What automobiles have key pad entry systems?

Keypad entry systems aren't common on modern automobiles, mostly phased out in favor of key fobs, smart keys, and smartphone apps. They were more prevalent in the late 1990s and early 2000s, primarily as an *additional* security feature to a standard key system, not as the primary means of entry.

Therefore, there isn't a definitive list of cars that *only* used keypads. To find examples, you'd have to look at models from that era (late 90s - early 2000s) and research their available options. Some cars which *may* have offered keypad entry as an option include certain models from:

* General Motors (GM): Some Buick, Chevrolet, Pontiac, and Cadillac models might have had this option.

* Ford: Some Ford models during that time frame potentially included it.

* Chrysler: Similar to GM and Ford, certain Chrysler, Dodge, and Jeep models could have offered a keypad entry system.

Important Note: Finding a car *currently* equipped with only keypad entry would be exceedingly rare. Most older cars that had keypads would have retained the traditional key entry as well.
