POSIBLE NEED A NEW IGNITION SWITCH THE H KET Y PART

Sound like you have ignition switch problem. You can start with remote then everything should be fine.

ignition keys worn out or ignition switch faulty.

sounds like the lost ket is a PATS key, and the new cut key, while matching tumblers in the ignition is not coded to the PCM to allow starting. recommend check with dealer, have your registration and VIN# ready, dealer can reproduce a PATS key that should start your vehicle.

Start by checking your main ground wire. and also check your main fuse, i believe it is 60amp. GL

Having to replace an ignition switch is common. The ignition switch is solid state so you cant fix it, it will need to be replaced.

spray some WD40 in the ignition and move the steering wheel back and forth while pulling on the key or make sure your vehicle is in park all the way.

more than likely the ignition switch is bad.

lock the car using the key to reset the alarm
