Hello Hauser

How are you doing? Will it crank when you start the vehicle? I'll be standing by for your response.

Thank you

Relly

Good to hear back from you Hauser. Did the dealer say that they can't rerprogram the key for new codes?

Thank you for that information Hauser. Going with the key is one smart move because it can be the culprit. But what if it still fails with the new key and code? It can be a starter that's about to die that's why it will not at times. Another thing to look at is a failing crankshaft position sensor shown below.

When the crankshaft position sensor begins to fail, the signal it transmits to the vehicle’s computer begins to weaken. If left unattended, the signal will switch off completely. This, in turn, causes the car’s spark plugs to die out, killing the engine. If you are having problems starting your car, it could indicate a bad crankshaft position sensor.

This things should be looked at Hauser if changing the key doesn't resolve the issue. Hope this helps. Please let me know if there's anything else I can add or help you with.

Thank you

Relly

10 years is reasonable enough for the crankshaft position sensor failure Hauser. The sensor will cost at around $14 to $20 plus your mechanic's labor. Let's just hope that it works on the new key Hauser. At least you know what to do if the new key doesn't resolve the issue.

Is there anything else I can add or help you with Hauser?

Relly

You're welcome. Happy New year and goodluck!

Thank you
