It should have Turned off with the Insert of the Newly Programmed Key. If Not, It may need a Computer Reset. You Can try Pulling the ECM Fuse for 5 Min. to Reset the Computer. If this does not work, Try disconnecting the Battery and Reconnecting. Make sure that you have a RadioCode before Disconnecting the Battery Though. Please Rate My Response! Thanks!

I had that same problem and it took me forever to figure out what was wrong. You are probably using an aftermarket key as was I. The stupid little plastic/metal chip in the shaft of the key is for the security system. Sometimes if you insert the key and turn too fast it sets off the security system. To solve the problem go get another key made from a different key maker, they cost around $15-20. Or, insert the key slowly and turn the ignition slowly. Or go get a good key from the dealer, I've heard it may be ~$50 for this key but it should work the best. FYI I still just use my aftermarket key and just deal with the occasional no start wait 3 min ordeal. Good luck.

First, provided their are no visible coolant leaks and/or loss of coolant with no signs of leaks, I would thoroughly flush cooling system and replace coolant, then check and/or replace thermostat (you can place thermostat in boiling water to check for proper function), if you have tried these 2 steps and still are experiencing overheating you may need to replace your water pump which can be a tricky job if you're unfamiliar and try to do it yourself, however, I could walk you through it if necessary. Also visually check your radiator hoses for bulges, wear ,etc along with heater hoses etc. You may want to also check radiator fins to see if they are dirty/obstructed and clean if necessary. Let me know if I can assist you further and how it works out

I have had the same problem and I have come to the conclusion it is the security system. After 3 minutes the car will start so there is nothing wrong with the battery or starter. I have had it to the dealer a few times and they cannot solve it. It may be the locks on the doors and they may not be resetting properly. I have learned to live with it.
