - ADAS Gateway). 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 and we return a number within 4 hours.
Yes. The 2021 Jeep Grand-Cherokee 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: 68222 877AA. Bench-only or in-vehicle - both paths are supported. Send the part number and a description of what triggered the light, and we will provide a quote and ETA.
After windshield replacement on a 2021 Jeep Grand-Cherokee, Forward Camera (Monocular), Forward Radar (77GHz), and Surround-View Camera System (if equipped) rely on the forward-facing camera and require recalibration before the systems return to operation. We perform the calibration on-site (DFW Metroplex) with OE target fixtures or via mail-in for the front camera/radar module.
Most 2021 Jeep Grand-Cherokee jobs complete same-day once the vehicle or module arrives. This vehicle has roughly 27 programmable modules documented in our database (6 ECU, 4 BCM, 2 TCU, 2 ABS, plus IPC/SAS/gateway/accessory). Module-bench work (ECU clones, BCM reprograms, SRS resets) ships back inside 1-3 business days including return shipping. ADAS calibration is on-site for DFW or mail-in for the front module.
Both. We run a mobile unit across the DFW Metroplex for on-vehicle work (ADAS calibration, key programming, IMMO pairing, post-repair recoding) and a mail-in bench for module-only jobs (ECU cloning, BCM repair, SRS reset, TCU clone). Quote the work and we will tell you which path is right for the 2021 Jeep Grand-Cherokee.
Every programming, cloning, and calibration job on the 2021 Jeep Grand-Cherokee 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.
Yes - all-keys-lost is supported on the 2021 Jeep Grand-Cherokee. Immobilizer generation on this platform: Chrysler RFHUB/SKREEM v2 (128-bit rolling code). 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.
We program, clone, repair, or replace the full programmable-module stack on a 2021 Jeep Grand-Cherokee. For this vehicle our database documents:
Infotainment on this platform: Uconnect 4C. Send the VIN and the operations performed and we will confirm support and pricing.
Send your VIN and we'll confirm exact module support and pricing for your specific vehicle within 4 hours.
1-year unlimited warranty on every flash and calibration.
