Key information — 2003 Jeep Grand Cherokee

These are candidate key, remote, vehicle-equipment, or immobilizer-system references for this model year. Match the VIN, original key, chassis, build date, trim, ignition type, equipment, and market as applicable before ordering. Separate entries are alternatives or overlapping source applications; do not combine them into one key or treat a candidate as confirmed equipment for the individual vehicle.

About Your 2003 Jeep Grand Cherokee

The model name or year alone does not establish the installed immobilizer, key type, or programming method. Confirm the VIN, market, trim, and any replaced components against the source references and the vehicle.

Confirm your vehicle details and whether any working keys remain so we can quote the applicable service before dispatch.

Before your key appointment

Have your VIN, trim, and any existing keys available. Describe how you start the vehicle: turn a key, press a button, or use both. Tell us whether any working keys remain and whether you need a spare, a replacement remote, or help after losing every key. Include a photo of the original key and its label when available.
