Its cheap to get another key made. My local Ford dealership charged me about 100 bucks two cut and program two new keys, and reprogram pats onto my new pcm.

I think its 35-40 per key if I remember correctly.

That would be great! I hope it is a key, a C.P.S., or something simple. I tried to program a key on my own and found out it would not work. Maybe that is the problem. I already checked fuses 5,21,and 34.
Can any one take there key and shake it, to hear if the chip makes noise. Shake it like a salt shaker! I had the key cut at a local hard where store. They had a old key cutter and the key made a rattle noise after. The first key makes noise too. I do not know if the chip shook on the first key before.
More than one key shake reply would be appreciated.

No, there should be no movement. If your chip is rattling around its likely your key is broke! It should be solid. Can you post a picture of your key? Youve got me curious.

You can only hear the noise if you take the key off the chain and put it near your ear.

Every time I try to upload pictures, they are too big of resolution. It is a ilco key. After the hurricane I lost 2 keys in 2 casinos, I worked at doing destruction. Getting paid to destroy stuff rocks.The Ile Of Caprie and the Imperial Palace. People came out and cut keys on site. The key is about 4 years old.


The car went down for a engine rebuild and the second key was ordered. I got lucky and it cranked once after I got the C.P.S. correctly adjusted. She purred with new rockers. But theft light ever since.

My key definitely makes no noise, on or off the key chain

Thanks, for shaking it like a salt shaker.
Do you think I should go for the top ten answers?
