99 dodge dakota security system

The antitheft needs to recognize the master key that it was programmed to accept. If not, the immobilizer does exactly what you are experiencing, no start.

I kind of figured that but the old switch to original key switch when they tried to break into my son's vehicle they totally destroyed that so I had to replace it with a new one which comes a new set of keys along with the new ignition switch so how would I program the vehicle to recognize new keys I mean I still got the original keys cuz he's going to need that for his locks for his doors any suggestions and thank you for your answer

You'll need the services of a locksmith or a dealership to program the car to accept the new keys, no way to get around it. The old keys can't be used because the old lock cylinder is destroyed, and they can't be used with the new lock cylinder.

A mobile locksmith might be your best bet, they can come to you and save you the cost of a tow, and reprogram the car for the new keys.

Found this posted answer to reprogramming your new ignition key after it has been replaced POST BY DavidH25 6 years ago Best Answer Enter your vehicle with your key. Consider using a timer or reliable watch for the following steps. If you use a timer, program it for 10 minutes, 30 seconds. Insert the Dodge Dakota key and turn it to the "On" position. Start your timer. Turn the key back to the "Off" position when the time elapses. This must be done within 45 seconds of the timer going off. If you are using a timer, reprogram it for an additional 10 minutes and 30 seconds. Start the timer again and turn the key to the "On" position. When the countdown is finished, turn the key to the "Off" position within 45 seconds of the time elapsing. Program any additional keys by putting a programmed key in the ignition and turning it to the "On" position for five seconds. Return it to the "Off" position and remove it from the ignition. Place the additional blank key in the ignition and turn it to the "On" positions for five seconds, and then to the "Off" position. Turn it once more to the "On" position and it will be programmed to start your car. If Your Key Won't Program Contact a reliable automotive locksmith. This is best done through a professional organization such as the Associated Locksmiths of America. Bring the key to the automotive locksmith. Remember that there is frequently a substantial discount for every additional key you would like to have programmed after the initial key. This is typically not the case with the dealership. Test your key in your ignition. If it does not work, then the key needs to be reprogrammed. An automotive locksmith should do this for free until you have the right encoding for your key.
