I have a 2005 Town & Country. I only have one remote key. I do not have any other keys.

My little girl likes to play hide and seek with my one key. If I cannot find the key some day, then I'll be forced to have a replacement key made.

If after I have a replacement key made, my little girl brings me the original key, will the original key still work? Or will only the replacement key work?

 

if it has the chip key in it and the person who programed it erased all other keys then no it will not work hop in and give it a try see what it does.
