What cars have key activated seat adjustment?

There aren't many modern cars that offer key-activated seat adjustment in the way that some older models might have had a simple, limited adjustment tied to the key fob. Most memory seat systems now use the driver's door panel controls and/or the car's infotainment system to store and recall settings. The key fob might *initiate* a sequence (like unlocking the car and automatically moving the seat to a pre-set position) but the actual adjustment is done by the seat motors themselves, not directly by the key.

So, while you won't find a car advertised as having "key activated seat adjustment," some luxury cars *might* have a feature where certain seat positions are linked to the driver's profile stored in the key fob. This isn't a direct adjustment by the key, but rather the key triggering the recall of a pre-programmed position. This would typically be paired with other memory functions like mirrors and steering wheel position.

To find out if a *specific* model has this type of linked memory feature, you would need to consult the owner's manual or the manufacturer's website for that vehicle. Older models from the late 90s and early 2000s might have had simpler systems closer to what you are describing, but those are becoming increasingly rare.
