The push button system of gear selection was used on all Chrysler lines beginning with the 1956 model year, including Plymouth, Dodge, DeSoto and Chrysler, including their compact models.
The 1956 Chrysler Corporation cars came with “pushbutton automatics” – rather than moving a lever or turning a knob, car owners could push the button for the gear they wanted. The buttons used cables to change the transmissions‘ fluid paths.
Chrysler is credited with the first push-button automatic transmission with their two-speed Powerflyte introduced in the 1954 models and offered until 1965.
When the 1958 Edsel launched in the late summer of 1957, the Edsel became the first and only Ford division to launch an electro-mechanical push–button transmission system, which it trademarked as Teletouch. Teletouch placed the transmission buttons in a ring within the center of the steering wheel.
3. Key programming.

In keyless cars this can be used to start the engine as well as unlock the doors.
Is My Car Keyless Entry? If you have to push a button on your car keys to enter your car, you are not at risk of being “hacked”. Only cars with a keyless entry system can be stolen using so called “relay” equipment. Keyless entry cars allow the driver to unlock and start the car with the key fob still in their pocket.
