Use make as the first filter, not the final answer
Select the vehicle make above, then use its guide to prepare the exact year, model, trim, production market, start method, remaining keys, and symptoms. Model generations can change key architecture within the same nameplate, and visually similar fobs can contain different boards, frequencies, chips, blades, or feature sets.
The current catalog and legacy sections are separated to make browsing easier, not to make service promises. A make appearing here does not guarantee local routing, inventory, a particular procedure, or mobile support for every configuration. The vehicle facts and requested outcome still control the next step.
When the vehicle is used for work, delivery, caregiving, or a scheduled trip, explain the operational constraint without assuming it creates a guaranteed arrival time. Ask for a realistic routing update and decide whether towing, a dealership appointment, roadside assistance, or another documented alternative should remain available. A clear fallback plan can be more valuable than repeatedly calling providers who have not confirmed compatibility or travel.
For a newly purchased used vehicle, ask how many credentials the seller represented, whether every supplied key starts and unlocks the vehicle, and whether missing credentials should be removed from the authorized set where the platform supports that action. Keep purchase and ownership records available. Do not assume that a remote with matching buttons belongs to the vehicle merely because it was handed over with it.
