I lost all my keys and remote. How do I find the key code so i can get another key made. I tried carfax and the want to much money just to no my code and i dont know how to find it in the nissan data base. Please help!?

for a start,the transponder KEY, HAS to be coded into the car to start it.the remote is a seperate item but works in conjunction with the key.buying a seperate system is a waste of money,as it CANNOT be used in conjunction with the fitted system.buy a remote and get it coded with the spare(s) into the car, by a dealer that can do the job.the alarm works this way....the remote has TWO codes one fixed the other rolling,every time you operate it the rolling code changes(stops others from "learning")the fixed code allows the key to be recognised when put into the ignition and start the car(if the remote battery goes flat you can still start the car with the key but the alarm may sound if the doors have been locked by the remote).without the remote/key the car is effectively dead.stops theives from stealing your car cos they need to replace the whole ingnition system to get it going.

buy new remotes then have the keys/remotes reprogrammed.as your celica has a rolling code once done, only you can start it with your remotes/keys.(a rolling code means that every time you lock the car with the remote one of the two codes in the remote changes,so only you can start the car)

You'll find the prices on eBay very reasonable for key blanks & remote units. If you have the transponder key, you'll still save money buying the key elsewhere & having it programmed at your dealer.

I use eBay often & looked this up for you:

Keyless Remote: item # 320484718788 24.99 + 7.48 S&H w/programming instructions.

Ignition Key: Item # 250577989265 9.95 + 4.95 S&H see this one for detailed programming information.

Of course there are many other places to buy the keys & the remotes, I just like the buyer guarantee from PayPal.

good luck.

The green key light on the dash is your immobilizer system. If it flashes at you while you are cranking (no start). This means the key that you are using is not programmed to the immobi control unit. Try using another key. if all other keys are lost you'll have to get it down to you local honda dealer. it takes a special honda scan tool to program these keys to the control unit. If you don't want to spend money on a tow truck, ask you dealer about the Brake Code. This is a code specific to each vehicle. If your keys are lost/stolen you can input this Brake Code into the control unit by using your e-brake (special procedure). this will give you 10 free starts to get it to your dealer. (limp-in mode).

your tacoma keys were specially coded for that very truck you are driving and the code on the key communicates with your ecm brain computer. either a dealer or a licensed stereo alarm shop can remedy this for you.

You can try Carfax.com They may have the key code unless the door keys have been replaced. Good luck and hope this helps. 

key code is on metal tag or plastic tag in glove box with owner manual packet. Also, dealer who sold car new has code in sales folder.
ALso, call Ford Customer service. They may have it. Kind of old though, but try.

try putting key in ignition turn to on position
then press lock & unlock several times slowly if door locks cycle up & down after 1st press it lost code and is now resynconised.
now try remote with all doors closed and key out of ignition
if this dont work need to register key(program)back into system which dealer must do with Tech2 if round heart shapped remote
