With all the 3 keys it's not possible to start the engine. Batteries on the keys were replaced and it works well to open and closed the doors. The only way to start the car is now to place the key in the central box between the seats, as described to do in case of an empty key battery. What's could be necessary to repair?
low battery, car or fob will cause immobilizer to shut car down and lots more. do you have a scanner to check, ECU and immobilizer? it will tell you more. and probably give you info you are looking for. just make sure you buy one that will talk to you car. there are none that will do all. first use of it will save you. dealer charges around 175.00 just to scan. and they are simple to use.
