How do you program a 2005 dodge neon key?

To program a key for a 2005 Dodge Neon, you typically need two working keys. Insert the first key into the ignition and turn it to the "On" position without starting the engine for about five seconds, then turn it off and remove the key. Insert the second key and repeat the process. After the second key is programmed, you can then insert the new key, turn it to the "On" position, and it should be programmed to start the vehicle. If you don't have two working keys, you'll need a professional locksmith or dealership to program a new key.
