Q: I know new lock cylinder comes with keys but is it plug and play or do they have to get programmed?

asked by on June 30, 2017

So the little loop on top of the key (where you would usually hang it from to your keychain) broke off so I'm paranoid of loosing my key. Now I only have one key to the car but also this key slides out the ignition. It locks and unlocks and turns on the car and off( obviously) but it wont stay locked in the ignition while the car is on, I can literally drive the car without the key in the ignition but I do need it to turn it on.
My car has an automatic transmission.
