Car wont start after leaving key in ignition,ie went to start car, but phone rang, key in ignition, now wont start.this has happened my wife on several occasions. starts fine on a push

Disconnect one of the cables from the battery. Leave off for 5 min. Reconnect the cable, tighten properly, snug. Computer is now reset. Perhaps that will work....

You need to have your fuel pressure checked. fuel filter, etc.

Is the broken part of key still in ignition? if so it will need the top half of key close to it to run. the top half of key has a chip in it and without it the car wont start if this wae helpful please leave good feed back

Won't start how ? When your the key to the start position what happens ? The engine spins but won't start an run . this a crank no start condition . If nothing happens when you turn the key to start ,this is a no crank no start condition . Need to be clear on this so we know what to have check . If nothing happens when turning the key to start position ,try moving gear selector to neutral - park neutral safety switch . If when you turn the key to start an the engine does spin but doesn't start an run ,check for spark ,fuel pressure . see what's missing .

Sounds like you are losing the power from the battery. Loose connection somewhere between the battery and the fuse box. The car is going into security mode (which prevents the car from starting). This happens when people change the car battery. Leaving the ignition key on for 10 minutes and the security light quits flashing. Car starts. I would be looking at the battery connections and other main power leads going the the relay center. Good luck.

Most likely a bad battery or battery terminal connection.

Did you replace the key switch or the ignition switch behind the key switch?

key code lock out usually happens when you have entered the wrong code too many times leaving the battery connected should allow the timer to run down for 30 mins so you can try again, it is cumulative though so the more you get it wrong the longer you have to wait. make sure battery is fully charged first.

It sounds like you ignition switch went out. I had this happen to my wife a few years ago you turn the key the acceseries turn on but nothing else. this will be a trip to the dealer. did you happen to smell something electrical burning the last time you car was working if so it is the starter switch. you will need to take it to the deales an get a ne w switch which will also involve new keys$$$

leave the key on for about 5 to10 min then try to start. Are reset to computer by leaving the key on for 10 min and try to start the vehical.Do this procese 3 time then it shold reset
