Engine will not crank, dash bd lights come on, fuses are ok tried installing new pats transceiver and new battery, no change alternator and relay switch make two fast clicks and thats all when turned to run Was hoping to get the procedures for programing the keys if they are decoded.
Hi, diagnosing a no-start condition requires a logical approach to figuring out what might be preventing your car from starting. First, if the engine won't even crank over when you turn the ignition to START, your car obviously won't start.
When you turn the ignition key to start your car, voltage from the battery flows through the ignition switch to the Park/Neutral safety switch and/or brake pedal or clutch pedal safety switch (you have to push the pedal down before the circuit will complete) to the starter relay or solenoid. When the relay or solenoid is energized by voltage from the ignition switch circuit, it closes a contact that routes more power from the battery directly to the starter to crank the engine. The starter motor spins, pushes the starter drive gear to engage the flywheel and cranks the engine.
If the engine fails to crank, there is a fault in one of the components in the battery/ignition/starter circuit. You have to troubleshoot by checking below..
Programing a car key isn't something that just anyone can do. That's why replacement car keys can be expensive. When you buy replacements keys from the dealership, you are not just paying for the cut car key, but for the programming of the small electronic chip inside of the key.
The dealership programs the chip with a special tool. Some car keys can be programmed with very simple steps while others need special diagnostic equipment to be connected to the car's computer.
