Lost keys for LEXUS GS300?

[great1]

I lost the only key for my 1994 GS300. Obviously asked the dealer and the person over the phone said to me the best thing i have to do is find the same key. Because new1 wil cost me around a grand.

I tried my best but could not find the key. Then i called a locksmith and he said to me that he can make a new key for me for only 75 pounds. But ask me to take the driver side lock out and send it to him. I Send the lock to him and he send me the new key. Now today i check my new key but its not turning the ignition nor its opening the boot. So i called the locksmith and tell him about the problem and they said if its turning the lock you send us then it should turn the ignition as well. So they can not do anything as they recon there is a problem with the lock.

Now i do not know what to do. Please some expert help me. As its been 3 months car is standing on the driveway. The key is just a key without any button on it.

the key is probably coded for the car. so you need to goto the dealer and get the appropriate key blank.
Honestly, it's best in this case to spend the money for the key at the dealer because they'll get you the right key and if it's coded, they wil code it to the car for you. if they're charging a grand, it sounds like the key is coded. the key might be laser cut as well, upping the price.
you woldn't have had this issue with a camry.
