If you didn't have the key made at the dealer, then it will not start because the new key doesn't have a chip in it and is not sending the right codes to your computer. If you had the key made at the dealer then they programmed the wrong code in to your key or they need to re-program the key or they need to re-program the code in the computer to sync up with the code on the key.

    I agree but I wasn't thinking of going so far as to flash the whole computer. When you try to start it, does it just click or does it actually move the pistons?

    Alright spike26996 before you go throwing your weight around lets get something straight. You don't know my experience your attempt to flame me makes me question yours.
     I know which keys you are talking about and they are out dated. These keys have micro chips that communicate with the cars PCM via radio frequency.  I have busted used keys open and found little micro chips in them not just a piece of silicon attached to a piece of metal if you want and example that would be easy for you to find is to look at any newer key made by VW, Audi, Mercedes, Nissan, Toyota, Lexus, Acura,  etc. 

    Those keys with simple contact resistors evolved into keys with, yes, chips in them and those lasted for a short while until automakers got smart and realized that they don't even need they "key" part of they key.  I believe the early 2000's Corvettes were the first cars to utilize "chips" in the keys not just resistors. And that is why automakers can justify charging upwards of $300 for a key.

Your ignition will only recognise the original key because of its resistance. you need to order a new key from the manufacturer.

    ntruji11 you're wrong. keys dont have 'chips" in them. they dont send any codes to your computer. your computer only registers the resistance of the key you put in the ignition. if your key's resistance is wrong the car will not start. you can do a relearn on the computer and get it to recognise the resistance of your new key but as far as a chip in the key thats gotta be the funniest thing i have ever heard. some keys do have a piece of silicon on the side of them that attach a piece of metal to the key to give it a higher resistance but it is not a chip like in a computer.

What is the code p0174 and p0173 in my 1998 accura rl

That's what happens when you change parts based
on a code & never test anything

Both codes are for bank #2 on the engine

One is Fuel Trim Malfunction & the other
is Too Lean (all the same issue)

Need a repair shop to properly diagnose

No need to tell me that it was at a shop already

THEY FAILED TO FIX IT--stupid,sloppy workmanship

NO TESTING --to find route cause of codes

I lost the keys to an Acura rl 2000 I bought a new original switch with a red and a black key I already istalled but the car won't start

The keys need to be programmed to the immobilizer. Replacing the switch was unnecessary. Keys can be made to the existing locks.

Lost keys for my mazda 3 2004

The only thing you can really do is go to the dealership with the VIN of your car, and he can get you new keys. They're going to be expensive, though. You don't have a keyless entry? If you did, you could find a way to turn your car on through fumbling with the ignition, but, you may ruin it, not a very wise choice.

2004 Taurus My extra key would not start the car and has not been used for months because of this problem (it would crank but not turn over) so I went to dealer to get a new back up key made (two days...

Need to take it back to the dealer so that they can program both keys correct. there should not be any more charges for this being they did not do it right the first time.
