Hello, This is a sign that your EIS (ignition switch you put the key into) or key are failing. The first thing the dealer will ask: "do you have a spare key". if yes, try it, see if you get the same results. If no, buy one ($200-300, and you can ONLY get it from the dealership. If the key is special order, it will be made in Texas and mailed out in 3 days. If both keys do the same thing, the EIS will likely need to be replaced and programmed, and this will become costly very quickly. To test the IR window on the end of the key, point it at the IR transceiver on the driver door, hold down press and release the unlock button, then press and hold the unlock button. If the windows roll down, the IR portion of the key is good. If the windows don't roll down, look at the tip of the key, and see if there is damage to the little IR window. If it is very damaged, you can order a new shell for the key (just bottons, case, and IR portions), and put the logic board for your key into the new case.
