2000 daewoo lenganza from friend and he gave me the wronge key and lost the right one

If you want to find the original key code, you would need to contact the dealer with your VIN and owner's detail for them to get the correct one.

If you don't want to do that, then you would have to buy an ignition lock with the key.

All you have to do is take off the trunk key cylinder and have a lock smith make a key from it. There is no prom for the key so it will work.
